Pauline Bergsten is a French intern working at Matís for six months. She is currently on an oceanographic cruise with the Marine Research Institute and is collecting samples for microbial and metagenomics studies. She just sent us news about her experience.
“I took part in the marine sampling campaign 2015 as a representative of Matís. The vessel is Bjarni Sæmundsson, Iceland’s second research vessel. Three or four times a year a journey is organized on that boat all around Iceland with on board a scientific team, each member specialized in a specific field such as plankton and phytoplankton, sea chemistry and ocean acoustic. Sampling and measurements are made at precise locations, almost all of them remaining the same over the years following the same itinerary and sampling plan. We stopped at more than 90 stations during 10 days.
The itinerary is separated into several transects that start close to the coastline and goes relatively far offshore. Each station where we stopped and sampled seawater with a special sampling device called CTD rosette. It allows sampling from the surface all the way to the ocean floor. As soon as the CTD is back on board each scientist comes to collect seawater for further treatment or storage, before the next station.
I was given several tasks related to the four different kinds of samples requested. The quantities of sea water I needed to collect depended on the actual station and thus on the specific treatment that was requested by the team at Matís. These samples will be used to count bacterial numbers by flow cytometry, analysing the species composition and abundance by DNA sequencing and cultivating representative strains from this environment. This activity is part of the EU funded project MicrB3 and Macumba.”
