  5. MARITIME ZONES BASELINE: Normally it is the low-water line of the coast but if the coastline is deeply indented, straight baselines can be used INTERNAL WATERS: Covers all water and waterways which are located on the continental side of the baseline TERRITORIAL WATERS: The coastal state laws applies within the limit of 1 2 nautical miles from the baseline which is known as Territorial Waters CONTIGUOUS ZONE: It exists beyond Territorial waters upto 12 nautical miles. This is zone where Customs, Migration, Taxation and Pollution laws could be applicable by the coastal state ARCHI PELAGIC WATER: Archipelagic states have sovereignty over an area of sea, enclosed by straight line drawn connecting outermost point of island

This is the area where coastal area has exclusive rights to explore all natural resources. CONTINENTAL SHELF: It has been defined as the natural prolongation of the land territory to the continental margin's outer edge or 200 nautical miles from baseline, whichever is greater HIGH SEA: All parts of the sea that are not included in Exclusive Economic Zone, Territorial Zone or in internal waters of the State INTERNATIONAL SEA BED: Seabed and ocean floor beyond the limits of jurisdiction of a nation

  9. TYPES OF MARINE POLLUTION ACIDIFICATION-Increase in Carbon Dioxide in air is making oceans more acidic EUTROPHICATION-Increase in compounds, mainly of nitrogen or phosphorus which increases the primary productivity of the ecosystem MARINE DEBRIS-Eighty percent of marine debris is plastic which is discarded mainly by anthropogenic activities TOXIC SUBSTANCES-There are persistent addition of such toxic substances to oceanic water which do not degrade at a faster rate which includes mercury, lead, arsenic, nickel and cadmium NOISE POLLUTION-This could be result of ships, oil exploration, seismic surveys or due to sncbudnnetrrsenic water which de not degrade at a faster rate which sonar.
