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 …

Vertical Patterns In 15n Natural Abundance In Pon From The Surface Waters Of Warm-Core Rings, Mark A. Altabet, James J. Mccarthy Jan 1986

Vertical Patterns In 15n Natural Abundance In Pon From The Surface Waters Of Warm-Core Rings, Mark A. Altabet, James J. Mccarthy

Journal of Marine Research

The natural abundance of 15N in PON from the upper 200 m of 4 warm-core rings and the Sargasso Sea was measured. Minima in the δ15N of PON often occurred near the depth at which NO3− was first detectable. Frequently, maxima in PON concentration and minima in C/N ratio also co-occurred in this region. The average value for the δ15N of PON below the top of the nitracline was almost always greater than that above the top of the nitracline. The observed vertical pattern for the δ15N of PON is most …

The Effects Of Intra-Specific Density And Food Supply On Growth And Reproduction In An Infaunal Polychaete, Polydora Ligni Webster, Roman N. Zajac Jan 1986

The Effects Of Intra-Specific Density And Food Supply On Growth And Reproduction In An Infaunal Polychaete, Polydora Ligni Webster, Roman N. Zajac

Journal of Marine Research

In two laboratory experiments decreasing food supply and increasing intra-specific density generally had negative effects on growth and reproduction in the spionid polychaete Polydora ligni. These included longer maturation times at smaller worm size, longer times to deposition of the first brood of eggs and inter-brood period, and decreases in the number of gametogenic segments, egg capsules and fecundity. The number of eggs deposited per capsule was not affected by the treatments. Analysis of field data indicated a significant negative correlation between intra-specific density and fecundity, suggesting that the laboratory results reflect field conditions. Populations of opportunistic infauna, like Polydora …

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 Model Study Of The Seasonal Cycle Of The Arabian Sea Surface Temperature, Satish R. Shetye Jan 1986

A Model Study Of The Seasonal Cycle Of The Arabian Sea Surface Temperature, Satish R. Shetye

Journal of Marine Research

The Annual variation of the SST along a zonal strip from the coast of Somalia to the southwest coast of India was simulated using available data (monthly-mean heat and momentum fluxes across the air-sea interface, surface advective field, etc.) as input to a Kraus-Turner mixed-layer model. Three cases were examined. In the first, influence of surface fluxes alone was considered. The second included the effects of surface fluxes and vertical advection. Then, effect of horizontal advection was added.The model forced with the surface heat and momentum fluxes alone simulated reasonably well the SST variability throughout the year except during the …

Nekton Falls, Low-Intensity Disturbance And Community Structure Of Infaunal Benthos In The Deep Sea, Craig R. Smith Jan 1986

Nekton Falls, Low-Intensity Disturbance And Community Structure Of Infaunal Benthos In The Deep Sea, Craig R. Smith

Journal of Marine Research

A simulation of natural disturbance at the bathyal seafloor evoked rapid response from dominant infaunal species, for the first time providing experimental evidence that similar disturbances structure normal deep-sea communities. Parcels of dead fish (1–40 kg) were placed on the seafloor at a depth of 1310 m in the Santa Catalina Basin and monitored with Alvin and free-vehicle cameras for up to 8 wk. Dense aggregations of fish and ophiuroids were rapidly attracted to the baitfalls; in the process of consuming the bait, these megafaunal scavengers disrupted sediment surface structures and resuspended substantial amounts of sediment. The predominant macrofaunal effect …

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 …

Observations Of The Horizontal Separation Of The Salinity Core And The Current Core In The Atlantic Equatorial Undercurrent, Eberhard Fahrbach, Jens Meincke, Alexander Sy Jan 1986

Observations Of The Horizontal Separation Of The Salinity Core And The Current Core In The Atlantic Equatorial Undercurrent, Eberhard Fahrbach, Jens Meincke, Alexander Sy

Journal of Marine Research

From January to June 1979 the R. V. Meteor surveyed the central equatorial Atlantic on a line along 22W from 2S to 3N. By means of CTD and horizontal deflection measurements of a towed undulating instrument, the "Delphin," a time series of the horizontal location of the velocity core of the Equatorial Undercurrent and its related salinity maximum could be obtained. The time interval of observations between the 11 "Delphin" sections ranged from 5 to 30 days. In the mean the salinity maximum is located 30 km south of the velocity maximum. The separation distance depends on the meridional location …

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 …

Distribution Of Dissolved Co2 In The Red Sea And Correlations With Other Geochemical Tracers, A. Papaud, A. Poisson Jan 1986

Distribution Of Dissolved Co2 In The Red Sea And Correlations With Other Geochemical Tracers, A. Papaud, A. Poisson

Journal of Marine Research

The concentration of dissolved inorganic carbon in the Red Sea was studied using the following model:TCO2 = TCO2o + ΔTCO2bio + ΔTCO2ant. The conservative part TCO2o was correlated with the potential temperature T. The term ΔTCO2bio represents the exchanges with the marine biosphere and was expressed in the form aΔX + bΔY with X = O2, NO3, PO4 and Y = TA, Ca. The term ΔTCO2ant represents the excess of TCO2 due to the penetration of human …
