Temporal Changes in Some Fresh Water Temperature Structures
Temporal Changes Fresh Water Temperature Structures
2009/4/2
Microstructure is examined in 61 temperature-depth profiles which were obtained at one location in a fresh water lake. Over the 12 hr of observation, specific features of the microstructure are contin...
Verification of Numerical Models of Lake Ontario. II. Stratified Circulations and Temperature Changes
Verification of Numerical Models Lake Ontario Temperature Changes
2009/3/24
Data from the 1972 International Field Year on Lake Ontario are used to test the performance of three-dimensional hydrodynamic models of large lakes. This study is a sequel to a previous report concer...
Remote Sensing of Ocean Currents and Sea Surface Temperature Changes Derived from the Nimbus II Satellite
Sea Surface Temperature Ocean Currents Nimbus II Satellite
2009/3/9
Nimbus II High Resolution Infrared Radiometer (HRIR) data, sensitive in the 3.4–4.2 μ window, were analyzed over several oceanic regions. Current boundaries such as the north wall of the Gulf Stream h...
Predicting Changes in Tidal Regime：The Open Boundary Problem
Tidal Regime The Open Boundary Problem Predicting Changes
2009/3/7
Attempts to predict the impact on a tidal regime of large engineering structures are generally based on the use of a numerical model which is calibrated to reproduce the natural tidal regime and then ...
Topographically Induced Changes in the Structure of an Inertial Coastal Jet：Application to the Agulhas Current
Inertial Coastal Jet Agulhas Current
2009/2/13
Calculations are made of the changes in the structure of an inertial current which can be induced by slow changes in the topography of the continental shelf and slope along which it flows. The particu...
Changes in Thermal Structure of the Equatorial Pacific during the 1972 El Niño as Revealed by Bathythermograph Observations
Thermal Structure El Niñ o Equatorial Pacific Bathythermograph Observations
2009/2/8
Bathythermograph data from the equatorial Pacific are used to study changes in upper ocean thermal structure during the period 1971–73 using data averaged over 2- or 3-month segments. This gives reaso...
Scattering of Coastally Trapped Waves by Changes in Continental Shelf Width
Coastally Trapped Waves Continental Shelf Width
2009/1/7
The scattering of dispersive, barotropic, coastally-trapped waves by narrowing and widening shelves is investigated. The shelves considered maintain a shelf-similar exponential shape. For such shelves...
Acoustic Detection of Greenhouse-induced Climate Changes in the Presence of Slow Fluctuations of the Thermohaline Circulation
El Niñ o-Southern Oscillation Acoustic Detection Greenhouse-induced Climate Thermohaline Circulation
2008/12/18
Munk and Forbes have proposed to detect greenhouse gas-induced climate changes in the World Ocean with an array of long-range acoustic transmissions from Heard Island in the southern Indian Ocean. We ...
Response of Circulation and Heat Transport in the North Atlantic to Changes in Thermohaline Forcing in Northern Latitudes：A Model Study
Northern Latitudes Thermohaline Forcing Heat Transport
2008/12/17
To avoid an explicit simulation of the overflows across the Greenland-Scotland ridge, many models of the large-scale ocean circulation seek to include the net effect of the inflowing dense water masse...
Sensitivity of a World Ocean GCM to Changes in Subsurface Mixing Parameterization
World Ocean GCM subgrid-scale mixing Subsurface Mixing Parameterization
2008/12/16
The sensitivity of a coarse-resolution model of the World Ocean to parameterization of subgrid-scale mixing is examined. The model is based on the GFDL code. Results are presented from a series of mod...
Decadal Changes in the Mode Waters in the Midlatitude North Pacific
North Pacific subtropical mode water North Pacific central mode water
2008/11/18
Temporal changes in the properties of the North Pacific subtropical mode water (NPSTMW) and the North Pacific central mode water (NPCMW), which occurred around the mid-1970s, are investigated using te...
Deep and Bottom Waters in the Eastern Scotia Sea: Rapid Changes in Properties and Circulation
Bottom Waters Eastern Scotia Sea Properties Circulation
2008/8/12
Two meridional hydrographic transects (in 1995 and 1999) across the eastern Scotia Sea are used to investigate variability in the deep and bottom waters between the South Scotia Ridge and South Georgi...
Annual and Interannual Changes in the North Atlantic STMW Layer Properties
Annual and Interannual Changes North Atlantic STMW Layer Properties
2008/8/7
Subtropical mode waters (STWMs) are water masses formed in winter by convective mixing on the equatorward side of western boundary currents in the subtropical gyres. After the return of the seasonal s...
