Decoding the Deep Sediments: The Ecological History of Chesapeake Bay (Chesapeake Perspectives) - Tapa blanda

Sinopsis

The sediments of Chesapeake Bay harbor a record of the Bay's ecology, from its natural functioning thousands of years before European colonization through post-Colonial settlement and the continuing forest clearance throughout the watershed. Translating that record into a history of ecological change has been the focus of Grace Brusk's paleoecological research at Johns Hopkins University for more than thirty years.

In Decoding the Deep Sediments, Brush explains the nature of the studies she and her colleagues have been engaged in and how they analyze the hundreds of cores they have taken throughout the Bay. Their work has demonstrated how the cutting down of trees and large-scale land use changes have affected the Bay's ecosystem in massive runoff of sediment and nutrients, all of which have contributed to the decline of water quality. A major effect has been the shift from a Bay ecosystem once dominated by benthic processes to one now dominated by pelagic processes.

In addition to the science she has been engaged in over these years, Dr. Brush, a Mathias Medal winner, writes about how she came to do aquatic research in the first place and about the difficult challenges she and women scientists of her time had to deal with. As Maryland Sea Grant Director Fredrika Moser writes in the foreword, Grace Brush has an important story to tell: I think all readers will admire her remarkable story, her fortitude, and, not least of all, the students she has attracted to continue this work.

This book is the fifth in Maryland Sea Grant's Chesapeake Perspectives series, in which researchers, scholars, and other thinkers share their insights into the unique culture and ecology of the Chesapeake Bay.
