Puget Sound Water Quality Review Highlights NCCOS HAB Research

The Puget Sound Ecosystem Monitoring Program released the 4th annual report on marine water conditions in Puget Sound for 2014 on September 9, 2015. The report, “Puget Sound Marine Waters: 2014 Overview,” enhances the understanding of the complex ecosystem of Puget Sound, an economic lifeline for Western Washington. The comprehensive report covers a host of […]

NCCOS Sponsors 20 New Research Projects

NCCOS awarded nearly $4.5 million in new research grants while maintaining sponsorship of 42 continuing projects during 2015 for a total of $8.2 million in funding for innovative research. All of the endeavors address significant and complex coastal issues. The projects were selected using a rigorous, competitive, and peer-review process. The cutting-edge research will provide critical […]

Toxic Algae and Their Seaweed Hosts May Predict Ciguatera Fish Poisoning

New research shows that different Caribbean species of Gambierdiscus—the microscopic marine algae most often associated with ciguatera fish poisoning (CFP)—demonstrate different growth and attachment behaviors with different coral reef seaweed hosts. The findings are helping researchers understand how ciguatoxin moves through the food web, information which, in turn, could be used to improve reef sampling and monitoring […]

New Technology Documents Rapid Phytoplankton Response to Tropical Storms and Hurricanes

A scientific study funded by NCCOS’ ECOHAB program, shows phytoplankton community structure changing rapidly, often by the hour, as tropical cyclones pass by. A revolutionary sampling instrument, the Imaging FlowCytobot (IFCB) allows hourly real-time continuous observation of phytoplankton changes. Over time the IFCB provides an extraordinary view of phytoplankton community structure. Prior studies of phytoplankton responses to […]

Origin of Toxic Red Tides in Texas Identified

New modelling research sponsored by NCCOS shows that Texas red tides originate in the southwestern Gulf of Mexico in the Bay of Campeche. These harmful algal blooms, caused by the dinoflagellate alga Karenia brevis, result in large fish kills, human respiratory irritation, and shellfishing closures in affected areas. Unlike red tides on the west coast […]

NCCOS Prepares Toxin Sensor for Deployment in Puget Sound, WA

NCCOS scientist, Tina Mikulski, completed critical calibration of the domoic acid (DA) toxin sensor on an Environmental Sample Processor (ESP) platform located at NOAA’s Northwest Fisheries Science Center (NWFSC) in Seattle, Washington. This ESP (referred to as ‘ESPfriday’) will be deployed for the first time in Puget Sound beginning in early August and will generate autonomous, […]

Assessing the Florida Keys National Marine Sanctuary: Blog Post

by Jen Maucher Fuquay During the past week I’ve  been a part of the Ecosystem Assessment Survey cruise through the Florida Keys National Marine Sanctuary (FKNMS) aboard the NOAA ship Nancy Foster.  Everyone has been working hard around the clock (literally!) collecting various sample types that will be analyzed as indicators of the health of […]

NCCOS and NMFS Partner to Survey “Unprecedented” West Coast Toxic Algal Bloom

NOAA Fisheries announced it has mobilized extra scientists to join a fisheries survey aboard the NOAA Ship Bell M. Shimada charting an extensive harmful algal bloom (HAB) that spans much of the West Coast. An NCCOS sponsored Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) project in southern and central California comparing coastal HAB ‘hot spots’ analyzes water samples […]
