Predicting the Risks of Harmful Algal Blooms for Coastal California

In California, domoic acid-producing harmful algal blooms (HABs) of the diatom Pseudo-nitzschia increasingly threaten bivalve and crab harvesters, aquaculture, and coastal ecosystems. Using a blend of models and satellite ocean color imagery, NCCOS supported the early development of the California Harmful Algae Risk Mapping (C-HARM) system that predicted the spatial likelihood of Pseudo-nitzchia blooms and levels of […]

NOAA Awards $3.4 million to Support Coastal Community Resilience

NOAA’s National Centers for Coastal Ocean Science are awarding over $1.3 million, with an anticipated total of $3.4 million over the next four years, for research that will provide coastal managers with the science to plan for sea level rise and flooding, and improve the resilience of their communities. With increasing threats to our coasts, enhancing resilience to […]

Addressing Offshore Aquaculture in California

On September 27 in Long Beach, California, NOAA, Aquarium of the Pacific, and California Sea Grant, issued a report and held a workshop featuring proposed fish farming operations in Southern California’s offshore waters and current operations in U.S. marine waters. Participants sampled responsibly farmed U.S. seafood and explored live animal exhibits about aquaculture. The report […]

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 […]

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 […]

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 […]

Predicting Ocean Acidification and Hypoxia with West Coast Stakeholders

The California Current System (CCS) is among the most biologically productive regions of the world’s oceans, but upwelling of coastal waters creates vulnerability to ocean acidification and hypoxia (OAH), which scientists observed in recent decades. A project funded through the NOAA Ocean Acidification Program and NCCOS in collaboration with the California Ocean Protection Council is […]

Producing a new Reference Material for Paralytic Shellfish Toxin Monitoring

Saxitoxins, produced by species of harmful algal blooms (HABs), cause paralytic shellfish poisoning (PSP) when contaminated seafood is consumed. For nearly 50 years the U. S. Food and Drug Administration (FDA) has provided a saxitoxin dihydrochloride standard to state shellfish laboratories and others who monitor seafood safety, and has distributed it as a National Institutes of Standards […]
