Maryland's Marine Mammal and Sea Turtle Stranding Response Program was formed in 1990 following the stranding of a bottlenose dolphin in the northern reaches of the Tuckahoe River. Stranding staff respond to marine mammals and sea turtles in Maryland waters including both the Chesapeake Bay and the Atlantic Ocean.
The Maryland Department of Natural Resources partners with The National Aquarium Animal Rescue - Marine Animal Rescue Program to coordinate stranding response. This program responds to all marine mammals and sea turtles that strand alive, while the department responds to the dead strandings. Another response partner is the Smithsonian Institution. The osteo-prep lab staff at the Smithsonian Museum Support Center assists with the response and receives skeletal specimens of rare species after the necropsy exam.
The Maryland Department of Natural Resources Stranding Response Program operates out of the Cooperative Oxford Laboratory in Oxford, Maryland. The Marine Mammal and Sea Turtle Stranding Program is part of the Fish and Wildlife Health Program which monitors and investigates fish and wildlife mortality throughout Maryland.

Species of marine mammals that have stranded in Maryland since 1900:
The most commonly stranded toothed whale, or odontocete, in Maryland is the bottlenose dolphin (Tursiops truncatus). The most commonly stranded baleen whale, or mysticete, is the humpback whale. The most commonly stranded seal, or pinniped, is the harp seal. Marine mammals strand for a variety of reasons including old age, disease, major trauma (vessel strike), predation, entanglement in fishing gear, and parasitism. On average, 15 marine mammals strand each year. Most strandings occur on the Atlantic Ocean coast.
Marine mammals tend to strand seasonally based on the species and its range. For example, the harbor porpoise tends to strand in the late winter or early spring, while the bottlenose dolphin tends to strand in late spring, summer, and early fall. Seals tend to be in Maryland during the winter.
Marine Mammals are protected by law under the Marine Mammal Protection Act which prohibits the "taking" of marine mammals in all US waters. A "take" is defined as "to harass, hunt, capture, kill, or feed any marine mammal". Marine mammals are still protected under these laws even after their death. Collecting dead marine mammal remains is also considered a "take". Violations of the Marine Mammal Protection Act can result in hefty fines, imprisonment, or the seizure of vessels and personal property.

Species of sea turtles that have stranded in Maryland since 1991:
The most commonly stranded sea turtle in Maryland is the loggerhead sea turtle (Caretta caretta). The largest sea turtle in the world is the leather back, which can weigh up to 1 ton (2,200 pounds). On average Maryland has 25 dead sea turtles strandings each year. Most strandings occur along the Atlantic Coast, however, sea turtles have stranded as far north as the Magothy River in the Chesapeake Bay.
Each year, when water temperatures warm, sea turtles visit the Chesapeake Bay and water's off Maryland's coast. Sea turtles eat a variety of prey found within our waters including jellyfish, horseshoe crabs, crabs, and whelks. Individuals often return to the same feeding grounds each year and in between nesting periods.
Sea turtles strand due to a variety of natural and human causes. Natural causes of stranding or death can be due to old age, disease, predation, and cold stunning (hypothermia). Human induced strandings can be caused by hunting, boat strikes, fishing gear entanglement, and habitat degradation.
Sea turtles are protected under the Endangered Species Act (1973) and Maryland Non-Game and Endangered Species Conservation Act (1975). Sea turtles are still protected under these laws even after their death. Collecting dead sea turtles remains is also considered a violation. Violations of these laws can result in hefty fines, imprisonment, or the seizure of vessels and personal property.
