Oceanography (from the Ancient Greek ὠκεανός "ocean" and γράφω "write"), also known as oceanology, is the scientific study of the ocean. It is an important Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans including marine geology, physics, chemistry and biology.
March is a Fenland market town and civil parish in the Isle of Ely area of Cambridgeshire, England. It was the county town of the Isle of Ely which was a separate administrative county from 1889 to 1965. It is now the administrative centre of Fenland District Council.
The town grew by becoming an important railway centre. Like many Fenland towns, March was once an island surrounded by marshes. It occupied the second largest "island" in the Great Level. As the land drained, the town grew and prospered as a trading and religious centre. It was also a minor port before, in more recent times, a market town and an administrative and railway centre. March is situated on the banks of the navigable old course of the River Nene, today mainly used by pleasure boats.
