Another successful MAREANO cruise finished

Cruise diary: MAREANO's last biology-geology-pollution mapping cruise this season is finished, and once more we have had good weather in the Barents Sea. Thus, we have finished all cruise activities that were planned for this year, in addition to making a small start on next year's tasks.

The Finnmark coast was, as we expected, quite variable – both regarding geology and biology. We had stations from near the shore (the shallowest station was in around 50 m water depth) out to around 50 km from the coast. Along Finnmark, we have covered 7500 km2 during the two cruises in 2014 – in April and now in August.

Our stations in the southeastern Barents Sea, in the Thor Iversenbanken area, exhibited less variation in bottom type. Although we see many exiting landforms on the seabed, the uppermost seabed sediments mainly comprise sandy mud and muddy sand. The biology is dominated by polychaeta that live in the soft sediments. The originally planned mapping area was 6000 km2, with depths from 250 m to 350 m. In addition to this, we have started work in next year's mapping area.

As we head home with data and samples, we look forward to exciting winter-months before heading out on new adventures next year.
