GOAL hydrographic gridded data set for the Northern Antarctic Peninsula, Southern Ocean
This gridded product was built by optimally interpolate the Brazilian High Latitude Oceanography Group (GOAL) profiles sampled in the Northern Antarctic Peninsula (NAP) during 2003-2019. The profiles were first linearly interpolated onto 114 depth levels, and then optimally interpolated in space usi...

This gridded product was built by optimally interpolate the Brazilian High Latitude Oceanography Group (GOAL) profiles sampled in the Northern Antarctic Peninsula (NAP) during 2003-2019.
