The use of chemical tracers to understand ecosystem interactions in the marine environment has gained increasing popularity over the past three decades. Carbon isotope abundances in organic matter sources in the marine system vary...
The δ13C value of foliage respiration has been considered a constant in the past and modeling efforts have assumed that the δ13C value of foliage respiration is constant and is directly related to substrate without any fractionation....
Rates of U(VI) release from two field-aggregated and contaminated composite sediments were collected from the seasonally saturated lower vadose zone of the US Hanford 300 Area were examined in stirred flow-cell reactors. Kinetic U(VI)...
As the Arctic warms, the ~277 Pg of carbon stored in permafrost peatlands faces an uncertain fate. Arctic and Subarctic peatlands are likely to release more methane (CH4) as permafrost thaw releases formerly-frozen carbon, thaw-induced...
As low-lying areas, deltas are sensitive to changes associated with advance taking place on the land and in the ocean. The pattern of change in shoreline positions over time can be used as an indicator of changes in land and/or ocean...
Zinc acts as a micronutrient in the ocean, capable of influencing and potentially controlling phytoplankton productivity and community structure. Thus, it is important to quantify the distribution of dissolved Zn in the oceans, in...
Stalagmites, or speleothems, are secondary cave deposits that record the isotope and trace element composition of the parent dripwaters within their crystal matrix. Changes in dripwater oxygen and carbon isotopes (δ18O and δ13C) and...
