Subsurface Algae Seeds Surface Harmful Algal Blooms in Southern California

Recently published findings from an NCCOS supported study in the central Southern California Bight indicate that harmful algal blooms (HABs) of Pseudo-nitzschia can develop offshore and below the surface prior to appearance near surface coastal waters. Surface blooms during the study period coincided with periods of upwelling or other processes that caused subsurface algal populations to move higher […]

Why Nutrient-Enriched Waters Favor Large Single-Cell Algae

Ecological studies show that bottom-up (e.g., nutrient input) and top-down (e.g., grazing/predation) pressures may change the structure of aquatic ecosystems with “cascading” effects throughout the food chain. Recent research supports that zooplankton grazing in high-nutrient waters promotes the growth of larger phytoplankton over smaller species, creating a higher abundance of these larger single celled algae within the food web. Using samples […]

NOAA and Louisiana Collaborate on Mississippi River Diversion Management

The 5th Annual NOAA/Northern Gulf Institute Gulf Hypoxia Research Coordination Workshop brought together Louisiana state officials, federal and other state agencies, NGOs, and academic scientists with interests in identifying a path forward to restore Louisiana’s coastal wetlands, reduce the size of the annual Gulf of Mexico hypoxic zone, and sustain the ecological and socioeconomic benefits of […]

Sea Level Rise Shoreline Model Reconstructs Past to Predict Future

A unique NCCOS sponsored study, recently published in Contenental Shelf Research, examined the influence of sea level rise (SLR) on historic mainland and barrier island beaches and salt marshes of Mississippi’s Grand Bay in Mississippi Sound. The research used historical data to investigate how excess erosion in Grand Bay and SLR will affect any future changes […]

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 […]

Government Regulators Consider Negative Impacts of Shoreline Armoring

Results from a six-year NCCOS sponsored study on the impacts of different approaches to erosion control – seawalls, riprap, and “living” shorelines – on submerged aquatic plants, crabs, fish, ducks, and geese in Chesapeake Bay has prompted government regulators to consider the cumulative impacts of shoreline armoring projects in upcoming management decisions. Scientists have presented […]

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 […]
