Thermohaline interleaving is an important mechanism for laterally fluxing salt, heat,
and nutrients between oceanic water masses. Interleaving is driven by a release of potential energy resulting from the vastly differing diffusivities of heat and...

To date, the use of oceanographic data in fisheries management has been limited by
the scarcity and the difficulty of accessing complete oceanographic datasets.
Consequently, fish stocks are managed with limited knowledge about the habitat where...

An analytical model of subtropical mode water is presented, based on ventilated thermocline
theory and on numerical solutions of a planetary geostrophic basin model. In ventilated
thermocline theory, the western pool is a region bounded on the...

Remote areas are frequently homes to regional subpopulations of endangered green
sea turtles (Chelonia mydas) and their essential habitat. Local communities are often
the users and primary stewards of this valuable and charismatic resource....

Large barite (BaSO4) structures mark cold seeps in the southern San Clemente
Basin. Barium flux to San Clemente sediments is two to three times greater than fluxes
measured in surrounding California Borderland basins. Analyses of sediment trap...

Experiments were designed to answer key questions about diatom-derived organic
matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom...

Our view of phytoplankton has historically revolved around their inability to
control their location in space. The term phytoplankton itself underscores this
particular difference between phytoplankton and their sessile terrestrial counterparts....

Plate boundaries are commonly regions of complex, diffuse deformation with
the motion across the boundary accommodated by numerous structural systems, rather
than being narrow, discrete zones of deformation. One such boundary occurs where
the...

This thesis examines the mechanisms that couple the monthly-averaged
atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST)
perturbations on scales of 50-500 km. The observed positive correlation between
surface wind speed...
