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 […]

Shellfish Larvae Struggle in Fluctuating Oxygen and Acidity in Estuaries

A study supported by NCCOS and the NOAA Ocean Acidification Program found that interacting effects of acidified and low oxygen (hypoxic) waters reduced the survival, growth, and development of larval stages of three important shellfish species: bay scallops, hard clams and eastern oysters. Shellfish larvae were exposed to ideal, acidified and low oxygen conditions both individually and in […]

NCCOS Helps New England Respond to Unprecedented Harmful Algal Bloom

For the first time in New England’s coastal waters, shellfish have exceeded the regulatory limit for domoic acid—a potent neurotoxin produced by the diatom Pseudo-nitzschia. Domoic acid accumulates in shellfish that feed on Pseudo-nitzschia, and can lead to amnesic shellfish poisoning in people who consume tainted shellfish. The NCCOS Harmful Algal Bloom Event Response Program […]

Keeping Up With Rising Seas

Scientists predicted wetland soil accretion (or growth) rates in relation to predicted sea level rise using a model and data from numerous tidal salt and freshwater wetlands around the United States. The model results, published in Earth’s Future, suggested that, on average, softer organic components of East Coast marsh sediments do not accrete  fast enough in volume and height […]

2015 Harmful Algae Cyst Cruise: Student Blog

By Eric Gulledge, Ph.D. candidate at Jackson State University I am a NOAA-Environmental Cooperative Science Center fellow and currently enrolled in the Environmental Science Ph.D. program at Jackson State University. The NOAA-ECSC strives to train and develop student’s skills related to interdisciplinary science in support of coastal management. In keeping with NOAA’s mission, NOAA-ECSC afforded […]

The Future of Algae Bloom Monitoring Technology

Technology developed with NCCOS funding is rapidly advancing harmful algal bloom (HAB) monitoring capabilities nationwide. These cutting edge detection tools are now commercially available and transitioning them to sustained management operations is the new norm. Recently a U. S. National Park Service (NPS) funded study benefited from the use of the NCCOS-developed “underwater microscope” Imaging […]

Model Allows Scallop Industry to Plan for Impacts of Climate Change

NCCOS-sponsored researchers have developed a user-friendly computer program to help manage the U.S. commercial Atlantic sea scallop fishery, which is threatened by progressively higher temperatures and ocean acidification. The Integrated Assessment Model (IAM) concurrently simulates ocean conditions related to temperature and ocean acidification, sea scallop population dynamics, and economic impacts on the scallop fishery. In the […]
