Why we care about copepods
Copepods are arguably Norway’s most important animals, yet largely unknown to the general public. Drifting with the ocean currents, these organisms set the foundation for a large part of the production of fish, seabirds and mammals in the Nordic Seas. In this talk you will learn about the intriguing biology and behavior of these tiny creatures, strategies they take to survive in the highly seasonal environments of our latitudes and how they may be affected by a warmer ocean climate.

Sink or Swim
Microscopic Ocean Plants help to regulate our climate by taking carbon dioxide from the atmosphere and transferring it to the deep ocean as they sink. But we aren't sure how this happens - they grow happily at the surface. One answer is that they end up sticking together into larger particles, sometimes 'ballasted' by a dense particle of chalk or silicate. This can give them enough size and density to sink but the rate they sink at is still something we want to understand.
We think that properties like shape are important as well. In this talk we will test some of these ideas - Ill set up the experiments and you can predict the answers - if you are especially enthusiastic you can set them up as well and share them on Twitter before or afterwards!

Life and science in a research camp in central Greenland
Greenland is covered by a large ice cap. Scientists travel to remote, central Greenland to study the ice and its surrounding climate. How do scientists travel there? How do they live there? What work do they actually do there, and why? Join us for a chat with one of the scientists who spent several weeks at the international research camp EastGRIP, and find out!
