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.
]In this article, we share the development of the Lake Champlain cyanobacteria monitoring program and the current design. Its citizen-supported sustainable approach is now applied statewide in Vermont and may be a useful example for others looking to develop a cyanobacteria monitoring program.
The process of assessing the potential danger of cyanobacteria in a water body includes several steps. Step 3 focuses on the identification of cyanobacteria present in the sample.
The process of assessing the potential danger of cyanobacteria in a water body includes several steps. Step 1 focuses on how to sample a bloom in the field and preserve samples for analysis.
The process of assessing the potential danger of cyanobacteria in a water body includes several steps. This step focuses on how to detect a bloom.
With a special focus on Lake Erie, this Harmful Algal Blooms video covers the basics of HABs, including the causes, potential dangers, and sampling approaches.
The HABs Collaboratory follows the “Collective Impact” model, where individuals from a variety of different groups come together to solve a specific problem and are supported by a neutral backbone organization. The HABs Collaboratory provides a unique opportunity for researchers to interact with other researchers from a variety of disciplines and institutions and to facilitate the use of scientific information to support relevant decisions by managers and practitioners.
The Cyanobacteria Monitoring Collaborative monitoring activities are carried out under three different program “tiers” that represent different monitoring objectives and complexity. Regardless of the level of expertise involved, all three programs (bloomWatch, cyanoScope, and cyanoMonitoring), in addition to professional monitoring entities, leverage the collection of data by crowdsourcing and citizen science.
Unfortunately, for many lakes, long-term monitoring information on bloom history, productivity and nutrient levels, water column temperature, and other factors that may contribute to algal bloom formation often only exist for the last few years, if at all. Paleolimnology offers valuable insights into past environmental conditions to improve our understanding of current lake management issues.
Increased frequency and severity of cyanobacterial blooms suggests that toxins are a threat that must be taken seriously. However, not all cyanobacteria are toxic – so how can we know which blooms pose a health risk? We developed both now- casting and forecasting approaches based on a nine-year data set of microcystin concentrations collected biweekly from Buffalo Pound during summer months
