Summary

This data release provides phytoplankton identification, phytoplankton enumeration, chlorophyll concentration, phaeophytin concentration, phycocyanin data, and nutrient quality assurance data from three recurring algal bloom sites in Kabetogama Lake, Voyaguers National Park, Minnesota in 2016 and 2017. The goal of this research is to better understand the drivers of algal bloom toxicity in the large lakes of Voyageurs National Park so that resource managers may better predict, manage, and mitigate the occurrence of harmful algal blooms. A total of 126 environmental samples were collected at three recreational areas where blooms frequently occur. One site, Sullivan Bay, was chosen for more intensive sampling, including the algal enumeration [...]

Purpose

The overall purpose of the proposed research is to better understand the drivers of bloom toxicity, including environmental and water-quality factors, and changes throughout the open water season in cyanobacterial community structure (in terms of abundance, species composition, and toxin production capability) so that resource managers may better predict, manage, and mitigate the occurrence of cyanobacterial harmful algal blooms. In support of the overall purpose of the project, it is important to understand how the community structure of the bloom changes as toxin production begins. The phytoplankton community in the cyanobacterial blooms of Kabetogama Lake has included significant biovolumes of Microcystis and Anabaena (Christensen and others, 2011), known toxin producing genera.
