Monitoring The Upper Southeastern Atlantic Transports Using Altimeter Data, Silvia L. Garzoli, Gustavo J. Goñi, Arthur J. Mariano, Donald B. Olson Jan 1997

Monitoring The Upper Southeastern Atlantic Transports Using Altimeter Data, Silvia L. Garzoli, Gustavo J. Goñi, Arthur J. Mariano, Donald B. Olson

Journal of Marine Research

A large in-situ data set, collected in the southeastern Atlantic Ocean, is merged with the TOPEX/POSEIDON altimeter observations in order to verify the use of altimeter data in monitoring the transports of the Agulhas/Benguela system. Comparisons between altimeter observations and either moored current meters or inverted echo sounder measurements shows that the sea-surface elevation anomaly is significantly correlated with the thermocline depth and the surface dynamic height, respectively. Knowing the least-squares regression parameters, it is possible to calculate the transports by using geostrophy and either a two-layer or a continuously-stratified model. The transports obtained from fits of dynamic height to …


Barotropic, Wind-Driven Circulation In A Small Basin, S. P. Meacham, P. S. Berloff Jan 1997

Barotropic, Wind-Driven Circulation In A Small Basin, S. P. Meacham, P. S. Berloff

Journal of Marine Research

We study the asymptotic behavior (large time) of a simple, wind-driven, barotropic ocean model, described by a nonlinear partial differential equation with two spatial dimensions. Considered as a dynamical system, this model has an infinite-dimensional phase space. After discretization, the equivalent numerical model has a phase space of finite but large dimension. We find that for a considerable range of friction, the asymptotic states are low-dimensional attractors. We describe the changes in the structure of these asymptotic attractors as a function of the eddy viscosity of the model. A variety of different types of attractor are seen, with chaotic attractors …


The Hydrography And Circulation Of The Upper 1200 Meters In The Tropical North Atlantic During 1982-91, Gennady Chepurin, James A. Carton Jan 1997

The Hydrography And Circulation Of The Upper 1200 Meters In The Tropical North Atlantic During 1982-91, Gennady Chepurin, James A. Carton

Journal of Marine Research

We assemble a collection of 7591 conductivity-temperature-depth stations in the tropical Atlantic between 5S and 20N for the period 1982–1991 using data from the Soviet SECTIONS program enhanced by contributions primarily from the WESTRAX and FOCAL/SEQUAL programs. Most of the stations are west of 30W, forming a series of 21 surveys. In addition there were five multi-ship basinwide surveys, each taking 1.5–3 months to complete. The quality of the SECTIONS data is discussed and comparisons between the data sets are shown. Within the pycnocline, southern water is distinguished by salinity that is 0.3 psu lower than its northern counterpart at …


Updated Bathymetry Of The Anegada-Jungfern Passage Complex And Implications For Atlantic Inflow To The Abyssal Caribbean Sea, David M. Fratantoni, Rainer J. Zantopp, William E. Johns, Jerry L. Miller Jan 1997

Updated Bathymetry Of The Anegada-Jungfern Passage Complex And Implications For Atlantic Inflow To The Abyssal Caribbean Sea, David M. Fratantoni, Rainer J. Zantopp, William E. Johns, Jerry L. Miller

Journal of Marine Research

Recent bathymetric, hydrographic and direct velocity measurements indicate that a previously unexplored deep passage in the northeastern Caribbean Sea may play a significant role in the abyssal ventilation of this basin. The Anegada-Jungfern Passage complex has long been recognized as the sole pathway for deep Atlantic inflow to the eastern Caribbean. The Anegada Passage (sill depth 1915 m) connects the Atlantic Ocean with the small Virgin Islands Basin, while Jungfern Passage (sill depth 1815 m) connects the latter with the large and deep Venezuela Basin comprising the eastern third of the Caribbean Sea. In the region of Jungfern Passage recent …


Implications Of The Salt And Heat Budgets Of The Gulf Of Thailand, Kate Stansfield, Chris Garrett Jan 1997

Implications Of The Salt And Heat Budgets Of The Gulf Of Thailand, Kate Stansfield, Chris Garrett

Journal of Marine Research

Hydrographic data collected during 1959 and 1960 in the Gulf of Thailand, combined with supporting climatological data, have been used to investigate the salt and heat budgets of the Gulf. A simple model including mixing, net precipitation, local river run-off and Ekman flux predicts the flushing time of the Gulf, associated with processes other than the Ekman flux, to be 12.0 months, but predicts too small a magnitude and the wrong phase for the observed seasonal salinity cycle. Adding the discharge from the Mekong River reduces the flushing time to 5.4 months and improves the fit to the magnitude of …

Morphological And Compositional Evidence For Biotic Precipitation Of Marine Barite, Miriam A. Bertram, James P. Cowen Jan 1997

Morphological And Compositional Evidence For Biotic Precipitation Of Marine Barite, Miriam A. Bertram, James P. Cowen

Journal of Marine Research

Barite formation in the surface oceans is generally assumed to be dominated by abiotic precipitation. Acceptance of this pathway is largely the result of the absence of a pelagic marine organism known to precipitate the ovoid to rounded-rectangular barite crystals typically observed in marine waters and sediments. Barite crystals observed in net-tow particles and on substrates retrieved from the seafloor (both in the central North Pacific) were examined by scanning electron microscopy and energy dispersive X-ray spectrometry. Three distinct crystalline forms of barite were observed: ovoid and hexagonal crystals several microns in diameter, and aggregates of submicron-sized crystals. Ovoid and …


Sediment Resuspension Rates, Organic Matter Quality And Food Utilization By Sea Scallops (Placopecten Magellanicus) On Georges Bank, Jonathan Grant, Peter Cranford, Craig Emerson Jan 1997

Sediment Resuspension Rates, Organic Matter Quality And Food Utilization By Sea Scallops (Placopecten Magellanicus) On Georges Bank, Jonathan Grant, Peter Cranford, Craig Emerson

Journal of Marine Research

Benthic detritus, bacteria, and settled phytoplankton are transported into the water column by resuspension, potentially providing a high quality food source to suspension feeders. Two aspects of resuspension must be considered in relation to food supplies for suspension feeders: the flux of particles from the sediments to the water column and its food value. Sediment resuspension rates on Georges Bank and the role of resuspended sediment in the diet of sea scallops (Placopecten magellanicus) were determined in laboratory flume experiments and shipboard feeding experiments, respectively. Resuspended carbon flux was estimated from flume bedload transport rates and the mass …

The Cloning And Characterization Of Toad-64: A Gene Expressed Transiently During Neuronal Differentiation In The Mammalian Nervous System, Jane Elizabeth Minturn May 1996

The Cloning And Characterization Of Toad-64: A Gene Expressed Transiently During Neuronal Differentiation In The Mammalian Nervous System, Jane Elizabeth Minturn

Yale Medicine Thesis Digital Library

During the development of the mammalian central nervous system, a pool of morphologically homogeneous, mitotically active progenitor cells in the neural tube gives rise to the enormously diverse population of postmitotic cells that assume the properties of neurons or glia. Postmitotic neurons elaborate processes that are involved in the migration of neurons to their adult positions as well as the elaboration of axonal and dendritic arbors that will ultimately form specific synaptic contacts. The generation of postmitotic neurons from precursor cells is a central differentiative event in development, but molecular markers of this event are few.Using 2D gel electrophoresis, proteins …

Distinct Year-To-Year Particle Flux Variations Off Cape Blanc During 1988-1991: Relation To Δ 18o-Deduced Sea-Surface Temperatures And Trade Winds, G. Fischer, B. Donner, V. Ratmeyer, R. Davenport, G. Wefer Jan 1996

Distinct Year-To-Year Particle Flux Variations Off Cape Blanc During 1988-1991: Relation To Δ 18o-Deduced Sea-Surface Temperatures And Trade Winds, G. Fischer, B. Donner, V. Ratmeyer, R. Davenport, G. Wefer

Journal of Marine Research

Particle fluxes measured from 1988 to 1991 adjacent to a coastal upwelling site off Cape Blanc showed significant interannual variability of fluxes and sea-surface temperatures (SST) deduced from stable oxygen isotope analysis of the planktonic foraminifera Globigerinoides ruber and, partly, of the pteropod Limacina inflata. For the duration of the study period, a decrease in the seasonality of SST's was observed, as well as a significant decrease in the average annual SST from 24.4° to 20.8°C. This cooling trend was mainly the effect of a drastic decrease in the summer to fall SST (from 27.2° to 21.8°C). In comparison, …


The Role Of Mesoscale Hydrography On Microbial Dynamics In The Northeast Atlantic: Results Of A Spring Bloom Experiment, B. Karrasch, H. G. Hoppe, S. Ullrich, S. Podewski Jan 1996

The Role Of Mesoscale Hydrography On Microbial Dynamics In The Northeast Atlantic: Results Of A Spring Bloom Experiment, B. Karrasch, H. G. Hoppe, S. Ullrich, S. Podewski

Journal of Marine Research

During RV Meteor cruise No. 10 from May to June 1989 (JGOFS pilot study) bacterial and picocyanobacterial abundance, biomass, and bacterial production were estimated at two drift stations close to 47N, 20W and 58N, 20W in the northeast Atlantic. At 47N two different mesoscale hydrographic structures were sampled which divided the drift experiment into a cyclonic and an anticyclonic circulation phase. Transition from one phase to the next was clearly reflected by changes of the biological structure in the upper water column. Phytoplankton stocks maintained during the cyclonic phase were about 1.8 times higher than those of the anticyclonic phase …


Biological Removal Of Fine-Grained Lithogenic Particles From A Large River Plume, M. J. Dagg, E. P. Green, B. A. Mckee, P. B. Ortner Jan 1996

Biological Removal Of Fine-Grained Lithogenic Particles From A Large River Plume, M. J. Dagg, E. P. Green, B. A. Mckee, P. B. Ortner

Journal of Marine Research

The pelagic tunicate, Oikopleura dioica, feeds by non-selectively filtering particles in the size range of 0.2–20 μm. In the northern Gulf of Mexico, particulate matter in this size range contains large amounts of fine-grained lithogenic material because of the influence of the Mississippi River. During May 1992, O. dioica populations filtered between 2 and 44% (mean = 20%) of the upper 5 m each day. The filtered lithogenic particles either remain in the oikopleurid house or are defecated in fecal pellets which have high sinking velocities. Either way, the larvacean populations significantly alter the fates of fine-grained lithogenic particles …


Molecular Diversity Of The Copepod, Nannocalunus Minor: Genetic Evidence Of Species And Population Structure In The North Atlantic Ocean, Anna Bucklin, Todd C. Lajeunesse, Eva Curry, John Wallinga, Karen Garrison Jan 1996

Molecular Diversity Of The Copepod, Nannocalunus Minor: Genetic Evidence Of Species And Population Structure In The North Atlantic Ocean, Anna Bucklin, Todd C. Lajeunesse, Eva Curry, John Wallinga, Karen Garrison

Journal of Marine Research

The abundant calanoid copepod, Nannocalanus minor, is widespread from the Florida Straits (FS), throughout the Gulf Stream and the Sargasso Sea, to the eastern North Atlantic Ocean. Does the species represent a single, randomly-mating population across this extensive region, or does it comprise a number of genetically distinct populations or taxonomically distinct forms? What are patterns and pathways of dispersal of the copepod across the North Atlantic? These questions were addressed using population genetic analysis of DNA sequence variation of a 440 base-pair region of the mitochondrial 16S rRNA gene. This analysis separated N. minor into two genetically distinct …


A High Resolution Camera System (Parca) For Imaging Particles In The Ocean: System Design And Results From Profiles And A Three-Month Deployment, Volker Ratmeyer, Gerold Wefer Jan 1996

A High Resolution Camera System (Parca) For Imaging Particles In The Ocean: System Design And Results From Profiles And A Three-Month Deployment, Volker Ratmeyer, Gerold Wefer

Journal of Marine Research

For direct optical measurement of abundance, concentration and size distribution of marine particles, a high-resolution camera system (ParCa) was designed to improve on similar systems used by Honjo et al. (1984), Asper (1987) and others. Imaging a probe volume of up to 37 1, smallest particles with diameters of 50 μm can be counted. The images provide information on particle size, shape and abundance either during profiling through the water column or while moored in a certain depth over time. Depth profiles were acquired between fall 1992 and late spring 1993 on R. V. Meteor cruises M22-1 and M23-3 …


Seasonal Transport Variations Of The Wind-Driven Ocean Circulation In A Two-Layer Planetary Geostrophic Model With A Continental Slope, Toshihiro Sakamoto, Toshio Yamagata Jan 1996

Seasonal Transport Variations Of The Wind-Driven Ocean Circulation In A Two-Layer Planetary Geostrophic Model With A Continental Slope, Toshihiro Sakamoto, Toshio Yamagata

Journal of Marine Research

Using a simple two-layer planetary geostrophic model with a continental slope, the observed seasonal variation of the total transport of the Kuroshio is explained qualitatively for the first time in a quite concise way. During the period of weak winds in summer, the total transport is much larger than the nontopographic Sverdrup transport. This is because the joint effect of baroclinicity and bottom relief (so-called JEBAR) drives the barotropic flow with releasing the available potential energy accumulated in winter. In winter, on the other hand, the transport is much smaller than the nontopographic Sverdrup transport. This is mainly due to …


Carbon Cycling In Mesohaline Chesapeake Bay Sediments 2: Kinetics Of Particulate And Dissolved Organic Carbon Turnover, Eric E. Roden, Jon H. Tuttle Jan 1996

Carbon Cycling In Mesohaline Chesapeake Bay Sediments 2: Kinetics Of Particulate And Dissolved Organic Carbon Turnover, Eric E. Roden, Jon H. Tuttle

Journal of Marine Research

Temporal and depth variations in benthic carbon metabolism rates were examined in relation to particulate organic carbon (POC) deposition rates and particulate and dissolved organic carbon degradation kinetics in two sediments from the mesohaline region of Chesapeake Bay. The depth distribution of a single pool of metabolizable POC (MPOC) in mid-Bay sediments was estimated by curve-fitting of dry weight POC profiles (“1-G” approach). Estimated MPOC pools accounted for 3–4% of total POC content in the upper 10 cm of sediment. First-order MPOC decay constants of ≈10 yr−1 during the warm season were estimated from the ratio of …
