HAB Study Confirms Alexandrium in Alaska, Develops Global Test Method

In an effort to provide forecasting and detection products that empower communities to take action on HAB issues, a new publication in Phycologia documents the presence of Alexandrium fundyense and A. ostenfeldii in Alaska and describes the development of quantitative PCR (qPCR) assays for these species.  This is the first large-scale confirmation of Alexandrium species in Alaska, which are responsible for causing paralytic […]

NOAA-Funded Workshop Addresses State of Harmful Algal Bloom Sensors

In late January 2017, NCCOS scientists Marc Suddleson and Greg Doucette joined U.S. and international colleagues at an Alliance for Coastal Technologies workshop funded by NOAA Integrated Ocean Observing System to evaluate the state of harmful algal bloom (HAB) sensor technologies. Attendees focused on ways to expedite sensor transition to commercialization and the potential for integrating […]

NCCOS Research on Display at 2017 Aquatic Sciences Meeting

From February 26 to March 3, 2017 the Association for the Sciences of Limnology and Oceanography (ASLO) held its biennial Aquatic Sciences Meeting in Honolulu, Hawai′i. NCCOS scientists and sponsored investigators shared their research results with thousands of limnologists and oceanographers from around the world. Topics included harmful algal blooms, hypoxia, science to management applications, […]

Risk of Toxic Shellfish on West Coast Increases with Water Temperature

High levels of domoic acid, a shellfish toxin, are correlated with warmer ocean temperatures offshore of Oregon and Washington. An NCCOS-supported research team led by scientists from Oregon State University, the University of Oregon, and the Oregon Department of Fish and Wildlife found an association between domoic acid levels in shellfish and climate-scale warm ocean […]

Harmful Algal Cyst Sampling Lays Groundwork for 2017 Gulf of Maine Forecast

Scientists from NOAA and Woods Hole Oceanographic Institution (WHOI) recently completed their annual harmful algal cyst sampling in the Gulf of Maine, a critical step for forecasting next year’s harmful algal blooms (HABs) of the toxic Alexandrium fundyense, commonly known as New England red tide. A. fundyense has both a vegetative stage, where cells grow and float in surface […]

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 […]

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 […]

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 […]
