People are being very generous with their time and information.
Birgitte Rugaard Furevik has given me some fantastic satellite images showing the lines of weather fronts, and wind movement - calm areas being dark, and white area indicating turbulence or higher winds. These are areas that are potential dangerous for shipping as changes can occur very quickly and it's more difficult to assess exactly what will happen. You can even see areas of rain in the more 'pitted' areas, and the edge of the frozen coastline is visible - these being taken over the sea in the northern hemisphere. I'm sure I was told more... but it's difficult to take it all in. Strangely they look similar to a piece of work that I made a few days earlier.
Johannes Röhrs has given me a copy of an animation that he has made showing how the waves move the sea up and down but that the water doesn't actually move forward - it doesn't go anywhere other than up and down, but rather it's the energy (generated by the wind, or currents I guess) in the wave movement that moves (does that make sense?). Of course when the wave breaks then water is propelled forward. The red dot is an item dropped into the water to show how the energy in the waves propels it forward.
I have also been given more historical data of instruments, old charts showing salinity and temperature - all of which I find aesthetically pleasing and intriguing, even if I don't entirely understand their function.
