Mississippi Delta Management Systems Evaluation Areas (MDMSEA)
The Mississippi Delta Management Systems Evaluation Areas (MDMSEA) Project began in 1995 with two purposes: 1) to assess how agricultural activities affect water quality; and 2) to evaluate Best Management Practices (BMPs) that mitigate agricultural nonpoint source pollution. The project is located in the northwestern portion of Mississippi, an area of intense agriculture referred to as the...
Arkansas Water Use Program
In 1977, the Congress of the United States recognized the need for uniform, current, and reliable information on water use and directed the U.S. Geological Survey to establish a National Water-Use Information Program (NWUIP) to complement the Survey's data on the availability and quality of the Nations water resources. Since 1985 site-specific water-use data for several categories have been...
Encylopedia of Caves
For many people, a visit to a cave is a wondrous event directing our minds to ponder the mysteries presented by these unique places and inspiring questions: How old is the cave? What was the role of water in forming the cave and where did the water come from? How is the cave connected to the surface environment? These are intriguing questions to...

Revisions to suspended-sediment concentration, percent smaller than 0.063 millimeter, and instantaneous suspended-sediment discharge reported for a cooperative program between the U.S. Geological Survey and the U.S. Army Corps of Engineers in the lower Mississippi-Atchafalaya River Basin, October 1989 to February 2015
This report presents revised results for four parameters reported for suspended-sediment samples that were collected in the lower Mississippi-Atchafalaya River Basin as part of a cooperative program between the U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District and the U.S. Geological Survey (USGS). The cooperative...
Norton, Katherine K.; Olsen, Lisa D.; Baumann, Todd E.; Simmons, Lane B.; Clark, Athena P.; Demcheck, Dennis K.; Johnson, Marlon Linking management planning for coastal wetlands to potential future wave attenuation under a range of relative sea-level rise scenarios
Understanding changes in wave attenuation by emergent vegetation as wetlands degrade or accrete over time is crucial for incorporation of wetlands into holistic coastal risk management. Linked SLAMM and XBeach models were used to investigate potential future changes in wave attenuation over a 50-year period in a degrading, subtropical wetland and...

Monitoring live vegetation in semiarid and arid rangeland environments with satellite remote sensing in northern Kenya
As part of the U.S. Department of the Interior’s (DOI) commitment to provide technical assistance to the Kenyan Northern Rangelands Trust (NRT), the U.S. Geological Survey, in collaboration with the DOI International Technical Assistance Program and the U.S. Agency for International Development’s regional mission in East Africa, created a high...
Rangoonwala, Amina; Ramsey III, Elijah W. Eradication of two non-native cichlid fishes in Miami, Florida (USA)
The proliferation of non-native fishes in Florida is a serious problem, and new species continue to be introduced to the state. Fishes in the Family Cichlidae have been especially successful colonizers of south Florida freshwater habitats. Herein we report a multi-agency effort to eradicate two non-native cichlid fishes in Miami, Florida (Bay...
Schofield, Pamela J.; Jelks, Howard L.; Gestring, Kelly B. Global patterns of tree stem growth and stand aboveground wood production in mangrove forests
Mangrove forests provide important ecological and economic services including carbon sequestration and storage. The conservation and restoration of mangroves are expected to play an important role in mitigating climate change, and understanding the factors influencing mangrove stem growth and wood production are important in predicting and...

Flood-inundation maps for the Amite and Comite Rivers from State Highway 64 to U.S. Highway 190 at Central, Louisiana
Flood-inundation maps for a 14.5-mile reach of the Amite River and a 20.2-mile reach of the Comite River from State Highway 64 to U.S. Highway 190 were created by the U.S. Geological Survey (USGS) in cooperation with the City of Central, Louisiana. These maps, which can be accessed through an interactive mapper at the USGS Flood Inundation Mapping...
Storm, John B. Jump-starting coastal wetland restoration: A comparison of marsh and mangrove foundation species
During coastal wetland restoration, foundation plant species play a critical role in creating habitat, modulating ecosystem functions, and supporting ecological communities. Following initial hydrologic restoration, foundation plant species can help stabilize sediments and jump-start ecosystem development. Different foundation species, however,...

The use of national datasets to produce an average annual water budget for the Mississippi Alluvial Plain, 2000–13
OverviewWater is a critically important resource for the Mississippi Alluvial Plain (MAP) region, supporting a multibillion-dollar agricultural industry. There are concerns that continued withdrawals of groundwater for irrigation may decrease future water supplies. The U.S. Geological Survey has a history of conducting research in the MAP region...

Preliminary stage and streamflow data at selected U.S. Geological Survey streamgages in New England for the floods of April 2019
The combination of rainfall and snowmelt in northern New England and rainfall in southern New England resulted in minor to major flooding from April 15 to 24, 2019, according to stage and streamflow data collected at 63 selected U.S. Geological Survey (USGS) streamgages. A typical USGS streamgage measures and records stream stage and estimates...
Kiah, Richard G.; Smith, Brianna A.; Stasulis, Nicholas W. In ovo exposure to brominated flame retardants Part II: Assessment of effects of TBBPA-BDBPE and BTBPE on hatching success, morphometric and physiological endpoints in American kestrels
Tetrabromobisphenol A bis(2,3-dibromopropyl ether) (TBBPA-BDBPE) and 1,2-bis(2,4,6-tribromophenoxy)ethane (BTPBE) are both brominated flame retardants (BFRs) that have been detected in birds; however, their potential biological effects are largely unknown. We assessed the effects of embryonic exposure to TBBPA-BDBPE and BTBPE in a model avian...
Eng, Margaret; Karouna-Renier, Natalie K.; Henry, Paula F. P.; Letcher, Robert J.; Schultz, Sandra L.; Bean, Thomas G.; Peters, Lisa E.; Palace, Vince P.; Williams, Tony D.; Elliott, John E.; Fernie, Kim J. Success of lake restoration depends on spatial aspects of nutrient loading and hydrology
Many aquatic ecosystems have deteriorated due to human activities and their restoration is often troublesome. It is proposed here that the restoration success of deteriorated lakes critically depends on hitherto largely neglected spatial heterogeneity in nutrient loading and hydrology. A modelling approach is used to study this hypothesis by...

The 350 employees of the U.S. Geological Survey’s Mid-Continent Mapping Center, U.S. Department of the Interior, received Vice President Al Gore’s Hammer Award in Rolla on September 4. The Mid-Continent Mapping Center employees were honored for their team-based approach to streamlining operations and making them more responsive to customers.
A minor earthquake with a preliminary estimated magnitude of 3.5 occurred in Clarke County, Mississippi, at 8:15 local time (9:15 EST) on March 25, according to the U.S. Geological Survey.
Patterns of sediment deposition near the mouth of the Mississippi River, traveling tar balls and the evolution of ancient marine lobsters into today’s Louisiana crayfish are a sampling of some of the earth-science topics that will be presented by scientists from the U.S. Geological Survey during a national science meeting in New Orleans next week.
Dr. Max M. Ethridge has been appointed Chief of the U.S. Geological Survey’s Mid-Continent Mapping Center in Rolla, Missouri.
