Age systematics of two young en echelon Samoan volcanic trails
(American Geophysical Union, 2011-07-29)
The volcanic origin of the Samoan archipelago can be explained by one of three models, specifically, by a hot spot forming over a mantle plume, by lithospheric extension resulting from complex subduction tectonics in the ...
Molecular characterization of dissolved organic matter associated with the Greenland ice sheet
Subsurface microbial oxidation of overridden soils and vegetation beneath glaciers and ice sheets may affect global carbon budgets on glacial-interglacial timescales. The likelihood and magnitude of this process depends ...
Timescales of magmatic processes and eruption ages of the Nyiragongo volcanics from 238U-230Th-226Ra-210Pb disequilibria
The silica-undersaturated Nyiragongo volcanics, located in the East African rift, have globally unique chemical compositions and unusually low viscosities, only higher than carbonatite lavas, for terrestrial silicate ...
Extracting wind sea and swell from directional wave spectra derived from a bottom-mounted ADCP
(Woods Hole Oceanographic Institution, 2006-07)
Recent advances in processing velocity data from bottom-mounted Acoustic Doppler Current Profilers (ADCPs) offer the capability of partitioning directional wave specctra of surface wave height in order to separate locally ...
Preliminary examination of the low-frequency ambient noise field in the South China Sea during the 2001 ASIAEX experiment
This correspondence presents a preliminary examination of the low frequency ambient noise field measured in the South China Sea component of the Asian Seas International Acoustics Experiment (ASIAEX), concentrating on the ...
Observations of wave-mean flow interaction in the Pacific Equatorial Undercurrent
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1990-09)
The contribution of tropical instability waves to the momentum and energy balances of the Pacific Equatorial Undercurrent is investigated using velocity and temperature time series from the three-dimensional Equatorial Pacific ...
Vertical distribution of temperature and humidity over the Caribbean Sea
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1949)
The observations presented and discussed in this paper were obtained as part of a research project conducted under contract NObs-2083 with the Bureau of Ships of the U. S. Navy by the Woods Hole Oceanographic Institution. ...
Postprocessing system for echo sounder data
(Acoustical Society of America, 1991-07)
Echo sounding is a powerful and widely used technique for remote sensing of the marine environment. In order to enhance the power of the echo sounder, a postprocessing system has been designed and realized in standard ...
Deep-sea mining of seafloor massive sulfides
The potential emergence of an ocean mining industry to exploit seafloor massive sulfides could present opportunities for oceanographic science to facilitate seafloor mineral development in ways that lessen environmental harms.
Near-inertial and thermal upper ocean response to atmospheric forcing in the North Atlantic Ocean
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2010-06)
Observational and modeling techniques are employed to investigate the thermal and inertial upper ocean response to wind and buoyancy forcing in the North Atlantic Ocean. First, the seasonal kinetic energy variability of ...
