The first few grabs of the day brought up coarse sandy sediment, with some cobbles. This sediment had fewer worms than seemed to be present in the mud that we sieved at the cSAC survey sites, instead containing sand eels, burrowing urchins and brittlestars that live in the sediment. As the sediment was coarse it collected more readily in the 1mm sieves, extending the sieving time per sample. By lunch time a number of grabs had been taken but there was plenty left to go!
Some images of the species we found in the grab samples. Top left: spider crab, disguised with marine life growing on its shell. Top right: Purple heart urchin (Spatangus purpureus). Bottom: Sandeel, a key food source for seabirds in the North Sea.
