Stirring And Mixing Of Thermohaline Anomalies, A. Colin De Verdiere, J. G. Harvey, M. Arhan Jan 1986

Stirring And Mixing Of Thermohaline Anomalies, A. Colin De Verdiere, J. G. Harvey, M. Arhan

Journal of Marine Research

Data from the Tourbillon Experiment in the eastern North Atlantic indicate clearly the stirring of waters with contrasting thermohaline properties by a mesoscale eddy, and the ensuing mixture which occurred. The observed features are discussed in relation to a mixing scenario which considers the salinity distribution in the eastern N. Atlantic associated with the Mediterranean Water (MW) outflow through the Straits of Gibraltar to provide a large-scale context. A mesoscale eddy near the boundary of this water mass advected and deformed a blob of MW, sharpening thermohaline fronts so that double diffusive frontal intrusions developed. Double diffusion processes are invoked …


On The Role Of Topography In The Ocean Circulation, Paola Cessi, Joseph Pedlosky Jan 1986

On The Role Of Topography In The Ocean Circulation, Paola Cessi, Joseph Pedlosky

Journal of Marine Research

The ideas developed by Rhines and Young (1982a,b) are used to analyze the effect of topography in simple baroclinic models. The presence of longitude-dependent topography induces strong internal jets with transports of the same magnitude as the interior flow. It is shown that the existence of these features is independent of the forcing structure at the top of the model ocean, of the topography form and of the forcing in subsurface layers as long as the latter is small. Some examples are given both for forcings which, in the absence of topography, would give circulations closed in the interior and …


A Simplified Linear Ocean Circulation Theory, Rick Salmon Jan 1986

A Simplified Linear Ocean Circulation Theory, Rick Salmon

Journal of Marine Research

The linear theory of the wind- and thermally-driven ocean circulation simplifies considerably if the traditional Laplacian viscosity and thermal diffusivity are replaced by a linear-decay friction and heat diffusion. Solutions of the simplified equations display all the physically important features of the standard model.


Sediment Trap Biases In Turbulent Flows: Results From A Laboratory Flume Study, Cheryl Ann Butman Jan 1986

Sediment Trap Biases In Turbulent Flows: Results From A Laboratory Flume Study, Cheryl Ann Butman

Journal of Marine Research

Several cylindrical and noncylindrical sediment trap designs were tested in a recirculating steady-flow flume. The laboratory study was conducted to achieve dynamic- and geometric-similarity to conditions in a specific field environment where traps eventually would be deployed. Relative (to a "standard" trap design) particle collection efficiencies of the traps were quantified in ∼10 cm/sec turbulent flows that were continuously seeded with particles having fall velocities of about 10−2 to 10−1 cm/sec (the upper range of silt-sized quartz sediments). The nature of flow through the trap mouths was qualitatively described using dye.The following trap biases were demonstrated in the …


Spacial And Temporal Variations Of Water Characteristics In The Japan Sea Bottom Layer, Toshitaka Gomo, Yoshiyuki Nozaki, Hitoshi Sakai, Toshisuke Nakai, Hiroyuki Tsubota Jan 1986

Spacial And Temporal Variations Of Water Characteristics In The Japan Sea Bottom Layer, Toshitaka Gomo, Yoshiyuki Nozaki, Hitoshi Sakai, Toshisuke Nakai, Hiroyuki Tsubota

Journal of Marine Research

The Japan Sea is an almost landlocked marginal sea. We measured profiles of CTD potential temperature at 9 stations in the southeastern Japan Sea to clarify the characteristics of the abyssal circulation in the Sea. It was shown that the results were closely correlated with the topography of the Japan Sea which is characterized by a rise in the center of the Sea (Yamato Rise) and three basins (Japan, Yamato and Tsushima Basins) around the Yamato Rise.At each station in the Basins (6 stations), we observed "the bottom layer," a layer of constant potential temperature (within ±0.0005°C) below 2,000–2,500 m …


Grazer Control Of The Fine-Scale Distribution Of Phytoplankton In Warm-Core Gulf Stream Rings, M. R. Roman, C. S. Yentsch, A. L. Gauzens, D. A. Phinney Jan 1986

Grazer Control Of The Fine-Scale Distribution Of Phytoplankton In Warm-Core Gulf Stream Rings, M. R. Roman, C. S. Yentsch, A. L. Gauzens, D. A. Phinney

Journal of Marine Research

We measured in situ rates of primary production, zooplankton grazing and the fine-scale distribution of zooplankton abundance, along with continuous observations of salinity, temperature and fluorescence in vertical profiles of two warm-core Gulf Stream rings and a station in the northern Sargasso Sea. A subsurface chlorophyll maximum was located within the pycnocline at all nineteen of the pump stations. In the majority of pump profiles, subsurface chlorophyll maxima coincided with maxima in particulate organic carbon and ATP. However, neither zooplankton biomass or numerical abundance were related to chlorophyll concentrations. Maxima in zooplankton biomass and grazing generally occurred at depths of …


The Effects Of The Filter-Feeding Clam Mercenaria Mercenaria On Carbon Cycling In Experimental Marine Mesocosms, Peter H. Doering, Candace A. Oviatt, John R. Kelly Jan 1986

The Effects Of The Filter-Feeding Clam Mercenaria Mercenaria On Carbon Cycling In Experimental Marine Mesocosms, Peter H. Doering, Candace A. Oviatt, John R. Kelly

Journal of Marine Research

The metabolism and the fate of 14C labelled carbon was examined in 4 outdoor mesocosm (13 m3) tanks containing both benthic and pelagic compartments. Mesocosms with (16/m2) and without the clam, Mercenaria mercenaria were compared. System production, net and gross sedimentation of particulate carbon and benthic remineralization of dissolved inorganic nitrogen were all greater in mesocosms with clams. A filtration rate model, dependent on clam size and temperature, explained between 74–114% of the increased gross sedimentation in clam tanks relative to controls.The higher production in the clam tanks was at least in part due to …

Thermohaline Forcing Of Eastern Boundary Currents: With Application To The Circulation Off The West Coast Of Australia, Julian P. Mccreary Jr., Satish R. Shetye, Pijush K. Kundu Jan 1986

Thermohaline Forcing Of Eastern Boundary Currents: With Application To The Circulation Off The West Coast Of Australia, Julian P. Mccreary Jr., Satish R. Shetye, Pijush K. Kundu

Journal of Marine Research

The linear, viscid, continuously stratified model of McCreary (1981) is extended to allow for thermohaline forcing by a specified, longitudinally independent, surface density field ρs. When the ocean is unbounded and ρs is steady, the density field is altered throughout the water column by vertical diffusion. If ρs increases poleward, the resulting pressure field slopes downward toward the pole in the upper water column, and there is an associated eastward geostrophic current. This interior current forces downwelling at an eastern ocean boundary, and generates a poleward surface coastal current and an equatorward undercurrent. For realistic choices …


Effects Of California El Niño 1982-1984 On The Northern Anchovy, Paul C. Fiedler, Richard D. Methot, Roger P. Hewitt Jan 1986

Effects Of California El Niño 1982-1984 On The Northern Anchovy, Paul C. Fiedler, Richard D. Methot, Roger P. Hewitt

Journal of Marine Research

El Niño caused physical and biological changes in the northern anchovy habitat off southern California. Anomalous sea surface temperatures, surface currents, mixed layer depths, and plankton biomass levels began to appear in late 1982 and persisted into 1984. Growth of juvenile and adult anchovy slowed during El Niño, probably due to reduced availability of zooplankton prey. A decrease in size-at-age in early 1983, with a recovery in late 1984, can be explained by movements of the stock and the latitudinal cline in size-at-age. Spawning range expanded in 1983 due to shifts in sea surface temperature boundaries. Early larval mortality was …


Predictions Of Sediment Trap Biases In Turbulent Flows: A Theoretical Analysis Based On Observations From The Literature, Cheryl Ann Butman, William D. Grant, Keith D. Stolzenbach Jan 1986

Predictions Of Sediment Trap Biases In Turbulent Flows: A Theoretical Analysis Based On Observations From The Literature, Cheryl Ann Butman, William D. Grant, Keith D. Stolzenbach

Journal of Marine Research

The physical variables affecting the trapping of particles in sediment collectors are grouped into a set of six dimensionless parameters, as a function of a dimensionless particle collection efficiency. Relevant laboratory calibration studies on sediment trap biases are evaluated to determine the quantitative dependence between collection efficiency and three of the parameters, trap Reynolds number, the ratio of flow speed to particle fall velocity and the ratio of trap height to mouth diameter, as well as trap geometry. We find that few of the parameters have been systematically tested in the laboratory and that trap Reynolds number-similarity for field conditions …


Seasonal Lags Between Organic Carbon Deposition And Mineralization In Marine Sediments, David T. Rudnick, Candace A. Oviatt Jan 1986

Seasonal Lags Between Organic Carbon Deposition And Mineralization In Marine Sediments, David T. Rudnick, Candace A. Oviatt

Journal of Marine Research

The fate of phytoplankton detritus in the muddy sediments of shallow marine ecosystems was studied by labelling the water column of a 13 m3 microcosm with radiocarbon bicarbonate from January to July. By the end of the study, more than 9% of the original inorganic label was found as organic carbon in the top 10 cm of sediment. The accumulation of labelled organic carbon in the sediment totalled 14.5 gC/m2. We estimate that this amount represented 15% of daytime net primary production and roughly half of the labelled organic carbon that was deposited on the sediment. The …


Anomalous Diurnal Tidal Currents On The Yermak Plateau, Kenneth Hunkins Jan 1986

Anomalous Diurnal Tidal Currents On The Yermak Plateau, Kenneth Hunkins

Journal of Marine Research

Recent observations made over the Yermak Plateau, a 100 × 200 km submarine feature northwest of Svalbard, show that ocean currents in that area are dominated by diurnal tidal currents although semidiurnal tidal displacements of the surface always exceed diurnal tidal displacements along the coast in the Arctic Ocean. Currents were recorded with meters suspended below two drifting ice stations, FRAM III in 1981 and FRAM IV in 1982, as they traveled over several weeks from a region of abyssal depths onto the western flank of the Yermak Plateau. Ice drift velocity was calculated from satellite positions and then vectorially …


A Model For The Vertical Flux Of Nitrogen In The Upper Ocean: Simulating The Alteration Of Isotopic Ratios, Mark A. Altabet, Allan R. Robinson, Leonard J. Walstad Jan 1986

A Model For The Vertical Flux Of Nitrogen In The Upper Ocean: Simulating The Alteration Of Isotopic Ratios, Mark A. Altabet, Allan R. Robinson, Leonard J. Walstad

Journal of Marine Research

An idealized, one-dimensional, constant diffusivity mathematical model for the study of the vertical flux of nitrogen in the upper-ocean is presented. We attempt to simulate observed patterns in vertical profiles for the natural abundance of 15N in particulate organic nitrogen (PON) and the concentrations of PON and NO3−. The concentration of phytoplankton nitrogen (II) increased as a result of either increasing the upward flux of NO3−(N) or by increasing the residence time of II. A minimum in the δ15N of phytoplankton nitrogen (δ2) appeared near a maximum in II …


Variability Of The Ocean Surface Color Field In Central California Near-Coastal Waters As Observed In A Seasonal Analysis Of Czcs Imagery, Vittorio Barale, Ruth Wittenberg Fay Jan 1986

Variability Of The Ocean Surface Color Field In Central California Near-Coastal Waters As Observed In A Seasonal Analysis Of Czcs Imagery, Vittorio Barale, Ruth Wittenberg Fay

Journal of Marine Research

A time series of Coastal Zone Color Scanner images has been analyzed, on a seasonal basis, to gain a perspective on the ocean surface color field heterogeneity in central California near-coastal waters. Seasonal composite maps of the diffuse attenuation coefficient at 490 nm were derived, in the form of arithmetic means and corresponding variances, for the years 1981, 1982 and 1983. By identifying "open ocean," "transition" and "coastal" water types in the mean images, and comparing values and areal extention of each class in different periods and years, a distinct seasonality of the spatial characteristics of ocean color emerged. Analogous …
