Transport of the copepod, Calanus finmarchicus, in the northwest Atlantic during diapause

Creator:: Kowalke, Gregory L.
Abstract:: The copepod Calanus finmarchicus is the most important and biomass dominant mesozooplankter in the temperate-boreal North Atlantic. C. finmarchicus has an overwintering phase, termed diapause, during which it descends to great depths (300-2000m) and is metabolically quiescent for up to ten months. Changes in the currents at depth due to...

Equatorward jets and poleward undercurrents along the eastern boundary of the mid-latitude north Pacific

Creator:: Pierce, Stephen D.
Abstract:: We sharpen our view of an eastern boundary current region during the upwelling season through the analysis of several data sets. We focus on the mesoscale flow field off of northern California, observed during the Coastal Transition Zone (CTZ) experiment of 1988. First, we estimate tidal currents in the region...

The Influence of Lateral Advection on the Residual Estuarine Circulation: A Numerical Modeling Study of the Hudson River Estuary

Creator:: Scully, Malcolm E., Geyer, W. Rockwell, and Lerczak, James A.
Abstract:: In most estuarine systems it is assumed that the dominant along-channel momentum balance is between the integrated pressure gradient and bed stress. Scaling the amplitude of the estuarine circulation based on this balance has been shown to have predictive skill. However, a number of authors recently highlighted important nonlinear processes...

Turbulent mixing in a strongly forced salt wedge estuary

Creator:: Ralston, David K., Geyer, W. Rockwell, Lerczak, James A., and Scully, Malcolm
Abstract:: Turbulent mixing of salt is examined in a shallow salt wedge estuary with strong fluvial and tidal forcing. A numerical model of the Merrimack River estuary is used to quantify turbulent stress, shear production, and buoyancy flux. Little mixing occurs during flood tides despite strong velocities because bottom boundary layer...

Modeling studies of the coastal circulation off northern California

Creator:: Pullen, Julie D.
Abstract:: By implementing a series of mass-conserving nested high-resolution models down to approximately 1 km resolution that have realistic bathymetry, coastline, wind forcing and river run-off, the winter 1996-1997 shelf flow near Cape Mendocino, California, is simulated and compared with available observations from the Strata Formation on Margins (STRATAFORM) marine geology...

SEASOAR and CTD observations during EBC cruises W9306A and W9308B, June to September 1993

Creator:: Kosro, P. Michael, 1951-, Barth, John A., Fleischbein, Jane, Huyer, Adriana, 1945-, O'Malley, Robert T., Shearman, R. Kipp, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: This report summarizes the Seasoar and CTD observations from Wecoma cruises W9306A (5 June to 12 July, 1993) and W9308B (14 August to 22 September 1993) conducted as part of the Eastern Boundary Currents Accelerated Research Initiative, under funding by the Office of Naval Research. The cruises were designed to...

Phosphorus control of nitrogen fixation

Creator:: Watkins-Brandt, Katie S.
Abstract:: Under conditions of fixed N-limitation, as with most oligotrophic systems, the process of biological N₂ fixation (diazotrophy) is favored, provided the necessary trace elements and vitamins are sufficient. Despite the well understood contributions of N₂ fixation in oligotrophic regions, the nutritional and ecological controls of marine diazotrophs have not been...

Ocean distribution of the American shad (Alosa sapidissima) along the Pacific coast of North America

Creator:: Pearcy, William G. and Fisher, Joseph P.
Abstract:: We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest...

SeaSoar CTD observations from the central Oregon shelf, cruise W9907C : 13-31 July 1999 : a component of the Prediction of Wind-Driven Coastal Circulation Project

Creator:: Barth, John A., O'Malley. R., Erofeev, A. Y., Fleischbein, Jane, Pierce, S. D., and Kosro, P. M.
Abstract:: The primary objectives of R/V Wecoma cruise W9907C were to: 1) collect threedimensional fields of temperature, salinity, and light absorption and attenuation using the towed, undulating vehicle SeaSoar; 2) collect 3-D fields of velocity using shipboard ADCP; 3) to make turbulence profiles along a single cross-shelf transect; and 4) locate,...
