Sound Cut, Record Number 9101301k
(Woods Hole Oceanographic Institution, 2003-06-10)
Recording of ten or more Fraser’s dolphins made by Ithaco 602M108 hydrophones, Ithaco 451 amplifiers, WHOI/PEMTEK tape recorder. Good clicks and whistles. Feeding at surface.
Sound Cut, Record Number 6702700C
(Woods Hole Oceanographic Institution, 1992-04-30)
Recording of 2 Ribbon seals. One downsweep and an in-air growl.
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 ...
Dynamic intermediate ocean circulation in the North Atlantic during Heinrich Stadial 1 : a radiocarbon and neodymium isotope perspective
(John Wiley & Sons, 2014-11-20)
The last deglaciation was characterized by a series of millennial-scale climate events that have been linked to deep ocean variability. While often implied in interpretations, few direct constraints exist on circulation ...
Towards improved socio-economic assessments of ocean acidification’s impacts
Ocean acidification is increasingly recognized as a component of global change that could have a wide range of impacts on marine organisms, the ecosystems they live in, and the goods and services they provide humankind. ...
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 ...
Universal structure of mesoscale eddies in the ocean
(John Wiley & Sons, 2013-07-30)
Mesoscale eddies dominate oceanic kinetic energy at sub-inertial frequencies. Their three-dimensional structure has, however, remained obscure, hindering better understanding of eddy dynamics. Here by applying the composite ...
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 ...
Airborne-radar and ice-core observations of annual snow accumulation over Thwaites Glacier, West Antarctica confirm the spatiotemporal variability of global and regional atmospheric models
(John Wiley & Sons, 2013-07-26)
We use an airborne-radar method, verified with ice-core accumulation records, to determine the spatiotemporal variations of snow accumulation over Thwaites Glacier, West Antarctica between 1980 and 2009. We also present a ...
Active positioning of vent larvae at a mid-ocean ridge
The vertical position of larvae of vent species above a mid-ocean ridge potentially has a strong effect on their dispersal. Larvae may be advected upward in the buoyant vent plume, or move as a consequence of their buoyancy ...
