CAMBRIDGE — Ninety-minute walking tours will take visitors through four laboratories at Horn Point Laboratory every Tuesday at 10 a.m. through the end of August. The tours will begin on May 30. Visitors will be able to tour the largest oyster hatchery on the East Coast and see the restoration efforts for Atlantic sturgeon, a once abundant fish in the Bay.

The Horn Point Laboratory (HPL) is an environmental research facility of the University of Maryland Center for Environmental Science (UMCES) the principal institution for advanced environmental research and graduate studies within the University System of Maryland. The other UMCES laboratories are the Chesapeake Biological Laboratory, in Southern Maryland, and the Appalachian Laboratory, in the mountains of Western Maryland.

Directed by Professor Michael Roman, HPL is located on the banks of the Choptank River, a tributary of the Chesapeake Bay on Maryland’s Eastern Shore. The laboratory is interdisciplinary with faculty engaged in research on the biology, chemistry, physics, and ecology of organisms and ecosystems from wetlands and estuarine waters of the Chesapeake Bay to the continental shelf and open waters of the world’s oceans.

Areas of scientific expertise include oceanography, plankton dynamics, marine macrophyte and wetland ecology, systems ecology, nutrient dynamics and eutrophication, physiological ecology of benthic invertebrates, benthic-pelagic interactions, and aquaculture. HPL is a member of the Southern Association of Marine Laboratories (SAML) and the National Association of Marine Laboratories (NAML)
