Journal ArticleDOI
Glacial/interglacial wetland, biomass burning, and geologic methane emissions constrained by dual stable isotopic CH4 ice core records
TL;DR: Dual stable isotopic methane records from four Antarctic ice cores provide improved constraints on past changes in natural methane sources and show that tropical wetlands and seasonally inundated floodplains are most likely the controlling sources of atmospheric methane variations for the current and two older interglacials and their preceding glacial maxima.
Journal ArticleDOI
Industrial-era decline in subarctic Atlantic productivity
Matthew B. Osman,Sarah B. Das,Luke D. Trusel,Matthew J. Evans,Hubertus Fischer,Mackenzie M. Grieman,Sepp Kipfstuhl,Joseph R. McConnell,Eric S. Saltzman +8 more
TL;DR: The results suggest that the decline in industrial-era productivity may be evidence of the predicted collapse of northern Atlantic planktonic stocks in response to a weakened Atlantic Meridional Overturning Circulation, and may result in further productivity declines across this globally relevant region.
Journal ArticleDOI
Glacio-chemical study spanning the past 2 kyr on three ice cores from Dronning Maud Land, Antarctica 2. Seasonally resolved chemical records
TL;DR: The ammonium, calcium, and sodium concentrations from three intermediate depth ice cores drilled in the area of Dronning Maud Land, East Antarctica, have been investigated by as mentioned in this paper.
Journal ArticleDOI
Sulphate record from a Northeast Greenland ice core over the last 1200 years based on continuous flow analysis
Matthias Bigler,Dietmar Wagenbach,Hubertus Fischer,Josef Kipfstuhl,Heinrich Miller,Stefan Sommer,Bernhard Stauffer +6 more
TL;DR: In this article, a 150 m deep ice core from the low-accumulation area of northeast Greenland was analyzed for sulphate, calcium, sodium and electrolytical meltwater conductivity at a depth resolution of approximately 1 cm by continuous flow analysis (CFA).
Journal ArticleDOI
A model‐based interpretation of low‐frequency changes in the carbon cycle during the last 120,000 years and its implications for the reconstruction of atmospheric Δ14C
TL;DR: In this paper, an ocean/atmosphere/biosphere box model of the global carbon cycle (BICYCLE) was proposed to reproduce low-frequency changes in atmospheric CO2 as seen in Antarctic ice cores.
