An experimental study on thermal circulation driven by horizontal differential heating
(Cambridge University Press, 2005-09-27)
Circulation driven by horizontal differential heating is studied, using a double-walled Plexiglas tank (20×15×2.5 cm3) filled with salt water. For instances of heating/cooling from above and below, results indicate that ...
Marine reserve effects on fishery profits : a comment on White et al. (2008)
(John Wiley & Sons, 2008-12-22)
A recent study (White et al. 2008) claimed that fishery profits will often be higher with management that employs no-take marine reserves than conventional fisheries management alone. However, this conclusion was based on ...
Enabling long-term oceanographic research : changing data practices, information management strategies and informatics
Interdisciplinary global ocean science requires new ways of thinking about data and data management. With new data policies and growing technological capabilities, datasets of increasing variety and complexity are being ...
Statistics of normal mode amplitudes in an ocean with random sound-speed perturbations : cross-mode coherence and mean intensity
(Acoustical Society of America, 2009-09)
In this paper Creamer's [(1996). J. Acoust. Soc. Am. 99, 2825–2838] transport equation for the mode amplitude coherence matrix resulting from coupled mode propagation through random fields of internal waves is examined in ...
Steroid metabolism in cnidarians : insights from Nematostella vectensis
Cnidarians occupy a key evolutionary position as a sister group to bilaterian animals. While cnidarians contain a diverse complement of steroids, sterols, and other lipid metabolites, relatively little is known of the ...
Monthly variability in upper ocean biogeochemistry due to mesoscale eddy activity in the Saragasso Sea
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-05)
A comparison of monthly biogeochemical measurements made from 1993 to 1995, combined with hydrography and satellite altimetry, was used to observe the impacts of nine eddy events on primary productivity and particle flux ...
Benthic foraminifera living in Gulf of Mexico bathyal and abyssal sediments : community analysis and comparison to metazoan meiofaunal biomass and density
Benthic foraminiferal biomass, density, and species composition were determined at ten sites in the Gulf of Mexico. During June 2001 and June 2002, sediment samples were collected with a GoMex boxcorer. A 7.5-cm diameter ...
Comparison of upwelling indices off Baja California derived from three different wind data sources
(California Cooperative Oceanic Fisheries Investigations, 2007-12)
We compared the NOAA Southwest Fisheries Science Center’s Environmental Research Division (formerly Pacific Fisheries Environmental Laboratory: PFEL) coastal upwelling indices along the northern Baja California coast ...
Distributed space–time cooperative schemes for underwater acoustic communications
In resource limited, large scale underwater sensor networks, cooperative communication over multiple hops offers opportunities to save power. Intermediate nodes between source and destination act as cooperative relays. ...
Coastal Ocean Processes program : advancing interdisciplinary research and technology development
