Data, environmental assessments and other products developed by the Branch provide managers, scientists and stakeholders with up-to-date information. These products are used to help conserve the nation's marine resources and to define the level of damage to those resources when natural or human caused disasters occur.

HAB Bulletin Archive
Gulf of Mexico Harmful Algal Bloom bulletin from November 13, 2002. Bulletins shows chlorophyll concentration, wind conditions, and analysis.
The HAB bulletin provides timely information to the management community in the Gulf of Mexico during a bloom event. The near real-time bulletins provide interpreted data that include wind speed and direction information, and a chlorophyll image from the OrbView-2/Sea-viewing Wide Field of view Sensor (SeaWiFS) satellite. The bulletin is a collaborative effort of the National Ocean Service Center for Coastal Monitoring and Assessment, NOAA CoastWatch, and the NOAA Coastal Services Center.
To access the archived HAB bulletins, please go to the CoastWatch Harmful Algal Bloom Bulletin home page. Archived HAB bulletins are available in PDF format, which requires Adobe Acrobat Reader for viewing (click here to download this free software ).
The Remote Sensing Team has created several processed SeaWiFs products. For more information, please contact Richard.Stumpf@noaa.gov
Satellite imagery can also be obtained at the National Environmental Satellite, Data, and Information Service (NESDIS) website. To download SST, wind, and ocean color data, please visit the NOAA CoastWatch website.
NWHI: Maps and Imagery
The Remote Sensing Team led development of the first benthic habitat maps made for the Northwest Hawaiian Islands. The NWHI chain extends across 2200 km of open ocean, and the total shallow water area of the ten atolls encompasses over 8,000 square km. Due to the remoteness and large spatial extent of these reefs, high-resolution satellite imagery was the primary source of data for this effort. Field data collected during a NOS cruise to NWHI in Aug-Sep 2001 and provided by the NMFS, Honolulu Lab were also essential to map production. The satellite data used was IKONOS multispectral (blue/green/red/near-infrared bands) and panchromatic imagery from Space Imaging, collected between 2000 and 2002.
Landsat 7 Enhanced Thematic Mapper Plus (ETM+) imagery was also obtained for all ten atolls as well as for most of the bank areas.
Map products for NWHI include georeferenced truecolor images derived from IKONOS satellite data, estimated bathymetry (in meters) derived from the imagery, benthic habitat cover, and detailed benthic habitat classes. The process of map development is described in detail in NWHI_map_development.pdf and a description of the classification scheme and classes can be found in NWHI_class_scheme.pdf. A PDF file with larger versions of the colorbars for the depth scales and the legends for habitat cover and detailed class is also available: NWHI_map_legend.pdf.
