1990, Science of Total Environment (97-98) 673-684
Arsenic concentrations were determined in fine-grained, oxidized, surface sediments and in two benthic bivalves, Corbicula sp. and Macoma balthica, within San Francisco Bay, the Sacramento/San Joaquin River Delta, and selected rivers not influenced by urban or industrial activity. Arsenic concentrations in all samples were characteristic of values reported for uncontaminated...
Time allocation by northern fulmars during the breeding season
Scott A. Hatch
1990, Ornis Scandinavica (21) 89-98
Averaged over the whole breeding cycle (pre-laying through mid-chick stage), breeding fulmars spent about 39% of their time at the breeding site and 61% of their time at sea. Annual means of site occupancy before egg-laying were positively correlated with breeding success, suggesting that time allocation was a sensitive indicator...

Comparison of three techniques for the capture and transport of impounded subyearling American shad
T. W. H. Backman, R. M. Ross
1990, Progressive Fish-Culturist (52) 246-252
A comparison of three techniques for the capture of impounded juvenile American shad (Alosa sapidissima; 50–100 mm total length) showed a 1‐m‐diameter entrainment net to be an order of magnitude more efficient than a black rectangular tank, which relied on a light source to attract the fish at night. A...
Coupled variations in helium isotopes and fluid chemistry: Shoshone Geyser Basin, Yellowstone National Park
E.H. Hearn, B. M. Kennedy, A.H. Truesdell
1990, Geochimica et Cosmochimica Acta (54) 3103-3113
Early studies of 3He/4He variations in geothermal systems have generally attributed these fluctuations to either differences in the source of the magmatic 3He-rich helium or to local differences in the deep flux of magmatic 3He-rich helium. Kennedy et al. (1987), however, show that near-surface processes such as boiling and dilution may also drastically...
