More than 3700 fertilized toad eggs were used in a series of
studies designed to determine the effects of UV-B radiation (290-
315 nm) on temporal developmental patterns, systematic development
and viability prior to metamorphic climax. The eggs were
exposed to radiation from either "white-light" fluorescent lamps
(Vita-Lite, Duro-Test Corporation,...
Artificial substrates colonized by diatoms from Yaquina Estuary, Oregon, were exposed to solar visible radiation and three levels of ultraviolet radiation (UV-B, 290-320 nm). Flow-through microcosms were constructed inside a glasshouse to serve as chambers for the artificial substrates. The artificial substrates were sampled during three spring/summer experiments. Chlorophyll a...
Current meter moorings maintained over the Oregon continental shelf in 1973 and 1975 clearly show the difference between winter and spring oceanographic regimes and the rapid transition between the regimes. In winter the mean alongshore current is northward at all depths and strongest near shore; there is no mean vertical...
Seasonal cycles of coastal wind stress, adjusted sea level (ASL), shelf currents, and water
temperatures off the west coast of North America (35°N to 48°N) are estimated by fitting annual and
semiannual harmonics to data from 1981-1983. Longer records (9-34 years) of monthly ASL indicate
that these two harmonics adequately...
Moored observations of currents and temperatures made in the upper 600 m on
eddy-resolving scales over a 2-year period are used to examine the spatial and temporal
characteristics of the California Current mesoscale circulation. The observations were
made at three principal longitudes: 124°W, 126°W, and 128°W in the vicinity of...
