Impact of Tropical Storm Agnes on Chesapeake Bay. Volume 1. Summary


Book Description

The report summarizes the long-term impact Tropical Storm Agnes had on the Chesapeake Bay Region. The June 1972 storm caused severe lowerings of salinity levels in the Bay, which resulted in high mortalities of immobile estuarine and marine species. Mobile species were less affected. The floodwaters carried large amounts of nutrients and sewage into the Bay, thereby creating a public health hazard. The major geological effect was the deposition of sediment. Storm-related economic costs on the Bay Region totaled $42.7 million. Immediate costs were damages to boats and the clearing of debris. Long-term economic losses occurred to the recreation and fisheries industry.

























Historical Climate Variability and Impacts in North America


Book Description

Climatologists with an eye on the past have any number of sources for their work, from personal diaries to weather station reports. Piecing together the trajectory of a weather event can thus be a painstaking process taking years and involving real detective work. Missing pieces of a climate puzzle can come from very far afield, often in unlikely places. In this book, a series of case studies examine specific regions across North America, using instrumental and documentary data from the 17th to the 19th centuries. Extreme weather events such as the Sitka hurricane of 1880 are recounted in detail, while the chapters also cover more widespread phenomena such as the collapse of the Low Country rice culture. The book also looks at the role of weather station histories in complementing the instrumental record, and sets out the methods that involve early instrumental and documentary climate data. Finally, the book’s focus on North America reflects the fact that the historical climate community there has only grown relatively recently. Up to now, most such studies have focused on Europe and Asia. The four sections begin with regional case studies, and move on to reconstruct extreme events and parameters. This is followed by the role of station history and, lastly, methodologies and other analyses. The editors’ aim has been to produce a volume that would be instrumental in molding the next generation of historical climatologists. They designed this book for use by general researchers as well as in upper-level undergraduate or graduate level courses.
