Every year, from December to April, anthropogenic haze spreads over most of the North Indian Ocean, and South and Southeast Asia. The Indian Ocean Experiment (INDOEX) documented this Indo-Asian haze at scales ranging from individual particles to its contribution to the regional climate forcing. This study integrates the multiplatform observations...
Five years (1997–2002) of northern California Current SeaWiFS ocean color data put cold, low salinity hydrographic anomalies observed in summer 2002 into a spatial/temporal context and present their biological ramifications. Monthly mean chlorophyll concentrations were >1.0 mg m–3 larger than the previous 3 year average over the entire shelf from...
Physical and biological fields in the coastal transition zone off northern California were measured during February, March, May and June 1987 in an extended alongshore region between 60 km and 150 km offshore. The spring transition, as seen in coastal sea level and winds, occurred in mid-March. Surface variability during...
High concentrations of chlorophyll are found in the California Current System over
300 km offshore, far from the productive coastal upwelling region, and between 150 and
250 m, well below the depth to which photosynthetically active solar radiation penetrates.
This exceptionally deep chlorophyll feature is formed near the coast and...
The evolution of oceanographic conditions in the upwelling region off northern Chile
(18°–24°S) between 1996 and 1998 (including the 1997–1998 El Niño) is presented using
hydrographic measurements acquired on quarterly cruises of the Chilean Fisheries Institute, with
sea surface temperature (SST), sea level, and wind speeds from Arica (18.5°S), Iquique...
Satellite-derived data provide the temporal means and seasonal and nonseasonal
variability of four physical and biological parameters off Oregon and Washington
(41°–48.5°N). Eight years of data (1998–2005) are available for surface chlorophyll
concentrations, sea surface temperature (SST), and sea surface height, while six years of
data (2000–2005) are available for...
Mars Pathfinder successfully landed at Ares Vallis on July 4, 1997, deployed and navigated
a small rover about l00 m clockwise around the lander, and collected data from three science
instruments and ten technology experiments. The mission operated for three months and returned
2.3 Gbits of data, including over 16,500...
Transition metal oxides are an important class of materials for the wide variety optical, electrical, dielectric, magnetic, and thermal properties observed. Their unique structure-property relationships allow for property tuning and often provide insight into the fundamentals of chemistry. The work in this thesis was focused on the design, synthesis and...
Past measurements off the coast of central Oregon and Washington have shown that the rapid change
from northward monthly mean winter winds to southward summer winds forces a "spring transition" of
the coastal ocean: sea levels and temperatures drop, and mean surface currents shift from northward to
southward. Current and...
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...
