![Surface satellite imagery and multibeam swath bathymetry of Barilari Bay. Sediment core locations are marked. Present glacial flow lines and flow divides are indicated. Bathymetric profile line used in Figure 8 is drawn for reference. Historic ice loss is delineated from Ferrigno et al. (2008). Proposed Little Ice Age ice shelf extends to the outer fjord. Inset (a): Oblique view of grounding line and grounding zone wedge in inner Barilari Bay (4× vertical exaggeration).]()
![Schematic diagram of Barilari Bay. The bathymetric profile traced along the fjord axis in A and B can be found in Figure 2. Cross-section view is looking to the northeast. Numbers refer to environmental and sedimentological processes active during this each climate event. (A) Little Ice Age conditions: 1—fjord-wide ice shelf; 2—increased sea ice coverage and fast ice; 3—decreased primary productivity; 4—reduced basal melting of the ice shelf; 5—ejection of meltwater plumes of fine-grained siliciclastic sediment; 6—glacial advance to maximum Holocene positions over a fluted grounding zone wedge; 7—turbidity currents emanating from the grounding line. (B) Modern seasonally marine conditions in Barilari Bay: 1—seasonally open marine conditions; 2—increased primary productivity; 3—increased iceberg calving and ice-rafted debris deposition; 4—retreated glacial positions with frontal melting at the calving fronts; 5—absence of turbidity currents and meltwater plumes.]()

![Late Holocene glacial advance and defined Little Ice Age (LIA) glacial intervals in the Southern Hemisphere. Cal.—calibrated; NPI—Northern Patagonian Ice Field; SPI—Southern Patagonian Ice Field; AP—Antarctic Peninsula; NH—Northern Hemisphere; LIS-A—Larsen Ice Shelf A. Black diamonds indicate dated glacial deposits. Hollow black diamonds indicate inferred ages of glacial advance. Black diamonds with dotted lines between them bracket possible advance age ranges. Solid black line indicates defined LIA glacial period. Age error bars are included for AP records where appropriate. Periods of abrupt (A.D. 1275–1300) and intensified (A.D. 1430–1455) cooling and ice growth in Iceland and Arctic Canada attributed to volcanic forcing (Miller et al., 2012) are shaded in gray, as is the classic Northern Hemisphere LIA (A.D. 1550–1800).
