De wind is dan afgenomen to 6 E. In de ochtend zien we aan stuurboord een eiland. Dat is St. Kilda. Om 7:58 UTC op 57.56.32N-9.00.06W draaien we naar het westen op het volgende transect. In het begin zijn we nog op het continentale plat. Gewoonlijk beginnen we blauwe wijting te zien als de diepte 400m wordt. Deze echo's vormen naar westen toe de welbekende laag blauwe wijting op ongeveer 450m diepte. Nu zien we scholen op 240m diepte die steeds talrijker worden en een laag op de bodem beginnen te vormen. We zijn er niet zeker van of dit blauwe wijting is en zetten om 9:16 UTC het net uit voor trek 9. De vangst bestaat uit vrij kleine blauwe wijting.</span></p><p><span style="font-family: arial;"><i>On the night of Wednesday 27 - Thursday 28 March, we turn north at 0:41 UTC at 56.34.91N-9.00.23W. The wind has then decreased to 6 E. In the morning we see an island at starboard. That is the isle of St. Kilda. At 7:58 UTC at 57.56.32N-9.00.06W we turn west on the next transect. In the beginning we are still on the continental shelf. Usually we start seeing blue whiting when the depth reaches 400m. To the west, these echoes form the well-known layer of blue whiting at approximately 450m depth. Now we see schools at 240m depth that are becoming more numerous and starting to form a layer on the bottom. We are not sure if this is blue whiting and shoot the net at 9:16 UTC for haul 9. The catch consists of quite small blue whiting.</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/AVvXsEiOVmQWbTKVgeQ08Mu85OhsEGf8WxUU0ws5gNbZiVnxDEZxsfNcUQkXk-4mmI0otU38rCHT8aGVQ-CeSWBi1krSx_gK2gn00fg20gSoXPVPxiMgENOGZWiDEaik00zbsgi4XO0UAy9TY7bgOTGGUsL1KjIHN_tajn9AAwI9ZB2YtQTLJ8wa7BBKL7bePpA/s1973/WhatsApp%20Image%202024-03-28%20at%2010.00.56_f85182d9.jpg" imageanchor="1" style="margin-left: auto;

We blijven veel blauwe wijting zien op het echogram, maar vissen er vandaag nier meer op. Door het slecht weer van de afgelopen anderhalve week, zijn we fors achterop het schema geraakt. Helaas komt er nog meer slecht weer aan. Om18:24 UTC als we stoppen voor een CTD-opname, is de wind alweer aangewakkerd tot ONO 8. Na het CTD-station hebben we nog 10 mijl de wind van achteren.

We continue to see a lot of blue whiting on the echosounder, but we are no longer fishing for them today. Due to the bad weather of the past week and a half, we have fallen well behind schedule. Unfortunately, more bad weather is coming. At 18:24 UTC when we stop for a CTD recording, the wind has already increased to ENE 8. After the CTD station we still have the wind behind us for ten more miles. As we turn north at 57.56.08N-11.59.85, 20:03 UTC, our speed drops to 4-5 knots.</span></p>Blue Whiting Surveyhttp://www.blogger.com/profile/05152086739508805004noreply@blogger.com0tag:blogger.com,1999:blog-8384813579987492813.post-970256649791628962024-03-27T18:07:00.001+00:002024-03-27T18:18:34.190+00:00Gedwongen afkorting - Forced shortcut<p><span style="font-family: arial;">Op dinsdag 22 maart voeren we een CTD-opname uit om 6:45 UTC op 55.20.43N-14.11.74W. Op deze locatie besluiten we om het transect naar het westen in de richting van Rockall Bank af te breken en een noordoostelijke koers te varen naar 56.34.25N-12.01.40W naar het volgende transect ten noorden van ons. De reden is dat we als gevolg van het slechte weer tijdens de afgelopen week, veel vertraging hebben opgelopen. De beslissing is moeilijk, want we zien nog steeds blauwe wijting, hoewel het wel veel minder is dan in het oosten. Wat ook meespeelt bij onze beslissing is dat er weer storm aan komt, dit keer uit het oosten, terwijl de hoogste windsnelheden vooral in het westen, boven Rockall Bank worden voorspeld. Door zo snel als mogelijk naar het oosten te gaan, hopen we de ergste wind zoveel mogelijk te ontlopen en ook minder last te krijgen van de oceaandeining: omdat de wind uit het oosten komt, stuwt de deining minder hoog op door de ligging van Ierland. We hopen door deze beslissing te voorkomen dat we langer dan nodig vast komen te liggen, zodat we later in het noorden meer transect kunnen varen.</span></p><p><i style="font-family: arial;">On Tuesday, March 22, we carry out a CTD downcast at 6:45 UTC at 55.20.43N-14.11.74W. At this location we decide to break the transect to the west towards Rockall Bank and sail a northeasterly course to 56.34.25N-12.01.40W to the next transect north of us. The reason is that we have been delayed a lot due to the bad weather during the past week. The decision is difficult because we are still seeing blue whiting, although much less than in the east. What also plays a role in our decision is that another storm is coming, this time from the east, while the highest wind speeds are mainly predicted in the west, above Rockall Bank. By moving east as quickly as possible, we hope to avoid the worst wind as much as possible and also be less affected by the ocean swell: because the wind comes from the east, the swell does not rise as high due to Ireland's location.

In de loop van de ochtend neemt de wind iets af en varen we langzaam naar het noorden, naar het beginpunt van het volgende transect (53.41.07N-16.00.00). Om 13.13 UTC draaien we naar het oosten.

Het gebied is groot, daarom doen we dit onderzoek met vijf schepen van verschillende landen tegelijk. De blauwe wijting kan zich snel verplaatsen. Om ervoor te zorgen dat we de vis niet mislopen of dubbel tellen, moeten we met alle schepen tegelijk zo snel mogelijk in een richting het gebied bestrijken. Op het kaartje kun je zien hoe onze planning eruit ziet. Het Spaanse schip, de Vizconde de Eza, was al eerder in het gebied en heeft inmiddels het zuidelijke deel gedaan (blauwe transecten). De Tridens (oranje transecten) heeft 6 transecten in het zuiden bijna af en het Ierse schip, de Celtic Explorer (groene transecten), heeft in hetzelfde gebied ook 2 transecten gedaan. De Celtic Explorer heeft de afgelopen twee dagen geschuild in een baai langs de Ierse kust en gaat morgenochtend beginnen aan het groene zigzag-transect. Het Noorse schip, de Vendla is de afgelopen dagen in de storm vanuit Noorwegen hierheen gevaren en gaat morgenochtend vroeg beginnen aan het het rode transect. Het Faroese schip, de Jakup Sverri, vertrekt vannacht uit Thorshavn in de richting van het gebied om te beginnen aan het gele transect. Hoewel alle schepen wat vertraging hebben opgelopen door de storm, lopen we nog wel mooi synchroon met elkaar.</span></p><p><span style="font-family: arial;"><i>The aim of this research is to provide a stock estimate of the blue whiting that come to Porcupine Bank, Rockall Bank and the edge of the continental shelf to spawn around this time. The area is large, which is why we are conducting this research with five ships from different countries at the same time. The blue whiting can move quickly. To ensure that we do not miss or double count the fish, we must cover the area with all ships simultaneously in one direction as quickly as possible. On the map you can see what our planning looks like. The Spanish ship, the Vizconde de Eza, had already been in the area before and has now completed the southern part (blue transects). The Tridens (orange transects) has 6 transects almost completed in the south and the Irish ship, the Celtic Explorer (green transects), has also completed 2 transects in the same area. The Celtic Explorer has been sheltering in a bay along the Irish coast for the past two days and will start the green zigzag transect tomorrow morning. The Norwegian ship, the Vendla, has sailed here from Norway during the storm in recent days and will start the red transect early tomorrow morning. The Faroese ship, the Jakup Sverri, will leave Thorshavn tonight towards the area to start the yellow transect. Although all ships have been slightly delayed by the storm, we are still in good sync with each other.</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/AVvXsEh2pF06l3N4ou95WQhx-2FcxoZTKPZhrQbML1wGgWeG0BbOzRuQw2HVprfoOJRqYNr-LyGneqANxFizCscLLfu8aFkOTFfqzULRuR04qhLwBUCp5vyFf0QQaNA5i9Z4fOY0UeTSZZw1G3g_Yay4IFFH5Yy5c24GebKoc_TVDrEBK7c5VieZtvaMDDIdzNg/s2700/Course%20track%20IBWSS%202024.png" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="2700" data-original-width="2236" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2pF06l3N4ou95WQhx-2FcxoZTKPZhrQbML1wGgWeG0BbOzRuQw2HVprfoOJRqYNr-LyGneqANxFizCscLLfu8aFkOTFfqzULRuR04qhLwBUCp5vyFf0QQaNA5i9Z4fOY0UeTSZZw1G3g_Yay4IFFH5Yy5c24GebKoc_TVDrEBK7c5VieZtvaMDDIdzNg/w530-h640/Course%20track%20IBWSS%202024.png" width="530" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><b><span style="font-family: arial; font-size: medium;">Geplande transecten van de onderzoeksvaartuigen die deelnemen aan dit onderzoek. - <i>Planned transects of the research vessels participating in this study.

Op 450m diepte zien we alleen zwakke echo's. De blauwe wijting laag bevindt zich hier op ongeveer 600m diepte. We zetten uit voor trek 12 om 5:50 UTC. In de blauwe wijting vangst zit ook grote zilversmelt en heek. Dit zijn twee soorten die we nog niet veel in de vangst hebben gehad tijdens de reis van dit jaar. Een verklaring hiervoor is dat er vrij veel blauwe wijting in het gebied zit. Hierdoor zit er langs de rand van het continentale plat meestal veel blauwe wijting hoog in de waterkolom en kunnen we een monster vangen, zonder dat we dicht bij de bodem komen. Om die reden zijn soorten die vlak boven de bodem leven, zoals grote zilversmelt en heek, minder sterk vertegenwoordigd in de vangst. In dit geval hebben we wel vrij dicht boven de bodem gevist.</span></p><p><span style="font-family: arial;"><i>The next morning, Monday 3 April 2023, we sail a section of the Irish 59.21N transect, from the shallows above the continental shelf in a westerly direction to the deep waters of the ocean. At 450m depth we only see weak echoes. The blue whiting layer is located here at about 600m depth. We shoot for haul 12 at 5:50 UTC. The blue whiting catch also contains large silver smelt and hake. These are two species we haven't had much in catch on this year's trip. An explanation for this is that there is quite a lot of blue whiting in the area. As a result, there is usually a lot of blue whiting high in the water column along the edge of the continental shelf and we can catch a sample without getting close to the bottom. For this reason, species that live close to the bottom, such as large silver smelt and hake, are less strongly represented in the catch.

At 22:21 UTC we do a CTD downcast (No. 19) at 56.47N-12.00W and begin a new transect heading west.</i></span></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/AVvXsEiXxvNJiHBZmw7giZE7Lm5X9cvXMmgI8ArR0MbLsvZoKN_v32lTIRrsRxWwc6qYIVO0EYvD_yOm7v1vhmz3ew6aam8RdGtIF6ujscMtgxcM3eHcfwW1RZ1vAV3q35KbwrlcMz4piLR4r3NDBrWZqAkAWIA_SMjT4m414W_JRJqllk0kUYB2dDzPGb8e/s1344/DSC02025.jpg" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" data-original-height="896" data-original-width="1344" height="442" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiXxvNJiHBZmw7giZE7Lm5X9cvXMmgI8ArR0MbLsvZoKN_v32lTIRrsRxWwc6qYIVO0EYvD_yOm7v1vhmz3ew6aam8RdGtIF6ujscMtgxcM3eHcfwW1RZ1vAV3q35KbwrlcMz4piLR4r3NDBrWZqAkAWIA_SMjT4m414W_JRJqllk0kUYB2dDzPGb8e/w664-h442/DSC02025.jpg" width="664" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><p class="MsoNormal" style="text-align: left;"><span style="line-height: 20px;"><b><span style="font-family: arial; font-size: x-small;"><i>Phronima</i> sp.

Bank. In de schemering is op 380m een dunne laag boven de bodem zichtbaar. Bij
het uitzetten voor trek 11 – bij daglicht – wordt de laag nog dunner. Vorig
jaar op ongeveer dezelfde locatie hebben we op een dergelijke laag gevist, maar
dan op 200m. De vangst was toen grauwe poon. Dit keer bestaat de vangst uit een
halve maand kroeyers lantaarnvis, wat zilversmelt en zilverkabeljauwtjes. Om 11:11

At twilight a thin layer is visible above the bottom at 380m. When shooting the net for haul 11 – in daylight – the layer becomes even thinner. Last year at about the same location we fished on a similar layer, but at 200m. The catch was grey gurnard. This time the catch consists of half a month of Kroeyer's lantern fish, some silver smelt and silvery pout. At 11:11 we do a miknet tow (no.16) at a depth of 30m.

een dun laagje op de bodem. Het is lastig om hierop te vissen met een pelagisch
net, omdat de bodem rotsachtig is. Om te voorkomen dat het net kapot scheurt,
vissen we niet te dicht op de bodem, waardoor bijna alle vis onder de onderpees
ontsnapt. Niettemin zit er genoeg vis in de kuil voor een aanwijzing om welke soort
het gaat: schelvis.</span></div><div style="text-align: left;"><i style="font-family: arial;">On the Rockall Bank,
where the depth is about 180m, we see a thin layer on the bottom. It is
difficult to fish with a pelagic net because the bottom is rocky. To prevent the

Voor ons is dat ongeveer de locatie van trek 11 aan de oostkant van Rockall Bank. We hebben die 60 mijl bijna bereikt en staan op het punt om naar het noorden te varen, wanneer er op de glooiende westrand van de Bank een laag zichtbaar wordt op het echogram. Het lijkt verdacht veel op blauwe wijting en we besluiten daarom om er op te vissen (trek 13: 18:41 UTC). De vangst bestaat inderdaad uit blauwe wijting. Er zitten ook zilverkabeljauwtjes doorheen.

For us, that's roughly the location of haul 11 on the east side of Rockall Bank. We have nearly reached those 60 miles and are about to head north when a layer appears on the echogram on the sloping western edge of the Bank. It looks suspiciously like blue whiting so we decide to fish for it (haul 13:18:41 UTC). The catch is indeed blue whiting. There are also silvery pout in it.

Dit levert ons het laatste monster blauwe wijting op van deze reis.</span></div><div style="text-align: left;"><span style="font-family: arial;"><span style="text-align: center;"><div style="text-align: left;">At 16:33 UTC at 57.48N-15.47W we turn east on the new transect. In the evening at 19:58 UTC at 57.58N-14.43W we do the last mik net tow of this research trip (no. 20 at 20m). On Friday morning, April 1, at 6:25 UTC, we reach the end of this transect (57.58N-12.00W), turning north and beginning at 10:14 UTC at 58.47N-12.00W at the last transect eastbound, to the edge of the continental shelf. The echogram remains blank until a huge school appears in the evening at 19:33 UTC. We pick it up with the sonar and manage to catch some of it. This gives us the last sample of blue whiting of this trip.</div></span></span></div><div style="text-align: left;"><span style="font-family: arial;"><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/AVvXsEjIaxvlDbrf8RUnNbVvdspW2rQrwlRx5aTjIRLSu72tzKvElmh4EEL1YBt_5Qu0HM3pvzWVfe32HG3EmNcWaNqLtxFNAiU0UNH1Pd6uTeRCvWPGbh2tf5N3vi40wUBsWh2E5SFPZHjI0RJLrN03GcBZPvRujy8xLcNCkQLEIrIodENAtkfdIzbYsN6A/s1441/20220401_haul14.PNG" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" data-original-height="900" data-original-width="1441" height="415" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIaxvlDbrf8RUnNbVvdspW2rQrwlRx5aTjIRLSu72tzKvElmh4EEL1YBt_5Qu0HM3pvzWVfe32HG3EmNcWaNqLtxFNAiU0UNH1Pd6uTeRCvWPGbh2tf5N3vi40wUBsWh2E5SFPZHjI0RJLrN03GcBZPvRujy8xLcNCkQLEIrIodENAtkfdIzbYsN6A/w665-h415/20220401_haul14.PNG" width="665" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-size: x-small;">Trek 14, 31 maart <span lang="EN-GB" style="line-height: 125%;">58.48N-9.11W, </span>12 ton blauwe wijting.

During this stretch between two transects, the crew does two exercises. First, a Williams turn is executed. This is the maneuver in case of a man overboard. Then a crash stop (emergency stop) is practiced. A crash stop is performed when an obstacle suddenly appears in front of the ship and there is no way to avoid it. At 16:37 UTC at 55.19N-13.36W we will begin the new transect heading east.<br /></i></span><br /><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/AVvXsEie6EzLnVox1JnNz-31mcqk6cUZxwxqXWW2IWAFSnYOyJ-paVPMd4KpJB2EQ0cWmPpF8MGEkFjnLakceb1MF4ikWmpu3yijob222Fan1vLDJjF-iuUy45dGp96Bej6mFN48tMret_hYeLuhjVtWaO63pZbkADzTntchuPiSaPHP-_39tAHOXoVNARYH/s1344/20220327_113416.jpg" imageanchor="1" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1008" data-original-width="1344" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEie6EzLnVox1JnNz-31mcqk6cUZxwxqXWW2IWAFSnYOyJ-paVPMd4KpJB2EQ0cWmPpF8MGEkFjnLakceb1MF4ikWmpu3yijob222Fan1vLDJjF-iuUy45dGp96Bej6mFN48tMret_hYeLuhjVtWaO63pZbkADzTntchuPiSaPHP-_39tAHOXoVNARYH/w640-h480/20220327_113416.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: arial; font-size: x-small;">Riekelt in actie op de brug tijdens het oefenen van de "Williams turn" en de crash stop. - <i>Riekelt Hakvoort in action during the drills of the "Williams turn" and the crash stop.</i></span></b></td></tr></tbody></table><b><span style="font-family: arial; font-size: x-small;"><br /></span></b><div class="separator" style="clear: both; text-align: left;"><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/AVvXsEjGtNdDZIU8beFw1uQUbih2L9JCnel7TocFgSy_JJaY1y4FnT1C2t6nWkdwUEQkvmmhtVg80J02h0xpDgD2p32vqEx9L7S3JkG2HwOCvnK-RoTfezRHJOKa6OipF975dgnisllb0Hamp9iEUAAx5ssIAhFf5TrtMrxe3YD5Px1rq1HFyXJr-l3-q4vO/s1343/_DSC0669gannet.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto; text-align: center;"><img border="0" data-original-height="817" data-original-width="1343" height="390" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjGtNdDZIU8beFw1uQUbih2L9JCnel7TocFgSy_JJaY1y4FnT1C2t6nWkdwUEQkvmmhtVg80J02h0xpDgD2p32vqEx9L7S3JkG2HwOCvnK-RoTfezRHJOKa6OipF975dgnisllb0Hamp9iEUAAx5ssIAhFf5TrtMrxe3YD5Px1rq1HFyXJr-l3-q4vO/w640-h390/_DSC0669gannet.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: arial; font-size: x-small;">Jan van Gent (Morus bassanus).

The ice lantern fish are missing in this haul.</i></span><br /><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/AVvXsEip6YthNnevnGcDc9lRPgGa8z6-iNhoghwxCEzBtNPor8hPDz2x_5IIyf1ImaOsqDdNn0eA31bbsw2K0pVisb6c8AlXSYYxrNagmzHshAeRM-8MpdOZFJQuZaTnUZSDrIHtMR7pwGiEk2bAswHHOdpcz8DI8mjXdH-rDPDScbw8a5E6mvxptNj_7N9M/s1434/DSC01280.jpg" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" data-original-height="956" data-original-width="1434" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEip6YthNnevnGcDc9lRPgGa8z6-iNhoghwxCEzBtNPor8hPDz2x_5IIyf1ImaOsqDdNn0eA31bbsw2K0pVisb6c8AlXSYYxrNagmzHshAeRM-8MpdOZFJQuZaTnUZSDrIHtMR7pwGiEk2bAswHHOdpcz8DI8mjXdH-rDPDScbw8a5E6mvxptNj_7N9M/w640-h426/DSC01280.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: arial; font-size: x-small;">Juveniele zeesterren in de vangst van miknet-trek 2. - <i>Juvenile starfish in the catch of miknet trek 2.</i></span></b></td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9lFBGlRjSi-1wHnZBcKhppeXFsqjbWVjVbWGjLdG1ZR5XmgVfTtjH2CPxnCLbBB_D_IRIoNulFaXWL6F5r2V4ryU1rQ3qN8FkxlJyl36qhRXuam6mdyQL_h0n2cLmZMoKu_LGL6wtpeXvPilafKasYSk6PeEb27YrpZOafktPE3pQ_zTXeZTsp18H/s1434/DSC01270.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="956" data-original-width="1434" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9lFBGlRjSi-1wHnZBcKhppeXFsqjbWVjVbWGjLdG1ZR5XmgVfTtjH2CPxnCLbBB_D_IRIoNulFaXWL6F5r2V4ryU1rQ3qN8FkxlJyl36qhRXuam6mdyQL_h0n2cLmZMoKu_LGL6wtpeXvPilafKasYSk6PeEb27YrpZOafktPE3pQ_zTXeZTsp18H/w640-h426/DSC01270.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><b><span style="font-family: arial; font-size: x-small;">Een zeevlinder (<i>Driacria trispinosa</i>) - <i>A sea butterfly </i>(Diacria trispinosa)</span></b></td></tr></tbody></table><br /><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgNWamHOLoLNAibaRsuKPgk_r6fHa8aEzyObCZrKypNACP2fHNgcIsrjnLg1YzsoPkYHfRii8ThzynWeRkHmkgbbq6AVGi_P6DwVVRky4Mg8_Y_uAIaPKUJLLDnl8xqdPvHai6alb8XX-wa12zlc07Wm2Z2-52kfl7hEqkT3fT0qWGpYo97XO8G0CDM/s1434/DSC01265.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="956" data-original-width="1434" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgNWamHOLoLNAibaRsuKPgk_r6fHa8aEzyObCZrKypNACP2fHNgcIsrjnLg1YzsoPkYHfRii8ThzynWeRkHmkgbbq6AVGi_P6DwVVRky4Mg8_Y_uAIaPKUJLLDnl8xqdPvHai6alb8XX-wa12zlc07Wm2Z2-52kfl7hEqkT3fT0qWGpYo97XO8G0CDM/w640-h426/DSC01265.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: left;"><span style="font-family: arial; font-size: x-small;"><b>Miknet trek 2: lichtende kwallen (Pelagia noctulica) - <i>Mik net 2: pink mauver jelly fish (Pelagia noctulica)</i></b></span></td></tr></tbody></table><br /><br /><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: arial;">Na miknet trek 2, varen we verder naar het westen, buigen om 18:14 UTC 51.10N-16.00W naar het noorden in de richting van het volgende transect dat begint op 51.28N-15.59W.
