The region known as the continental margin extends from coastal plains and mountains across shorelines to shallow continental shelves and deeper continental slopes and rises. Events in this regionincluding sudden occurrences, such as landslides and tsunamis, and long-term processes, such as sedimentation and erosionhave great impacts on humans because so many people live near the coastal ocean and depend on its bountiful resources. Both terrestrial and marine processes operate in this region, making the sedimentary strata that form here an especially rich record of Earth history.
These strata and the processes that affect them are the subject of a new book, Continental Margin SedimentationFrom Sediment Transport to Sequence Stratigraphy, published by Blackwell Publishing, Ltd., for the International Association of Sedimentologists.
Released in July 2007, the new book is an outgrowth of the STRATAFORM (STRATA FORmation on Margins) program funded by the U.S. Office of Naval Research (ONR) and begun in 1994. Participants in this program, including many in the U.S. Geological Survey (USGS), sought to understand how ongoing physical and biological processes affect what gets preserved in the geologic record and, therefore, how preserved strata can be used to unravel Earth history.
"We all learned a lot from STRATAFORM," said USGS scientist Homa Lee, lead author of one of the chapters of the new book, "and we now run our own projects differently, integrating studies of processesmeasurements of current speeds and suspended sediment, for examplewith studies of the geologic recordsuch as core samples and seismic images of strata beneath the sea floor."
Like Lee, many contributors to Continental Margin Sedimentation are current or former members of the USGS Coastal and Marine Geology Program, including Mike Field (USGS Pacific Science Center), who is also one of the book's editors.
According to Field, "The volume centers on, but goes well beyond, the pioneering results of the STRATAFORM Program. Many of us in the USGS feel fortunate to have been involved with such a landmark study, guided by the vision of ONR's Joe Kravitz. Continental margins are receiving increasing attention from marine scientists and managers, and we anticipate that this book will serve as a keystone for the next level of advancement in continental-margin science."
