The water cycle diagram, especially made for school-aged kids.
April 14, 2016

Learn about water! As part of the USGS's Water Science School, we have created a water-cycle diagram for schools and "kids" of all ages, from 5-105. Our diagram is available in over 20 languages. We also offer an interactive diagram which...

Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.

Devastation of the coastal city of Banda Aceh, Indonesia, after the 2004 Indian Ocean tsunami.
April 13, 2016

We study the distribution and hazard potential of coastal and submarine events such as earthquakes and submarine landslides and associated tsunami potential, hurricane induced coastal inundation, extreme storms, sea-level rise and oil and gas spills. We also model development to help evaluate and forecast coastal hazard probability and occurrence.

Methane hydrate
April 13, 2016

Our scientists conduct research studies focused on geologic mapping, sampling and understanding of mineral and energy resources and studies of the geologic setting and processes to inform renewable energy development offshore.

crustose coralline algae
April 13, 2016

We bring together multidisciplinary expertise focused on developing tools and models to improve understanding of how healthy ecosystems function as well as how they respond to environmental changes and human impacts including ecosystem restoration. Research studies address coral reef, coastal wetland, benthic habitat and groundwater resources.

Rookery Bay NERR, FL, USA

Hydrologic restoration is one of several approaches to rehabilitate mangroves on a large-scale. USGS evaluates how solely restoring tidal hydrologic flows affect the recovery of mangroves in Florida. ...

Figure 1. Major study areas of the TFFW vegetation modeling system (Krauss et al., 2009)
April 8, 2016

As tidal freshwater forested wetlands - TFFWs - are influenced by salinty due to salt water intrusion, they may experience changes in plant community composition, growth, and productivity. Models are needed to predict vegetation community change or dieback, as well as changes in carbon sequestration and storage due to changing climate, drought, changes in freshwater discharge, elevated carbon...

Millions of landbirds migrate through the Gulf of Mexico
April 8, 2016

USGS uses weather surveillance radar data and landscape-scale habitat metrics to model bird-habitat connections along the western coast of the Gulf of Mexico.

Sampit River, SC, USA
April 8, 2016

Tidal freshwater forested wetlands - TFFWs - can be found in the upper intertidal areas of many estuaries and act as a transition between coastal marshes and bottomland hardwood wetlands. However, it is because of their location that makes them vulnerable to sea-level rise, and they are constantly transitioning to different wetland types. USGS addresses how various processes are affected in...

Illustration of two sites with marked differences in hydrology and nutrient concentrations

USGS research in the Florida Everglades will provide information on how environmental conditions and disturbances impact carbon storage in mangrove systems.

Coastal wetlands provide valuable ecosystem services such as wave attenuation, surge reduction, carbon sequestration, wastewater treatment, and critical habitats for endangered fish and wildlife species. However, wetland loss threatens the capacity of coastal wetlands to provide these ecosystem services.

The CRMS design includes a suite of sites that encompass a range of ecological conditions across the coast
April 7, 2016

The Coastwise Reference Monitoring System was designed to monitor the effectiveness of restoration actions at individual sites, as well as across the entire Louisiana coast. ...
