      Abstract: 
        Chlorophyll-a, is a widely used proxy for phytoplankton biomass and an 
        indicator for changes in phytoplankton production. As an essential 
        source of energy in the marine environment, the extent and 
        availability of phytoplankton biomass can be highly influential for 
        fisheries production and dictate trophic structure in marine 
        ecosystems. Changes in phytoplankton biomass are predominantly 
        effected by changes in nutrient availability, through either natural 
        (e.g., turbulent ocean mixing) or anthropogenic (e.g., agricultural 
        runoff) processes. This layer represents the maximum monthly 
        climatological mean of chlorophyll-a (mg/m3) from 1998-2018.
        
        Data products generated by the Ocean Colour component of the European 
        Space Agency (ESA) Climate Change Initiative (CCI) project. These 
        files are 8-day 4-km composites of merged sensor products: Global Area 
        Coverage (GAC), Local Area Coverage (LAC), MEdium Resolution Imaging 
        Spectrometer (MERIS), Moderate Resolution Imaging Spectroradiometer 
        (MODIS) Aqua, Ocean and Land Colour Instrument (OLCI), Sea-viewing 
        Wide Field-of-view Sensor (SeaWiFS), and Visible Infrared Imaging 
        Radiometer Suite (VIIRS).
        
        A quality control mask was applied to remove spurious data associated 
        with shallow water, following Gove et al., 2013. Monthly climatologies 
        were calculated from monthly time series averaging for all same-months 
        (e.g., January). Nearshore map pixels with no data were filled with 
        values from the nearest neighboring valid offshore pixel by using a 
        grid of points and the Near Analysis tool in ArcGIS then converting 
        points to raster.

      Purpose: 
        These layers were developed as part of a geospatial database of key 
        anthropogenic and environmental pressures to coastal waters of 
        American Samoa.

      Abstract: 
        Chlorophyll-a, is a widely used proxy for phytoplankton biomass and an 
        indicator for changes in phytoplankton production. As an essential 
        source of energy in the marine environment, the extent and 
        availability of phytoplankton biomass can be highly influential for 
        fisheries production and dictate trophic structure in marine 
        ecosystems. Changes in phytoplankton biomass are predominantly 
        effected by changes in nutrient availability, through either natural 
        (e.g., turbulent ocean mixing) or anthropogenic (e.g., agricultural 
        runoff) processes. This layer represents the maximum monthly 
        climatological mean of chlorophyll-a (mg/m3) from 1998-2018.
        
        Data products generated by the Ocean Colour component of the European 
        Space Agency (ESA) Climate Change Initiative (CCI) project. These 
        files are 8-day 4-km composites of merged sensor products: Global Area 
        Coverage (GAC), Local Area Coverage (LAC), MEdium Resolution Imaging 
        Spectrometer (MERIS), Moderate Resolution Imaging Spectroradiometer 
        (MODIS) Aqua, Ocean and Land Colour Instrument (OLCI), Sea-viewing 
        Wide Field-of-view Sensor (SeaWiFS), and Visible Infrared Imaging 
        Radiometer Suite (VIIRS).
        
        A quality control mask was applied to remove spurious data associated 
        with shallow water, following Gove et al., 2013. Monthly climatologies 
        were calculated from monthly time series averaging for all same-months 
        (e.g., January). Nearshore map pixels with no data were filled with 
        values from the nearest neighboring valid offshore pixel by using a 
        grid of points and the Near Analysis tool in ArcGIS then converting 
        points to raster.

      Abstract: 
        Chlorophyll-a, is a widely used proxy for phytoplankton biomass and an 
        indicator for changes in phytoplankton production. As an essential 
        source of energy in the marine environment, the extent and 
        availability of phytoplankton biomass can be highly influential for 
        fisheries production and dictate trophic structure in marine 
        ecosystems. Changes in phytoplankton biomass are predominantly 
        effected by changes in nutrient availability, through either natural 
        (e.g., turbulent ocean mixing) or anthropogenic (e.g., agricultural 
        runoff) processes. This layer represents the maximum monthly 
        climatological mean of chlorophyll-a (mg/m3) from 1998-2018.
        
        Data products generated by the Ocean Colour component of the European 
        Space Agency (ESA) Climate Change Initiative (CCI) project. These 
        files are 8-day 4-km composites of merged sensor products: Global Area 
        Coverage (GAC), Local Area Coverage (LAC), MEdium Resolution Imaging 
        Spectrometer (MERIS), Moderate Resolution Imaging Spectroradiometer 
        (MODIS) Aqua, Ocean and Land Colour Instrument (OLCI), Sea-viewing 
        Wide Field-of-view Sensor (SeaWiFS), and Visible Infrared Imaging 
        Radiometer Suite (VIIRS).
        
        A quality control mask was applied to remove spurious data associated 
        with shallow water, following Gove et al., 2013. Monthly climatologies 
        were calculated from monthly time series averaging for all same-months 
        (e.g., January). Nearshore map pixels with no data were filled with 
        values from the nearest neighboring valid offshore pixel by using a 
        grid of points and the Near Analysis tool in ArcGIS then converting 
        points to raster.

                Use of WMS-C is similar to traditional WMS but with the 
                addition of the "tiled=true" parameter, which triggers 
                GeoServer to pull map tiles from GeoWebCache if they have been 
                previously generated. This can dramatically improve 
                performance, especially for larger datasets. Supported map 
                formats include JPEG and PNG. Supported info formats include 
                GeoJSON, GML, HTML, and plain text.
