A Child's View of Circulation in Prince William Sound, Alaska?
Prince William Sound Circulation
2015/7/20
An oceanographic field exercise was conducted in central Prince William Sound, Alaska, in mid summer 2004 to evaluate the capability of the Prince William Sound Observing System to forecast the trajec...
Identifying variable sea ice carbon contributions to the Arctic ecosystem: A case study using highly branched isoprenoid lipid biomarkers in Cumberland Sound ringed seals
Sea ice carbon The arctic ecosystem
2014/10/16
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast
Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it’s a major factor just a little farther out into Rhode Island Sound. Scientis...
Scientists Identify Source of Mysterious Low-Frequency Sound Heard for Decades in the Southern Ocean
Scientists Identify Source Mysterious Low-Frequency Sound Heard for Decades Southern Ocean
2014/5/13
Scientists have conclusive evidence that the source of a unique rhythmic sound, recorded for decades in the Southern Ocean and called the “bio-duck,” is the Antarctic minke whale (Balaenoptera bonaere...
Simulating Underwater Plasma Sound Sources to Evaluate Focusing Performance and Analyze Errors
underwater plasma sound source focusing sound field error analysis 3D Max
2011/9/9
Focused underwater plasma sound sources are being applied in more and more fields. Focusing performance is one of the most important factors determining transmission distance and peak values of the pu...
Ocean Acidification and the Increasing Transparency of the Ocean to Low-Frequency Sound
Ocean acid boric acid to dissolve carbonate ions sound waves Marine mammals
2015/7/6
As the ocean becomes more acidic, low-frequency (~ 1–3 kHz and below) sound travels much farther due to changes in the amounts of pH-dependent species such as dissolved borate and carbonate ions, whic...

Bispectra and Cross-Bispectra of Temperature, Salinity, Sound Velocity and Density Fluctuations with Depth off Northeastern Japan
Temperature Salinity Sound Velocity Density Fluctuations
2009/4/2
Off northeastern Japan, depth profiles of temperature, salinity, sound velocity and density show considerable structure between 30 and 240 m. The structure is asymmetric with respect to the mean and t...
On North Pacific Temperature, Salinity, Sound Velocity and Density Fronts and their Relation to the Wind and Energy Flux Fields
North Pacific Temperature Sound Velocity Salinity Density Fronts Energy Flux Fields
2009/3/24
The main oceanic fronts of the North Pacific are investigated and the principal frontogenetic processes described. Fronts are features of the upper ocean and occur near mass transport and energy flux ...
The Depth Variability of Meridional Gradients of Temperature, Salinity and Sound Velocity in the Western North Pacific
Meridional Gradients Temperature Salinity Sound Velocity
2009/2/13
In the western North Pacific, meridional gradients of temperature, salinity and sound velocity show considerable variation with depth. Gradients of frontal intensity (more than three times the rms val...
Mesoscale Thermohaline, Sound Velocity and Baroclinic Flow Structure of the Pacific Subtropical Front During the Winter of 1980
Mesoscale Thermohaline Sound Velocity Baroclinic Flow
2009/2/9
The three-dimensional thermohaline. sound velocity and baroclinic flow structure of the. pacific sub-tropical front during January and February 1990 are discussed. The front is meander-like, with a wa...
Scattering of Sound by Internal Wave Currents：The Relation to Vertical Momentum Flux
Internal Wave Currents Vertical Momentum Flux
2009/2/9
Internal waves scatter sound by two related perturbations: 1) those associated with vertical particle displacements (x, y, z, t) in the presence of a vertical gradient of (potential) sound speed (δc =...
