The USA touts Chesapeake Bay as its premier environmental restoration programme, yet the Bay remains in poor condition.

GARY GENTILE'S POPULAR DIVE GUIDE SERIES Over 100 GPS and loran numbers included As suggested by the title and series name, this volume covers the most well-known wrecks sunk in the Maryland portion of the Chesapeake Bay. For each of the wrecks covered, a statistical sidebar provides basic information such as the dates of construction and loss, previous names (if any), tonnage and dimensions, builder and owner (at time of loss), port of registry, type of vessel and how propelled, cause of sinking, location (GPS and/or loran coordinates if known), and depth. In most cases, an historical photograph or illustration of the ship leads the text. Throughout the book is scattered a selection of additional photographs. Each volume is full of fascinating narratives of triumph and tragedy, of heroism and disgrace, of human nature at its best and its basest. These books are not about wood and steel, but about flesh and blood, for every shipwreck saga is a human story. Ships may founder, run aground, burn, collide with other vessels, or be torpedoed by a German U-boat. In every case, however, what is emphatically important is what happened to the people who became victims of casualty: how they survived, how they died. Also included are descriptions of the wrecks as they appear on the bottom. At the end of each volume is a bibliography of suggested reading, and a list of GPS and loran numbers of wrecks in and adjacent to the area covered. Wrecks covered in Shipwrecks of the Chesapeake Bay in Maryland Waters are: Alum Chine, American Mariner (target ship), Benjamin O. Colonna, Columbia, Columbus, Dragonet (American submarine), Express, Favorite, General J.A. Dumont, Hannibal, Herbert D. Maxwell, Levin J. Marvel, Mary A. DeKnight, Medora, Nelly White, New Jersey, S-49 (American submarine), Three Rivers, Tulip (Civil War gunboat), U-1105 (German U-boat), Wawaset, and Wilson Small. Also included is a special section about shipwrecks in Curtis Bay and Mallows Bay.

Nonnative Oysters in the Chesapeake Bay discusses the proposed plan to offset the dramatic decline in the bay's native oysters by introducing disease-resistant reproductive Suminoe oysters from Asia. It suggests this move should be delayed until more is known about the environmental risks, even though carefully regulated cultivation of sterile Asian oysters in contained areas could help the local industry and researchers. It is also noted that even though these oysters eat the excess algae caused by pollution, it could take decades before there are enough of them to improve water quality.
