The cobalt cycle in the Tropical Pacific Ocean
… thesis investigates the geochemical controls on oceanic cobalt scarcity and their biological consequences. Analysis of over 1000 samples collected in the Tropical Pacific Ocean reveals a dissolved cobalt distribution that is strongly coupled to dissolved oxygen, with peak concentrations where …

Monthly mean vertical motions over the Pacific Ocean
… year, (2) the occurrence of the eastern South Pacific intertropical maximum cloud band about 5 degrees away from the equator only in spring, and (3) the curved band of clouds in the western South Pacific.

Bioavailable Iron in Equatorial Pacific Ocean Aerosol Samples
Oceanic iron (Fe) fertilization experiments performed in remote regions have established that Fe additions draw carbon into the ocean, at least over the months-long time frame of the experiments. However, the mechanisms that control Fe speciation in atmospheric aerosol particles before and after …

Selenium Distribution and Cycling in the Eastern Equatorial Pacific Ocean
<p>Oxygen minimum zones in oceanic waters have become increasingly important to the marine environment and society. Low oxygen waters affect not only the distribution and abundance of marine organisms, but also impact the solubility and transport of trace elements that are of biological importance, …

Cloud effects on ocean mixed layer in the northeast Pacific Ocean.
… to examine the effects of clouds on the ocean mixed layer, both short-term and seasonal. It utilized data collected at Ocean Station Papa in the northeast Pacific. Two numerical modeling simulations were performed (i.e., with variable cloud and with variable precipitation). The results …

An estimate of the upwelling rate in the tropical Pacific Ocean
An inverse box model of the tropical Pacific Ocean from 321S - 10N is constructed from two zonal and six meridional hydrographic sections. This data is supplemented with LADCP data close to the equator where geostrophy fails. A consistent solution is found despite the presence of a number of …

Mechanisms of heat transport through the floor of the equatorial Pacific Ocean
The equatorial Pacific heat flow low, a major oceanic geothermal anomaly centered on the equatorial sediment bulge, was investigated using deeply penetrating heat flow probes (6-11 meters penetration) within three detailed surveys (400 km2) and along over 10,000 km of continuous seismic profiles …

Rare metal resources in polymetallic nodules from the Eastern Equatorial Pacific Ocean
… fracture zone (CCFZ) in the eastern equatorial Pacific is the area with the greatest interest in terms of metal resources in polymetallic nodules. The nodules are enriched (relative to crustal composition) in economically important metals such as Mn, Ni, Cu, Zn, and so-called critical metals …

Evaluation of GEOSAT data and application to variability of the Northeast Pacific Ocean
A portion of the northeast Pacific ocean was chosen within which to evaluate and use altimetric data from the U.S. Navy Geodetic Satellite GEOSAT. The zero-order accuracy of the major GEOSAT geophysical data record (GDR) channels was verified, and occasional gaps in the altimeter coverage were …

Understanding the CO₂cycle in the North Pacific Ocean using inverse box models
… able to close the tracer budgets in the North Pacific than the Levitus section. The transport calculations showed that highly resolved hydrographic data are necessary to accurately determine the tracer transports, and pointed out the sensitivity of the calculation to errors in the Ekman …
