This investigation was conducted to determine the mortality rate due to drownings in Mississippi from 1992-1994. Drownings were defined as unintentional deaths from asphyxia while submerged or within 24 hours of submersion. Death certificate data including ICD-9 codes related to drownings, were received from the Mississippi State Department of Health. Variables assessed included age, age category, sex, race, death month, death day, place of drowning, and risk factors. Although drownings occurred in ages from 0-91 years, the highest mortality rates were found in the 14-17 year old age category (1 1.9 deaths per 100,000). Asian and Native American populations had the highest drowning mortality rates (23.6 and 22.6 per 100,000) when analyzed by race. However, this may be primarily due to lower populations. Males drowned five times more frequently than women. This is felt to be related to increased exposure. More drownings occurred on Saturdays and Sundays; and in the months of July, June; May, April, September, and August consecutively. Results presented here identify correlates of drowning fatalities which will enable strategic targeting of prevention programs and resources.

Coastal marshes are threatened by relative sea-level (RSL) rise, yet recent studies predict marsh survival even under the high rates of RSL rise expected later in this century. However, because these studies are mostly based on short-term records, uncertainty persists about the longer-term vulnerability of coastal marshes. We present an 8500-year-long marsh record from the Mississippi Delta, showing that at rates of RSL rise exceeding 6 to 9 mm year, marsh conversion into open water occurs in about 50 years.

In the United States during 1999-2012, about 4 per cent of adults wore life jackets while engaged in recreation on powerboats. Educational campaigns have promoted life jacket use. Mandatory use regulations target primarily children or boaters on personal watercrafts or water skiing.

Restoration of river deltas involves diverting sediment and water from major channels into adjoining drowned areas, where the sediment can build new land and provide a platform for regenerating wetland ecosystems. Except for local engineered structures at the points of diversion, restoration mainly relies on natural delta-building processes. Present understanding of such processes is sufficient to provide a basis for determining the feasibility of restoration projects through quantitative estimates of land-building rates and sustainable wetland area under different scenarios of sediment supply, subsidence, and sea-level rise.

Objective: Hurricane Katrina struck the US Gulf Coast on August 29, 2005, causing unprecedented damage to numerous communities in Louisiana and Mississippi. Our objectives were to verify, document, and characterize Katrina-related mortality in Louisiana and help identify strategies to reduce mortality in future disasters.
Methods: We assessed Hurricane Katrina mortality data sources received in 2007, including Louisiana and out-of-state death certificates for deaths occurring from August 27 to October 31, 2005, and the Disaster Mortuary Operational Response Team's confirmed victims' database.

Objective: To review injuries associated with falls from river tree rope swings (RTRS) and identify points of action for prevention.
Methods: This study was a retrospective analysis of injury reports directly related to falls from RTRS. Case reports for 2002-06 were extracted from the National Electronic Injury Surveillance System (NEISS), US legal literature, and news reports.
