Record-setting Razor Clam Harvest Aided by Pacific...

Recreational razor clam harvesters in Long Beach, Washington, set a record for one-day digger trips (17,800 diggers) on April 30, 2017. The record number of trips was triggered by the ...

Second 'Cytobot' Deployed in Texas Harmful Algae E...

NCCOS-funded investigators from Texas A&M University (TAMU) successfully deployed an Imaging Flow Cytobot (IFCB) on a pier near Freeport, Texas. This is the second cytobot deployed in the Gulf of ...

NCCOS a Big Player at 2017 Gulf of Mexico Alliance...

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 ...

Southeast Deep Coral Initiative: NOAA Multi-Year E...

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, ...

A Primer to Living Shorelines Published

A synthesis of recent thinking and results from practitioners and researchers of Living Shorelines just hit the stands. " Living Shorelines: The Science and Management of Nature-Based Coastal Protection," details ...

Reducing Migratory Duck Mortality on Padre Island,...

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 ...

Successful First Year of NOAA's Deep-Sea Coral Ini...

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 ...

Multivariable statistical regression models of the areal extent of hypoxia over the Texas-Louisiana continental shelf

Observations of the areal extent of seasonal hypoxia over the Texas–Louisiana continental shelf from 1985 to 2010 are correlated with a variety of physical and biogeochemical forcing mechanisms. Significant correlation is found between hypoxic area and both nitrogen load (r2 ...

N and P as ultimate and proximate limiting nutrients in the northern Gulf of Mexico: Implications for hypoxia reduction strategies

The occurrence of hypoxia in coastal oceans is a long-standing and growing problem worldwide and is clearly linked to anthropogenic nutrient inputs. While the need for reducing anthropogenic nutrient loads is generally accepted, it is costly and thus requires scientifically ...

National Centers for Coastal Ocean Science (NCCOS) long-term monitoring: Regional Ecological Assessments and National Benthic Inventory (NCEI Accession 0202842)

The NCCOS Regional Ecological Assessments (REA) and NOAA National Benthic Inventory (NBI) include observations of water quality, sediment quality, fish and shellfish tissue chemical contaminants, and benthic infaunal abundance obtained from studies conducted since 1991 by NOAA and partnering institutions ...

National Coastal Condition Report IV

This document contains the results and analysis from the fourth national coastal assessment, published in 2012 ...

NCCOS Long-term Monitoring Project: Regional Ecological Assessments and National Benthic Inventory

NOAA's National Centers for Coastal Ocean Science (NCCOS) works in partnership with other federal agencies and coastal states to conduct assessments of ecological condition and potential stressor impacts throughout our Nation’s estuaries, coastal-ocean waters, and NOAA protected areas; carry out ...

Numerical analysis of the primary processes controlling oxygen dynamics on the Louisiana shelf

The Louisiana shelf, in the northern Gulf of Mexico, receives large amounts of freshwater and nutrients from the Mississippi–Atchafalaya river system. These river inputs contribute to widespread bottom-water hypoxia every summer. In this study, we use a physical–biogeochemical model that ...

Phylogenetic analysis of Brachydinium capitatum (Dinophyceae) from the Gulf of Mexico indicates membership in the Kareniaceae

Brachidinium capitatum F. J. R. Taylor, typically considered a rare oceanic dinoflagellate, and one which has not been cultured, was observed at elevated abundances (up to 65 cells · mL?1) at a coastal station in the western Gulf of Mexico ...

Predicting harmful algal blooms: a case study with Dinophysis ovum in the Gulf of Mexico

Blooms of Dinophysis ovum and Mesodinium spp. have been observed in the Gulf of Mexico since 2007 using the Imaging FlowCytobot technology. Bloom dynamics of these two organisms in conjunction with ancillary environmental data for a 5-year period were analyzed ...

Processes controlling mid-water column oxygen minima over the Texas-Louisiana shelf

We investigate distributions of dissolved oxygen over the Texas-Louisiana shelf using spatially highly resolved observations in combination with a regional circulation model with simple oxygen dynamics. The observations were collected using a towed, undulating CTD during the Mechanisms Controlling Hypoxia ...

Relative role of wind forcing and riverine nutrient input on the extent of hypoxia in the northern Gulf of Mexico

Seasonal hypoxia of the northern Gulf of Mexico has been observed for more than 25 years. It is generally accepted that the variation in the areal extent of hypoxia is determined by changes in nutrient addition from the Mississippi River ...
