Fig. 4: Illustration of the potential processes influencing Be isotopes within Ferrero Bay.
From: Holocene melting of the West Antarctic Ice Sheet driven by tropical Pacific warming
a Open marine, sub-ice-shelf, and subglacial environments are defined by different geochemical compositions27,34. b Melting of icebergs and sea ice near the calving line releases 10Be which is rapidly scavenged by diatom frustules and organic matter before becoming advected under the ice-shelf with other marine material by ocean currents such as intruding CDW. c Meltwater rich in 10Be is released from the ice-shelf base and scavenged by fine-grained sediment delivered from the grounding line. This figure was modified from Yokoyama et al.24 and White et al.27.
