Referring to both the dynamic nature of the barrier islands forming the coastal lagoons of Maryland’s Atlantic Ocean coastline and also the changing cultural landscape, Shifting Sands is a richly illustrated, multi-authored introduction to Assawoman Bay, Isle of Wight Bay, St. Martin River, Sinepuxent Bay, Newport Bay, and Chincoteague Bay.

The central Kura River basin is a large river basin in the mountainous South Caucasus region of Eurasia. It contains important water resources for three countries—Georgia, Armenia, and Azerbaijan—and has a combined population of some 17 million people. There are many threats to these shared water resources, including nutrient inputs, heavy metal pollution, and sediment erosion.

Coastal lagoon ecosystems across the Delmarva Peninsula are rapidly evolving due to changing land use patterns and shifts towards intensive agriculture, particularly poultry production, and intensive rural-resi­dential development. These changes in the coastal lagoon seascape are especially evident in the northern Coastal Bays watershed of St. Martin River.

Fine scale patterns of water quality in three regions of Marylands Coastal Bays: assessing nitrogen source in relation to land use

Intensive sampling of the Maryland Coastal Bays in May and July of 2007 served to further assess spatial patterns in nutrients, responses of biological indicators, seasons, land use, and nutrient cycling. Trends indicated degraded water quality, high tubidity, increasing total nitrogen and phosphorus concentrations, high natural isotope abundance (δ15N), and low dissolved oxygen. The abundance of crop agriculture and development of the St.
