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).

Climate Change and North Carolina’s Sounds and Barrier Islands

USA – January 22nd, 2013

The sea that sculpted North Carolina’s coast, from its arc of barrier islands (visible beyond Pamlico Sound, to the right), to the vast, nurturing sounds, is reshaping it once again. Water is rising three times faster on the N.C. coast than it did a century ago as warming oceans expand and land ice melts, recent research has found. It’s the beginning of what a N.C. science panel expects will be a 1-meter increase by 2100.

Rising sea level is the clearest signal of climate change in North Carolina. Few places in the United States stand to be more transformed. About 2,000 square miles of the state’s low, flat coast is 1 meter (about 39 inches) or less above water. At risk are more than 30,500 homes and other buildings.

This won’t be the work of rising water alone, but of quirks in North Carolina’s coastal topography. The flat ground means even a small increase in water level will spread far inland. The coastal plain is also sinking, the geologic legacy of the last Ice Age. Sea-level rise also magnifies two other powerful forces: erosion that gouges the coastline and the pounding of nor’easters and tropical storms (click here to read more).

USA from Pamlico Sound to Appalachian Mountains

USA – November 10th, 2012

Green sediments create swirled patterns in Pamlico Sound, North Carolina, and along the Outer Banks, the row of low, sandy barrier islands that separate the sound from the Atlantic Ocean. At 129 km (80 mi) long and 24 to 48 km (15 to 30 miles) wide, it is the largest lagoon along the east coast of the USA. Pamlico Sound is linked on the north with Albemarle Sound through Roanoke Sound and Croatan Sound (passages).

Also of interest in this image are the Appalachian Mountains, visible upon opening the full version. The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west. These alternating ridges and valleys are easily discernible as alternating brown and green lines.

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.

Pamlico and Albemarle Sounds, North Carolina, USA

USA - April 9th, 2012

Two large sounds can be seen by the Atlantic Coast of the state of North Carolina: Pamlico Sound (greenish, below) and Albemarle Sound (darker green and brown, above). Both sounds are separated from the Atlantic Ocean by the Outer Banks, a row of low, sandy barrier islands.

Pamlico Sound is the largest lagoon along the U.S. East Coast, being 129 km (80 mi) long and 24 to 48 km (15 to 30 miles) wide. The Neuse and Pamlico rivers (the latter is the estuary of the Tar River) flow in from the west. Pamlico Sound is linked on the north with Albemarle Sound through Roanoke Sound and Croatan Sound (passages). Much of the water in the Albemarle Sound is brackish or fresh, as opposed to the saltwater of the ocean, as a result of river water pouring into the sound.
