In June 2009, a workshop was convened under the auspices of the Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) program to develop strategies for using observations and models to address the science questions articulated in the Open Science ...

Through its promotion of coordinated international research programs, the Intergovernmental Oceanographic Commission (IOC) has facilitated major progress on some of the most challenging problems in oceanography. Issues of global significance—such as general ocean circulation, the carbon cycle, the structure and ...

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 ...

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

This dataset provides seasonal spatial rasters of median predicted long-term (1978-2016) relative density of 47 marine bird species throughout the US Atlantic Outer Continental Shelf (OCS) and adjacent waters at a 2-km spatial resolution. Three indications of the uncertainty associated ...

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 ...

We report the zygotic encystment of geographically dispersed isolates in the dinoflagellate species complex Alexandrium tamarense, in particular, successful mating of toxic Group I and nontoxic Group III isolates. However, hypnozygotes produced in Group I/III co-cultures complete no more than ...

An ensemble smoother is used to estimate the initial conditions and mortality rates for a spatially explicit model of Alexandrium fundyense. The data assimilation procedure is effective at reducing model-data misfit in this strong constraint problem formulation. The skill of ...

The shift in marine resource management from a compartmentalized approach of dealing with resources on a species basis to an approach based on management of spatially defined ecosystems requires an accurate accounting of energy flow. The flow of energy from ...

In the Gulf of Maine area (GoMA), as elsewhere in the ocean, the organisms of greatest numerical abundance are microbes. Viruses in GoMA are largely cyanophages and bacteriophages, including podoviruses which lack tails. There is also evidence of Mimivirus and ...
