Hemuqiao Experimental Station

Brief Site Description: 
Taihu Basin, southeastern China
Detailed Site Description: 

The Hemuqiao Hydrological Experimental Station (119°47′05″-119°48′20″, 30°34′05″-30°34′55″, 135ha) located in the upstream of Taihu Basin, China. The catchment is characterized by steep slopes of 25º-45º. Being elevated at 600 m asl in the southwest region, the elevation is decreasing to 160 m asl at the outlet of the catchment. The average annual precipitation is about 1580 mm, and the average annual evaporation and temperature are 805 mm and 14.6ºC, respectively. The underlain bed rocks at catchment mainly consist of sandstone and rhyolitic welded crystal tuff. The vegetation is dominated by Moso bamboo (Phyllostachys edulis), covering about 68% of the whole area. Precipitation during the summer months (June–August) usually produces high-intensity short-duration storm events, while low-intensity rainfall events are more common during the winter months (December–February).  The soil texture in the catchment varies from silt in the topsoil (e.g., 0–40 cm) to silt loam in the subsoil according to the United States Department of Agriculture (USDA) classification system. The soil saturated hydraulic conductivity (Ks ) declines exponentially with depth, especially at sites with thick soils (e.g., valley floor).

Turkey Lakes Watershed Study (TLWS)

Location

47° 2' 60" N, 84° 25' 1.2" W
Brief Site Description: 
Watershed located in the Eastern Temperate Mixed Forest or Great-Lakes St. Lawrence forest region within the Boreal Shield Ecozone. A multidisciplinary whole-ecosystem investigative approach.
Detailed Site Description: 

The Turkey Lakes Watershed (TLW) study is a federal, interdepartmental study established in 1979 to investigate the effects of acid rain on terrestrial and aquatic ecosystems. The 10.5 km2 watershed, located in the Eastern Temperate Mixed Forest on the Canadian Shield, has been the site of multidisciplinary studies on biogeochemical and ecological processes conducted across plot to catchment scales. The whole-ecosystem investigative approach was adopted from the outset and has allowed research to evolve from its original (and continuing) acidification focus to include investigations on the effects of climate change, forest harvesting and other forest ecosystem perturbations. The extensive scientific and support infrastructure allows for collection of a comprehensive data record essential for understanding long-term environmental trends. Data include atmospheric deposition, meteorology, stream hydrology and chemistry, soil, pore and ground water properties, understory and overstory vegetation, lake and outflow physical and chemical properties, and aquatic macroinvertebrate and fish community composition and abundance. These data have contributed to over 400 published research papers and graduate theses. The watershed has also figured prominently in many continent-wide comparisons advancing fundamental watershed theory. The knowledge gained at TLW has influenced pollutant emission and natural resource management policies provincially, nationally and internationally.

AGU Session B060 Microbes in Biogeochemical Cycles: Linking Responses to Ecosystem Processes and Environmental Change

Dear Colleagues,

We would like to invite you to submit abstracts to the AGU Fall Meeting 2021 session B049. Microbes in Biogeochemical Cycles: Linking Responses to Ecosystem Processes and Environmental Change

Post-Doctoral Position in Dryland Biogeochemical Research at University of Texas, El Paso

The University of Texas at El Paso (UTEP) is recruiting a postdoctoral researcher to work on a recently funded National Science Foundation 'Critical Zone Thematic Cluster' grant to study carbon fluxes, ecohydrology, and nutrient availability in dryland ecosystems. The primary goal for this position will be an increased understanding of nutrient cycling (with particular focus on phosphorus) in these carbonate rich dryland soils.

Two full-time job positions with Sierra Nevada Research Institute, Univ. Cal, Merced

The Sierra Nevada Research Institute (SNRI) at UC Merced (http://snri.ucmerced.edu) is seeking two full-time researchers in the specialist track.

Recruitment Period through Monday, Jul 29, 2019 at 11:59pm (Pacific Time)

Associate Specialist (https://aprecruit.ucmerced.edu/JPF00820; $58,000+ salaried)
