dissolved oxygen

Dissolved oxygen is the measure of the oxygen in the water. This is important for marine animals to breathe. D.O. can get into water by waves or something that comes
in contact with the water and lets the air mix with the water. It is important to measure D.O. because we need to know how the water's oxygen trend affect the marine
animals. For example, if you have a fish in a bowl with a small opening and there is no movement on the surface of the water, the D.O. cannot mix with the air so the fish will die.

East River Background

Many people would ask what is the East River? Where is it located? Well the East River ends at South Seaport and begins at Throgs Neck Bridge. It is basically located between Manhattan,Brooklyn and Queens. Some people think that the East River is a river, but it really isnt its a strait because it dosent have a source an area where water begins to flow in the water.

When South Street Seaport was bulit over on Fulton Street and Schermerhorn Row it was the most popular place to be because of the oyster which was important in New York for example:
(1)The oyster filter the water(50gal/day).
(2)Source of food for people.
(3)Oysters are a keystone species-
important part of estuary food web.
(4)Oyster harvesting=economic porfit.
(5)Oyster reefs are shelter and sub-

(6)Oysters are yummy.

Where the East River is there use to be a Fulton Market.The first Fulton
Market open in 1822, which was part of N.Y.C early system of food distribution. When it was established in 1822, the market carried fruits, vegestables, fish and meat.

In 1811-12 the black long row was built.In 1726 Schermerhorn family began buying land. After 1793 began the filling process that created solid land from the east side of Front Street out to South Street. By 1810 the fill was complete and by 1811 half of the row has been built, the rest finished in 1812.

Where the East River is located there also a Fulton Street, which use to be a major downtown thouroughfare in the nineteenth century. Before the World Trade Center was built Fulton Street was the only street in lower Manhattan that run uninterrupted from the Hudson to the East River. The name Fulton Street was honor of Robert Fulton, whose stream ferryboat, the first of the Fulton Ferries, began to run between this street and Brooklyn in 1814.
