Environmental Geochemistry

s, anthropogenic influences on natural systems, and to use geochemistry as a tool to learn more about various hydrological, biological and physical processes. This group has conducted studies of the Dry Valleys region of Antarctica since 1993 as part of the NSF’s Long-Term Ecological Research (LTER) program. Ongoing projects in Antarctica include drilling into the subglacial ecosystem of "Blood Falls" in the Dry Valleys and measuring glacial melt input into the Southern Ocean in West Antarctica. Additionally, the group has studied of the deposition of mercury on the landscape in the U.S. and in Antarctica, and led investigations of chemical and physical weathering of rocks of high-standing oceanic islands like Taiwan and New Zealand. Members of this group also study the impact of human activities in urban areas on streams and lakes around Ohio.


Paleoceanography

The Paleoceanography group uses information gathered from sea floor sediments to discover how changes in circulation, temperature, sea ice and glacier mass have affected the global climate system throughout Earth’s history. These data from the past are used to assess present and future climate changes. The main focus of this group's research is on the Arctic Ocean and its history during the past several million years. Sea floor sediments contain mineral and biological particles that are used for investigating past climate changes. A common type of biological particles is foraminifers, single-celled, amoeba-like protists that have a shell and either live on the sea bottom or float in the upper water column. There are an estimated 4,000 species living today. Foraminifers are sensitive to changes in their environment such as temperature and salinity, which makes them useful indicators (proxies) of past climate changes.


Satellite Hydrology

This group uses satellite-based measurements to study rivers, lakes, wetlands, and floodplains. Led by Profs. Douglas Alsdorf and Michael Durand, group members primarily use passive and active microwave measurements such as radar to measure surface water and snowpack. This group is working to better quantify the amount of water stored in snowpacks in the United States using satellite measurements. This group is helping define an upcoming satellite, Surface Water and Ocean Topography. Rivers are fundamentally two-dimensional in their structure and function. This is evident in the Amazon River, where the floodplain width is measured in kilometres. Sensitive to climatic changes, arctic lakes pose another hydrologic measurement challenge. SWOT measurements will enable new under- standing of these complex systems. SWOT will track freshwater resources, and measure ocean currents. SWOT is a joint effort between NASA, the Jet Propulsion Laboratory, and the French space agency, CNES.


Glacier Environmental Change

The Glacier Environmental Change group researches patterns, processes, and impacts of environmental change, mostly in glaciated regions. We integrate methods of glacial geology, climatology, hydrology, and biogeochemistry. Specializing in tropical mountain regions, we study sites along the entire American Cordillera, in Africa, and in Central Ohio. Glaciers impact environments and societies on different scales, from valleys to mountain ranges, spanning far into Earth’s past. Understanding glacier environmental changes requires many techniques and perspectives. Precise measurements from sensors on satellites and airplanes quantify ongoing glacier volume changes; landforms and lake sediments reveal past glacier-climate changes; the hydrochemistry of surface waters reflects glacier melt contribution; and computer simulations help explain past and future dynamics.


Polar Meteorology

The Polar Meteorology group has developed a model (Polar MM5) that is used to forecast weather conditions in the polar regions. The model has been used to stimulate conditions on the North American continent during the last ice age. In addition to weather prediction, the Polar MM5 model has been used for several simulations that examine the current and past climates over ice sheets, including one that illustrates conditions on the North American continent during the last ice age. The Polar Meteorology Group also used the MM5 model to create what is called the Antarctic Mesoscale Prediction System (or AMPS). AMPS is a forecasting system used to make weather forecasts for Antarctica and the surrounding Southern Ocean in support of the

The facility has storage capacity of ~140,000 rock samples and more than 30,000 samples have been catalogued already. The sample collections are available for researchers, educators, and museums to use. An online database and educational materials are available to help educate the public about polar geology.

1980s photogrammetrist Henry Brecher conducted aerial photographic surveys of major Greenland glaciers. 1990s Dr. Ellen Mosley-Thompson obtained ice cores from multiple locations, including GITS. Dr. Ken Jezek conducted radar studies in Greenland's accumulation and ablation zone. In 1995, Ken Jezek was at Swiss Camp. 2005

Jason Box returned to Greenland to: 1.) obtain an ice core from a position in southeast Greenland where the Polar MM5 model simulates a maximum in snow accumulation, 2.) install time lapse cameras pointed at two outlet glaciers, and 3.) conduct supra-glacial melt lake measurements. 2007 In June, 2007, Jason Box established time lapse cameras beside 5 major west Greenland outlet glaciers. In July–September, Jason Box prepared for and occupied a camp near the Arctic Circle for 7 weeks during which time he conducted surface energy budget (melt) and supra-glacial melt lake measurements. 2008 During a 3-week field campaign, Jason Box, Ian Howat, Slawek Tulaczyk, and Yushin Ahn conducted measurements on Store Glacier, west Greenland. Ian Howat installed GPS sensors on Store Glacier in west Greenland. 2009 Jason Box installed time lapse cameras at
