C. mid-ocean ridges. SURVEY . Worms, mussels, and crabs are the common marine inhabitants of the hadopelagic region. D. continental rocks Weegy: Terrigenous sediment consists primarily of mineral grains eroded from continental rocks. A thermocline is a layer of water more often found in a large body of water where the temperature gradient is greater than that of the warmer layer above and the colder layer below. What is the best description of thermoclines based on latitude?a. W Which type of sea water has the greatest density? 272 pp. Addressing strong ocean currents and large waves adds engineering and construction expense. The density of seawater is controlled by temperature and salinity. 13. It is semi-permanent in the tropics, variable in temperate regions (often deepest during the summer), and shallow to nonexistent in the polar regions, where the water column is cold from the surface to the bottom. [40] The study passed sponge rubber balls through the system. OTEC plants could be perceived as either a threat or potential partner to fisheries or to seabed mining operations controlled by the International Seabed Authority. a) Polar . r The condensate is then compressed to the highest pressure in the cycle, requiring condensate pump work, WC. U.S. Patent No. In the ocean, the thermocline may be thought of as an invisible . We have also tested the new software at 38 knots tracking in 40 meters of water, using the B265 Transducer. For upwelling the cold sea water, a stationary hydraulically driven propeller (50 m diameter) is located on the deep sea floor at 500 to 1000 m depth with a flexible draft tube extending up to the sea surface. A shelf-mounted plant could be towed to the site and affixed to the sea bottom. Dennis A. Hansell, in Biogeochemistry of Marine Dissolved Organic Matter, 2002 1. OTEC can operate with a very high capacity factor and so can operate in base load mode. Gradients above this limit must be actively forced as, for example, in surface thermoclines below the wind mixed layer. n Thermoclines in oceans are best developed at A. lower longitudes. thermocline oceanic water layer in which water temperature decreases rapidly with increasing depth. To operate, the cold seawater must be brought to the surface. [36][failed verification], An ocean thermal energy conversion power plant built by Makai Ocean Engineering went operational in Hawaii in August 2015 . The average temperature is approximately 3.5 C. Which regions seawater is most likely to have the highest concentration of dissolved salts? [64] A plant of that size would power several thousand homes. Among ocean energy sources, OTEC is one of the continuously available renewable energy resources that could contribute to base-load power supply. Share sensitive information only on official, secure websites. T The expanding vapor turns the turbo-generator. C. lower latitudes. This vapor drives the turbine and the 2-phase mixture enters the condenser. Ocean Energy Council: How does OTEC work? Thermoclines in the ocean are best developed at ________. For these reasons, shelf-mounted plants are less attractive. This region is often below freezing point temperatures (< 0C). Heart rate $\quad 88$ beats $/ \mathrm{min}$ The steam vaporizes the ammonia working fluid of a closed-cycle loop on the other side of an ammonia vaporizer. A)lower latitudes B)higher latitudes C)both high and low latitudes D)regions close to continents Also a shore based open cycle plant was investigated. [57] In mid-2015, the 95%-complete project was temporarily put on hold while the resort resolved financial and ownership issues. That water is now discharged back to the ocean. One disadvantage of land-based facilities arises from the turbulent wave action in the surf zone. [46], A hybrid cycle combines the features of the closed- and open-cycle systems. [34] Currently, this is one of only two fully operational OTEC plants in the world. During this transition, a thermal bar may develop. [citation needed] Reducing costs remains an unsolved challenge, however. Temperature generally decreases with altitude, But the heat from the days exposure to sun is released at night, which can create a warm region at ground with colder air abve. x5,s is the mass fraction of vapor at state 5. - 4241964 A typical thermocline (well, maybe not . Thus, the parasitic condensate pump work, WC, computed here will be lower than if the heat exchanger pressure drop was included. On March 5, 2014, Ocean Thermal Energy Corporation (OTEC)[70] and the 30th Legislature of the United States Virgin Islands (USVI) signed a Memorandum of Understanding to move forward with a study to evaluate the feasibility and potential benefits to the USVI of installing on-shore Ocean Thermal Energy Conversion (OTEC) renewable energy power plants and Seawater Air Conditioning (SWAC) facilities. The vapor, which has left its salt and other contaminants in the low-pressure container, is pure fresh water. Atlantic cooling associated with NADW formation (0.3 PW north of 32S; 1 PW = 1015 W) and Southern Ocean cooling associated with AABW formation (0.4 PW south of 32S) are balanced mostly by 0.6 . w This phenomenon is commonly visible at those depths where the gradient is severe. nekton Most marine animals live near the surface of the ocean because of _____, which supports . H6=Hf, at T5. Direct-Contact Condensers for Open-Cycle OTEC Applications: Model Validation with Fresh Water Experiments for Structured Packings. [60], Lockheed Martin's Alternative Energy Development team has partnered with Makai Ocean Engineering[61] [93] It would also lead to enhanced carbon sequestration by the oceans from improved algae growth and mass gain by glaciers from the extra snow fall mitigating sea level rise or global warming process. What is the thermocline and where is it located quizlet? thermocline oceanic water layer in which water temperature decreases rapidly with increasing depth. The lower sea water surface temperature would enhance the local ambient pressure so that atmospheric landward winds are created. When these plumes are mixed, they are slightly denser than the ambient seawater. Submarines use the thermocline constantly to avoid detection. Is Virat Kohli joins Avas Living as new brand ambassador? Small bodies of water have regular over-turning of water between these 2 regions, which sustains organisms at the bottom with periodic replenishment of oxygen. What Role Applications Like ScreenRec can Play in Managing Remote Teams? It is important to know about layering because it affects ocean currents. ; 3 What causes thermocline in ocean? Such areas as the Weddell Sea in Antarctica produce the densest water of the oceans. In some schemes, the expanding vapor drives a low-pressure turbine attached to an electrical generator. After most of the steam has been condensed by spout condensers, the non-condensible gas steam mixture is passed through a counter current region which increases the gas-steam reaction by a factor of five. The primary approaches are active pumping and desalination. The temperature of the deep ocean drops gradually with depth. What is the best description of thermoclines based on latitude? Thermoclines in the ocean are best developed at lower. Suppose that the pressure inside the evaporator is maintained at the saturation pressure, T2. Their systems are tuned to surviving alone, navigating by using sounds and vibrations and using phytoplankton and zooplankton for sustenance. Since the thermocline has a sharp temperature gradient, it also has variable density along with its thickness. This problem has been solved! The governor of Hawaii, David Ige, "flipped the switch" to activate the plant. Thermoclines also play a role in meteorological forecasting. Hence the tropics are generally the best OTEC locations. Cline oscillation is a phenomenon where waves are created on the thermocline due to the density gradient. Thermoclines in the ocean are best developed at lower latitudes. Cables at depths greater than 1000 meters are difficult to maintain and repair. This extends the variety of fresh seafood products available for nearby markets. One main impact of thermoclines is that due to the lack of inter-region mixing, oxygen content in the hypolimnion rapidly depletes (since organisms utilize it, and there is no source below the cline). It is relatively easy to tell when you have reached the thermocline in a body of water because there is a sudden change in temperature. The opening of the research and development 100-kilowatt facility marked the first time a closed-cycle OTEC plant was connected to the U.S. Too much carbon dioxide in the air is a problem, as it causes the Earth to trap more heat. 21. System analysis indicates that a 2-megawatt plant could produce about 4,300 cubic metres (150,000cuft) of desalinated water each day. As the temperature continues to drop, the water on the surface may get cold enough to freeze and the lake/ocean begins to ice over. Conceptual Design of an Open-Cycle Ocean Thermal Energy Conversion Net Power-Producing Experiment (OC-OTEC NPPE). The absorption coefficient may range from 0.05 m1 for very clear fresh water to 0.5 m1 for very salty water. In this article, we will look at thermoclines, the role they play in the marine ecosystem, the various ocean layers, the impact on marine life, and a unique aspect of thermocline impact on the field of naval design and engineering. Pages 10 Ratings 100% (1) 1 out of 1 people found this document helpful; In a hybrid, warm seawater enters a vacuum chamber and is flash-evaporated, similar to the open-cycle evaporation process. Blood pressure $\quad 147 / 68 \mathrm{~mm} \mathrm{Hg}$ Aquaculture is the best-known byproduct, because it reduces the financial and energy costs of pumping large volumes of water from the deep ocean. With OTEC plants supplying water, the only cost is for extraction. The water can be used in chilled-water coils to provide air conditioning for buildings. This is known as an inversion ( a further example of a thermocline). New York: Oxford University Press. Forbes. Microalgae such as Spirulina, a health food supplement, also can be cultivated. The main aim is to prove the validity of computer models and demonstrate OTEC to the public. One of the most important impacts of the density gradient is the negative sound speed gradient across the thermocline. As temperature increases, the medium becomes rarer (with increased spaces between molecules), which decreases the density. The primary area of concern for thermoclines is the effects of these zones in the ocean. waiting for changes in US military contract policies. Avery, William H. and Chih Wu. [48], To avoid the turbulent surf zone as well as to move closer to the cold-water resource, OTEC plants can be mounted to the continental shelf at depths up to 100 meters (330ft). It is a demo plant capable of generating 105 kilowatts, enough to power about 120 homes. metal sulfides evaporites calcareous ooze manganese nodules 26. Thermoclines in the ocean are best developed at _____. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. Platforms require extensive pilings to maintain a stable base. Course Hero is not sponsored or endorsed by any college or university. Evaluate the status of F.N. The weather station Myggbuka at Greenlands east coast for example, which is only 2,100km away from Glasgow, detects monthly mean temperatures below 15C (5F) during 6 winter months in the year. Those familiar with oceanography will know that the term "cline" is often used to refer to layers . Another interesting feature of these oceans is the pelagic zones. Phones. However, as depth increases, the thermocline width increases and the gradient becomes harsher. Chapter 14. A popular choice of working fluid is ammonia, which has superior transport properties, easy availability, and low cost. A new thermocline develops where the densest water (4C (39F)) sinks to the bottom, and the less dense water (water that is approaching the freezing point) rises to the top. Knowing the general properties of ocean layers will make some of the information in the lessons about One result of this stability is that as the summer wears on, there is less and less oxygen below the thermocline as the water below the thermocline never circulates to the surface and organisms in the water deplete the available oxygen. Thermocline formation is prolonged in tropic conditions, variable in temperate conditions, and very rare in cold conditions (such as those at the poles). Below the thermocline is the deep ocean. Thermoclines in the ocean are best developed at ________. Beyond a certain point, there is no sunlight, and marine life has no use for eyes. Equatorward subduction beneath the less dense surface waters results in the export of DOC . high latitudesIn general the water of the greatest density is formed in high latitudes and because this water sinks and fills all ocean basins the deep and bottom water of all oceans is cold. These different water bodies have unique phenomena, ranging from the extreme salinity in the Dead Sea to the killer jacuzzi pools in the Gulf of Mexico. The complexities of operating an OTEC plant in deeper water may make them more expensive than land-based approaches. We observe how thermoclines and the varying temperature conditions have forced organisms to evolve in a variety of ways. What is the thermocline what causes the development of a thermocline? Actual turbine work WT = (H3-H5,s) x polytropic efficiency. rising sea level fills valley with lake gigantic lake forms behind an active fault block mountain advancing ice sheet forces water out of river. []Here are four pieces of news from China Daily.SHANGHAI-The Huachen Group, which has put 83 million yuan in the development of the e-commerce market since its official registration late last year, recently held a meeting in Shanghai to show the use of its newly opened tourism business payment network. oscillate. A rapid change in density with depth in the ocean is called the _____. B. higher longitudes. KOYO USA was established in 2002 to capitalize on this new economic opportunity. In 2002, India tested a 1 MW floating OTEC pilot plant near Tamil Nadu. Deep-ocean water can be combined with surface water to deliver water at an optimal temperature. In the oceans the temperature difference between surface and deep water is greatest in the tropics, although still a modest 20 to 25C. has a craniotomy and is admitted to ICU postoperatively. [80] Another system patented by Richard Bailey creates condensate water by regulating deep ocean water flow through surface condensers correlating with fluctuating dew-point temperatures. In November, 2010 the U.S. Show the details. Depending on the latitude and season, thermoclines can be present or absent and vary in depth of occurrence, however a . 1 Which sea has the highest salinity in the world? The main characteristics of this region are the complete lack of sunlight, cold temperatures, and extremely high pressures. Cold water, pumped through a second heat exchanger, condenses the vapor into a liquid, which is then recycled through the system. 4. Realizing the need for larger partners to actually commercialize OTEC, Makai approached Lockheed Martin to renew their previous relationship and determine if the time was ready for OTEC. deep oceans T QUESTION 33 Thermoclines in the ocean are best developed at lower tropical) latitudes True False QUESTION 34 the formation that develop to the cup we called . = Earths oceans, covering over 75% of our planets surface area, include a wide variety of natural phenomena. The Mediterranean Sea is a marine biodiversity hot spot. Your email address will not be published. Thermoclines in the ocean are best developed at ________. One way that OTEC systems can avoid some of the problems and expenses of operating in a surf zone is by building them just offshore in waters ranging from 10 to 30 meters deep (Ocean Thermal Corporation 1984). This stems from a discontinuity in the acoustic impedance of water created by the sudden change in density. A hydrometer set consists of a cylinder a hydrometer a thermometer and a temperature-salinity-density or TSD graph. Experiments simulating conditions in the warm water intake pipe indicated about 30% of the dissolved gas evolves in the top 8.5 meters (28ft) of the tube. This causes a reversal or mixing between the 2 layers, with the now colder surface water sinking to the bottom. e^z/(z-i). Q. Thermoclines in the ocean are best developed at _____. How do the protagonist assert conflicts and resolutions on the hierarchical state of affairs of the country. [Solved] Thermoclines in the ocean are best developed at . [Solved] Thermoclines in the ocean are best developed at ________. m Since the intensity falls exponentially with depth y, heat absorption is concentrated at the top layers. The remaining water is saturated and is discharged to the ocean in the open cycle. r We review their content and use your feedback to keep the quality high. They patented their new "closed cycle" design in 1967. Between 25 and 35 latitude, salinity is likely to be_______. Desalinating seawater near the sea floor lowers its density, which causes it to rise to the surface. an atmosphere) Many normally could not survive in Hawaii or at Keahole Point. to complete the final design phase of a 10-MW closed cycle OTEC pilot system which planned to become operational in Hawaii in the 2012-2013 time frame. [62] Why is the thermocline important for marine productivity? Another problem that arises with having an abrupt density and temperature gradient is that thermoclines create a negative sound speed gradient. Intra-region mixing occurs, but the cline prevents the water from mixing between the 2 regions. [98] In 2011 a biological component was added to the hydrodynamic computer model to simulate the biological response to plumes from 100 megawatt OTEC plants. Weather and waves destroyed it before it could generate net power. Because the warm water is exposed to the sun during the day, a stable system exists and very little mixing of warm water and cold water occurs, particularly in calm weather. e c. Tropical region have no thermocline in winter months. These fluids have low boiling points, and are therefore suitable for powering the system's generator to generate electricity. Now consider the thermocline, which also has a density gradient. Later Dr. Bharathan worked with a team of engineers at the Pacific Institute for High Technology Research (PICHTR) to further pursue this design through preliminary and final stages. The high-pressure, high-temperature gas then is expanded in the turbine to yield turbine work, WT. a. Polar regions have well-developed thermoclines in winter months. Warm surface seawater is pumped through a heat exchanger to vaporize the fluid. Salinity in the ocean is highest in regions______is high and_____is low. 15 terms. Contents. 2003-2023 Chegg Inc. All rights reserved. A gradiant of distinct temperature differences associated with depth. Ocean Thermal Energy Conversion (OTEC) uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity.OTEC can operate with a very high capacity factor and so can operate in base load mode.. Later a 100kW land based installation was studied combining land based OTEC with Desalination and Aquaculture nicknamed ODA. 3. This region has ambient temperatures ranging from 20C to 30C depending on the geographic location. Earth Sciences questions and answers. A 100MW power plant would be expected to pump on the order of 12 million gallons (44,400 tonnes) per minute. [58] On August 22, 2016, the government of the Bahamas announced that a new agreement had been signed under which the Baha Mar resort will be completed. 13. To ensure this, a wave of height h is generated at the fore of the vessel (near the bulbous bow ). [19] The Kume Island facilities use regular water cooled by Deep Sea Water in a heat exchanger run through pipes in the ground to cool soil. But what is the pelagic zone? The movement of sand parallel to the shore ________. The speed of sound is directly proportional to the temperature, i.e., waves travel slower at lower temperatures. What is the best description of thermoclines based on latitude?a. OTEC has uses other than power production. where WN = WT + WC is the net work for the thermodynamic cycle. [8] The plant was later destroyed in a storm.[9]. It is also visible in smaller bodies of water, such as lakes and deep inland seas. Thermoclines are caused by an effect called stratification in lakes. Thus the water partially flashes to steam with two-phase equilibrium prevailing. So a layer of water with higher salinity can actual float on top of water with lower salinity if the layer with higher salinity is quite a bit warmer than the lower salinity layer. [48], As with shelf-mounted plants, floating plants need a stable base for continuous operation. In the Northern hemisphere, the maximum temperatures at the surface occur through August and September and minimum temperatures occur through February and March with total heat content being lowest in March. where, y is the depth of water, I is intensity and is the absorption coefficient. But one common phenomenon that is well known and has even had its role in filmography, is ocean thermoclines. The saltiest ocean water is in the Red Sea and in the Persian Gulf region (around 40) due to very high evaporation and little fresh water inflow. Desalination is not a viable source for producing large amounts of fresh water because of _____. New York: Oxford University Press. which is the Indian ocean. Cold-water sea animals, such as salmon and lobster, thrive in this nutrient-rich, deep seawater. Beyond a certain region, fish cannot survive the different conditions and do not venture out of their pelagic zones. In 2010, Copenhagen Energy opened a district cooling plant in Copenhagen, Denmark. Which regions seawater is most likely to have the lowest salinity? Polar regions have well-developed thermoclines in winter months.b. [53], A report published by IRENA in 2014 claimed that commercial use of OTEC technology can be scaled in a variety of ways. Due to the temperature difference, the thermocline creates a density gradient between the various pelagic ocean zones. and summer, causing a turnover in the water. Systems may be either closed-cycle or open-cycle. School Georgia Institute Of Technology; Course Title EAS 2600; Type. [71] The benefits to be assessed in the USVI study include both the baseload (24/7) clean electricity generated by OTEC, as well as the various related products associated with OTEC and SWAC, including abundant fresh drinking water, energy-saving air conditioning, sustainable aquaculture and mariculture, and agricultural enhancement projects for the Islands of St Thomas and St Croix.
