2019 Summer LakeLine issue on Harmful Algal Blooms

2019 Summer LakeLine issue on Harmful Algal Blooms
Every other year, the summer issue of NALMS LakeLine focuses on what is currently going on in terms of cyanobacteria research, technologies, and advisories. It seems like HABs are occurring at an ever-increasing frequency, with Lake Erie’s large and long-lived bloom well-publicized in the media in recent years, and fears lingering of another such epic bloom. Topics in the 2019 summer issue include the detection of cyanobacteria with satellites, a well-developed monitoring program on Lake Champlain, and the importance of studying benthic cyanobacteria.

Visualizing Cyanobacteria from Space

Visualizing Cyanobacteria from Space | NALMS LakeLine Summer 2019
California has funded the San Francisco Estuary Institute to develop an interactive Satellite Analysis Tool to characterize the seasonality, spatial distribution, and development of harmful algal blooms in 250 of the state’s largest waterbodies. This tool provides a spatial display of cyanobacteria blooms, easy to understand charts that let you see long-term and short-term trends.

Satellite-Detected Cyanobacteria in Large U.S. Lakes on Your Android Phone

Satellite-Detected Cyanobacteria in Large U.S. Lakes on Your Android Phone | NALMS LakeLine Summer 2019
Water quality managers need access to current, inexpensive and quality data to protect water resources. To assist in the proactive management of cyanoHAB events, EPA researchers, along with researchers from NASA, NOAA, and the USGS have developed a time-efficient way to use satellite data in monitoring for cyanoHAB events to help protect recreational and drinking water sources.

A Deeper Look at HABs

A Deeper Look at HABs | NALMS LakeLine Summer 2019
Cyanobacteria that have the potential to cause HABs can be found in a diverse array of aquatic systems, from the highly visible planktonic blooms to less conspicuous benthic mats. To date, benthic cyanobacteria that grow on substrates in aquatic ecosystems have been overlooked in risk assessments.
