The Southern Ocean during the ice ages: A review of the Antarctic surface isolation hypothesis, with comparison to the North Pacific
Abstract The Southern Ocean is widely recognized as a potential cause of the lower
atmospheric concentration of CO 2 during ice ages, but the mechanism is debated. Focusing …

Southern Ocean upwelling, Earth's obliquity, and glacial-interglacial atmospheric CO2 change
Previous studies have suggested that during the late Pleistocene ice ages, surface-deep
exchange was somehow weakened in the Southern Ocean's Antarctic Zone, which reduced …

The seasonal cycle of nitrogen uptake and nitrification in the Atlantic sector of the Southern Ocean
M Mdutyana, SJ Thomalla, R Philibert… - Global …, 2020 - Wiley Online Library
Net primary production (NPP) fueled by nitrate is often equated with carbon export, providing
a metric for CO2 removal to the deep ocean. This “new production paradigm” assumes that …

The nitrogen isotopic composition of tissue and shell‐bound organic matter of planktic foraminifera in Southern Ocean surface waters
We present the first nitrogen isotope (δ15N) measurements of planktic foraminifera,
paleoceanographically important zooplankton, from the nutrient‐rich waters of the modern …

The Impact of Incomplete Nutrient Consumption in the Southern Ocean on Global Mean Ocean Nitrate δ15N
It is understood that the global mean ocean nitrate δ15N is set by the δ15N of the input of
fixed nitrogen (N) to the ocean (mostly N2 fixation) and the net isotopic discrimination of …

Ice age‐Holocene similarity of foraminifera‐bound nitrogen isotope ratios in the eastern equatorial Pacific
Bulk sediment δ15N records from the eastern tropical Pacific (ETP) extending back to the
last ice age most often show low glacial δ15N, then a deglacial δ15N maximum, followed by …

Assessment of C, N, and Si isotopes as tracers of past ocean nutrient and carbon cycling
Biological productivity in the ocean directly influences the partitioning of carbon between the
atmosphere and ocean interior. Through this carbon cycle feedback, changing ocean …

Nutrient dynamics and biogeochemical processes at the Polar front of Indian sector of the Southern Ocean: Influence of Circumpolar deep water intrusion
Abstract The Circumpolar Deep water (CDW) is one of the largest water masses in the
Southern Ocean. The cross-frontal flow of the CDW is a vital mode of redistribution and …
