Some Coastal Fish May be Able to Adapt to an Acidifying Environment

A new study shows that some coastal fish may be able to condition their offspring to tolerate seasonally acidifying environments, a result never shown before in wild fish populations. Researchers funded by NCCOS and NOAA’s Ocean Acidification Program sampled a wild, spawning population of Atlantic silversides, then combined this information with carbon dioxide exposure experiments […]

Ocean Acidification: NCCOS-funded Research Reveals Legacy Effect of Early Larval CO2 Exposure on Bivalve Survival and Growth

While, the negative impacts of increasing ocean acidification on clams, scallops and other bivalves the biological basis is still unclear, “legacy effect” of early CO2 explosure can play a significant role in bivalve population dynamics. NCCOS-funded researchers performed a series of experiments to look at the days-to-months impacts of carbon dioxide (CO2) on the larvae of northern quahogs […]

Fish-Killing Algae Species Evades Predators to Survive and Bloom

A recently published study into how Heterosigma rapidly forms blooms discovered a remarkable behavior: they flee. This fish-killing species of microscopic plant swims away when it senses single-celled predators are feeding on others nearby. In response, they take “shelter” in low salinity water layers which the predators find intolerable. The investigators said they had never seen a plant swim […]

NOAA Ocean Acidification Program Finds Supportive Partner in NCCOS

NCCOS-funded scientists working under the auspices of the NOAA Ocean Acidification (OA) Program were recently introduced to the internal research community at a special roll-out and open discussion at the Third International Symposium on the Ocean in a High-CO2 World. Three U.S. ocean acidification researchers were recently awarded NOAA Ocean Acidification Program extramural funding. The […]

Research Promotes Method to Slow the Spread of Encrusting Invasive Species

Dredging channels and cleaning boat hulls or fishing gear in or near established Didemnum colonies can create fragments of these invasive organisms that survive in the water column up to four weeks, disperse long distances, and even reproduce before resettling, possibly in new areas, according to NOAA research. The article suggests that cleaning equipment on land and reducing bottom disturbance […]

New Research Aims to Unravel How Nutrients Drive Toxic “Brown Tides”

NOAA has awarded Massachusetts-based Woods Hole Oceanographic Institution $120,000 as part of an anticipated three-year, nearly $500,000 project, to determine how nitrogen and phosphorus promote brown tides on the East Coast. Funds were awarded through the interagency Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, represented at NOAA by the National Centers for Coastal […]

Invasive Sea Squirts Threaten Shellfish Aquaculture

National Centers for Coastal Ocean Science researchers and their collaborators found that ten invasive tunicate species are fouling shellfish aquaculture operations along much of the U.S. East Coast, causing decreased growth rates, increased mortality, and high maintenance costs.  The survey identified the locations of highest fouling, which will be used to develop a plan to […]
