[1] We use planktonic oxygen isotope (dO) records spanning the last 30,000 years (kyr) to constrain the magnitude and spatial pattern of glacial cooling in the upwelling environment of the eastern equatorial Pacific (EEP). Fourteen new downcore dO records were obtained from surface-dwelling planktonic foraminifera Globigerinoides sacculifer and Globigerinoides ruber in eight cores from the upwe...

A continuous record of lacustrine sedimentation capturing the entire full-glacial period was obtained from Arolik Lake in the Ahklun Mountains, southwestern Alaska. Fluctuations in magnetic susceptibility (MS), grain size, organic-matter (OM) content, C/N ratios, C, and biogenic silica (BSi) record marked environmental changes within the lake and its watershed during the last 33 cal ka. Age con...

Benthic foraminifera assemblages from two fjords of Svalbard—Kongsfjorden and Krossfjorden in the High Arctic—have been studied. The show three characteristic fjords’ glacial proximal, middle distal parts. Cassidulina reniforme– Elphidium clavatum, Textularia spp. assemblage dominates fauna near glacier proximal that indicates increased sedimentation meltwater runoff; a Nonionellina labradorica...

Layers of sediment that are deposited on the floor of Lake Ohau, New Zealand, offer a means to reconstruct past climate conditions in the Southern Hemisphere at subdecadal and annual resolution. A robust understanding of the modern physical processes that control the influx and dispersal of sediment in the lake is required to reconstruct climate from these sedimentary archives. In this study, w...

In tectonically active mountain ranges, the landscape is shaped by interplay of erosion/sedimentation and driven crustal deformation. Characteristic landforms such as moraines, wind gaps, fault scarps, river terraces can be used to decipher evolution. However, available data often allow for different interpretations. Here we study Pradol (Pradolino) Valley in Western Slovenia, a deeply incised ...

Deep-sea sediment pore fluids contain a record of past glaciations in their [Cl] and N18O. The signal of the Last Glacial Maximum (LGM) ice volume increase remains in the pore fluids as a local peak in each of these species. Using a one-dimensional model to account for the diffusive and advective transport within the sediment column since the LGM, the past bottom water salinity and NOseawater v...

A high-resolution multibeam survey from a portion of the San Simeon Channel (offshore Morro Bay, California) captured zone recurring troughs and ridges adjacent to prominent submarine meander bends. Through an integrated study using surveying data, sediment core analysis, radiocarbon dating, stable isotope measurements, we hypothesize that turbidity current event frequency was higher during lat...

[1] Estimates of 20th Century sea level rise are typically 1.5 to 2 mm/y, with a steric contribution of (0.5 ± 0.2) mm/y. Estimates of the eustatic contribution vary widely between 1.1 and +1.3 mm/y. We attempt an independent estimate of eustatic sea level rise based on the measured freshening of the global ocean, and with attention to the contribution from melting of sea ice (which affects fre...

The terrestrial Quaternary stratigraphic record of British Columbia is largely a product of brief depositional events separated by long periods of nondeposition and erosion. Thick, stratified Quaternary sediments are present mainly in valleys and coastal lowlands and accumulated during periods of growth and decay of the Cordilleran Ice Sheet. At glacial maxima, till was deposited over large are...
