Ocean Deoxygenation: Everyone’s Problem

In May 2022, HypOnFjordFish were out on yet another research cruise to some of our Norwegian fjords. In this post we would want take you on a visual journey through what life onboard a research vessel can be like.

A few weeks ago, several of the HypOnFjordFish group members travelled to Liège in Belgium for the 53rd International Colloquium on Ocean Dynamics (3rd GO2NE Oxygen Conference) from the 16th to the 20th of May. This was the perfect arena for us to share some our work and for us to connect and discuss with other scientists working on ocean deoxygenation.

Last week, Frank Midtøy and Heikki Savolainen went to Korsfjorden on the research vessel Emiliana to begin the preliminary process of testing gear to collect mesopelagic fish eggs. No one has ever been able to conduct lab experiments with healthy mesopelagic species, so establishing a lab population would be a major breakthrough in allowing us to study them.

There have been several excellent efforts to raise awareness about ocean deoxygenation and bring scientists
