Book Description :

Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements. Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials—as well as environmentally hazardous materials—from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection. Coverage of measurement, mapping and profiling techniques Descriptions of technologies for remote measurement of ocean currents and their signatures Reviews crucial aspects of ocean currents, including special emphasis on the planet-spanning thermohaline circulation, known as the ocean's "conveyor belt," and its crucial role in climate change

Book Description :

A thin film thermal sensor is being developed to improve U.S. Navy capabilities for measuring ocean current profiles. Using the sensor, current velocity is determined by measuring the resistance changes in each of four platinum films positioned on the surface of the cylindrical sensor substrate. Development of this device into a practical ocean-going tool has involved overcoming substrate fragility, water leakage problems, and biofouling contamination. A high-strength ceramic substrate has been selected to improve ruggedness. New coating systems to prevent water penetration into the sensor are being developed and evaluated. An electrolytic hypochlorite generation technique has been developed to prevent biofouling indefinitely on the sensor surface. Tests have shown the sensor produces repeatable results in the laboratory and agrees well with commercial current meter measurements during ocean testing. (Author).

Book Description :

Shore-based, high frequency (HF) and very high frequency (VHF) radar systems for measuring ocean surface currents have been well detailed in the literature. The use of these systems has been limited to coastal ocean applications since both of the required radar sites must be positioned ashore. To relieve the geometric constraints imposed by two shore sites and allow coverage of more coastal areas, necessitates at least one sea-based system (Skop et al., 1994). Reducing the number of required sites to one increases the ocean area that can be measured. The feasibility of using a single, VHF radar system based on a moving ship for both near shore and deep water area coverage is the subject of this report. In December 1993 and July 1994 a near shore, ship-based data set was taken off the east coast of Key Biscayne, Florida, with overlapping coverage by a shore-based site. The July 1994 experiment also saw deep water data sets acquired as the ship described a square pattern to obtain overlapping grid coverage from the ship itself. The measurement and reduction of ship-induced contamination in the returned Doppler spectra are detailed. By combining ship and shore radial data, two vector current maps off north and south Key Biscayne a obtained. Using the same methodology, the vectorization of the deep water radials produces two more vector current maps from on transmit-receive ship-based site. The deep water surface current maps are dominated by the high speed, northerly flowing Florida Current and are quite accurate. The Key Biscayne surface current maps are less accurate, being dominated by pseudo-currents that are introduced through GPS errors in ship position. These GPS errors lead to inaccurate calculations of the ship velocity and, hence, to inaccurate removal of the ship-induce Doppler currents from the measured currents. (MM).

Book Description :

A method of measuring deep ocean currents is proposed, utilizing many one-shot explosive neutrally buoyant floats. These floats, which explode after a preset time in the water, may be located over long distances by making use of the oceanic sound channel. The useful data will consist of the mean drift for some depth range, the variance with respect to the mean drift, and a possible correlation between vertical and horizontal scatter. There are to be 20 floats deployed in a cluster around 1000 meters deep. Each float will telemeter its depth to a surface ship immediately after deployment. The floats will explode after several weeks, and the explosions will be located by hyperbolic navigation in the sound channel. This report concerns primarily the developmental aspect of the system, including the detailed design of the floats. (Author).

Book Description :

The Indian Ocean represents a part of the global Ocean that has been less studied by modern oceanography than the Atlantic and Pacific parts. This is remarkable, since the Indian Ocean was subject to much historic exploration through navigators from Asia, India, the Middle East and lastly from Europe. This unique, comprehensive reference set on the Indian Ocean, covers all oceanographical aspects with its physics, chemistry, biology and geology in 21 peer-reviewed expert-written chapters. Besides the well-ground basis on the Ocean’s characteristics and a wealth of data, some unique features presented are the monsoon - the biennial reversal of winds and the resultant surface circulation; the tropical and sub-tropical jet streams, namely the Somali current, the Agulhas current and the Leevwin current; the oxygen-poor intermediate waters in its northern part which significantly contribute several green house gases to the atmosphere, for example, carbon dioxide, nitrous oxide, methane and dimethyl sulphide; its exhaustive coral reefs and mangrove vegetation; and the polymetallic nodules at its depths and its other mineral resources. Moreover, an analysis is provided of the anthropogenic contributions and their impacts on the health of the Indian Ocean; and that of estuary environments of important rivers of the 15 littoral countries. Intended for research scientists, professionals and students working in physical, chemical and geological oceanography.
