Mineral Resource Assessment of U.S. Territories of the Caribbean Basin Archipelago including Puerto Rico, U.S. Virgin Islands and Adjacent Areas

Project objectives are to develop a modern probabilistic quantitative mineral resource assessment of Puerto Rico, U.S. Virgin Islands and adjacent geologically similar areas that examines the potential for minerals-based economic development and trade within the region.

Bird Banding Laboratory

The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America.  This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Biology, Impacts and Control of Invasive Reptiles

Invasive species are considered to be second only to habitat degradation in terms of negative impacts on the Earth’s ecosystems, and our scientists make up a significant proportion of the global expertise in the rapidly-growing problem of invasive reptiles.

Drought Conditions in Puerto Rico

A drought is a period of drier-than-normal conditions that results in water-related problems. When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If...

National Park Service Visitor Spending Effects

The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. USGS economists collaborate with the National Park Service social science program to estimate NPS...

North American Waterfowl Management Plan

The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats. Without this information, NAWMP population, habitat, and people objectives may not reflect stakeholder and societal values; and management...

Understanding Coastal Change

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.

Geologic Hazards and Catastrophic Events

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.

Connectivity of Tropical Marine Ecosystems: Understanding Biodiversity and Trophic Relationships in the Virgin Islands and Puerto Rico

Marine reserves and protected areas in the U.S. Virgin Islands and Puerto Rico encompass a variety of tropical ecosystems, including coral reefs, mangroves, and seagrass beds, but questions remain regarding how effective these areas are at preserving and protecting the habitats and species they encompass. USGS and collaborators address this question by examining the biodiversity and food web...

Although Hurricane Lenny brought high winds and heavy rains to Puerto Rico, residents in the vicinity of Lago La Plata were spared the hazards and inconveniences of an unnecessary evacuation Wednesday morning, in part because of the efforts of U.S. Geological Survey Caribbean District Office personnel in advance of, and during the storm.

Electricity may be out and communication lines cut off by the tremendous winds and torrential rains of Hurricane Georges, but thanks to good foresight in "hardening" monitoring systems by the U.S. Geological Survey, real-time streamflow data in Puerto Rico continued to flow to reservoir operators, emergency officials, and others who need streamflow information and need it fast.
