Energetic fluctuations of periods longer than a day are found to transport heat poleward in the Drake Passage. Heat fluxes due to these low-frequency motions are large enough to account for all of the poleward heat transport across the pol ar front necessary to balance the heat Jost to the atmosphere by waters around the Antarctic continent....
