How the oceanographic community created a National Oceanographic Partnership Program
(Oceanography Society, 2009-06)
On this tenth anniversary of the National Oceanographic Partnership Program, and as our nation embarks on a broad set of critical societal initiatives, it is valuable to review the accomplishments of the program, and ...
An estimate of the global distribution of radon emissions from the ocean
(American Geophysical Union, 2004-10-07)
There is a need for improved estimates of the radon (222Rn) flux density from the ocean for use in the modeling and interpretation of atmospheric radon in global climate and air pollution studies. We use a modification of ...
Coastline responses to changing storm patterns
(American Geophysical Union, 2006-09-20)
Researchers and coastal managers are pondering how accelerated sea-level rise and possibly intensified storms will affect shorelines. These issues are most often investigated in a cross-shore profile framework, fostering ...
Detection of an unusually large hydrothermal event plume above the slow-spreading Carlsberg Ridge : NW Indian Ocean
(American Geophysical Union, 2006-05-31)
About 90% of Earth's volcanism occurs along the global mid-ocean ridge system. Here, sporadic volcanic and tectonic activity is thought to cause cataclysmic release of hydrothermal fluids, forming event plumes. Each plume ...
CO2 deposition over the multi-year ice of the western Weddell Sea
(American Geophysical Union, 2006-07-13)
Field measurements by eddy correlation (EC) indicate an average uptake of 0.6 g CO2 m−2 d−1 by the ice-covered western Weddell Sea in December 2004. At the same time, snow that covers ice floes of the western Weddell Sea ...
Observation of very large and steep internal waves of elevation near the Massachusetts coast
(American Geophysical Union, 2004-11-25)
We report on near-bottom waves of elevation with amplitude nearly half the 25 m water column, very steep, and propagating into a sheared turbulent wave-guide. The waves contained trapped cores transporting parcels of water ...
Unraveling the sequence of serpentinization reactions : petrography, mineral chemistry, and petrophysics of serpentinites from MAR 15°N (ODP Leg 209, Site 1274)
(American Geophysical Union, 2006-07-06)
The results of detailed textural, mineral chemical, and petrophysical studies shed new light on the poorly constrained fluid-rock reaction pathways during retrograde serpentinization at mid-ocean ridges. Uniformly depleted ...
Comment on “Modern-age buildup of CO2 and its effects on seawater acidity and salinity” by Hugo A. Loáiciga
(American Geophysical Union, 2007-09-25)
Electrical structure beneath the northern MELT line on the East Pacific Rise at 15°45′S
(American Geophysical Union, 2006-11-16)
The electrical structure of the upper mantle beneath the East Pacific Rise (EPR) at 15°45′S is imaged by inverting seafloor magnetotelluric data obtained during the Mantle ELectromagnetic and Tomography (MELT) experiment. ...
Seismic reflection imaging of water mass boundaries in the Norwegian Sea
(American Geophysical Union, 2004-12-14)
Results from the first joint temperature and seismic reflection study of the ocean demonstrate that water mass boundaries can be acoustically mapped. Multichannel seismic profiles collected in the Norwegian Sea show ...
