The thermocline is the relatively thin layer of water lying in between the warm epilimnion and cool hypolimnion, and in this region the water temperature drops rapidly with every foot of increasing depth. You may have actually seen the thermocline on your depthfinder, because the density change in the water here is strong enough to deflectFile Size: 15KB. Which is the definition of the thermocline? A. The thermocline is the boundary between colder ocean water near the surface and warmer ocean water at greater depth. B. The thermocline is the boundary between warmer ocean water near the equator and colder ocean water near the poles. C. The thermocline is where warm ocean currents sink to become.

Question: What is a thermocline? Water Temperature: There are a number of factors that affect the temperature of water. One is depth. Deeper water does not receive as much sunlight, and so it is. Thermocline definition, a layer of water in an ocean or certain lakes, where the temperature gradient is greater than that of the warmer layer above and the colder layer below. See more.

  The thermocline is a layer within a body of water where the temperature changes rapidly with depth. The word “thermocline” first appears in the limnology literature of the late nineteenth century (Pedlosky ) and is then more frequently referred as a discontinuity layer or transition layer (Sverdrup et al. ).It was very difficult to detect the deep ocean thermocline until the Cited by: In bass fishing, you need only concern your efforts from the thermocline upward. 99% of life will be above the bottom of the thermocline. In the summer, this is how I first approach my decision on what depth to fish. If I’m seeing the thermocline at 15 to 18 feet, I’m going to target structure especially during the mid-day at that depth.

5 TR PREDICTION OF THE THERMOCLINE DEPTH P. MAZEIKA Formulation Branch Oceanographic Prediction Division JUNE \J\s\ u Woods Hole Oco Institution U.S. NAVY HYDROGRAPHIC OFFICE WASHING D. Price $ ABSTRACT in order to derive a. A thermocline (also known as the thermal layer or the metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g.

water, as in an ocean or lake; or air, e.g. an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below.

In the ocean, the thermocline divides the upper mixed layer from the calm deep water below. Thermocline, oceanic water layer in which water temperature decreases rapidly with increasing depth. A widespread permanent thermocline exists beneath the relatively warm, well-mixed surface layer, from depths of about m ( feet) to about 1, m (3, feet), in which interval temperatures.

Top of Thermocline Depth (TTD) The Top of Thermocline Depth (TTD) is defined as the depth above which the temperature is superior than the surface temperature (at 10m depth) minus °C (cf.,).

The surface layer of the ocean above the TTD is warm relative to the deeper ocean and the TTD may also be called the surface Warm Layer Depth (WLD). The thermocline is a layer of water towards the bottom that has no oxygen or very little oxygen. Fish can venture below the thermocline to feed but they can’t stay there for extended periods of time.

Thermocline plays a sigificant role in how you approach fishing for catfish in the summer. Not only where you fish but the techniques you use as. The red line in this illustration shows a typical seawater temperature profile. In the thermocline, temperature decreases rapidly from the mixed upper layer of the ocean (called the epipelagic zone) to much colder deep water in the thermocline (mesopelagic zone).

Below 3, feet to a depth of ab feet, water temperature remains depths be feet, the. The relationship between thermocline depth and SST anomalies in the eastern equatorial Pacific: Seasonality and Decadal Variations Jieshun Zhu1,2, Arun Kumar1 and Bohua Huang3,4 1.

Motivations 3. Seasonality of ZSST relationship 2. Data Fig. 1 Lead-lag File Size: KB. A thermocline is an underwater layer where the temperature decreases rapidly as you go deeper.

Colder water is dense so it sinks to the lake bottom while warmer water is lighter and floats above. Thermocline depths tend to be consistent for the same calendar month year. Fishing the thermocline is important. I'm going over what the thermocline looks like and how to fish it. If you have any qestions let me know.

Category People & Blogs. In extra-tropical regions a permanent (or main) thermocline is found between m and m. However the thermocline depth varies seasonally, especially in the mid-latitude regions where a secondary and much shallower thermocline (above 50m) occurs in summer.

Read the depth on the calibrated side of the bathythermograph at the top of the water column and read the temperature off the temperature plate. Invert the instrument and press the valve to release the water. Shake until all water is out before using it again. Finding the Thermocline. Continue taking readings at successively lower depths until.

thermocline A thermocline (sometimes metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below.

Note that the grid cell positions along the Z axis determines the possible values of thermocline depth. Your thermocline will be somewhat blocky unless you apply some X and Y smoothing.

the depth of thermocline at or near the time of maximum heat content. 0 E and are surface and bottom temperatures at this time (Japanese temperatures are from Yoshimura, /).

g' is the reduced gravity (defined in the text). Some lakes won't have a thermocline. The level of thermocline usually follows clarity.

The clearer the water, the deeper the thermocline. On dingier lakes, it may be only six or eight feet. In clearer ones it may be as deep as 30 feet. The way I find the "cline" is to turn on Author: Randy Womack.

The thermocline is important when trying to locate fish because it is the depth that is most comfortable for the fish.

The thermocline is the comfort zone for the fish because it contains the coolest water that has abundant oxygen and prey. The light penetration at the thermocline level is also improved. North Atlantic Deep Water flows southerward below the thermocline of the subtropical gyre.: In the open ocean, many sinking cells are lost to the deep, but refuge populations can persist near the thermocline.: If a zone undergoes dramatic changes in temperature with depth, it contains a thermocline.: The tropical thermocline is typically deeper than the thermocline at higher latitudes.

Thermocline definition is - the region in a thermally stratified body of water which separates warmer surface water from cold deep water and in which temperature decreases rapidly with depth.

The line separating the two is the thermocline. During summertime, anglers can identify the depth of the thermocline on electronics and eliminate all deeper water.

Turn your unit’s sensitivity to a high setting and you should see a horizontal line on the screen (the thermocline). The depth of the thermocline varies lake-to-lake. It may be as. A thermocline is usually defined as a significant temp change in a relatively small depth change.

As a scuba diver I have seen a surface temp of 70 with a gradual decrease to 65 degrees at feet, then a rapid drop of 10 to 12 degrees in the next 2 or 3 feet. The book that comes with this unit clearly shows how you can set-up and "see" a thermocline.

However, regardless with how I change settings, I've never "seen" a thermocline on this unit. I think I agree with what has been previously said, in that .
