Winter Lecture: The Ecological History of the Chesapeake Bay

A discussion of how fossil pollen, macrophytes, diatoms, and dated sediment cores are used to study the history of the estuary. Annapolis Maritime Museum.

Date(s):

Thursday, January 18, 2018 7:00 pm
Thursday, January 18, 2018 (7:00 pm - 8:30 pm)

Overview:

Fossil pollen, macrophytes, and diatoms, along with dated sediment cores collected from the Chesapeake Bay, are used to study the history of the estuary. Change in the estuarine system from benthic (bottom-dwelling) to pelagic (open water) as the result of the transformation of the watershed from forest to agricultural fields beginning with European colonization. Large organisms that contributed to a highly productive economy, such as the oyster, shad, and striped bass have been replaced by smaller organisms with shorter life cycles such as microorganisms, small unicellular algae, and protozoa. Presented by Grace Brush, a paleoecologist and Professor of Ecology in the Department of Environmental Health and Engineering at the Johns Hopkins University.
