Creator:: Smyth, William D., Hebert, D., and Moum, James N.
Abstract:: A westerly wind burst observed in the warm pool of the western equatorial Pacific Ocean cooled the ocean's surface layer by about 0.8°C. Turbulent entrainment at the base of this layer caused cooling but also heating due to the reversal of the vertical temperature gradient during rain events. Consequently, the...

Abstract:: The dynamic response to a westerly wind burst which occurred during the Couple Ocean Atmosphere Response Experiment in the warm pool of the equatorial Pacific Ocean is described using velocity, hydrography, and microstructure measurements. Turbulent fluxes distributed momentum input from the wind over a near-surface layer of variable thickness. Coriolis...

Abstract:: Suspended matter in Astoria canyon was monitored by means of an in situ nephelometer and by means of light-scattering and particle concentration measurements performed aboard ship on water samples. Nephelometer profiles obtained along the axis of the canyon in February and April 1973 indicate that the canyon is divided into...

Abstract:: The role of stratified shear instability in maintaining the deep cycle of turbulence immediately below the equatorial mixed layer is examined by means of linear stability analysis. The Taylor-Goldstein equation is solved numerically, using observed currents and stratification from the Tropical Instability Wave Experiment (TIWE). Multiple unstable modes are found,...

Abstract:: Optical and hydrographic observations were made at two meridional sections across the Cromwell Current at 92°00’ and 91°40’W during February 1969. The distribution of hydrographic and optical properties near the Galapagos Islands is described. Beneath the thermocline the Cromwell Current is characterized by deepening of the light-scattering isolines. Above the...

Abstract:: The island of Tahiti, the largest in French Polynesia, comprises two major volcanoes aligned NW-SE, parallel with the general trend of the Society Islands hotspot track. Rocks form this volcanic system are basalts transitional to tholeiites, alkali basalts, basanites, picrites, and evolved lavas. Through K-Ar radiometric dating we have established...

Creator:: Twohy, Cynthia, Coakley, James A. Jr., and Tahnk, William R.
Abstract:: Many investigations using satellite data have determined that aerosol optical depth and cloud cover are correlated and some have interpreted the correlation as evidence of an aerosol indirect effect on clouds. This study uses in situ aircraft observations taken during the Indian Ocean Experiment (INDOEX), February–March 1999, and mostly over...

Abstract:: The distribution of suspended matter in the Panama basin was determined by means of light scattering and Coulter counter measurements on water samples collected at 50 hydrographic stations. The observed distribution indicates three probable sources of suspended matter: (1) the surface waters throughout the basin; (2) erosion and runoff from...

Creator:: White, William M., McBirney, Alexander R., and Duncan, Robert A.
Abstract:: We report new major element, trace element, isotope ratio, and geochronological data on the Galapagos Archipelago. Magmas erupted from the large western volcanos are generally moderately fractionated tholeiites of uniform composition; those erupted on other islands are compositionally diverse, ranging from tholeiites to picritic basanitoids. While these volcanoes do not...

Abstract:: Hydrographic and tracer data from 2002 illustrate Atlantic water pathways and variability in the Mendeleev Ridge and Chukchi Borderland (CBLMR) region of the Arctic Ocean. Thermohaline double diffusive intrusions (zigzags) dominate both the Fram Strait (FSBW) and Barents Sea Branch Waters (BSBW) in the region. We show that details of...
