I am looking for some quality biophysical data products (ocean temperature, salinity, dissolved oxygen, Chl-a etc.), especially in-situ ones, for the water bodies situated near the arctic sea and Antarctica. Profiling Floats, Ice-Borne Observing Systems, Ice/Snow Surface Drifters etc. are some of the systems for acquiring polar ocean datasets. So far, I have come across the following sources:
Are these sources good enough to represent ocean dynamics within the polar circle? I would much appreciate it if you could point out some other sources, whether it is in-situ, satellite or model, for understanding polar ocean dynamics.
