We used water d2H and d18O from ca. 1000 lakes sampled in the 2007 U.S. Environmental Protection Agency’s National Lakes Assessment (NLA) to assess two hydrological variables—evaporation as a percent...
Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes
We present flux measurements of dissolved silicon (DSi), biogenic Si (BSi), and dissolved inorganic nitrogen (DIN) and phosphorus (DIP) on a temperate salt marsh in Narragansett Bay, Rhode Island, ove...
We measured the flux of water through a beach at the head of Catalina Harbor,California, by monitoring the water table in a transect of wells perpendicular to the shoreline. During a24-h period, the v...
The average length of time water remains within the boundaries of an aquatic system is a key parameter controlling the system’s biogeochemical behavior. This timescale, generally referred to as t...
Applications of transport time scales are pervasive in biological, hydrologic, and geochemical studies yet these times scales are not consistently defined and applied with rigor in the literature. We ...
