NCCOS and Partners Conduct Ecological Assessment in NOAA’s Choptank Habitat Focus Area

NCCOS led a six month-long ecological assessment (EA) this year in the Tred Avon River, the largest tributary of the Choptank River in Chesapeake Bay. The Choptank River Complex is one of ten U.S. Habitat Focus Areas designated by NOAA for the purpose of concentrating agency investments and expertise at the landscape scale to improve […]

NOAA and Partners Address Environmental Concerns of Great Lakes Commercial Net-Pen Aquaculture

A Blue Ribbon Panel of scientists from NOAA, state, and academia recently released a report addressing environmental concerns with development of a net-pen aquaculture industry in the Great Lakes.  The report, Great Lakes Net-Pen Commercial Aquaculture: A Short Summary of the Science, details many issues including the need for best management practices for operations and […]

‘Smartphone Microscopes’ Help Provide Early Warning of Harmful Algal Blooms in Lake Erie

Citizen scientists are using “smartphone microscopes” to identify harmful algal blooms in Lake Erie. The NCCOS Phytoplankton Monitoring Network, in collaboration with the U.S. Environmental Protection Agency, supplied volunteers in Western Lake Erie with the new generation of “smart” microscopes, which have built-in tablets. Each smartphone tablet is pre-loaded by NCCOS scientists with “Phyto”—an application that […]

NCCOS Research Shared with Public at South Carolina Outreach Event

Last month, NCCOS scientists staffed an exhibit at a weekend open house for the public held by the South Carolina Department of Natural Resources (SCDNR). The team conveyed the value of current research at the NCCOS Center for Coastal Environmental Health and Biomolecular Research and the Hollings Marine Laboratory that focuses on the effects of natural and […]

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 […]

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 […]

NOAA Joins International Coastal Cleanup, Removes 157 Pounds of Debris in North Carolina

As part of the Ocean Conservancy’s International Coastal Cleanup last month, 18 participants from NOAA, North Carolina Coastal Reserve and National Estuarine Research Reserve, and Duke University Marine Laboratory removed 157 pounds of marine debris from the coastal marshes that surround Pivers Island in Beaufort, NC. Debris was cataloged according to the Ocean Conservancy guidelines and all […]

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 […]
