1. Collaborative Research: Replicate Coring at WAIS Divide to Obtain Additional Samples at Events of High Scientific Interest [severinghaus_1043421]
This award supports a project to obtain samples of ice in selected intervals for replication and verification of the validity and spatial representativeness of key results in the WAIS Divide ice core, ...


2. Fugitive Gases (Helium, Neon, and Oxygen) in the WAIS Divide Ice Core as Tracers of Basal Processes and Past Biospheric Carbon Storage [severinghaus_1143619]
This award supports a project to extend the study of gases in ice cores to those gases whose small molecular diameters cause them to escape rapidly from ice samples (the so-called "fugitive gases"). ...


3. Methane isotope variations covering the Holocene from the WAIS Divide core [NSIDC-0649]
This award supports a project to better predict how natural CH4 emissions will respond to and force future climate change through a detailed study of the global biogeochemical cycles that control ...


4. WAIS Divide Ice Core Discrete CH4 (80-3403m) [NSIDC-0631]
A project to develop a 50 yr resolution methane data set that will play a pivotal role in developing the WAIS Divide timescale as well as providing a common stratigraphic framework for comparing climate ...
