Sampling with Porsild

Porsild is the research vessel of Arctic Station and our workplace when we go out for collecting samples. 

It’s a 15m long and 5m wide vessel that can transport 12 passengers and three crew members during daytrips. Eight people can stay over-night on board.

Prior to sampling we plan which stations we are going to visit and which sampling gear will be needed. This has to be done with care as space on the ship is limited so we only want to take equipment that is absolutely necessary.

In order to get an overview over the marine biodiversity around Disko Island, Porsild takes us to places such as Disko Fjord and deeper waters south of Qeqertarsuaq.

On board we use several sampling tools and two winches. The larger winch has a 400m wire and a lifting capacity of two tons. The smaller winch has a wire length of 800m and is mainly used for lighter sampling such as with the plankton net.
