When fresh river water mixes with sea water in a semi-enclosed basin‚ an estuary is formed. The formation of estuaries can also occur in drowned river valleys (Owen‚ 1992‚ p.3). A variety of plant and animal species live in the estuary as they are provided with a wealth of living space‚ food and shelter. Many native flowering plants and seaweeds are included in the flora of the estuaries‚ where the plant species are distributed based on their salinity tolerances. Salt marshes form towards the high-tide

Fishing communities are commonly found along the coast of Maine. One of these is the island community of North Haven that has a year-round population of approximately 360 people. This small town revolves around the fishing season‚ whether it is selling their lobster catches to summer visitors‚ or catching shrimp throughout the winter. In recent years the water temperatures have increased due to global warming causing lobsters and other fish to migrate away from the Gulf of Maine. Ronald Wright in

The Neritic zone is also called coastal waters‚ the coastal ocean‚ and the sublittoral zone. It is the part of the ocean extending from the low tide mark to the edge of the continental shelf. It is considered a shallow depth‚ extending to about 200 meters. The Neritic zone has decently well oxygenated water‚ low water pressure‚ and fairly stable temperature and salinity levels. This is the location of most of the sea life in the ocean. Salinity is the level of salt in the water. The Neritic zone

Take-Home Quiz: Mathemafish Population Over the past year these rare Mathemafish are being threaten by the Fluted Dropout Shark. As months pass the population is starting to decrease more and more. We are finding that out through the catch-tag-release method (method that allows us to track the fish) that the past twelve months the population which started at 480 has dropped to 46. Three specific intervals were chosen because these intervals showed the most of how population changes throughout time
