Record of the early Holocene warming in a laminated sediment core from Cape Hallett Bay (Northern Victoria Land, Antarctica).
This paper presents an integrated multiproxy approach study (sedimentological, geochemical, preliminary smear-slides diatom assemblages, and 14C ages analyses) performed on a sediment core collected in Cape Hallett Bay (Ross Sea, Antarctica). Sediments record the early Holocene rapid climate changes...

This paper presents an integrated multiproxy approach study (sedimentological, geochemical, preliminary smear-slides diatom assemblages, and 14C ages analyses) performed on a sediment core collected in Cape Hallett Bay (Ross Sea, Antarctica).
