General overview of the Cyanobacteria Assessment Network (www.epa.gov/cyanoproject) current technology, software, and data. A future look of using Sentinel-2 higher resolution imagery and forecasting will also be provided.

With increasing concerns about freshwater cyanobacteria blooms, there is a need to identify which waterbodies are at risk for developing these blooms, especially those that produce cyanotoxins. To address this concern, we developed spatial statistical models using the US National...

CyAN is a multi-agency project to develop an early warning indicator system to detect algal blooms in U.S. freshwater systems. This research supports federal, state, tribal, and local partners in their monitoring efforts to assess water quality to protect aquatic and human health...

Cyanobacterial harmful algal blooms pose environmental, economic, and human health concerns across waters of the United States.  However, monitoring changes in cyanobacteria at broad spatial and temporal scales remains difficult and many times with sporadic coverage. The Cya...

Cyanobacterial harmful algal blooms are a global problem with a need for synoptic monitoring capability.  The project objective is a Sentinel-2 (S-2) chlorophyll demonstration monitoring product for Florida, Ohio, and Oregon. This is an annual project report to the USACE Har...

This overview is designed for a general audience without expertise in satellite remote sensing and forecasting. It is meant to highlight how the Cyanobacteria Assessment Network, CyAN , might provide useful real-time data, software, training, annual summary metrics, and 1-week fo...

Cyanobacterial harmful algal blooms (HABs) can produce toxins that impair freshwater ecosystems used for drinking water, recreation, and habitat for aquatic biota. With HABs increasing in extent and intensity globally, water managers need information about how to prioritize lake ...

Harmful algal blooms (HABs) are an environmental, economic, and public health hazard due to their ability to degrade freshwater ecosystems with fish kills, decrease recreation and tourism, and cause severe illness or death in mammals.  Monitoring practices and understanding ...

This forecasting approach may be useful for water managers and associated public health managers to predict near-term future high-risk cyanobacterial harmful algal blooms (cyanoHAB) occurrence. Freshwater cyanoHABs may grow to excessive concentrations and cause human, animal, and...

In a world with increasing environmental hazards, harms, and challenges, environmentally just outcomes require intentional and inclusive risk communication. Standard risk communication uses a deficit approach, sharing scientific information without intentional consideration of co...

CyAN is a multi-agency project to develop an early warning indicator system to detect algal blooms in U.S. freshwater systems. This research supports federal, state, tribal, and local partners in their monitoring efforts to assess water quality to protect aquatic and human health...

The Geostationary Littoral Imaging and Monitoring Radiometer (GLIMR) will provide unique high temporal frequency observations of the United States coastal waters to quantify processes that vary on short temporal and spatial scales. The frequency and coverage of observations from ...

Detecting and managing HABs is of high importance, with efforts moving forward for both acute management through recreational advisories and long-term management to protect designated uses. While remote sensing technology has enabled quantification of HABs at frequencies and spat...

Loss of water access due to toxin-producing cyanobacteria is a growing concern for the public and water managers across the United States. There is limited field data on cyanobacteria but predicting which waterbodies will be affected is critical for targeting monitoring and ...

Lake Erie is threatened by eutrophication and harmful algal blooms due to excess nutrient loading from agricultural sources. To reduce nutrient loading to Lake Erie, widespread adoption of agricultural conservation practices (ACPs) in contributing watersheds has been proposed. Ho...

CyANWeb is a browser-based interface that has been tested and targeted for desktop/laptop browsers. It is certainly possible to use smaller devices to access the web interface (e.g., smart phones and tablets). This document’s screenshot images show how the CyANWeb interface...

CyAN is a multi-agency project to develop an early warning indicator system to detect algal blooms in U.S. freshwater systems. This research supports federal, state, tribal, and local partners in their monitoring efforts to assess water quality to protect aquatic and human health...

Dissolved reactive phosphorus (DRP) export from agricultural areas is a leading cause of nutrient pollution in freshwater systems (e.g., the North American Great Lakes). A potential solution to mitigate the excessive release of DRP is the use of nutrient management practices. To ...

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...

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...

Despite the abundance of various cyanobacteria efforts that are taking place, the problem still exists that there are not good regional perspectives of when, where, and how many blooms are occurring, how long they are lasting, are they producing toxins, is this a newly occur...

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 ...

This presentation gives an overview and update on EPA ORD’s HABs research since the last USACE Interagency workshop on Freshwater HABs. The legislative drivers related to freshwater HABs are explained. The research discussed provides stakeholders and decision-makers at the ...
