Deep Pacific storage of respired carbon during the last ice age: Perspectives from bottom water oxygen reconstructions
Reconstructions of past changes in dissolved oxygen concentrations in the abyssal ocean
are of interest to paleoceanographers because of their potential to help characterize and …

Southern Ocean glacial conditions and their influence on deglacial events
Abstract The Southern Ocean is an important regulator of global CO2 levels and likely had a
key role in lowering atmospheric CO2 levels during the Last Glacial Maximum (LGM) and …

Large climate-driven changes of oceanic oxygen concentrations during the last deglaciation
SL Jaccard, ED Galbraith - Nature Geoscience, 2012 - nature.com
During the last glacial termination, the solubility of gases in the ocean decreased as ocean
temperatures rose. However, marine sediments have not unanimously recorded ocean …

Glacial expansion of oxygen-depleted seawater in the eastern tropical Pacific
Increased storage of carbon in the oceans has been proposed as a mechanism to explain
lower concentrations of atmospheric carbon dioxide during ice ages; however, unequivocal …

230Th Normalization: New Insights on an Essential Tool for Quantifying Sedimentary Fluxes in the Modern and Quaternary Ocean
Abstract 230Th normalization is a valuable paleoceanographic tool for reconstructing high‐
resolution sediment fluxes during the late Pleistocene (last~ 500,000 years). As its …

North Pacific deglacial hypoxic events linked to abrupt ocean warming
Marine sediments from the North Pacific document two episodes of expansion and
strengthening of the subsurface oxygen minimum zone (OMZ) accompanied by seafloor …

Nitrogen isotopes in bulk marine sediment: linking seafloor observations with subseafloor records
The stable isotopes of nitrogen offer a unique perspective on changes in the nitrogen cycle,
past and present. However, the presence of multiple forms of nitrogen in marine sediments …

Ocean dynamics, not dust, have controlled equatorial Pacific productivity over the past 500,000 years
Biological productivity in the equatorial Pacific is relatively high compared with other low-
latitude regimes, especially east of the dateline, where divergence driven by the trade winds …

No iron fertilization in the equatorial Pacific Ocean during the last ice age
Abstract The equatorial Pacific Ocean is one of the major high-nutrient, low-chlorophyll
regions in the global ocean. In such regions, the consumption of the available macro …
