Phytoplankton pigments constitute many more compounds than chlorophyll a that can be applied to study phytoplankton diversity, populations, and primary production. In this study, field measurements were applied to develop ocean color satellite algori

To evaluate levels of primary production and community metabolism in Lake Erie, we conducted incubations with 18 O-labelled water and determined the ratio of respiration to primary production (R:P) during the summer and early fall of 2002. The epilim

A first-return laser rangefinder deployed from a low-flying helicopter provided inexpensive, repeatable, and high-resolution measurements of the shape of the outer forest canopy in stands of four successional stages on the Maryland coastal plain. The

In this study, we compare stable isotopic compositions of di-oxygen (O 2 ) and nitrous oxide (N 2 O) in two depth profiles at the well-characterized deep water station ALOHA (A Long-term Oligotrophic Habitat Assessment) in the subtropical North Pacif

Despite the importance of O2 in biogeochemical processes, relatively few environmental studies have incorporated stable isotope information to assess the origins and cycling of this gas. A major limitation to the routine use of δ18O has been the cos

At present, satellite remote sensing of coastal water quality and constituent concentration is subject to large errors as compared to the capability of satellite sensors in oceanic waters. In this study, field measurements collected on a series of cr

[1] A study of respiration to photosynthesis (R:P) ratios in Lake Superior, based on the fraction of O2 saturation and the isotopic composition of O2, was undertaken to evaluate spatial and temporal variations in the trophic status of a large oligotr

[1] Although the oceans are a significant source of the greenhouse gas nitrous oxide (N2O) to the atmosphere, the magnitude and characteristics of this source are poorly constrained. We present here stable isotope and isotopomer (intramolecular distr
