Harmful Algal Blooms and Drinking Water in Oregon

The occurrence of toxic blue-green algae causes harmful algal blooms in lakes, reservoirs, and rivers and is a growing threat to public health, with human and animal illness and death reported in at least 43 states.

Beach-dependent Shorebirds

Policy-makers, individuals from government agencies, and natural resource managers are under increasing pressure to manage changing coastal areas to meet social, economic, and natural resource demands, particularly under a regime of sea-level rise. Scientific knowledge of coastal processes and habitat-use can support decision-makers as they balance these often-conflicting human and ecological...

Ecosystem Effects of Increased Coal Transport Across the Pacific Northwest

Proposed new coal export terminals in Washington and Oregon could increase rail traffic through the Northwest and potentially increase unintended release of coal dust to the environment.

Wildlife Toxicology

The team's long term goal is:

  • Examine the causes, fates, exposures, biological accumulation, and adverse effects (including sublethal effects) of environmental contaminants on animal (largely bird) populations.

Coral Reef Ecosystem Studies (CREST)

The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

Harmful Algal Blooms (HABs)

The USGS collaborates with local, state, federal, tribal, university, and industry partners to conduct the science necessary to understand the causes and effects of toxic HABs and inform water management and public health decisions. USGS is characterizing the life cycle of HABs, their asociated toxins, and the genes responsible for cyanotoxin production. This work is enhancing the ability of...

Modeling summer month hydrological drought probabilities in the United States using antecedent flow conditions

Climate change raises concern that risks of hydrological drought may be increasing. We estimate hydrological drought probabilities for rivers and streams in the United States (U.S.) using maximum likelihood logistic regression (MLLR). Streamflow data from winter months are used to estimate the chance of hydrological drought during summer months. Daily streamflow data collected from 9,144...

Monitoring High-Priority Stream Crossings Along Proposed Natural Gas Pipeline Routes

The U.S. Geological Survey (USGS), in cooperation with the Virginia Department of Environmental Quality (DEQ), is monitoring the water quality of multiple high-priority streams where natural gas pipeline crossings have been proposed. The purpose of the monitoring effort is to collect baseline water-quality data and, if the pipeline construction is approved, to monitor water quality in these...
