- Rewrite each statement correctly on the lines provided. 1. During the 1940s and 1950s, scientists began using radar on moving ships to map large areas. of the ocean floor in detail. 2. The youngest rocks are found far from the mid-ocean ridges. 3. The scientist Henry Hess invented echo-sounding devices for mapping the ocean floor. 4. As the seafloor spreads apart, hot saltwater moves upward and flows from the cracks. 5. As the new seafloor moves away from the ridge and becomes hotter, it moves upward and. forms still higher ridges. 6.

Echolocation Echolocation in Other Mammals. Dolphins and toothed whales use echolocation to orient themselves and locate objects in the water. These animals probably rely on sound production and reception to navigate, communicate, and hunt in dark or murky waters where sight is of little use.

Chronometer watch The term chronometer is also used to describe a marine chronometer used for celestial navigation and determination of longitude. The marine chronometer was invented by John Harrison in 1730. This was the first of a series of chronometers that enabled accurate marine navigation. From then on, an accurate chronometer was essential to deep sea marine or air navigation out of sight of land.

Three original Rife Machines have been found. Find out how they really worked by reading: The Rife Machine Report Below in the second chart are Dr. Rife's 1935 frequencies that were used in his Rife Ray #3 and Rife Ray #4 Rife Machines. These frequencies were read in 1935 by Dr. Rife's engineer, Philip Hoyland, from Dr. Rife's Rife Ray #3 instrument using a master oscillator.hilip Hoyland used these higher low audio frequencies so that he could hide Dr. Rife's true frequencies. The reason he had to hide Dr. Rife's true frequencies is due to the fact that Dr. Rife could not patent his Machine or his frequencies. Dr. Rife's machines were standard frequency generating equipment of his day.

Some energy may be lost in plastic deformation of the member and some may be converted into heat instead of stored as strain energy, but the rest is recoverable.A spring is an example of a storage device for strain energy.train energy is a form of potential energy. Work done to distort an elastic member is stored as strain energy.

Exploration Arguably the biggest breakthrough in petroleum and natural gas exploration came through the use of basic seismology. Seismology refers to the study of how energy, in the form of seismic waves, moves through the Earth’s crust and interacts differently with various types of underground formations. In 1855, L. Palmiere developed the first ‘seismograph’, an instrument used to detect and record earthquakes.

Vancouver, George (1758-1798) In May, Lieutenant Peter Puget, under Vancouver's orders, explored more remote western channels, while Vancouver surveyed south of Bainbridge Island's Restoration Point. George Vancouver's 1792 investigations of Puget Sound and environs were for the purpose of seeking scientific and commercial information.His principal assignment, however, was to arrange meetings with Spanish representatives in Nootka Sound on the west coast of Vancouver Island.e served for 25 years in the British Navy, and commanded the Discovery on her expedition to the North Pacific. In April 1792, George Vancouver entered the Strait of Juan de Fuca and commenced his exploration of Puget Sound. He named every island, mountain, waterway, and point of land in sight -- 75 in all.

Deep-ocean Assessment and Reporting of Tsunamis (DARTÂ®) Description System Overview. DART® systems consist of an anchored seafloor bottom pressure recorder (BPR) and a companion moored surface buoy for real-time communications (Gonzalez et al., 1998). An acoustic link transmits data from the BPR on the seafloor to the surface buoy.

Reading between the tides: 200 years of measuring global sea level Scientists are also developing GPS buoys that can measure sea levels offshore, potentially covering more of the oceans than coastlines, Gill adds. Since 1993, satellite altimeter missions have been providing highly accurate sea level measurements far out at sea, too, though their paths don’t cover polar areas, he says.

Chronometer watch The term chronometer was coined by Jeremy Thacker of Beverley, England in 1714, referring to his invention of a clock ensconced in a vacuum chamber. The term chronometer is also used to describe a marine chronometer used for celestial navigation and determination of longitude. The marine chronometer was invented by John Harrison in 1730. This was the first of a series of chronometers that enabled accurate marine navigation. From then on, an accurate chronometer was essential to deep sea marine or air navigation out of sight of land.

A history of medical imaging In the 1960's the principals of sonar (developed extensively during the second world war) were applied to diagnostic imaging. The technique is similar to the echolocation used by bats, whales or dolphins. The ultrasound scanner transmits high-frequency sound waves into a body by use of a probe or transducer.
