Arctic and Antarctic forcing of ocean interior warming during the last deglaciation
Funding was provided by an Antarctic Bursary awarded to J.A.S., ERC and NERC grants awarded to L.F.R. (278705, NE/S001743/1, NE/R005117/1) and L.F.R. and J.W.B.R. (NE/N003861/1). Subsurface water masses formed at high latitudes impact the latitudinal distribution of heat in the ocean. Yet uncertaint...
