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 […]

NCCOS a Big Player at 2017 Gulf of Mexico Alliance Meeting

NCCOS scientists and sponsored principal investigators (PIs) joined hundreds of other scientists and managers interested in the ecology and sustainability of the Gulf of Mexico at the Gulf of Mexico Alliance (GOMA) 2017 All Hands Meeting in Houston, Texas, in late March. With research spanning decades, NCCOS supports a robust research portfolio in the Gulf […]

Renewed Interest to Study Ciguatera Risks in Papahanaumokuakea Marine National Monument

Dr. Alison Robertson, an NCCOS ECOHAB†sponsored ciguatera expert with the University of South Alabama and Dauphin Island Sea Lab (USA\DISL), is helping the NOAA Office of National Marine Sanctuaries (ONMS) assess human health threats related to ciguatera fish poisoning in island†waters within the Papahanaumokuakea Marine National Monument (PMNM). Ciguatera is a major, if not the […]

Multiple Marine and Freshwater Algal Toxins Documented in Southern California

NCCOS-sponsored scientists recently documented the occurrence of several, potentially harmful cyanobacteria and associated toxins at the land-sea interface along the southern California coast. Their newly published findings in the journal Toxins reveal a previously unrecognized, potential human health threat from cyanotoxins in our coastal waters, raising new concerns for recreation, harvesting of finfish and shellfish, […]

NOAA-Funded Workshop Addresses State of Harmful Algal Bloom Sensors

In late January 2017, NCCOS scientists Marc Suddleson and Greg Doucette joined U.S. and international colleagues at an Alliance for Coastal Technologies workshop funded by NOAA Integrated Ocean Observing System to evaluate the state of harmful algal bloom (HAB) sensor technologies. Attendees†focused on ways to expedite sensor transition to commercialization and the potential for integrating […]

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 coralís 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 […]
