Creator:: Duncan, Robert A. and Hogan, L. G.
Abstract:: Determination of reliable crystallization ages by K-Ar methods for young (<1 Ma), fresh basalts from the seafloor has been frustrated by several effects. The small amounts of radiogenic ⁴⁰Ar developed over these timescales in such low-K rocks are difficult to resolve from predominantly atmospheric ⁴⁰Ar. An additional concern is that...

Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stumps, both healthy and infected by Phellinus weirii (Murr.)Gilbertson, were fumigated with chloropicrin at a clearcut site on Washington s Olympic Peninsula. Vegetation cover on plots adjacent to treated and untreated stumps was evaluated to determine fumigant effects on vascular plants and moss. Ninety-eight vascular...

Creator:: Kirchman, David L., Keil, Richard G., and Wheeler, Patricia A.
Abstract:: The purpose of this study was to test the hypothesis that NH4+ uptake by heterotrophic bacteria in the subarctic Pacific is C limited. Addition of glucose (0.5–1.0 μM) stimulated NH4+ uptake in unfractionated water but had no effect on bacterial abundance. Glucose stimulation of NH4+ uptake was even greater in...

Creator:: Chelton, Dudley B., Schlax, Michael G., Witter, Donna L., and Richman, James G.
Abstract:: The variability of sea level and surface geostrophic currents in the Southern Ocean is investigated from the first 26 months of unclassified Geosat altimeter data (November 1986 to December 1988). Because of problems unique to Geosat, it has been necessary to develop new techniques for analyzing the height data. These...

Creator:: Lee, Zhongping, Carder, Kendall L., Hawes, Steve K., Steward, Robert G., Peacock, Thomas G., and Davis, Curtiss O.
Abstract:: Remote-sensing reflectance is easier to interpret for the open ocean than for coastal regions because the optical signals are highly coupled to the phytoplankton (e.g., chlorophyll) concentrations. For estuarine or coastal waters, variable terrigenous colored dissolved organic matter (CDOM), suspended sediments, and bottom reflectance, all factors that do not covary...

Abstract:: Empirical algorithms for the total absorption coefficient and absorption coefficient by pigments for surface waters at 440 nm were developed by applying a quadratic formula that combines two spectral ratios of remote-sensing reflectance. For total absorption coefficients ranging from 0.02 to 2.0 m⁻¹, a goodness of fit was achieved between...
