Sunglint on Bays of USA’s East Coast

USA – May 10th, 2013

Sunglint reflecting off the Atlantic Ocean highlights the contours of bays along the East Coast of the United States of America: Chesapeake Bay, Albemarle Sound and Pamlico Sound (from top to bottom).

The Albemarle-Pamlico Estuarine System is one of the largest and most important in the United States. Covering approximately 7,530 square kilometers (2,900 square miles), the waters of the system comprise the second largest estuarine system on the East Coast of the United States, exceeded in area by only the Chesapeake Bay.

The Albemarle-Pamlico Estuarine System is comprised of an extensive complex of creeks, rivers, swamps, marshes, and open water sounds dominating northeastern North Carolina. Tributaries originating in the mountains and piedmont serve as conduits from a major portion of North Carolina and southern Virginia. Albemarle Sound is the
drowned portion of the Roanoke River and its extensive floodplain.

The Coastal Plain of the Albemarle-Pamlico Region is widely recognized as among the USA’s most vulnerable landscapes to relative sea level rise and associated climate phenomena. The indicators “ambient air temperature,” “storm frequency and intensity,” and “relative sea level rise” all offer insights into the influence of climate stressors on the Albemarle-Pamlico ecosystem (click here for more information).

Bays and Cities Along USA’s East Coast

USA – October 22nd, 2012

Several important cities and state capitals can be seen as grey areas along the east coast of the United States of America. From upper right to lower left we can observe New York City, Newark, Trenton, Philadelphia, Baltimore and Washington, D.C. Sediments can be observed in Delaware Bay (between southern New Jersey and Delaware, near the image center), though fewer are visible in Chesapeake Bay (southwest of the former).

Bays and Sounds in North Carolina and Virginia, USA

USA - April 17th, 2012

Sediments cloud two large sounds by the coast of North Carolina, separated from the Atlantic Ocean by a chain of low-laying, sandy barrier islands known as the Outer Banks. The light green sound is Pamlico Sound, and the greyish brown sound above it is Albemarle Sound.

The former is the largest lagoon along the east coast of the USA, with a length of 129 km (80 mi) and a width that ranges from 24 to 48 km (15 to 30 miles). The sediments in the sound come from rivers such as the Neuse and the Pamlico.

Visible to the north of the two sounds, in the upper right quadrant, is Cape Charles, a headland in Northampton County, Virginia. It forms the northern side of the entrance to the Chesapeake Bay. Cape Henry, which forms the southern side of the entrance to the Chesapeake Bay, and Cape Charles are collectively known as the Virginia Capes.

Chesapeake Bay, the USA’s Largest Estuary – January 19th, 2012

USA - January 5th, 2012

This wide-swath ASAR image shows the Chesapeake Bay, the largest estuary in the United States. It lies off the Atlantic Ocean, surrounded by Maryland and Virginia. The Chesapeake Bay’s drainage basin covers 64,299 square miles (166,534 km2) in the District of Columbia and parts of six states: New York, Pennsylvania, Delaware, Maryland, Virginia, and West Virginia. More than 150 rivers and streams drain into the bay.

The Chesapeake Bay is approximately 200 miles (300 km) long, from the Susquehanna River in the north to the Atlantic Ocean in the south. At its narrowest point between Kent County’s Plum Point (near Newtown) and the Harford County shore near Romney Creek, the bay is 2.8 miles (4.5 km) wide; at its widest point, just south of the mouth of the Potomac River, it is 30 miles (50 km) wide. Total shoreline for the bay and its tributaries is 11,684 miles (18,804 km), and the surface area of the bay and its major tributaries is 4,479 square miles (11,601 km2). Average depth of the bay is 46 feet (14 m) and the maximum depth is 208 feet (63 m).

Bays and Sounds Along Coastal Virginia and North Carolina, USA

USA - April 15th, 2011

Several large bodies of water can be observed in this image of North Carolina (lower two-thirds) and Virginia (upper third), along the east coast of the United States of America.

At the top is part of the Chesapeake Bay is the largest estuary in the United States. It lies off the Atlantic Ocean, surrounded by Maryland (the southern tip of which is visible at the upper right) and Virginia.

Moving southward down the coast, one comes to the greyish brown Albermarle Sound, in North Carolina. Below it is the greenish Pamlico Sound, the largest lagoon along the U.S. East Coast. Both sounds are separated from the Atlantic Ocean by the Outer Banks, a row of low, sandy barrier islands.
