First Compendium on Deep-water Algae of Puerto Rico Published

A new taxonomic publication describes the relatively unknown algal flora of mesophotic coral ecosystems in Puerto Rico. These ecosystems are characterized by the presence of light-dependent corals and associated communities found at depths ranging from 100 to 500 feet deep. The work, published in a recent issue of Smithsonian Contributions to Botany, was supported partly by the […]

Tiny yet Toxic: Dinoflagellate Karlodinium veneficum

Relatively unknown and taxonomically confusing until the last few decades, the tiny but toxic dinoflagellate, Karlodinium veneficum, can produce dense blooms and fish-killing toxins. K. veneficum is a small chlorophyll-containing dinoflagellate that produces a suite of potent toxic compounds known as karlotoxins which kill fish as well as other organisms. K. veneficum has a mixed nutritional mode […]

Mesophotic Bicolor Damselfish Help Keep Shallower Reef Populations Afloat

NOAA-supported researchers studying the potential coral ecosystem connectivity of the deep (192-256 ft/60-80 m), mesophotic reefs of Pulley Ridge and the shallower reefs downstream in the Florida Keys found that bicolor damselfish populations on shallower reefs may owe some of their sustainability to mesophotic reefs. In comparison to shallower reefs, the bicolor damselfish populations on mesophotic […]

Tour America’s Coastal Aquaculture on MarineCadastre.gov

NOAA’s Office for Coastal Management and National Centers for Coastal Ocean Science have produced the first edition of the national coastal ocean aquaculture geospatial data layer. This project compiles current aquaculture data from 15 coastal states, standardizing aquaculture data into three categories (shellfish lease, finfish lease, and other [crustaceans, algae]). The layer shows the approximate location […]

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 […]
