December 2020 Indian River Lagoon Water Quality Update by Chuck Jacoby

December 16, 2020

North Indian and Banana Rivers - In this webinar video, Dr. Chuck Jacoby uses data tables and time lapsed satellite images to present the science behind Brevard County's recent alga blooms.

Dr. Jacoby demonstrates how June's rainfall lowered the lagoon's salinity and enabled the growth of a NEW and UNIDENTIFIED nanocyanobacterium alga. By November, the bacteria decomposing the Blue-Green alga depleted the water's oxygen, and caused over 74 reported fish kills throughout Brevard.

Thankfully, December's lower temperatures and increased wind activity dissipated the decaying cyanobacterium alga and bacteria, and now dissolved oxygen levels are on the rise.

The video is available on the Indian River Lagoon YouTube Channel at https://www.youtube.com/watch?v=RmniQoVnJdQ.

Dr. Jacoby's presentation slides are available at http://publicfiles.dep.state.fl.us/DEAR/BMAP/IndianRiverLagoon/Meetings/Lagoon-wide/2020/2020_12/SJRWMD_slides_BMAP_update_20_12_16.pdf.
