Source and biolability of ancient dissolved organic matter in glacier and lake ecosystems on the Tibetan Plateau
The Tibetan Plateau is the world’s largest and highest plateau and holds the largest mass of ice on Earth outside the icesheets of Greenland and Antarctica, as well as abundant lakes. This study examined the molecular and isotopic signatures of dissolved organic matter (DOM) along with its biolability in glacier ice, glacier-fed streams, and alpine lakes on the Tibetan Plateau. The aim was to a...
متن کاملMulti-Decadal Record of Ice Dynamics on Daugaard Jensen Gletscher, East Greenland, from Satellite Imagery and Terrestrial Measurements
The history of ice velocity and calving front position of Daugaard Jensen Gletscher, a large outlet glacier in East Greenland, is reconstructed from field measurements, aerial photography and satellite imagery for the period 1950–2001. The calving terminus of the glacier has remained in approximately the same position over the past 50 years. There is no evidence of a change in ice motion betwee...
متن کاملAnatomy of a Dansgaard-Oeschger warming transition: High-resolution analysis of the North Greenland Ice Core Project ice core
[1] Large and abrupt temperature oscillations during the last glacial period, known as Dansgaard-Oeschger (DO) events, are clearly observed in the Greenland ice core record. Here we present a new high-resolution chemical (2 mm) and stable isotope (20 mm) record from the North Greenland Ice Core Project (NGRIP) ice core at the onset of one of the most prominent DO events of the last glacial, DO-...
متن کاملMultiyear accumulation and temperature history near the North Greenland Ice Core Project site, north central Greenland
This paper presents a comparison of two independent methods of estimating subseasonal accumulation across the interior of Greenland. These methods, highresolution snow pit studies and atmospheric modeling, have differing spatial and temporal resolution, but both can estimate net accumulation for subseasonal and shorter periods. The snow pit approach is based on a documented relationship between...
متن کاملGlacier advance during Marine Isotope Stage 11 in the McMurdo Dry Valleys of Antarctica
We mapped six distinct glacial moraines alongside Stocking Glacier in the McMurdo Dry Valleys, Antarctica. Stocking Glacier is one of several alpine glaciers in the Dry Valleys fringed by multiple cold-based drop moraines. To determine the age of the outermost moraine, we collected 10 boulders of Ferrar Dolerite along the crest of the moraine and analyzed mineral separates of pyroxene for cosmo...
