Above and Below : Oregon Coastal Phytoplankton Bloom Dynamics from Sea and Space

Creator:: McKibben, S. Morgaine
Abstract:: Phytoplankton are a sentinel class of organisms in the marine environment. Through their photosynthetic activity in sunlit waters worldwide, phytoplankton shape the health and productivity of marine ecosystems and impact the global climate. In this work a range of ocean sensing technologies (via ships, surf zone sampling, moorings, gliders, and...

Some possible roles for selenium in the reproductive physiology of the male graytailed vole (Microtus canicaudus)

Creator:: Whitfield, Stephen Curtiss
Abstract:: The testes of the gray-tailed vole (Microtus canicaudus Miller) exhibited a high affinity for selenium relative to other selected tissues. Uptake of selenium-75 in the testis-epididymis complex was delayed relative to uptake by the whole body, kidney, and liver. This pattern of uptake suggested that selenium was metabolically incorporated into...

Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

Creator:: Kavanaugh, Maria T.
Abstract:: Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

Vicarious calibration of the Ocean PHILLS hyperspectral sensor using a coastal tree-shadow method

Creator:: Filippi, Anthony M., Carder, Kendall L., and Davis, Curtiss O.
Abstract:: Ocean color remote-sensing systems require highly accurate calibration (<0.5%) for accurate retrieval of water properties. This accuracy is typically achieved by vicarious calibration which is done by comparing the atmospherically corrected remote-sensing data to accurate estimates of the water-leaving radiance. Here we present a new method for vicarious calibration of...

Atmospheric Correction Algorithm for Hyperspectral Remote Sensing of Ocean Color from Space

Creator:: Gao, Bo-Cai, Montes, Marcos J., Ahmad, Ziauddin, and Davis, Curtiss O.
Abstract:: Existing atmospheric correction algorithms for multichannel remote sensing of ocean color from space were designed for retrieving water-leaving radiances in the visible over clear deep ocean areas and cannot easily be modified for retrievals over turbid coastal waters. We have developed an atmospheric correction algorithm for hyperspectral remote sensing of...

Assessment of new production at the upwelling center at Point Conception, California, using nitrate estimated from remotely sensed sea surface temperature

Creator:: Dugdale, Richard C., Davis, Curtiss O., and Wilkerson, Frances P.
Abstract:: Remotely sensed sea surface temperature (SST) and a model originally developed for Cap Blanc, northwest Africa [Dugdale et al., 1989], are used to estimate new production (i.e., nitrate uptake, in the sense of Dugdale and Goering [1967]) for the persistent coastal upwelling feature at Point Conception, California. Parameters required to...

Surface Heating and Patchiness in the Coastal Ocean off Central California During a Wind Relaxation Event

Creator:: Ramp, Steven R., Garwood, Roland W., Davis, Curtiss O., and Snow, Richard L.
Abstract:: The difference between the temperature of the ocean at 4-cm and 2-m depth was continuously monitored during a cruise to the coastal transition zone off Point Arena, California (38°58′N, 123°45′W), during June 1987. The two temperatures were coincident most of the time but diverged during one nearshore leg of the...

Analysis of a Point-Source Integrating-Cavity Absorption Meter

Creator:: Leathers, Robert A., Downes, T. Valerie, and Davis, Curtiss O.
Abstract:: We evaluate the theoretical performance of a point-source integrating-cavity absorption meter (PSICAM) with Monte Carlo simulations and a sensitivity analysis. We quantify the scattering errors, verifying that they are negligible for most ocean optics applications. Although the PSICAM detector response is highly sensitive to the value of the wall reflectivity,...

Photosynthetic Characteristics and Estimated Growth Rates Indicate Grazing Is the Proximate Control of Primary Production in the Equatorial Pacific

Creator:: Cullen, John J., Lewis, Marlon R., Davis, Curtiss O., and Barber, Richard T.
Abstract:: Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited; the nature of this limitation has yet to be resolved. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the control of primary productivity, a question of great biogeochemical...
