Study Shows Harmful Algal Bloom Species Has Distinct Bacterial Flora

A new study supported in part by the NCCOS Monitoring and Event Response for Harmful Algal Blooms (MERHAB) finds the harmful algal bloom (HAB)-forming diatom Pseudo-nitschia (PN) maintains a distinct bacterial community living on and near its exterior cell wall. The findings offer new insights into possibly using bacteria as indicators of HAB species composition, control […]

Extensive Hawaiian Reefs in Oceanic “Twilight Zone” Harbor Many Unique Species

NOAA-supported scientists working in the Hawaiian Archipelago documented some of the most expansive mesophotic reefs (deeper light-dependent reefs between 100-500 feet depths) in what some refer to as the oceanic “twilight zone.” The exploration revealed several large areas of 100-percent coral cover, particularly in Maui’s ʻAu‘au Channel. Of the fish species observed, 43 percent were unique to […]

NOAA Funds Harmful Algal Bloom Forecast System Development in Pacific Northwest

NOAA’s National Centers for Coastal Ocean Science (NCCOS) are funding development of a harmful algal bloom (HAB) forecast in the Pacific Northwest to support management of shellfisheries, clamming beaches, and human health. The experimental monitoring and forecasting system will launch in 2017, with forecast bulletins predicting bloom location and concentration several days in advance. Annual […]

NCCOS Personnel Receive Emergency Response Training

NCCOS scientists participated in the first NOAA “300 level” course titled: “Intermediate Incident Command System Training” last month in Silver Spring, MD in preparation for agency-wide response to natural or man-made emergency incidents or to deploy to an emergency or disaster center. The Incident Command System (ICS) was developed to respond to emergencies using standard job roles, forms, and […]

NOAA Provides Harmful Algae Identification Training

Effective monitoring and management of harmful algal blooms (HABs) relies on accurate and timely identification of the species involved. Phytoplankton responsible for HABs varies dramatically in size, shape, pigmentation, toxins, habitat, life history, and ecology. Until recently only Europe offered comprehensive HAB identification training, but NCCOS now provides taxonomic training for a new generation of […]

Sensitivity of California Current Species to Ocean Acidification

A new study estimated the sensitivity of different groups of marine species to ocean acidification (OA) within the California Current ecosystem. Species groups were designated based on having similar functions in the ecosystem (i.e. urchins, oysters, phytoplankton, zooplankton), and the OA sensitivity for each group was determined based on previous studies. Most functional groups of species (26 of 34) responded negatively to […]

Predicting Red Tides in the Eastern Gulf of Mexico

NCCOS sponsored researchers with the University of South Florida and the Florida Fish and Wildlife Conservation Commission identified why red tide blooms of toxic Karenia brevis off the west coast of Florida are worse in some years than others, and predict there will be no major red tide outbreaks along Florida’s west coast in 2016. […]

Outlook for Impact of HABs on 2016 Crab Season in California

On August 11, 2016  Dr. Raphael Kudela, with the University of California Santa Cruz, testified on “Harmful Algal Blooms and Domoic Acid: Latest Forecast and a Look Ahead to the Upcoming Season” to the Joint Committee on Fisheries and Aquaculture of the California Legislature. Kudela discussed the massive west coast-wide 2015 toxic Pseudo-nitzchia bloom, drawing a strong link between […]
