Second day with the ROV dives in the Sound sampling bottoms around -30 meters to know how several biological communities have evolved. Haploops (those small crustaceans living in tubes) have almost disappeared; that is bad news. And horse mussels are present in small groups. Now, brittle stars cover most of the muddy beds in the area, together with small gobies, hermit crabs, some starfish… mainly scavengers. Yes, some flatfish taking advantage of this amount of food. And yesterday a thorn skate, but we are missing the important habitats that have sharply declined in here.Read More...

I have never been in the ship for more than couple hours. And to stay on board for not full 3 days looked challenging. As I am not a marine biologist and my profession is in any way related with nature and science, before coming to expedition I was concern about few questions “ What I will do? And how I could help?” First day, I was listening and observing how everybody was preparing for the expedition. Second day was thrilling there was made videos with ROV in Kattegat and was taken a sample of the bottom floor with a dredge. I always loved playing with sand and mud, so I offered my help to look for “treasure”. It was dark, cold, wet and muddy but excitement was higher than that. It was such happy and exciting moments to find different species hiding in that box full of mud.Read More...

Today was our first day of fieldwork of the 2012 expedition. Throughout the day we managed to conduct four surveys with the (ROV) in the area east of the Danish island of Anholt in Kattegat. We filmed lots of interesting habitats and communities. One of the more interesting organisms we met at 35 meters depth was the Norway lobster, Nephrops norvegicus, which is a target species for fishermen in Kattegat. We filmed the orange lobster while it was sitting in one of its characteristic holes, which they make in the mud. Another interesting thing we came across was an area with a beautiful creature called phosphorescent sea pen. This sea pen emits flashes of light, and it almost looks like a flower, as it a “stem” and has a strong red color (see picture).Read More...

Today at noon our chartered expedition vessel the “Hanse Explorer” left Copenhagen to start operations with the underwater robot (ROV) and divers in the Kattegat. That was after a 24 hour stopover in that harbor to load the last pieces of equipment on board. Before that, the Oceana ship had sailed from its shipyard in Bremen, Germany, down the Weser River until reaching the North Sea, then went up the Elba River and the Kiel Canal to the Baltic Sea. This is the beginning of our second Baltic expedition. The results of last years can be found in the habitats and fisheries reports recently published by Oceana.Read More...
