Nós realizamos um workshop com o objetivo de produzir um Boletim (Score Card) para a Baía de Guanabara e sua bacia hidrográfica. Essa newsletter resume as discussões que aconteceram entre um grupo de cientistas sociais e ambientais, engenheiros e representates do governo, reunidos para desenvolver um esboço preliminar dos indicadores e regiões a serem reportadas para a avaliação da Baía de Guanabara e sua bacia hidrográfica.

2015 Chester River Report Card

22 April 2016

In 2015, the Chester River received an overall grade of C+. CRA's Chester River Report Card is the product of tremendous volunteer effort and scientific analysis. The Chester Tester Citizen Scientists collect data at 27 stream sites twice monthly, year round. Our Riverkeeper and Watershed Manager collect samples from the mainstem of the Chester River from Eastern Neck Island to Crumpton.

23 March 2016

New York Harbor is a large, iconic and complex body of water. The harbor is an important part of New York City and its millions of residents, and has been massively changed by human activities. These changes have altered the shorelines, water flow, plants and animals of the harbor. These drawings of New York Harbor help explain what is happening below the water surface—a look inside.

Ecological restoration of the Chesapeake through the Chesapeake Bay total maximum daily load (TMDL) requires the reduction of nitrogen, phosphorus, and sediment loads in the Chesapeake watershed because of the tidal water quality impairments and damage to living resources they cause. Within the Chesapeake watershed, the Conowingo Reservoir has been filling in with sediment for almost a century and is now in a state of near-full capacity called dynamic equilibrium.

George Washington Memorial Parkway was developed as a scenic parkway to help preserve the Potomac River Gorge and shoreline while serving as a memorial to the first President of the United States, George Washington. The Potomac Gorge is one of the most significant natural areas in the United States, and is home to more than 400 occurrences of over 200 rare species and communities.

Long-Term Changes in Sediment and Nutrient Delivery from Conowingo Dam to Chesapeake Bay: Effects of Reservoir Sedimentation (Page 1)

Long-term changes in sediment and nutrient delivery from Conowingo Dam to Chesapeake Bay: Effects of reservoir sedimentation

Zhang Q, Hirsch RM, Ball WP ·
2016

Reduction of suspended sediment (SS), total phosphorus (TP), and total nitrogen is an important focus for Chesapeake Bay watershed management. The Susquehanna River, the bay’s largest tributary, has drawn attention because SS loads from behind Conowingo Dam (near the river’s mouth) have been rising dramatically. To better understand these changes, we evaluated histories of concentration and loading (1986−2013) using data from sites above and below Conowingo Reservoir.

This book highlights perspectives, insights, and data in the coupled fields of aquatic microbial ecology and biogeochemistry when viewed through the lens of collaborative duos – dual career couples. Their synergy and collaborative interactions have contributed substantially to our contemporary understanding of pattern, process and dynamics. This is thus a book by dual career couples about dual scientific processes.
