Currents

→ You have to take the weather into account continuously, for example.
→The Currents
→ There is something that inhibits you – you cannot act as you would on land. Every simple movement is more tiring.

People sometimes ask us to put something on the bottom of the sea, for example.
They have no idea how difficult this is. The practical difficulties apply mainly to activities we need to perform for scientists. Towing instruments, installing laboratory equipment onboard, access to buoys at sea with a small boat, placing and recovering moorings, taking whatever sample of bottom, water, fauna. You cannot just do those things; there are currents, animals, there is the buoyancy of the water that you have to fight.

It is important to understand how heat is transported by the ocean currents to the ice and how the changing temperature of the water influences ice melting. → How does warm water intrusion into the fjords in Greenland and under the ice shelves in Antarctica affect the outlet glaciers and ice shelves? How do the currents evolve as a result?

All the patterns that appear upon the surface of the ocean and movement of the water itself is brought about by the wind in all its gymnastic manifestations or vibrations. Water from all the oceans and every sea is constantly moving across the world in great migratory currents replenishing and changing themselves through this exchange.

Walls of 40m can form for example, because of differences in depth. The ocean pushes upwards + creates strong currents. Hence what’s marked as an "area to be avoided" on the map.

I spent some time in the Shetland Islands in Scotland. To get from mainland Shetland to Fair Isle you either take a boat, which is called The Good Shepherd, or a plane. I became very seasick when I took that boat. That was strange because the water was calm. The waves crush the cliffs all the time so there’s an almost invisible current.
