Fine-scale variability at 140°W in the Equatorial Pacific

Creator:: Chereskin, T. K., Moum, James N., Stabeno, P. J., Caldwell, Douglas R., Paulson, C. A., Regier, L. A., and Halpern, D.
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...

Primary Production Estimates from Recordings of Solar-Stimulated Fluorescence in the Equatorial Pacific at 150°W

Creator:: Stegmann, P. M., Lewis, M. R., Davis, C. O., and Cullen, J. J.
Abstract:: Biological, optical, and hydrographical data were collected on the WEC88 cruise along 150°W and during a 6-day time series station on the equator during February/March 1988. This area was characterized by a subsurface chlorophyll maximum (SCM), located at 50–70 m depth at the equator and descending down to 120–125 m...

Optical and hydrographic observations of the Cromwell Current between 92°00'W and the Galapagos Islands

Creator:: Zaneveld, J. Ronald, Pak, Hasong, and Plank, William S.
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...

Initiation of the spring phytoplankton increase in the Antarctic Polar Front Zone at 170°W

Creator:: Landry, Michael R., Brown, Susan L., Selph, Karen E., Abbott, Mark R., Letelier, Ricardo M., Christensen, Stephanie, Bidigare, Robert R., and Casciotti, K.
Abstract:: During austral summer 1997, satellite imagery revealed enhanced chlorophyll associated with the Antarctic Polar Front at 170°W. Phytoplankton growth conditions during the early stages of the spring increase were investigated on the Antarctic Environment and Southern Ocean Process Study Survey I cruise using flow cytometry (FCM) and microscopy to characterize...

Mesoscale physical and bio-optical structure of the Antarctic Polar Front near 170°W during austral spring

Creator:: Barth, John A., Cowles, Timothy J., and Pierce, Stephen D.
Abstract:: As part of the U.S. Joint Global Ocean Flux Study Southern Ocean program, high-resolution surveys of the Antarctic Polar Front near 170øW were conducted during October-November 1997 with a towed undulating system equipped with conductivity-temperature-depth and bio-optical sensors. Transects along 170°W and two successive mapping surveys revealed zonal bands with...

TOPEX/POSEIDON tides estimated using a global inverse model

Creator:: Egbert, Gary D., Bennett, Andrew F., and Foreman, Michael G. G.
Abstract:: Altimetric data from the TOPEX/POSEIDON mission will be used for studies of global ocean circulation and marine geophysics. However, it is first necessary to remove the ocean tides, which are aliased in the raw data. The tides are constrained by two distinct types of information: the hydrodynamic equations which the...

Variability of water vapor in the tropical upper troposphere as measured by the Microwave Limb Sounder on UARS

Creator:: Clark, H. L, Harwood, R. S., Mote, Philip W., and Read, W. G.
Abstract:: The Microwave Limb Sounder (MLS), an instrument on the Upper Atmosphere Research Satellite (UARS), measures water vapor in the upper troposphere, with best sensitivity at the standard UARS level at 215 hPa. In this paper, we analyze the MLS observations with a view to characterizing the temporal and zonal variations...

Tracing Pacific water in the North Atlantic Ocean

Creator:: Jones, E. P., Swift, J. H., Anderson, L. G., Lipizer, M., Civitarese, G., Falkner, Kelly, Kattner, G., and McLaughlin, F. A.
Abstract:: In the Arctic Ocean, Pacific source water can be distinguished from Atlantic source water by nitrate-phosphate concentration relationships, with Pacific water having higher phosphate concentrations relative to those of nitrate. Furthermore, Pacific water, originally from the inflow through Bering Strait, is clearly recognizable in the outflows of lowsalinity waters from...

Light-Absorbing Material Extracted From Cloud Droplets and Its Effect on Cloud Albedo

Creator:: Twohy, Cynthia, Clarke, A. D., Warren, S. G., Radke, L. F., and Charlson, R. J.
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...

Data assimilation and bathymetric inversion in a two‐dimensional horizontal surf zone model

Creator:: Wilson, G. W., Özkan-Haller, H. Tuba, and Holman, R. A.
Abstract:: A methodology is described for assimilating observations in a steady state twodimensional horizontal (2‐DH) model of nearshore hydrodynamics (waves and currents), using an ensemble‐based statistical estimator. In this application, we treat bathymetry as a model parameter, which is subject to a specified prior uncertainty. The statistical estimator uses state augmentation...
