Gulf of Mexico Offshore Dead Zone Linked to Mississippi River Nutrient Inputs

Twenty-five years of NCCOS sponsored research shows that the offshore summer hypoxic (low-oxygen) “dead zone” in the Gulf of Mexico is strongly linked to nutrient loading from the Mississippi River. Physical forces (i.e., wind, waves, currents, temperature) play an equally strong role as biological variables (i.e., phytoplankton growth/decay, photosynthesis/respiration) in creating and maintaining Louisiana shelf hypoxia […]

Puget Sound Harmful Algal Blooms Linked to Seasonal Patterns and Survival Probability

In order to predict blooms and prevent undue economic loss of commercial shellfish in Puget Sound, NCCOS has sponsored research investigating the seasonal patterns and mechanisms of bloom formation of Alexandrium, a dinoflagellate that contaminates shellfish and causes paralytic shellfish poisoning (PSP) in humans. The study shows Alexandrium survives and spreads in Puget Sound in response to […]

NOAA Shepherds Transition of Gulf of Maine Harmful Algal Bloom Model to Operational Forecast System

NOAA and partners are working to transition a harmful algal bloom (HAB) model for Alexandrium  fundyense in the Gulf of Maine (GoM) into a NOAA operational forecast system (OFS), which would help minimize economic losses to a $200-300 million dollar a year shellfish industry in Maine, New Hampshire, and Massachusetts. A. fundyense is a dinoflagellate phytoplankton that produces […]

Phytoplankton Monitoring Network Highlighted during National Volunteer Week

Public participation in scientific research is a growing trend. Citizen science, as it is called, typically involves data collection by members of the public who pass their information along to researchers trying to answer real-world questions. In support of National Volunteer Week (April 12–18), the National Ocean Service ran a social media campaign this week highlighting […]

NOAA, Partners Will Use Satellites to Protect Public from Harmful Freshwater Algal Blooms

NOAA has partnered with NASA, the U.S. Environmental Protection Agency, and the U.S. Geological Survey to transform satellite data designed to probe ocean biology into information that will help protect the American public from harmful freshwater algal blooms. Harmful algal blooms are a worldwide environmental problem, costing millions of dollars annually. These toxic events threaten […]

NOAA Hosts Harmful Algal Bloom and Hypoxia Research Webinars

NOAA is hosting a series of regional webinars designed to initiate conversation between federal representatives and stakeholders on a number of topics related to harmful algal blooms (HABs) and hypoxia starting this Thursday, at 12:30 pm EDT. The meetings will be led by the Interagency Working Group on the Harmful Algal Bloom and Hypoxia Research and Control […]

The Craib Corer: Predicting Harmful Algal Blooms by Sampling the Seafloor

Forecasting harmful algal blooms is a complex endeavor involving a wide range of oceanographic disciplines. NCCOS scientists and sponsored researchers count the number of harmful algal bloom (HAB) resting stages or cysts that lie on the bottom of the ocean as one method to estimate the future occurrence of HABs. Scientists use a suite of […]

Hypoxia Special Session Lead by NCCOS at 2015 Aquatic Sciences Meeting

Leading a special session on advances in hypoxia modelling, scientists from NCCOS contributed to the global mission of the 2015 Aquatic Sciences (ASLO) Meeting in Grenada, Spain which focused on global and regional patterns of aquatic systems. The hypoxia special session highlighted diverse modeling approaches to a variety of issues from the development of hypoxia […]
