NCCOS Research on Display at 2017 Aquatic Sciences Meeting

From February 26 to March 3, 2017 the Association for the Sciences of Limnology and Oceanography (ASLO) held its biennial Aquatic Sciences Meeting in Honolulu, Hawai′i. NCCOS scientists and sponsored investigators shared their research results with thousands of limnologists and oceanographers from around the world. Topics included harmful algal blooms, hypoxia, science to management applications, […]

Winners and Losers in the California Current under Future Ocean Acidification

A NOAA-supported study projects that Dungeness crab and some commercial finfish species living on the sea floor may decline in future years due to increased ocean acidification in the California Current. These estimates were based on computer models forecasting changes in the California Current ocean ecosystem, which includes an expected rise in summer ocean acidification […]

Shellfish Larvae Struggle in Fluctuating Oxygen and Acidity in Estuaries

A study supported by NCCOS and the NOAA Ocean Acidification Program found that interacting effects of acidified and low oxygen (hypoxic) waters reduced the survival, growth, and development of larval stages of three important shellfish species: bay scallops, hard clams and eastern oysters. Shellfish larvae were exposed to ideal, acidified and low oxygen conditions both individually and in […]

Sensitivity of California Current Species to Ocean Acidification

A new study estimated the sensitivity of different groups of marine species to ocean acidification (OA) within the California Current ecosystem. Species groups were designated based on having similar functions in the ecosystem (i.e. urchins, oysters, phytoplankton, zooplankton), and the OA sensitivity for each group was determined based on previous studies. Most functional groups of species (26 of 34) responded negatively to […]

NCCOS Briefs Environmental Legislators on Harmful Algal Blooms

Earlier this month, Dr. Quay Dortch (manager of the NCCOS Ecology and Oceanography of Harmful Algal Blooms Program) addressed the Oceans and Coast sub-group of the National Caucus of Environmental Legislators (NCEL). At the Chicago meeting of the sub-group, Dortch described the causes and impacts of harmful algal blooms, federal and state responses, and recommended incorporating […]

NOAA Student Scholars Present Summer Research With NCCOS

Ten student undergraduate scholars, most with the NOAA Educational Partnership Program and Hollings Scholarship Program, are interning this summer with the National Centers for Coastal Ocean Science (NCCOS) in Silver Spring, MD, Oxford, MD, Beaufort, NC, and Charleston, SC. Their internship programs culminated with presentations by each scholar of their summer research at the Science and […]

Meeting Challenges in Estuarine and Coastal Ecosystem Science

Along with individual stressor-based research projects, NCCOS undertakes a broader ecosystem approach using larger, multidisciplinary research projects. A recent essay authored in part by NCCOS sponsored scientists gives perspectives on challenges and paths for advancing estuarine science; NCCOS research strives to meet these challenges. Five major research challenges were identified: (1) Maintaining and improving spatially distributed time-series datasets; […]

NCCOS Science Leads to International Coral Conservation Effort

A group of prominent marine environmental experts recently committed to working with government leaders of Palau, Micronesia, and the Marshall Islands on coral conservation. The group pledged to provide their expertise in natural and social science, engineering, economics, and law to provide scientific and technical assistance to managers and policy makers. This will, in turn, build […]
