48036 CMECS_Chlorophyll_metadata Data Set Published / External 37228 GulfRegion Project Completed 2012-05 These images were created by combining the mean surface chlorophyll estimates to produce seasonal representations for winter, spring, summer and fall. Winter includes the months of January, February and March; spring includes the months of April, May and June; summer includes the months of July, August and September; fall includes the months of October, November and December. Estimates of surface chlorophyll concentration were originally obtained from the Naval Research Laboratory at the Stennis Space Center (NRL/SSC). NRL/SSC processed MODIS-Aqua satellite imagery covering the Gulf of Mexico, for a 5-year time period from January 2005 through December 2009. The Gulf of Mexico was divided into three regions, western, central and eastern. For purposes of this image, the three regions were joined in ArcMAP 10. The surface chlorophyll estimates were determined using the OC3 algorithm for MODIS (O'Reilly et al., 2000). These estimates were then reclassified into phytoplankton productivity categories in accordance with the Coastal and Marine Ecological Classification Standard (CMECS). There are three CMECS categories under this parameter: oligotrophic (< 5 ug/L), mesotrophic (5 - < 50 ug/L), and eutrophic (> 50 ug/L). The mean surface concentrations for the northern Gulf of Mexico only fall into two of the three categories, oligotrophic (shown as blue) and mesotrophic (shown as green). This project was undertaken to assess the utility of satellite-derived products and modeled data for resource managers to characterize pelagic habitats in the absence of dense, time series in situ data. There were several steps involved in this process, including: identifying the most useful physicochemical parameters for characterizing the water column; assessing the fit of satellite-derived and modeled data as a proxy for in situ data; evaluating alternative, automated classification methodologies; querying resource managers for product improvement opportunities; and developing a practical example of a management application. Surface chlorophyll estimates were one of the satellite-derived products assessed as a proxy for in situ data. 10893 The NOAA Office for Coastal Management - Gulf Region received this data from another federal agency. Questions regarding the original data collection and/or processing should be directed to that agency (see lineage source citation).

The unique values were then manually reclassified into appropriate Coastal and Marine Ecological Classification Standard categories. Values were assigned to categories in accordance with the Coastal and Marine Ecological Classification Standard. not applicable Surface Chlorophyll Estimates Naval Research Laboratory, Stennis Space Center 2010-12-01 Range 2005-01 2009-12 Monthly means for 2005 through 2009 | Type of Source Media: external hard drive 1 Chlorophyll concentrations assigned in accordance with the Coastal and Marine Ecological Classification Standard. 2012-01-01T00:00:00 gov.noaa.nmfs.inport:48036 Anne Ball 2017-11-14T14:11:21 SysAdmin InPortAdmin 2025-05-15T19:15:57 2017-11-16 Office for Coastal Management OCM 1002 Public No No 2017-11-16 1 Year 2018-11-16
