Spilhaus Data Composite

Cycles through data projected onto the Spilhaus map. In order of appearance: ocean surface currents colored by temperature, bathymetry, plate boundaries and active submarine hydrothermal vent fields, sea ice concentration, chlorophyll concentration. (Map by Natalie Renier, WHOI Creative )
