Deep Ocean Carbonate Chemistry and Glacial-Interglacial Atmospheric CO2 Changes
Deep Ocean Carbonate Chemistry Glacial-Interglacial Atmospheric CO2
2015/7/17
Changes in deep ocean carbonate chemistry have profound implications for glacial-interglacial atmospheric CO2 changes. Here, we review deep ocean carbonate ion concentration ([CO32–]) changes based on...
Effect of glacial-interglacial sea-level changes on the displacement and stress field in the forearc and along the plate interface of subduction zones
glacial-interglacial sea-level stress
2015/1/4
Combined seismological, space-geodetic and numerical studies have shown that the seismicity at subduction zones may be modulated by tides and glacier fluctuations on timescales of 1–100 a, becau...

glacial-interglacial sea-level changes displacement and stress field forearc and along plate interface subduction zones
2015/1/4
Combined seismological, space-geodetic and numerical studies have shown that the seismicity at subduction zones may be modulated by tides and glacier fluctuations on timescales of 1–100 a, because the...
A GCM Comparison of Plio-Pleistocene Interglacial-Glacial Periods in Relation to Lake El’gygytgyn, NE Arctic Russia
A GCM Comparison of Plio-Pleistocene Interglacial-Glacial Periods Lake El'gygytgyn Arctic Russia
2014/10/21
Until now, the lack of time-continuous, terrestrial paleoenvironmental data from the Pleistocene Arctic has made model simulations of past interglacials difficult to assess. Here, we compare climate s...
Variability of theNorthAtlantic thermohaline circulation during the last interglacial period
NorthAtlantic thermohaline circulation last interglacial period
2014/4/9
Studies of natural climate variability are essential for evaluating its future evolution. Greenland ice cores suggest that the modern warmperiod (the Holocene) has been relatively stable for the past ...
Knickpoint formation, rapid propagation, and landscape response following coastal cliff retreat at the last interglacial sea-level highstand: Kaua‘i, Hawai‘i
Knickpoint formation rapid propagation landscape response following coastal cliff retreat last interglacial sea-level highstand: Kaua‘i Hawai‘i
2014/4/8
Upstream knickpoint propagation is an important mechanism for channel incision,and it communicates changes in climate, sea level, and tectonics throughout a landscape.Few studies have directly measure...
Testing seawater Sr isotopic variability on a glacial-interglacial timescale: An application of latest high-precision thermal ionization mass spectrometry
TIMS Sr isotopes seawater glacial-interglacial cycle
2017/8/9
Stability in seawater 87Sr/86Sr ratios over a glacial-interglacial timescale has gained the consensus, yet inter-site inconsistency exists in the previous data employed for validation of this issue. T...
Glacial-interglacial atmospheric CO2 change：a possible “standing volume” effect on deep-ocean carbon sequestration
Glacial-interglacial deep-ocean carbon atmospheric CO2 change
2009/12/3
So far, the exploration of possible mechanisms for glacial atmospheric CO2 drawdown and marine carbon sequestration has tended to focus on dynamic or kinetic processes (i.e. variable mixing-, equilibr...
Investigating the evolution of major Northern Hemisphere ice sheets during the last glacial-interglacial cycle
Hemisphere ice sheets last glacial-interglacial cycle
2009/12/3
A 2.5-dimensional climate model of intermediate complexity, CLIMBER-2, fully coupled with the GREMLINS 3-D thermo-mechanical ice sheet model is used to simulate the evolution of major Northern Hemisph...
Phosphorus burial in the ocean over glacial-interglacial time scales
Phosphorus burial ocean glacial-interglacial time scales
2010/1/19
The role of nutrients, such as phosphorus (P), and their impact on primary productivity and the fluctuations in atmospheric CO2 over glacial-interglacial periods are intensely debated. Suggestions as ...
Application of sediment core modelling to interpreting the glacial-interglacial record of Southern Ocean silica cycling
sediment core glacial-interglacial Southern Ocean silica cycling
2008/11/5
Sediments from the Southern Ocean reveal a meridional divide in biogeochemical cycling response to the glacial-interglacial cycles of the late Neogene. South of the present-day position of the Antarct...
Quasi-100 ky glacial-interglacial cycles triggered by subglacial burial carbon release
glacial-interglacial cycles subglacial carbon
2008/11/4
A mechanism is proposed in which climate, carbon cycle and icesheets interact with each other to produce a feedback that can lead to quasi-100 ky glacial-interglacial cycles. A central process is the ...
Numerical reconstructions of the Northern Hemisphere ice sheets through the last glacial-interglacial cycle
Northern Hemisphere ice glacial-interglacial cycle
2008/11/4
A 3-dimensional thermo-mechanical ice-sheet model is used to simulate the evolution of the Northern Hemisphere ice sheets through the last glacial-interglacial cycle. The ice-sheet model is forced by...

2008/11/3
Climate simulations of the Eemian interglacial and the last glacial inception have been performed by forcing a coupled ocean-atmosphere general circulation model with insolation patterns of these peri...
