Six hard-water lakes were sampled May-August for 14 yr in a 52,000 km2 catchment to identify the mechanisms that regulate the spatial and temporal variability of net atmospheric exchange of CO2 of lak...
Evaporation and groundwater fluxes are thought to regulate hydrologic variability in lakes of the northern Great Plains, but little is known of how the relative importance of these processes may vary...
Solar ultraviolet (UV) radiation can have deleterious effects on coral assemblages in tropical and subtropical marine environments, but little information is available on UV penetration into ocean wa...
Zooplankton biomass in Chesapeake Bay was estimated with an optical plankton counter mounted on a towed body (Scanfish). Normalized zooplankton biomass size spectra were calculated for three Ba...
In situ measurements in a shallow water sediment were performed using three different modules—a microprofiling unit, a transparent benthic chamber, and a planar optode periscope. The combined d...
Total and dissolved inorganic phosphorus (IP) was measured in both rainwater and aerosol samples collected from two remote coastal areas: on the island of Crete (Greece) and at Erdemli (Turkey). Part...
