Ninety percent of predatory fish gone from Caribbean coral reefs due to overfishing
Ninety percent predatory fish gone Caribbean coral overfishing
2017/3/14
Researchers at the University of North Carolina at Chapel Hill have found that up to 90 percent of predatory fish are gone from Caribbean coral reefs, straining the ocean ecosystem and coastal economy...
A Time-Series View of Changing Ocean Chemistry Due to Ocean Uptake of Anthropogenic CO2 and Ocean Acidification
Time-Series View Changing Ocean Chemistry Due Ocean Uptake Anthropogenic CO2 Ocean Acidification
2015/7/17
Sustained observations provide critically needed data and understanding not only about ocean warming and water cycle reorganization (e.g., salinity changes), ocean eutrophication, and ocean deoxygenat...
Madagascar's unique animal diversity due to immigration across oceans
animal diversity oceans
2014/7/17
A study by University of Queensland and international researchers has found that most of Madagascar’s unique present-day fauna may originally have arrived across long distances by air or sea.
Residual circulation due to internal waves shoaling on a slope
Residual circulation internal waves shoaling a slope
2014/4/17
We describe the residual circulation induced in a two-layer system when internal waves, with a wave length equal to or longer than the slope length, propagate over a sloping bottom and either reflect ...
Particle dispersal due to interplay of motions in the surface layer of a small reservoir
surface layer reservoir Particle dispersal
2014/4/16
Horizontal dispersion mechanisms must be well defined in order to determine the origin and fate of
heterogeneous distributions of biogeochemical material. Here data from an intensive field campaign i...
A mathematical barotropic model based upon the conservation of absolute vorticity is used to determine the effect of the spherical shape of the rotating earth [approximated by the beta (β) effect] on ...
The Seasonal Upwelling in the Gulf of Guinea Due to Remote Forcing
Seasonal Upwelling Remote Forcing Gulf of Guinea
2009/2/23
A linear model on an equatorial β plane is integrated over a 120-day period in a basin that approximates the tropical Atlantic Ocean. An increase in the westward wind stress of 0.025 N m−2 in th...
The Nature of the Poleward Heat Flux Due to Low-Frequency Current Fluctuations in Drake Passage
Poleward Heat Flux Drake Passage Low-Frequency Current Fluctuations
2009/2/16
Values of poleward heat flux due to low-frequency current fluctuations in Drake Passage are presented for 19 long-term current meter records obtained during 1975, 1976 and 1977. Most of the measuremen...
The Dynamics of Oceanic Fronts. Part II：Shelf Water Structure Due to Freshwater Discharge
Shelf Water Structure Freshwater Discharge Oceanic Fronts
2009/2/10
In Part I of this series, a framework was introduced for the study of oceanic frontal dynamics. The dynamics was studied by posing an initial value problem, starting with a near-surface discharge of b...
On the Parameterization of Diapycnal Fluxes due to Double-Diffusive Intrusions
Diapycnal Fluxes Double-Diffusive Intrusions
2009/2/8
An attempt is made to Parameterized the large-Scale average diapycnal (cross-isopycnal) mixing that presumably occurs in the thermohaline fronts that develop when large-scale epipycnal (along-isopycna...
A solution for a concentrated line front translating at speed U is given. It is shown that the frequency is near-inertial if Uc1, where c1 is the long internal wave speed of the first baroclinic mode....
Variation of Bulk-Derived Surface Flux, Stability, and Roughness Results Due to the Use of Different Transfer Coefficient Schemes
Bulk-Derived Surface Flux Transfer Coefficient Schemes
2009/1/15
Ten published bulk transfer coefficient schemes are used with more than 2600 sets of shipboard observations made in the North Atlantic at Ocean Station C over a one-year period. Using the same input d...
Topographic Drag Due to Barotropic Flow over the Continental Shelf and Slope
Topographic Drag Continental Shelf Barotropic Flow
2009/1/13
A barotropic model is formulated to investigate the topographic drag due to steady barotropic alongshore flow over the continental shelf and slope. The topography is extensive, irregular and of small ...
Steady Coastal Circulation Due to Oceanic Alongshore Pressure Gradients
Coastal Circulation Pressure Gradients
2009/1/7
A depth-averaged barotropic model is used to investigate the steady response of the coastal ocean to alongshore pressure gradients imposed by the deep ocean. Solution indicate that the dimensionless c...
Large-Scale, Low-Frequency Response on the Continental Shelf Due to Localized Atmospheric Forcing Systems
Large-Scale Continental Shelf Low-Frequency Response Localized Atmospheric Forcing Systems
2009/1/6
The first-order wave equation model of Gill and Schumann, which describes the flow induced on the continental shelf by the longshore wind stress, evaluated at the coast, is extended in three ways. Fir...
