Estimation of Time Averages from Irregularly Spaced Observations: With Application to Coastal Zone Color Scanner Estimates of Chlorophyll Concentration

Creator:: Chelton, Dudley B. and Schlax, Michael C.
Abstract:: A formalism is presented for quantifying the sampling error of an arbitrary linear estimate of a time-averaged quantity constructed from a time series of irregularly spaced observations at a fixed location. The method is applicable to any irregularly sampled time series; it is applied here to satellite observations of chlorophyll...

Ocean circulation and properties in Petermann Fjord, Greenland

Creator:: Johnson, H. L., Münchow, A., Falkner, K. K., and Melling, H.
Abstract:: The floating ice shelf of Petermann glacier interacts directly with the ocean and is thought to lose at least 80% of its mass through basal melting. Based on three opportunistic ocean surveys in Petermann Fjord we describe the basic oceanography: the circulation at the fjord mouth, the hydrographic structure beneath...

Seasonal renewal of the California Current: The spring transition off California

Creator:: Lynn, Ronald J., Bograd, Steven J., Chereskin, Teresa K., and Huyer, Adriana, 1945-
Abstract:: A pair of high-resolution oceanographic surveys in March and April 1995 revealed a large and rapid transition from late winter to spring conditions in the coastal zone off central and southern California. These data are unique in capturing the detailed three-dimensional physical structure of and biological response to the spring...

Time Evolution of Surface Chlorophyll Patterns From Cross-Spectrum Analysis of Satellite Color Images

Creator:: Denman, Kenneth L. and Abbott, Mark R.
Abstract:: Sequences of coastal zone color scanner (CZCS) images from the offshore region adjacent to Vancouver Island, Canada, have been analyzed to estimate the time rate of decorrelation of surface phytoplankton chlorophyll pigment patterns. In these high-latitude, high-pigment areas, CZCS-derived pigment estimates were lower than those obtained from ship samples by...

Estimation of surface winds from upward looking acoustic doppler current profilers

Creator:: Brown, J., Barton, E.D., Trasvina, A., Velez, H.S., Kosro, P. Michael, 1951-, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: Three upward looking acoustic Doppler current profilers (ADCP) were deployed beneath meteorological buoys in the Gulf of Tehuantepec, Mexico, during winter 1988-1989. Hourly averaged wind speed data from the buoys and from ship when in the vicinity were compared with surface acoustic backscatter intensity recorded at the ADCPs. The backscatter...

Chlorophyll enchancement and mixing associated with meanders of the shelf break front in the Mid-Atlantic Bight

Creator:: Ryan, J. P., Yoder, J. A., Barth, John A., and Cornillon, P. C.
Abstract:: Meanders of the shelf break front in the Mid-Atlantic Bight (MAB) during April and May of 1997 were associated with chlorophyll enhancement along a hydrographic and a topographic feature. The hydrographic feature was the surface outcrop of the front, which ranged from ~10 to >100 km seaward of the shelf...

Horizontal transport and the distribution of nutrients in the coastal transition zone off Northern California: effects on primary production, phytoplankton biomass and species composition

Creator:: Chavez, Francisco P., Barber, Richard T., Kosro, P. Michael, 1951-, Huyer, Adriana, 1945-, Ramp, Steven R., Stanton, Timothy P., and Rojas de Mendiola, Blanca
Abstract:: Conductivity‐temperature‐depth surveys during 1988 encountered strong baroclinic jets that were evident in acoustic Doppler current profiler and hydrographic data. During June and July 1988 a filament with high surface nitrate, high chlorophyll, abundant populations of neritic centric diatoms, and higher rates of primary production was evident perpendicular to the coast...

Poleward propagating subinertial alongshore surface currents off the U.S. West Coast

Creator:: Kim, Sung Yong, Cornuelle, Bruce D., Terrill, Eric J., Jones, Burt, Washburn, Libe, Moline, Mark A., Paduan, Jeffrey D., Garfield, Newell, Largier, John L., Crawford, Greg, and Kosro, P. Michael
Abstract:: The network comprising 61 high-frequency radar systems along the U.S. West Coast (USWC) provides a unique, high resolution, and broad scale view of ocean surface circulation. Subinertial alongshore surface currents show poleward propagating signals with phase speeds of O(10) and O(100–300) km d⁻¹ that are consistent with historical in situ...

Offshore wind forcing in the Gulf of Tehuantepec, Mexico: the asymmetric circulation

Creator:: Trasviña, A., Barton, E.D., Brown, J., Velez, H.S., Kosro, P. Michael, 1951-, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: Since the early surveys carried out by the Eastern Tropical Pacific (EASTROPIC) and Scripps Tuna Oceanographic Research (STOR) projects in the tropical Pacific off Mexico, the northerly winds which blow over the Gulf of Tehuantepec were described as an Important factor controlling the dynamics of this coastal ocean. In January-February...

Evolution of 1996-1999 La Niña and El Niño conditions off the western coast of South America: A remote sensing perspective

Creator:: Carr, Mary-Elena, Strub, P. Ted, Thomas, Andrew C., and Blanco, Jose Luis
Abstract:: We present the evolution of oceanographic conditions off the western coast of South America between 1996 and 1999, including the cold periods of 1996 and 1998–1999 and the 1997–1998 El Niño, using satellite observations of sea level, winds, sea surface temperature (SST), and chlorophyll concentration. Following a period of cold...
