Om 5:10 UTC draaien we naar het oosten om een omvangrijk windmolenpark op het transect. De koers ligt in het verlengde van een transect dat we van onze Duitse collega's hebben overgenomen: zij nemen deel aan dit onderzoek en varen transecten in de Duitse bocht. In dit deel van de Noordzee wordt het echogram groener door de hoeveelheid deeltjes, plankton of- ja wat eigenlijk? Misschien biedt de camera uitkomst, maar eerst voeren we trek 30 uit op rode schooltjes boven de grond (9:23 UTC): de vangst bestaat uit sprot.</span></p><p><span style="font-family: helvetica;"><i>Wednesday, July 20, 2022 - We take off at 4:06 UTC in an east-southeast direction from 54.11N-031E. At 5:10 UTC we turn east around a large wind farm on the transect. The course is in line with a transect that we have adopted from our German colleagues: they participate in this research and sail transects in the German Bight. In this part of the North Sea, the echogram becomes greener due to the amount of particles, plankton or – yes, what exactly? Maybe the camera will help, but first we do haul 30 on red schools above the bottom (9:23 UTC): the catch consists of sprat.</i></span></p><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEirOugLpF5pABrcKP8jMVV23dKPEFcpxQb2JY3zPNQE3vt7a_jH6uND5--J3YThNAfsKvX3k9JvrJQRyzkEVUQ0pGTaEQuOjo4IpAlOF4dtzsXMkaJZN2e4TQF-7RfH7P9_VQsSaxYtTGrJMeG5DJBn5_nIU8kXKba9M43cNiCgAGEm9TuT2eO2VEWxkA/s1556/Haul30_day20_20220720_38kHz.png" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" data-original-height="859" data-original-width="1556" height="370" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEirOugLpF5pABrcKP8jMVV23dKPEFcpxQb2JY3zPNQE3vt7a_jH6uND5--J3YThNAfsKvX3k9JvrJQRyzkEVUQ0pGTaEQuOjo4IpAlOF4dtzsXMkaJZN2e4TQF-7RfH7P9_VQsSaxYtTGrJMeG5DJBn5_nIU8kXKba9M43cNiCgAGEm9TuT2eO2VEWxkA/w669-h370/Haul30_day20_20220720_38kHz.png" width="669" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: helvetica;">Trek 30, 20 juli 2022 54.07N-1.58O, 1608kg sprot en 7kg wijting. - <i>Haul 30, 20 July 2022 54.07N-1.58E, 1608kg sprat and 7kg whiting.</i></span></b></td></tr></tbody></table><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgDr0yMFmqcSnU3Fh_NoBdQTY6wJHqrVySY_QLNImiXDnV0_tX_mvRx9ZfosgLUum5i3MiBXCT9R8CmUgc4WvS_jwkusgCcOHDB4MRqd_43lmg1wbxqDWp3H0DkXeijgMMM1YAJxoaLCObvuI_4IjLS6CBisSF7Ad-dpkq58r9vrstP_WrvQwwKPo1nWQ/s4032/20220720_122512.jpg" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" data-original-height="3024" data-original-width="4032" height="503" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgDr0yMFmqcSnU3Fh_NoBdQTY6wJHqrVySY_QLNImiXDnV0_tX_mvRx9ZfosgLUum5i3MiBXCT9R8CmUgc4WvS_jwkusgCcOHDB4MRqd_43lmg1wbxqDWp3H0DkXeijgMMM1YAJxoaLCObvuI_4IjLS6CBisSF7Ad-dpkq58r9vrstP_WrvQwwKPo1nWQ/w670-h503/20220720_122512.jpg" width="670" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: helvetica;">De vangst van trek 30 in de last. - <i>The catch of haul 30 in the hold.</i></span></b></td></tr></tbody></table><p><span style="font-family: helvetica;">Op dit stuk transect laten we meerdere keren de camera zakken. We zien deeltjes (soms bewegend), maar kunnen niet zien wat het is. Wanneer we de camera laten zakken op een laag op de bodem die alleen sterk tekent op de 18kHz, zien we zwemmende, langwerpige, doorzichtige organismen die af en toe heel kort zichtbaar zijn. Wat zijn het? Misschien pijlwormen (Chaetognaths)? Helaas slagen we er niet in om een goede foto of clip te maken, omdat de kwaliteit van de clips te laag en en de frame rate te hoog voor de software. Volgend jaar gaan we bekijken of de camera-opstelling kunnen verbeteren.</span></p><p><span style="font-family: helvetica;"><i>On this stretch of transect we lower the camera several times. We see particles (sometimes moving), but cannot see what they are. When we lower the camera to a layer on the bottom that only shows strongly on the 18kHz, we see swimming, elongated, transparent organisms that are occasionally visible for very short periods. What are they? Maybe arrow worms (Chaetognaths)? Unfortunately we are unable to take a good photo or clip because the quality of the clips is too low and the frame rate too high for the software. Next year we will see if we can improve the camera setup.</i></span></p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjzoCzw1AnWKEkN-X1TNwrNuwX1_r4tzheHP0VrkH4UvfWOyfYhvlvomstZznjOzxqMI-hYtyrjyTac8RO_CIQDjmOCjDl5cQBzab8RCAZgT-kO0otdlV5Odt6Oyq6O_2vmElotRaEFwD4bfd8_B9ZyG5AU87tXs-BfmBD_yc7X-ca7HjCALZNGCSCakw/s4032/20220720_141131.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="4032" data-original-width="3024" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjzoCzw1AnWKEkN-X1TNwrNuwX1_r4tzheHP0VrkH4UvfWOyfYhvlvomstZznjOzxqMI-hYtyrjyTac8RO_CIQDjmOCjDl5cQBzab8RCAZgT-kO0otdlV5Odt6Oyq6O_2vmElotRaEFwD4bfd8_B9ZyG5AU87tXs-BfmBD_yc7X-ca7HjCALZNGCSCakw/w480-h640/20220720_141131.jpg" width="480" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><b><span style="font-family: helvetica;">Beanne Snaar verzameld de otolieten van de sprot uit het snijmonster voor geslacht- en leeftijdsbepaling. - <i>Beanne Snaar collects the otoliths (ear stones) from the sprat sample for sex and age determination.</i></span></b></td></tr></tbody></table><span style="font-family: helvetica;">Na trek 30 blijft het echogram leeg, maar 27 nautische mijl voor het einde van het transect (en deze survey) worden we plotseling wakker geschut door twee enorme palen op het echogram.

Om 5:39 UTC op 54.48N-1.34E draaien we naar westzuidwest op een nieuw transect. Dit keerpunt ligt op het zuidoostelijke puntje van de Doggersbank en het is hier zo ondiep - ongeveer 25m - en de bodem is zo grillig, dat wij hier niet kunnen vissen. Dat geeft niet want er zijn toch geen visscholen te zien. Naar het westen toe wordt het weer dieper en om 9:48 zien we scholen (trek 28). Dit gebied ten zuidoosten van de Doggerbank staat bekend om de vele zwerfkeien. Daarom durven we niet dicht aan de grond te vissen met het pelagische net. De vangst is dan ook vrij klein: een mand gemengde vis (50% grauwe poon). We varen verder op het transect en draaien om 14:50 UTC, na CTD-opname 43 op 54.23N-0.13W naar ESE.</span></p><p><span style="font-family: helvetica;"><i>On Tuesday, July 19 at 4:10 UTC from 54.55N-1.17E, Tridens continues its east-southeast course. At 5:39 UTC at 54.48N-1.34E we will turn west-southwest on a new transect. This turning point is on the southeastern tip of the Dogger Bank and it is so shallow here - about 25m - and the bottom is so jagged that we cannot fish here. That does not matter because there are no schools of fish to be seen. To the west it gets deeper again and at 9:48 we see schools (draw 28). This area southeast of the Dogger Bank is known for the many boulders. That is why we do not dare to fish close to the ground with the pelagic net. The catch is therefore quite small: a basket of mixed fish (50% gray gurnard).

Boven een van de Devil's Holes, zetten we uit voor trek 20 op kleine rode schooltjes 5-10m boven de bodem. De vangst bestaat voornamelijk uit makreel, maar er zit ook wijting en kever in de vangst. Aangezien de echo's relatief sterker zijn op de lagere frequenties, gaan we er van uit dat ze toch afkomstig zijn van wijting en kever en dat de lichtere echo's op het scherm van de 38kHz afkomstig zijn van makreel. We voeren nog een trek (nr 21) uit op talrijke dieprode schooltjes op de bodem om 9:32 UTC. De vangst bestaat uit een paar vismanden wijting, maar er zit ook wat haring en kever in de vangst. </span><span style="font-family: helvetica;">Om 12:42 UTC bereiken we het einde van het transect en draaien naar het zuidwesten.

Vanaf dit punt varen we naar het westen op een nieuw transect.</span></p><p><span style="font-family: helvetica;"><i>The next morning on Wednesday, July 13, at 4:05 UTC, we resume the survey from 56.33N-0.22E to the east. Above one of the Devil's Holes, we shoot the net for haul 20 on small red shoals 5-10m above the bottom. The catch consists mainly of mackerel, but there is also whiting and Norway pout in the catch. Since the echoes are relatively stronger at the lower frequencies, we assume that they are nevertheless from whiting and Norway pout and that the lighter echoes on the 38kHz screen are from mackerel. We perform another haul (No. 21) on numerous scarlet shoals on the bottom at 9:32 UTC. The catch consists of a few fishing baskets of whiting, but there is also some herring and Norway pout in the catch.</i></span><i style="font-family: helvetica;"> At 12:42 UTC we reach the end of the transect and turn southwest.

Ook dit transect is betrekkelijk leeg. Om 8:31 UTC laten we de CTD met de camera zakken om te kijken op de bodem - we zagen namelijk wat echo's stijf op de grond - en zien enkele kevers zwemmen (56.25N-1.16W). Om 11:17 UTC verschijnen er toch wat kleine schooltjes, los van de grond. Hier vissen we op (trek 17). Tijdens de trek zien we hiervan niets terug op het echogram, maar er zit toch een halve vismand schelvis, sprot, wijting en grauwe poon in het net. Om12:13 UTC bereiken we het einde van het transect op 56.24N-0.32W en draaien richting NNW, naar het begin van het volgende transect op 56.33N-0.36W.

At 11:17 UTC some small schools appear, detached from the ground. This is where we fish (trawl 17). During the tow we do not see any of the echoes on the echogram, but nevertheless there is half a basket of haddock, sprat, whiting and gray gurnard in the net.

Tijdens de trek zien we niets van deze schooltjes terug op het echogram. De vangst bestaat uit twee doornhaaitjes. Doornhaaien leven op de grond en zijn niet zichtbaar met een echolood op deze diepte. We hebben dus geen aanwijzing om wat voor soort het gaat. We nemen ons verlies en beginnen terug te varen naar het punt waar we het transect hebben onderbroken voor deze trek. Dan zien we tot onze verbazing 3 scholen onder het schip verschijnen. We zetten uit voor trek 19 (18:26 UTC). Na lang wachten verschijn er eindelijk een school onder het schip. Helaas zien we maar heel weinig hiervan terug op het scherm van de netsonar. In de hoop dat er genoeg in het net zit om een indicatie te krijgen om welke soort het gaat, halen we het net. De vangst bestaat uit een vismand wijting, maar er zitten behalve doornhaaitjes ook 14 sprotjes en een haring bij. We nemen toch maar aan dat de echo's afkomstige zijn van wijting.</span><div><span style="font-family: helvetica;"><i>At 16:58 UTC we decide to go fishing for small schools (draw 18). During the haul we do not see any of these schools back on the echogram. The catch consists of two spurdogs. Spiny sharks live on the ground and are not visible with an echo sounder at this range. So we have no indication of what species the schools consist. We take our loss and begin to sail back to the point where we interrupted the transect for this haul. Then to our surprise we see three schools appear under the ship. We shoot the net for haul 19 (18:26 UTC). After a long wait, a school finally appears under the ship. Unfortunately, we see very little of this on the net sonar screen. In the hope that there is enough in the net to get an indication of which species it is, we haul the net. The catch consists of a fishing basket of whiting, but apart from spurdogs, there are also 14 sprats and a herring in it.

Er is weinig te zien op het echogram. Pas om 7:30 UTC zien we visscholen met daartussen een dunne laag. We zetten uit voor trek 13. De trek duur lang. Hoewel we voortdurend echo's zien op de trawlsonar - deze geeft een beeld van hetgeen in het net zwemt - zien we hiervan niets terug in op de sensors in de tunnel van het net. De echo's van de trawlsonar zijn dus kennelijk afkomstig van kleine vis die door de grote mazen van het net weer ontsnapt. We blijven net zo lang vissen tot we ook wat in de tunnel van het net zien. De bescheiden vangst bestaat uit enkele manden wijting en schelvis. Onze conclusie is dat de dunne laag bestaat uit kleine vis, waarschijnlijk kristalgrondel en jonge zandspiering, want in de mazen van het achternet en op dek treffen we deze soorten aan.</span></p><p><span style="font-family: helvetica;">On Friday, July 8, we launch at 3:01 UTC from 56.49N-0.56W to the east. There is little to see on the echogram. Only around 7:30 UTC do we see schools of fish with a thin layer in between. We shoot for haul 13. The haul is long. Although we continuously see echoes on the trawl sonar - this gives a picture of what is swimming in the net - we do not see any of this on the sensors in the tunnel of the net. The echoes from the trawl sonar apparently come from small fish escaping through the large meshes of the net. We keep fishing until we see something in the tunnel of the net. The modest catch consists of a few baskets of whiting and haddock. Our conclusion is that the thin layer consists of small fish, probably crystal goby and young sandeel, because we find these species in the meshes of the rear net and on deck.</span></p><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_7eEpHQ11ePCQfHRF3LERagoTEJCt-_Rg_M5RFXr5wpTlqyzhB4BVCAwSqpuurLiFxui4hVC_E17uIK49H3AVPu5aHeXIeFVsBS1JjZICcXqZixDOtA0rRQwYnyyQ9R0u8Mx7OlPnSTBZ2vGYikBwv3GKxiQC1BaZRKUHirLtXhx12RcqC8FKoZBLRA/s1564/Haul13_day10_20220708_38kHz.PNG" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" data-original-height="878" data-original-width="1564" height="373" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_7eEpHQ11ePCQfHRF3LERagoTEJCt-_Rg_M5RFXr5wpTlqyzhB4BVCAwSqpuurLiFxui4hVC_E17uIK49H3AVPu5aHeXIeFVsBS1JjZICcXqZixDOtA0rRQwYnyyQ9R0u8Mx7OlPnSTBZ2vGYikBwv3GKxiQC1BaZRKUHirLtXhx12RcqC8FKoZBLRA/w663-h373/Haul13_day10_20220708_38kHz.PNG" width="663" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: helvetica;">Trek 13, 8 juli 2022 56.49N-0.29E, 55kg wijting, 17 kg schelvis en 2 kg haring. - <i>Haul 13, 8 July 2022 56.49N-0.29E, 55kg whiting, 17 kg haddock en 2 kg herring.</i></span></b></td></tr></tbody></table><br /><p><br /></p><p><br /></p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgdbz6Dm66CA2KIIsjBTXB3ObGfIMex52xta-BpbKTtQb_C5qIBQC3ru23Kar5BH9bOOFat7Qeo8ApN_BfurWqD9VltSVffiZ4dNXq1Z0apgG5uPg3-lkoZzq2a6KrsS3Qzow6YfvuP7j17V2Sa_gBgEr-2lLsYWR6wzwW1dtDsedcnYm1CpiDhF6iCcA/s4032/20220708_120557.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="4032" data-original-width="3024" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgdbz6Dm66CA2KIIsjBTXB3ObGfIMex52xta-BpbKTtQb_C5qIBQC3ru23Kar5BH9bOOFat7Qeo8ApN_BfurWqD9VltSVffiZ4dNXq1Z0apgG5uPg3-lkoZzq2a6KrsS3Qzow6YfvuP7j17V2Sa_gBgEr-2lLsYWR6wzwW1dtDsedcnYm1CpiDhF6iCcA/w480-h640/20220708_120557.jpg" width="480" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><b><span style="font-family: helvetica;">Deel van de vangst van trek 13.

Bij trek 15 is er een laag te zien met rode schooltjes op de bodem. De vangst is een mix. Bij trek 16 vissen we op echo's hoog boven de bodem: dit levert een mengsel op van jonge kever en sprot.</span></div><div style="text-align: left;"><span style="font-family: helvetica;">Om 17:28 UTC komen we aan het einde van het transect (56.54N-2.05W) en draaien naar het zuiden.

At haul 15 there is a layer with red schools on the bottom. The catch is a mix.

Ondanks de lange trekduur, bestaat de vangst slechts uit een kwart vismand: jonge kever, wat sprot en enkeleschelvissen.

Despite the long tow duration, the catch consists of only a quarter of a fish basket: juvenile Norway pout, some sprat and a few haddock.

Meteen zien we veel schooltjes, maar we kunnen er niet op vissen vanweg de ruwe bodem. Wanneer de bodem bevisbaar wordt en er nog steeds scholen te zien zijn, slaat het noodlot toe: de brandstofpomp van een van de hoofdmotoren begeeft het. Dit betekent voor de rest van de survey dat vissen op moeilijke bodem niet meer verantwoord is en dat we bij dezelfde survey-snelheid (10 knopen) op een motor zullen moeten varen, hetgeen meer storing op het echogram veroorzaakt. Terwijl de machinisten en kapitein bellen met het thuisfront, varen we toch maar door. Op deze locatie zullen we het dus moeten doen zonder vangstinformatie van de echo's op de bodem.</span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: arial;"><i>On Monday morning, July 19, 2021, we begin the day by carrying out a CTD downcast at 4:00 UTC, 55.28.28N-1.21.74E, after which we will head west. Immediately we see many schools, but we cannot fish for them because of the rough bottom. When the bottom becomes fishable and schools can still be seen, disaster strikes: the fuel pump of one of the main engines fails. For the rest of the survey this means that fishing on difficult bottoms is no longer justified and that we will have to sail at the same survey speed (10 knots) on one engine, which causes more noise on the echogram. While the engineers and captain call the home front, we sail on anyway. At this location we will therefore have to do without catch information from the echoes on the bottom.</i></span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: arial;">Wanneer we dichtbij het westelijke uiteinde van het transect zijn, zien we een ander soort scholen: grote en kleine, iets boven de bodem. Daarnaast is er een laag zichtbaar op de 120 en 200kHz frekwenties. Van dit gebied weten we dat de bodem zacht is en we besluiten te vissen (14:09, trek 24). De vangst bestaat voor 90% uit sprot en voor 10% uit jonge haring van 16-20cm. Eindelijk weer haring en sprot!</span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: arial;"><i>When we get close to the western end of the transect, we see a different kind of schools: large and small, slightly above the bottom.

The bottom flattens out and some larger schools appear. We can fish for this (12:38 UTC, pull 22).

Om 9:01 UTC op 55.58.36N-2.14.60W draaien we vlak voor de de kust bij Saint Abbs Head, bij de zuidkant van de ingang van de Firth of Forth, naar het oosten. We bevinden ons ongeveer 20 zeemijl van Bass Rock, een rots met de grootste kolonie Jan van Genten ter wereld (ongeveer 150.000 broedparen). Dat is te merken, want overal om ons heen zijn Jan van Genten te zien. Ze zijn ook aan het het foerageren. Op het echogram zijn kleine scholen te zien in de waterkolom en bij het wateroppervlak. Het opvallende is dat deze scholen sterker tekenen op de hogere frekwenties (70, 120 en 200kHz) dan op de lagere frekwenties (18 en 38 kHz). Dit wijst er op dat dit geen haring, sprot of kabeljauwachtigen zijn, maar dat het gaat om een soort zonder zwemblaas: makreel of zandspiering. We nemen de proef op de som en zetten het net uit voor trek 20. Omdat het net niet goed staat op de netsonar - mogelijk doordat er iets is mis gegaan bij het uitzetten - halen we na korte korte tijd en zetten opnieuw uit (trek 21).</span></p><p><span style="font-family: arial;"><i>On Saturday morning 4:02 UTC we take off at 56.20.47N-0.57.84W heading southwest. At 9:01 UTC at 55.58.36N-2.14.60W we turn east just off the coast at Saint Abbs Head, at the south end of the entrance to the Firth of Forth. We are about 20 nautical miles from Bass Rock, a rock with the largest gannet colony in the world (about 150,000 breeding pairs). This is noticeable, because Jan van Genten can be seen all around us. They are also foraging. The echogram shows small schools in the water column and near the water surface. The striking thing is that these schools show more strongly on the higher frequencies (70, 120 and 200 kHz) than on the lower frequencies (18 and 38 kHz). This indicates that these are not herring, sprat or cod-like species, but that they are a species without a swim bladder: mackerel or sand eel. We decide to check this and shoot the net for haul 20. Because the net is not in the right position on the net sonar - possibly because something went wrong during shooting - we take it out after a short short time and set it again (haul 21 ).</i></span></p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiWOF_aH4bqKu6PzLOxM9Eg0rGggTLuVj7F7RS-0V8HvDds-wkGlaPae8C-aZGdGIpPXZoM_hCVhnQJtDggv6B_1PhNqOeseTbkAjNRNbEbO_7pzJa06Zu-BVg0p1WgYkrpU8Jl9m341Xqh/s1558/Haul+20+17072021+0929_38kHz.bmp" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="941" data-original-width="1558" height="386" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiWOF_aH4bqKu6PzLOxM9Eg0rGggTLuVj7F7RS-0V8HvDds-wkGlaPae8C-aZGdGIpPXZoM_hCVhnQJtDggv6B_1PhNqOeseTbkAjNRNbEbO_7pzJa06Zu-BVg0p1WgYkrpU8Jl9m341Xqh/w640-h386/Haul+20+17072021+0929_38kHz.bmp" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: arial;">Trek 20 en 21, 17 juli 2021, 55.58.04N-2.06.00W, 29kg kwallen en wat jonge vis: schelvis, sprot, haring, wijting en zandspiering, en enkele makrelen.

Het lukt niet om de calibratie-bol onder het schip te krijgen doordat de draden ergens onder de waterspiegel, op de scheepsromp vastlopen.

Doordat er een lichte stroming staat, lukt het ook niet om de lijnen weg te houden van het deel van de romp waarvan we weten dat er zinkanoden zitten.</span></p><p><i style="font-family: arial;">This calibration is not going according to plan. It is not possible to get the calibration sphere under the ship because the wires get stuck on the ship's hull somewhere below the water surface. The wires may get caught behind a zinc anode mounted on the hull: when this sacrificial metal corrodes according to plan (to prevent the hull from rusting away), a gap naturally forms into which lines can catch. Because there is a light current, it is also not possible to keep the lines away from the part of the hull where we know that there are zinc anodes.</i></p></div><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj6-VDFemx5ZJy1GXevAUWSCiovEKP7iikCIyBzO2FJCfDffZBSVOSob9_vainYiHt_JbF9OfWDa7apYBCeIs4kdLlyg3OmINtOmMSYiPumjtoXcOavnBBhG3gxPgvFkQmQhSPh8HBkLFqg/s2048/20210715_172422.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1536" data-original-width="2048" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj6-VDFemx5ZJy1GXevAUWSCiovEKP7iikCIyBzO2FJCfDffZBSVOSob9_vainYiHt_JbF9OfWDa7apYBCeIs4kdLlyg3OmINtOmMSYiPumjtoXcOavnBBhG3gxPgvFkQmQhSPh8HBkLFqg/w640-h480/20210715_172422.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: arial;">Voor het calibreren gaat de Tridens met toestemming van de plaatselijke authoriteiten, voor anker net buiten het officiele ankergebied voor Aberdeen.

Tijdens CTD opname nummer 23, verschijnt er een laag rode schooltjes op de bodem. We vissen hierop om 9:12 UTC tijdens trek 16. Zou de vangst weer uit schelvis bestaan of is het dit keer misschien haring?

Op vrijdagochtend 9 juli vertrekt iedereen naar huis. Bram doet dit op de fiets, door de duinen. Wanneer hij door Meijendel fietst (tussen Scheveningen en Katwijk), ziet hij meerdere julikevers (<i>Polyphylla fullo</i>). De julikever is nauw verwand aan de meikever. De soort leeft als engerling 4 jaar onder de grond waar hij leeft van de wortels van dennebomen en komt, nadat hij zich heeft verpopt, voor enkele dagen boven de grond om te paren. De soort is niet erg algemeen in Nederland en je moet maar net geluk hebben dat je ze tegenkomt wanneer ze tevoorschijn komen. Wanneer je ze vastpakt, maken ze een knerpend geluid. De mannetjes hebben grote, schoenlepelvormige, antennes.</span></p><p><span style="font-family: arial;"><i>From Thursday evening 8 July to Monday morning 12 July (11:30 UTC) the Tridens is lying on the quay in the harbour of Scheveningen. Everyone leaves for home on Friday morning 9 July. Bram does this by bike, through the dunes. When he cycles through Meijendel (between Scheveningen and Katwijk), he sees several pine chafer beetles (</i>Polyphylla fullo<i>). The July beetle is closely related to the cockchafer. The species lives underground for 4 years as grub, feeding on the foliage of pine trees and after it has pupated, comes above the ground for a few days to mate. The species is not very common in the Netherlands and you have to be lucky to come across them when they emerge. When you pick them up, they make a crunching sound. The males have large, shoehorn-shaped antennae.</i></span></p><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCLWZZZLnilSc7s5X3DfsxwRnyOHPGfIjlgSZBb41UdAmqxXgy6IsYnUuhr-QD-BQkX_jul0RbqOGsFk1XGABj7UjTdCOcQBGEjtE8JMGKPeRP5pgGuUzOWx16Fw54PS0-EadgPH11-Hqs/s2048/20210709_082539.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1536" data-original-width="2048" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCLWZZZLnilSc7s5X3DfsxwRnyOHPGfIjlgSZBb41UdAmqxXgy6IsYnUuhr-QD-BQkX_jul0RbqOGsFk1XGABj7UjTdCOcQBGEjtE8JMGKPeRP5pgGuUzOWx16Fw54PS0-EadgPH11-Hqs/w640-h480/20210709_082539.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: arial;">Julikever (<i>Polyphylla fullo</i>), mannetje - <i>Pine chafer (</i>Polyphylla fullo<i>), male</i></span></b></td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiz9ndEmkA8Ht3WrcBrCgGs1n8rUsS-V7z6Td30AExdmwMrXIf0urZz100ns0hFpSG2MMrQdtE2pzD7lfzWlH2w_ripaPbOnBQoil-XOmQO3p8cHJ8Vp8DDArG6STutr7VpIx1NEtSXIE1E/s2048/20210709_083820.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1536" data-original-width="2048" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiz9ndEmkA8Ht3WrcBrCgGs1n8rUsS-V7z6Td30AExdmwMrXIf0urZz100ns0hFpSG2MMrQdtE2pzD7lfzWlH2w_ripaPbOnBQoil-XOmQO3p8cHJ8Vp8DDArG6STutr7VpIx1NEtSXIE1E/w640-h480/20210709_083820.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: arial;">Julikever, vrouwtje - <i>Pine chafer beetle, female</i></span></b></td></tr></tbody></table><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen='allowfullscreen' webkitallowfullscreen='webkitallowfullscreen' mozallowfullscreen='mozallowfullscreen' width='320' height='266' src='https://www.blogger.com/video.g?token=AD6v5dz_RME0SkSGOGNDgvTIgGVKDpgVffuvxrvHzQNunzdfVVGGIu2zTRhy5i_EVmHSHnieVLdzcyip-YkPMUGYvw' class='b-hbp-video b-uploaded' frameborder='0'></iframe></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div><br /><p><br /></p>herringsurveyhttp://www.blogger.com/profile/00544276166728311463noreply@blogger.com0tag:blogger.com,1999:blog-3822497927606356569.post-5627070217897314492021-07-08T22:16:00.003+02:002021-07-17T10:28:17.184+02:00Rubberboot - Dinghy<p><span style="font-family: arial;">Op woensdag 7 juli varen we om 3:02 UTC vanaf 57.13N-0.09W verder richting het westen. We draaien om 7:13 UTC op 57.13N-1.22W naar zuidoost, het intertransect op en om 8:28 op 56.58N-1.05W naar het oosten, op het nieuwe transect. Om 11:21 UTC vissen we op grote, pelagische scholen. Dat zal toch zeker wel haring zijn? Afgaande op het beeld van de netsonde (dat is de sonar in de trawlopening) lukt het niet om één van de scholen te vangen. De vangst bestaat uiteindelijk uit 700kg schelvis en wijting. Er zit één haring in de vangst. We twijfelen nu of dit echt wel haringsscholen waren en herinneren ons dat we vorig jaar soortgelijke scholen en vangsten hadden (zie de blog van 2020). Aangezien we voor 22:00 UTC aan het einde van dit transect willen zijn om op tijd naar Scheveningen te varen voor de mid-survey-onderbreking, hebben we geen tijd om een extra vistrek te doen. We nemen ons voor om na dit na het weekend in te halen op het volgende transect (56.43N). Om 21:00 UTC bereiken we het einde van het transect (56.58N-2.00E) en zetten koers naar Scheveningen.</span></p><p><span style="font-family: arial;"><i>On Wednesday, July 7, we will sail further west at 3:02 UTC from 57.13N-0.09W. We turn southeast at 7:13 UTC at 57.13N-1.22W onto the intertransect and east at 8:28 at 56.58N-1.05W onto the new transect. At 11:21 UTC we fish for large, pelagic schools. Surely that must be herring? Judging by the image of the net sonar (that is the sonar in the trawl opening) we fail to catch one of the schools. In the end the catch consists of 700kg haddock and whiting. There is one single herring in the catch. We now start to doubt whether these were really herring schools and remember that we had similar schools and catches last year (see the 2020 blog). Since we want to be at the end of this transect before 22:00 UTC to sail to Scheveningen in time for the mid-survey break, we don't have time to do an extra tow.
