T. W. Wood, A. M. Baptista, J.S. Kuwabara, A.R. Flegal
1995, Limnology and Oceanography (40) 345-358
The two-dimensional numerical model ELAmet was used to investigate the effect of adsorption kinetics on the apparent distribution coefficients of Cu, Cd, and Zn in south San Francisco Bay, California. The numerical experiments were designed to determine whether adsorption kinetics can control the basin-scale variability of the observed partitioning and...
Seasonal-to-interannual fluctuations in surface temperature over the Pacific: effects of monthly winds and heat fluxes
Daniel R. Cayan, Arthur J. Miller, Tim P. Barnett, Nicholas E. Graham, Jack N. Ritchie, Josef M. Oberhuber
1995, Book chapter, Natural climate variability on decade-to-century time scales
Monthly heat fluxes and wind stresses are used to force the Oberhuber isopycnic ocean general-circulation (OPYC) model of the Pacific basin over a two-decade period from 1970 to 1988. The surface forcings are constructed from COADS marine observations via bulk formulae. Monthly anomalies of the fluxes and stresses are...

Multiple indicators (Chl a, C : N ratios, [δ13C]POC, and two classes of lipid biomarker compounds- sterols and phospholipid ester-linked fatty acids) were used to evaluate spatial and temporal variations in the origin of particulate organic matter (POM) in the San Francisco Bay (SFB) estuary. Comparisons were made between the...

Hydrological and thermal response of lakes to climate: Description and modeling
Steven W. Hostetler
1995, Book chapter, Physics and chemistry of lakes
Lake systems continually respond to climatic conditions that vary over broad scales of space and time. The spatial distribution of lakes on the Earth’s surface is indicative of long-term patterns of atmospheric circulation, and the annual cycle of climate over lake basins is reflected in seasonal change in the size...
