Mesophotic Reefs in Southwest Puerto Rico Shaped by Sediment Movement

Sediment exerts a basic control on the character and distribution of both shallow and mesophotic coral ecosystems (MCEs). In a rare study focused on sediment dynamics of MCEs, NCCOS-supported scientists found that downslope bed-load transport from shallower reefs (by coral and calcareous algae) exceeds suspended-sediment accumulation and has important influence in shaping MCEs in southwest […]

Southeast Deep Coral Initiative: NOAA Multi-Year Effort to Study Deep-Sea Corals

A new NOAA report outlines the objectives and activities of the Southeast Deep Coral Initiative (SEDCI). The initiative is a coordinated, cross-line office effort that includes partners from NOAA Fisheries, Ocean and Atmospheric Research, and National Ocean Service; and aims to collect scientific information needed to manage deep-sea coral ecosystems across the Southeast U.S through […]

Depth Affects Algal Symbiont Composition in Caribbean Coral

NCCOS-funded researchers investigating the diversity of symbiotic algae (Symbiodinium spp.) associated with the coral Agaricia lamarcki in Puerto Rico and the U.S. Virgin Islands found the coral’s algal associations change with depth. Light-dependent corals form a mutually beneficial relationship (symbiosis) with the single-celled algae Symbiodinium, commonly known as zooxanthellae, which provide energy for the coral […]

Reducing Migratory Duck Mortality on Padre Island, TX

An extremely toxic Microcystis bloom on a pond in the Padre Island National Seashore was associated with a significant mortality of redhead ducks (Aythya americana). The primary concern is the mortality of redhead ducks that use this region as a major wintering ground. The NCCOS Event Response Program has funded a researcher from Texas A&M University […]

Protected Species Assessment Addresses Interactions with Marine Aquaculture

New research from NOAA’s National Centers for Coastal Ocean Science (NCCOS) assesses the impacts that aquaculture gear and infrastructure may have on protected species. Aquaculture already supplies more than half of the world’s seafood, and this contribution will likely rise dramatically over the next few decades. As coastal aquaculture expands, so does the potential for interactions […]

2017 California Estuary Harmful Algal Bloom Monitoring Begins

Last month, NCCOS-sponsored scientists began harmful algae and algal toxin monitoring in California estuaries. The monitoring is part of a collaborative NOAA–state response to recent research showing that a mixture of marine and freshwater toxins can reside in estuarine waters. The research found that this toxic “cocktail” could also be fatal to shellfish, sea otters, […]

Successful First Year of NOAA’s Deep-Sea Coral Initiative in the Southeast

In 2016, NOAA’s Deep-Sea Coral Research and Technology Program started a new four-year initiative to study deep-sea coral and sponge ecosystems across the southeastern U.S., a region including U.S. federal waters in the South Atlantic, Caribbean Sea and the Gulf of Mexico. The initiative is led by the NCCOS Deep Coral team, and is a […]

Experts Shape the Future of Caribbean Coral Restoration Science and Practice

Adapted text from Tali Vardi Coral restoration scientists, practitioners, and resource managers gathered at the Workshop to Advance the Science and Practice of Caribbean Coral Restoration in Fort Lauderdale, FL last month to address the rapidly expanding and evolving role of active coral restoration in the management of coral reef ecosystems. The three-day meeting facilitated […]
