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, […]

Hardened Shorelines Decrease Small Fish and Invertebrate Abundance

New NCCOS-sponsored research shows that shoreline hardening has mostly negative effects on estuarine animals. This is evident both at a local scale directly next to a hardened shoreline and at the larger system-wide scale as the percent of shoreline hardening accumulated in an estuarine area. Scientists examined 15 common fish and invertebrate species in tributaries of […]

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 […]

Hypoxia Effects on Fish and Fisheries in the Gulf of Mexico

Dr. Kim de Mutsert, lead Principal Investigator (PI) for the newly awarded Northern Gulf of Mexico project “User-driven tools to predict and assess effects of reduced nutrients an hypoxia on living resources in the Gulf of Mexico,” led a workshop entitled “Hypoxia effects on fish and fisheries” at the Gulf of Mexico Oil Spill and […]

Online Tool Explores Sea Level Rise and Coastal Marsh Health Scenarios

A new online tool developed by the University of South Carolina, with funding through NCCOS’s Ecological Effects of Sea Level Rise program (EESLR), allows users to evaluate scenarios of coastal saltmarsh health under a suite of sea level rise conditions. In addition to visualizing results through the web interface, users can download the results to […]

Gulf of Mexico Sea Level Rise Tools Delivered to Coastal Managers

NCCOS staff and their partners held a workshop last month in Alabama to demonstrate and transfer sea level rise tools and data to regional coastal managers. Hosted by the Weeks Bay National Estuarine Research Reserve (NERR), over 40 representatives from federal, state, and local agencies and non-governmental organizations engaged in training sessions and hands-on activities […]

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, […]
