Underwater eddy covariance measurements of heat, salt, and dissolved oxygen
Underwater eddy covariance measurements of heat, salt, and dissolved oxygen
We will study the exchange of salt, heat, and oxygen between sea ice and the underlying seawater using eddy correlation. Measurement of ice-ocean oxygen exchange will allow us to non-destructively measure net ecosystem exchange, which will support other primary production estimates made by K. Campbell. Measurements of heat exchange will allow for estimation of ice melt/growth, which will contribute to an understanding of the under-ice habitat for sea ice algae. Measurements of salt exchange will improve our understanding of solute cycling through the sea ice, contributing to a better understanding of ice algae nutrient supply, and ice-ocean-atmosphere connections.
