Fortunately the weather is great! The sun emphasizes the plankton bloom and gives the sea a greenish Caribbean color.

Fortunately the weather is great! The sun emphasizes the plankton bloom and gives the sea a greenish Caribbean color. From a satelite you can see these patches as pale blotches a midst dark blue. The satellite picture is from 11 June, meaning that the location of the bloom is different from the current situation.

We are now on the 58.04N transect and once more fore herring (Haul 3). The herring is relatively large, up to 30 cm. The gonads indicate that they are mature and that they are developing. Hendrik is very skilled in taking the otoliths: little bones in the head. We collect the otoliths to read the age of the herring. If you look at an otolith under a microscope you can see grow rings, like the ring of a tree.

Dirk is preparing the new maatjes we caught on our way towards Scapa Flow. To be honest they are not as good as we are used to on board Tridens.

On saturday the 2 th of July we are deep in the the Moray Firth. There is not much fish and no need to fish. As a result we can stop for the weekend earlier than expected. at 12:30 we enter the port of Aberdeen. The weather is excellent and it will stay like on sunday as well. Groups of Red-breasted Mergansers swim in the harbour.
