Jackson Estuarine Laboratory

Jackson Estuarine Laboratory

 
Jackson Estuarine Laboratory (JEL) is located five miles from the Durham campus on the shores of Great Bay Estuary, one of the largest estuaries in northern New England. JEL features well-equipped facilities where scientists conduct field-based and experimental research on physical and biological components of coastal ecosystems. Research at JEL has advanced our understanding of coastal ecosystems, especially with regard to human influences and management, in New Hampshire, the Gulf of Maine region and the world. In a typical year, 25 projects are carried out by the scientists at JEL, with total external funding often exceeding $2 million. In 2015, The New Hampshire chapter of the Nature Conservancy named JEL its Restoration Parner of the Year!

JEL has eight resident faculty members from the departments of Biological Sciences, Natural Resources, and Earth Systems Science, along with several support staff, research associates, students, post-doctoral fellows and visiting scientists. In addition, non-resident faculty and students from other UNH departments conduct research at JEL. A fleet of small research vessels is based at JEL, including five outboard powered boats ranging from a 12-foot skiff to a 22-foot center console. Facilities include a pier with a 2,000-pound crane and a floating dock with slip spaces for four boats. JEL has a full analytical laboratory to study water quality, and labs dedicated to sedimentology, animal physiology and behavior, shellfish/seafloor ecology, microbiology, phycology (study of benthic algae), tidal marsh ecology, and seagrass ecology. In addition, flowing estuarine water is provided to a wet lab, greenhouse, and outdoor facilities to support the study of estuarine plants and animals.
