High-resolution thermistor chain data collected between 5 and 20 m in a large stratified freshwater lake
(Lake Constance) at a water depth of 60 m reveal the frequent occurrence of large-amplitude ($...
Development of internal solitary waves in various thermocline regimes-a multi-modal approach
internal solitary waves various thermocline regimes multi-modal approach
<
2009/11/12
A numerical analysis is made on the appearance of oceanic internal solitary waves in a multi-modal setting. This is done for observed profiles of stratification from the Sulu Sea and the Bay of Biscay...
Profile of an Isopycnal Surface in the Main Thermocline of the Sargasso Sea
Isopycnal Surface Main Thermocline Sargasso Sea
<
2009/4/2
The vertical displacement and slope of an isopycnal surface (by which is meant a density surface of constant σt) are described spatially. The data were acquired by towing pressure, temperature and con...
Spring Thermocline Behavior in Lake Ontario During IFYGL
Spring Thermocline Behavior Lake Ontario During IFYGL
<
2009/3/26
A dynamical analysis is presented of some observations made during the International Field Year on the Great Lakes (IFYGL) on the north shore of Lake Ontario at Oshawa. The data analyzed relate to wat...
Nearshore Lake Currents Measured During Upwelling and Downwelling of the Thermocline in Lake Ontario
Nearshore Lake Currents Thermocline Lake Ontario
<
2009/3/24
The upwelling-downwelling cycles observed along the north shore of Lake Ontario have periods of about 12 to 16 days in length. Currents associated with the downwelling cycle are typically stronger. Th...
On the Equilibrium Shape of the Thermocline in a Shore Zone
Equilibrium Shape Thermocline Shore Zone
<
2009/3/9
The typical spring thermal regime of Lake Ontario shows a thermocline surface of either a “wedge” or of a “lens” shape persisting in the shore zone for a considerable period. The summer regime is char...
A linear model of the thermocline is examined for an ocean bounded by both eastern and western coasts. The analysis is carried out on a β-plane for an ocean in which diffusion of heat but not of momen...
A Study of Velocity Profiles Through the Main Thermocline
Velocity Profiles Main Thermocline
<
2009/3/7
A time series of velocity profiles derived from three methods are used to describe the variations of current in time and in the vertical. Absolute velocity profiles were Obtained by acoustically track...
