The information presented is a combination of standard CRED monitoring summary data and more specific layers generated by request from resource managers and scientists in American Samoa. The fish and benthos data were collected either by rapid ecological assessment (REA) surveys conducted during 2010, or by towed-diver surveys conducted during 2008 and 2010. The map is accompanied by the summary data used to generate the data layers (as excel attachments) and is available in the form of an interactive pdf with layers to make it usable by those without GIS access. The information layers included in this interactive PDF were initially developed to augment the existing Biogeographic Characterization and Marine Protected Area (MPA) network design analysis conducted by the NOAA National Centers for Coastal Ocean Science (NCCOS). The NCCOS analysis and this product contribute to the Territory's overall goal to protect 20% of the territorial coral reefs as no-take MPAs to protect key coral reef species, and the layers are of particular interest to local resource managers as they are key ecosystem components that affect ecosystem processes, and therefore are essential to design the most effective MPA network.

The survey sites were randomly selected using a systematic process based on available habitat and bathymetric data. However, although efforts are made to include broad spatial coverage, weather conditions and other environmental constraints may have prevented the team from surveying exposed reef areas. The same methods of data collection were used at each of the sites surveyed at this location, and scientists/divers are required to complete training and pass identification examinations prior to conducting surveys. Divers typically enter their data into a database and perform quality assurance and control checks on the same day the data were collected. Data are examined for diver bias, outliers, and other discrepancies. Following a mission, data are processed, run through a series of validation checks, and then migrated into CRED’s master database. Unless specified as towed survey data, all data presented were collected by rapid ecological assessments during the NOAA CRED cruise to American Samoa in 2010. Using CRED habitat and bathymetric maps, survey sites (< 30m in depth) on hard-bottomed habitat were selected using a random, depth stratified design. At each site, the fish assemblage was surveyed using a stationary point count (SPC) method. Details of the method are available (see Ault et al. 2006, Williams et al. 2011, Ayotte et al. 2011 [http://www.pifsc.noaa.gov/library/pubs/admin/PIFSC_Admin_Rep_11-08.pdf]), but in brief, for each survey a pair of divers record the number, size and species of all fishes observed within adjacent visually estimated 15m-diameter cylinders. Fish abundance and size data were used to calculate fish biomass using species-specific length-weight conversion factors. Those factors and the formula used to generate weight estimates are available in Heenan et al. 2014 (http://www.pifsc.noaa.gov/library/pubs/DR-14-003.pdf). At each site, a photo-transect was collected spanning the diameters of the adjacent SPC cylinder (30 photos at each site). These photos were then used to estimate planar percentage cover of benthic substrates using the point count method in Coral Point Count (CPCe [http://www.nova.edu/ocean/cpce/], a freely available tool, Kohler et al. 2006). Towed diver surveys involve a small boat towing two SCUBA divers. The divers work as a benthic and fish pair, with the fish diver recording the species, number, size and time in the survey, when large-bodied (>50 cm total length) reef fish are observed. The tow-track, together with a layback algorithm, and the time of observation are then used to estimate the geographic coordinates of sightings. This method supplements the SPC surveys by allowing for coverage of large areas of habitat that are necessary to adequately sample the generally rare and or clumped large-bodied reef fish species that are not well captured by small-scale comprehensive surveys (Richards et al. 2011). The fish data presented here were collected during towed surveys conducted during the NOAA-CRED 2010 cruise. Finally, towed benthic data collected during the 2008 cruise is also presented, as that was deemed the best information CRED has on the location of large coral colonies (> 2 m in diameter), which were noted by the towed-benthic divers during that cruise. 2011-12-16T00:00:00 annually This metadata was automatically generated from the FGDC Biological Data Profile of the Content Standard for Digital Geospatial Metadata standard (version FGDC-STD-001.1-1999) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
