The Chesapeake Bay watershed, or draingage basin, encompasses six states - New York, Pennsylvania, West Virginia, Maryland, Delaware, Virginia, and the District of Columbia. A drainage basin is a giant system of creeks, streams, and rivers that all flow into a common outlet, which in this case is the Chesapeake Bay.

Releases of oil and gas wastewaters can have complex effects on stream-water quality and downstream organisms, due to sediment-water interactions and groundwater/surface water exchange.

Emma has collaborated with multiple agencies and stakeholders to capture and translocate 30 beavers that would otherwise have been euthanized. Emma is pleased that she, along with the beavers, is assisting in conservation and restoration efforts in a sensitive arid system.

Josh’s passion for wildlife and photography have blended well, as his photographs have been published in various outlets and displayed at several galleries. Notably, one of his photographs was selected by a National Geographic editor as a “Top Photo” during the 2017 nature photographer of the year competition.

This radiograph, or x-ray, is of a bald eagle that had ingested lead. The cluster of bright white spots in its gut are lead shotgun pellets eaten by the eagle.

This deer was shot with a lead bullet. The bright white spots scattered throughout its body are fragments of lead from that bullet. These fragments can be eaten by scavengers, such as eagles, when they feed upon a gut pile or carcass left out in the field.
