Summer 2010 Field Report: La Paz, Mexico

During the summer of 2010 Master’s degree candidate Tom Bell completed his field research in the CIBNOR desert preserve near La Paz, BCS, Mexico. From June to August, Tom monitored lateral litter flux experiments, which had commenced in the summer of 2009. Collection of vertical and lateral litter traps was completed over two time . . . → Read More: Summer 2010 Field Report: La Paz, Mexico

GCRG Heads for the Skies with NASA-Funded Research

GCRG will work with the National Aeronautics and Space Administration’s Jet Propulsion Lab to measure the greenhouse gas effect on the Arctic. The research team will collect data that will provide unprecedented experimental insights into Arctic carbon cycling, especially the release of the important greenhouse gases such as carbon dioxide and methane. The study . . . → Read More: GCRG Heads for the Skies with NASA-Funded Research

Seasonal Variations of Trace Gas Flux in Mangrove Ecosystem in Baja California Sur, Mexico

IMGA0110

Anthropogenic activities have disrupted biogeochemical cycles with subsequent increases in the emission of radiatively important trace gases. Wetlands are natural sources of CO2, CH4 and N2O with seasonal variations in anthropogenic inputs, temperature, salinity, and water modulating emissions. Variations in trace gas flux in mangrove ecosystems using eddy covariance, soil coring, leaf litter sampling, . . . → Read More: Seasonal Variations of Trace Gas Flux in Mangrove Ecosystem in Baja California Sur, Mexico

Land-atmosphere carbon fluxes along a thaw-lake chronosequence on the Arctic Coastal Plain of Alaska

Thaw lakes and vegetated thaw lake basins (VTLBs) are common features in permafrost zones and can comprise a large proportion of the land surface [1-7] (Figure 1). Thaw lakes on the Arctic Coastal Plain (ACP) of Alaska are estimated to have begun forming approximately 10,000 years ago in the Holocene when the climate was . . . → Read More: Land-atmosphere carbon fluxes along a thaw-lake chronosequence on the Arctic Coastal Plain of Alaska

Vertical and Lateral Carbon Flux in a Larrea/Cardon Ecosystem near La Paz, BCS, Mexico

Lateral transport of carbon by wind and water in the form of litter fall could represent a significant portion of carbon entering or exiting an ecosystem. In La Paz, Baja California Sur, Mexico, GCRG established a permanent Eddy Covariance tower in 2001. Eddy Covariance tracks daily, seasonal and yearly ecosystem carbon flux, but may . . . → Read More: Vertical and Lateral Carbon Flux in a Larrea/Cardon Ecosystem near La Paz, BCS, Mexico

Air-Sea CO2 Exchange in the Coastal Marine Zone

The objective of this study is to identify and describe the patterns of and controls on air-sea CO2 exchange at distinct geographic locations (eg, Barrow AK, Bodega Bay CA, San Diego CA) and understand important characteristics of physical and biological processes of the coastal sea.

Personnel: Hiroki Ikawa, Walt Oechel Duration: 2006 – present

What is a “Feedback Loop?”: Dr. Oechel on ABC News

Recently, it was another beautiful, sunny day out on the Arctic tundra. Scientists say the Arctic is melting — and fear it could help send Earth into a global warming tailspin. It may sound nicer that way — but it’s a big problem for the Earth. Scientists say the warm weather adds to global . . . → Read More: What is a “Feedback Loop?”: Dr. Oechel on ABC News

Dr. Oechel on KPBS Radio: Realities of Global Warming

Tidal waves, tornadoes, and the big freeze. The Day After Tomorrow is the latest disaster movie to hit the big screen. But how much of it is based on fact? We’ll talk about the realities of global warming.
