Creator:: Hales, Burke, Hebert, Dave, and Marra, John
Abstract:: We present observations from deployments of a microstructure turbulence instrument (the Towed Microstructure and Auxiliary Sensor Instrument) aboard a pumping profiling vehicle (the Lamont Pumping SeaSoar) towed behind a research vessel at the New England shelf break front in August 2002. From these we determined coincident fine-scale vertical eddy diffusivity...

Abstract:: During March–April 1999, 2 weeks of undulating CTD and shipboard acoustic Doppler current profiler surveys revealed the variability of the intense internal tide on the northern edge of Georges Bank. The nature of the internal tide was modulated by episodic surface intrusions of cool, fresh Scotian Shelf Water (SSW), stratifying...

Creator:: Nielsen, Roger L.
Abstract:: Utilizing a phase equilibria based trace element isotope model for low pressure igneous differentiation, it is now possible to update the methods presently being used to evaluate the effect of assimilation and fractional crystallization (AFC) processes. The results of the calculations presented here indicate that bulk partition coefficients (D) for...

Abstract:: Repeated conductivity, temperature, and depth (CTD) sections were made across the continental margin off Peru at 5°S and 10°S between November 1981 and May 1984, i.e., before, during, and after El Nino of 1982-1983. Coastal sea level at Paita (5°S) and Callao (12°S) began to rise in early October 1982...

Creator:: Beaudoin, Bruce C., Hole, John A., Klemperer, Simon L., and Tréhu, Anne Martine
Abstract:: As the Mendocino Triple Junction migrates northward along the California margin it is widely presumed to leave a "slab-free" or "asthenospheric" window in its wake. A 250-km-long south-north seismic refraction-reflection profile crossing the transition from transform to subduction regimes allows us to compare and contrast crust and upper mantle of...

Abstract:: Using the counterflow virtual impactor, a new instrument for sampling cloud droplets, measurable levels of light-absorbing material were found to exist inside droplets in stratocumulus clouds off the coast of southern California. Eighty percent of the samples of droplet residue material had light absorption coefficients ranging from 6 to 20...

Abstract:: In November-December 1984 we carried out an intensive 12-day upper ocean sampling program on the equator at 140°W as part of the Tropic Heat Experiment. From our observations we constructed hourly averaged profiles of temperature, salinity, σ₁, turbulent kinetic energy dissipation rate, and horizontal velocity. These data were used to...

Abstract:: Light transmission profiles have been used to study the optical properties of the suspended particles which are characteristic of the area of the Scotian Rise in the North Atlantic Ocean. This area is typified by very strong bottom currents and a highly variable bedform morphology. A good correlation (r =...

Abstract:: Profiles of light transmission versus depth have been studied in the region of the Scotian Rise of the North Atlantic at bottom depths between 4900 and 5000 m. A component model has been developed and consists of three components of transmission which can be combined to duplicate accurately any given...

Abstract:: Repeated microstructure transects across filaments in the coastal transition zone (CTZ) have Revealed fundamental structure and dynamics of the complicated features. The measurements allow detailed momentum and vorticity analyses and provide a possible explanations for structural asymmetry of the fronts. Observations made between July 2 and July 23, 1988, along...
