Less than 50% of the Channel Islands National Marine Sanctuary seafloor has been mapped using multibeam echosounders to produce habitat characterizations at a map resolution suitable for resource management. This is important because deep-sea coral and sponge communities are known to occur within the Sanctuary. Mapping activities and benthic survey ...

This cruise report is a summary of a field survey conducted along the continental shelf of the northeastern Gulf of Mexico (GOM), encompassing 70,062 square kilometers of productive marine habitats located between the Mississippi Delta and Tampa Bay, August 13 – 21, 2010 on NOAA Ship Nancy Foster Cruise NF-10-09-RACOW ...

The overall purpose of the survey was to collect data to assess the status of ecosystem condition and potential stressor impacts throughout the region, based on these various indicators and corresponding management thresholds, and to provide this information as a baseline for determining how such conditions may be changing with ...

This cruise report is a summary of a field survey conducted in coastal-ocean waters of the Mid-Atlantic Bight from Nags Head, North Carolina to Cape Cod, Massachusetts and from approximately 1 nautical mile (nm) of shore seaward to the shelf break (100 m). The survey was conducted May 12 - ...

This cruise report is a summary of a field survey conducted in coastal-ocean waters off Florida from Anclote Key to West Palm Beach and from approximately 1 nautical mile (nm) offshore seaward to the shelf break (100 m). The survey was conducted May 15-May 28, 2007 on NOAA Ship NANCY ...

This cruise report is a summary of a field survey conducted within the Stellwagen Bank National Marine Sanctuary (SBNMS), located between Cape Cod and Cape Ann at the mouth of Massachusetts Bay. The survey was conducted June 14 - June 21, 2008 on NOAA Ship Nancy Foster Cruise NF-08-09-CCEHBR. Multiple ...

This cruise report is a summary of a field survey conducted within the Sapelo Island National Estuarine Research Reserve (SINERR), located on the Georgia coastline, June 7 - June 13, 2009. Multiple indicators of ecological condition and human dimensions were sampled synoptically at each of 30 stations throughout SINERR using ...

Cyanobacterial Harmful Algal Blooms (CyanoHABs) are an ongoing threat to water quality, ecosystems, economies, and public health in the Great Lakes region, especially in Lake Erie, Sandusky Bay, Saginaw Bay in Lake Huron, Green Bay in Lake Michigan, and Lake Winnebago. Long-term time series data are required to characterize bloom ...

The shedding sequence of the Loop Current (LC) inside the Gulf of Mexico (GoM) is strongly influenced by cyclonic frontal eddies around its edge. Along-track altimetry data, analyzed based on a wavelet decomposition to provide estimates of individual cyclones’ diameter, amplitude and relative vorticity, and in situ surface drifter data ...

The Deep Coral & Associated Species Taxonomy & Ecology (DeepCAST) II Expedition explored depths below the Meso-American Reef in Roatán, Honduras from 21- 28 May 2011. The team made six submersible dives between 1200 and 2200 feet deep (365 and 670 meters), conducting photo and video transects to estimate coral ...

Over the past several decades, the input of anthropogenic litter into the marine system has been an increasing global concern, with negative ecological and environmental consequences. Plastics, abandoned fishing gear and other debris can have serious effects on marine animals, via entanglement and ingestion. Wildlife stranding and response networks have ...

Over the past 4 decades, Hawaii has developed a system of Marine Life Conservation Districts (MLCDs) to conserve and replenish marine resources. These MLCDs vary in size, habitat quality, and management regimes, providing an excellent opportunity to test hypotheses concerning marine protected area (MPA) design and function using multiple discreet ...

As humans expand into natural environments, populations of wild organisms may become relegated to marginal habitats at the boundaries of their distributions. In the ocean, mesophotic coral ecosystems (30–150 m) at the depth limit of photosynthetic reefs are hypothesized to act as refuges that are buffered from anthropogenic and natural disturbances, ...

Corals at the lower limits of mesophotic habitats are likely to have unique photosynthetic adaptations that allow them to persist and dominate in these extreme low light ecosystems. We examined the host–symbiont relationships from the dominant coral genus Leptoseris in mesophotic environments from Hawai'i collected by submersibles across a depth ...

Zooplankton grazing is often a significant loss term for phytoplankton populations, including harmful algae, impacting the development and decline of blooms. However, detecting and quantifying predation on phytoplankton is often challenging, particularly during early bloom stages when phytoplankton cell concentrations are low. In this study, we used polymerase chain reaction ...
