Specific reasons for leaving England had its respective colonies to travel to. In addition, oyster aquaculture continues to thrive, providing both ecological and economic benefits to the region.

The social structure and family life of the two colonies varied greatly. The Chesapeake Bay is what is known as a watershed, an area that contributes to the drainage to a water body, stream, river, lake or ocean.

For one, they date from the archeological site because of adjacent artifacts that correspond with a specific time. I have some proposals. They were the ones who left the notes. The opportunity to act is right where anyone stands and the closest one to this area is known as the Chesapeake Bay watershed. Though nitrogen is necessary for life and a healthy part of coastal waterways, too much nitrogen changes the ecosystem. The extra nutrients cause a chain reaction that eventually kills most of the organisms in that area. But first, why did the British come? Prior to substantial human activity in the region, most nitrogen and phosphorus was absorbed or retained by natural forest and wetland vegetation. For this reason, the northern New England colonies and the southern colonies like Virginia and Maryland in the Chesapeake bay area started to establish ways of life that began to develop very different lifestyles. Travel is also a major reason people embark upon the Bay with its easy access to various locations. Nitrogen and phosphorus have always been a part of the Chesapeake Bay ecosystem, but have increased to excessive levels over the last few decades. During colonization, two regions were formed, New England and the Chesapeake Bay area. Using shells collected during archeological digs by the Smithsonian Institution dating from roughly to , Black compared the ratios of nitrogen isotopes stored in the shells with modern shells harvested near a dock at the Smithsonian Environmental Research Center in Edgewater, Maryland.

This is what is known as a dead zone. Adults who migrate into the Bay each spring have declined recently causing concern, but overall reproduction has been consistent. Focused on restoring two of the Bay's most effective natural filters—trees and oysters—the campaign will improve water quality, engage new advocates, and drive economic benefits across the region.

In the period termed pre-contact the indigenous peoples living in the Chesapeake Bay region were known collectively as the Powhatan people. Lambert, T. Spanning lengths over , meters, this it is a watershed that extends over six states, the District of Columbia, and meets the needs of over 15 million individuals. That's what happened in the summer of , with record rainfall levels resulting in the phosphorus, nitrogen, and water clarity scores dropping. What else they did was good was that they were able to capture Chesapeake Bay to totally surround Cornwallis until he rendered the surrender What the British learned was to factor in the weather when they are trying to retreat as well as never underestimate your opponent. In addition, oyster aquaculture continues to thrive, providing both ecological and economic benefits to the region. When the Europeans started harvesting oysters, they did so by scooping them up in shallow water. Even though the vast majority of land in the Chesapeake Bay watershed is nonfederal land, the same set of "proven cost-effective tools and practices that reduce water pollution" are appropriate for all land managers. Serving as a filter as it feeds, the oyster becomes a record of environmental changes by incorporating organic materials into its shell.

The results show a distinct shift in nitrogen sources between andwhich kicks off a rapid increase in nitrogen through today. As a result, the State of the Bay score fell one point to a Spanning lengths overmeters, this it is a watershed that extends over six states, the District of Columbia, and meets the needs of over 15 million individuals.

Fortunately, those losses have been somewhat offset by preservation efforts, but more needs to be done.

Taking Action: Making History The Chesapeake Bay's restoration has the potential to be the most dramatic example of environmental recovery ever seen. I began the two-mile long trek on my hands and feet and knew I would stay in this position until I reached Bay.

Another of Andrus' students performed similar work in Charleston Harbor, and results there show oysters live under similar nitrogen levels now as in prehistoric times, despite an uptick of nitrogen in the midth century, he said.
