Geophysical fluid dynamics : notes on the 1960 Summer Study Program in Geophysical Fluid Dynamics at the Woods Hole Oceanographic Institution
(Woods Hole Oceanographic Institution, 1960)
Mid-water current aided localization for autonomous underwater vehicles
Survey-class Autonomous Underwater Vehi- cles (AUVs) typically rely on Doppler Velocity Logs (DVL) for precision localization near the seafloor. In cases where the seafloor depth is greater than the DVL bottom-lock ...
Long-baseline acoustic navigation for under-ice autonomous underwater vehicle operations
The recent Arctic GAkkel Vents Expedition (AGAVE) to the Arctic Ocean’s Gakkel Ridge (July/August 2007) aboard the Swedish ice-breaker I/B Oden employed autonomous underwater vehicles (AUVs) for water-column and ocean ...
Transport of organic carbon from the California coast to the slope region : a study of Δ14C and δ13C signatures of organic compound classes
(American Geophysical Union, 2005-05-05)
Surface sediments along a transect from an abyssal site in the northeastern Pacific (Station M, 34°50′N, 123°00′W) to a small mountainous river on the California coast (Santa Clara River) were studied to investigate the ...
A method for inverting ratio–ratio data to estimate end-member compositions in mixing problems
I discuss the general problem of fitting mixing models to ratio-ratio data, and derive formulae for applying non-linear Maximum Likelihood methods for parameter estimation. To estimate mixing model parameters in the ...
Estimating oceanic turbulence dissipation from seismic images
(American Meteorological Society, 2013-08)
Seismic images of oceanic thermohaline finestructure record vertical displacements from internal waves and turbulence over large sections at unprecedented horizontal resolution. Where reflections follow isopycnals, their ...
Calibration and application of B/Ca, Cd/Ca, and δ11B in Neogloboquadrina pachyderma (sinistral) to constrain CO2 uptake in the subpolar North Atlantic during the last deglaciation
(John Wiley & Sons, 2013-05-30)
The North Atlantic and Norwegian Sea are prominent sinks of atmospheric CO2 today, but their roles in the past remain poorly constrained. In this study, we attempt to use B/Ca and δ11B ratios in the planktonic foraminifera ...
Science under sail : ocean science education program combines traditional vessels with state-of-the-art technology
(Oceanography Society, 2004-09)
Sea Education Association (SEA), located in Woods Hole, Massachusetts, offers introductory oceanographic instruction in the classroom and hands-on research training at sea to create a unique educational experience for ...
Geochemical tracers of extraterrestrial matter in sediments
Every year, tens of thousands of tons of cosmic dust accumulate at the Earth’s surface, representing a continuation of the accretion process that started 4.57 billion years ago. The unique geochemical properties of these ...
Sulfide geochronology along the Endeavour Segment of the Juan de Fuca Ridge
(John Wiley & Sons, 2013-07-08)
Forty-nine hydrothermal sulfide-sulfate rock samples from the Endeavour Segment of the Juan de Fuca Ridge, northeastern Pacific Ocean, were dated by measuring the decay of 226Ra (half-life of 1600 years) in hydrothermal ...
