Cyanobacterial harmful algal blooms (cyanoHABs) are detrimental not only to human and ecosystem health, but also to local economies that rely on surface water for consumption, tourism, and recreation. Previous work has been done to predict cyanoHABs in Florida at the lake and sta...

Resource managers, regulators, and regulated entities need rapid, reach-scale methods to classify streamflow duration to implement and comply with many federal, state and local programs. The U.S. Environmental Protection Agency is working cooperatively with the U.S. Army Corps of...

Satellites can be used for water quality monitoring and provide social economic benefits such as early warnings related to health and cost savings. Here, we overview satellite applications for oil spill events, seagrass habitat, and harmful algal blooms. This review covers a rang...

The Cyanobacteria Assessment Network (CyAN) is a collaboration between EPA, NASA, NOAA, and USGS seeking to develop and mainstream remotely sensed satellite data products for cyanobacteria monitoring. Mobile and web apps allow lake managers and the public to view near-real-time d...

The objective of this pilot study is to evaluate whether electronic health record (EHR) systems can be used to study respiratory effects associated with exposure to aerosolized cyanobacterial toxin exposure. We aimed to evaluate if whether we can detect an increase in healthcare ...

Over half the U.S. population lives in coastal areas, including estuarine shorelines. Estuary Data Mapper (EDM; www.epa.gov/edm) continues to provide the infrastructure to support nationwide application of EPA data and tools for coastal environmental decision-making, including in...

Harmful algal blooms&nbsp;of&nbsp;cyanobacteria&nbsp;(CyanoHAB) have emerged as a serious environmental concern in large and small water bodies including many inland lakes. The growth dynamics of CyanoHAB can be chaotic at very short timescales but predictable at coarser timescal...

Harmful algal blooms caused by cyanobacteria are a threat to global water resources and human health. Satellite remote sensing has vastly expanded spatial and temporal data on lake cyanobacteria, yet there is still acute need for tools that identify which waterbodies are at-risk ...

A Seminar/Workshop was convened by the Regional Field Studies Office of the Environmental Protection Agency's Environmental Sciences Research Laboratory to provide for the exchange of research results and to discuss the state-of-the-art of instrumentation and investigative techni...

Multiple drought-related wildfires burned forests across the western United States (U.S.) during the 2020 fall season. Wildfires can significantly affect hydrologic processes such as streamflow and nutrient transport to stream, however, the natural variability of its behavior com...

This observational study gathered data from 73,425 U.S. Veterans in multiple domains including the Veterans Affairs Clinical Assessment, Reporting and Tracking (VA-CART) program, inpatient and outpatient laboratory electronic health records, and geospatial information.&nbsp; PM2....

Frequent observations of surface water at fine spatial scales will provide critical data to support the management of aquatic habitat, flood risk and water quality. Sentinel-1 and Sentinel-2 satellites can provide such observations, but algorithms are still needed that perform we...

Riparian Proper Functioning Condition (PFC) refers to a qualitative description of the potential state of a riparian ecosystem: proper functioning condition, functional-at-risk, apparent trend, or non-functional. These states are influenced by the dynamic nature of the hydrologic...

The TEMPO satellite mission, scheduled to launch in early 2023, will provide hourly to sub-hourly observations of air quality relevant pollutants (NO2, HCHO, O3, SO2, and aerosols) during daylight hours at neighborhood scales, 2 km &times; -4 km. These observations will provide a...

Tidal wetlands are valued for the ecosystem services they provide yet are vulnerable to loss due to anthropogenic disturbances such as land conversion, hydrologic modifications, and the impacts of climate change, especially accelerating rates of&nbsp;sea level rise. To effectivel...

The data supplement is a companion document to the user manual for the beta Streamflow Duration Assessment Methods for the Northeast and Southeast (beta SDAMs NE and SE) of the United States. The beta SDAMs NE and SE are field-based methods for rapidly classifying stream reaches ...

This manual describes beta Streamflow Duration Assessment Methods (SDAMs) that are intended to distinguish flow duration classes (ephemeral, intermittent, and perennial) of stream reaches in the Northeast (NE) region and in the Southeast (SE) region of the United States. All indi...

The Cyanobacteria Assessment Network is an interagency project collaboration between US EPA, NASA, NOAA, and USGS. The project aims to advance the science of detecting and monitoring cyanobacteria blooms in lakes across the US using satellite imagery from the MERIS and Sentinel 3...

The EPA has a long history of using remote sensing imagery, data products, and services. Beginning with the production of Superfund site assessments by Environmental Photographic Interpretation Center in the 1970s to current agencywide use of commercial high resolution satellite ...

Seagrasses have been widely recognized for their ecosystem services, but traditional seagrass monitoring approaches emphasizing ground and aerial observations are costly, time-consuming, and lack standardization across datasets. This study leveraged satellite imagery from Maxar's...

Harmful algal blooms caused by cyanobacteria are a threat to global water resources and human health. Satellite remote sensing has vastly expanded spatial and temporal data on lake cyanobacteria, yet there is still acute need for tools that identify which waterbodies are at-risk ...

The management and governance of our surface waters is core to life and prosperity on our planet. However, monitoring data are not available to many potential users and the disparate nature of water bodies makes consistent monitoring across so many systems difficult. While satell...
