These data are incorporated into stand alone ArcGIS and ArcReader projects. ArcReader is a software package that can be downloaded and installed free of charge, and enables the user to view and perform limited manipulations of these map layers. Purpose: These benthic habitat map systems are independent ArcGIS and ArcReader projects that include layers of a wide range of biologically important characteristics of the coral reef ecosystem around the island of Tutuila in American Samoa. They make these data available to scientists and resource managers to enable them to develop unique combinations of data to address specific management and research questions. Supplemental_Information: Tutuila is the largest of seven islands in American Samoa at 142.3 sq. km. Volcanic in origin, it reaches a height of 653m at Matafao Peak. Tutuila is centered at 14.30 S, 169.75 W, has approximately 101.3 km of coastline and an estimated 36.2 sq. km of reef area. The port of Pago Pago is a collapsed crater and is one of the largest natural ports in the Pacific. Pago Pago contains a tuna cannery which is a hub of a large purse-seining tuna fishing fleet. The cannery outputs large amounts of nutrients as byproduct into the waters of Pago Pago Harbor. The human population of Tutuila in 1990 was 45,043. It is classified as a basaltic or a high island and contributes significant nutrient and sediment runoff to coastal waters. Tutuila's waters include the 0.7 sq. km Fagatele Bay National Marine Sanctuary, as well as by the National Park of American Samoa, which covers the north-central part of the island and ~5 sq. km of coastline. Cruises CoRIS Metadata Record Names TC0201 cred_toad_tutuila_2002 OES0402 cred_toad_tutuila_2004 Multibeam data were collected aboard the R/V AHI (Acoustic Habitat Investigator), a 25' survey launch owned and operated by the NOAA Pacific Islands Fisheries Science Center in Honolulu, HI, and aboard the NOAA Ship Hi'ialakai, a 218' United States National Oceanographic and Atmospheric Administration research ship. The R/V AHI's survey sensors include a 240 kHz Reson 8101-ER, the sonar providing multibeam bathymetry and backscatter data, and a Seabird SBE 19 CTD used to measure sound velocity profiles, whereas the NOAA Ship Hi'ialakai's survey sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad EM3002d sonar, which provide bathymetry and imagery data, and a Seabird SBE 9/11 plus CTD used to measure sound velocity profiles. Both systems include a TSS/Applanix POS/MV Model 320 which measures position, velocity, attitude and heading. Specific equipment configurations are documented in metadata from cruises: AHI0402, AHI0602, TC0201 and OES0402. These metadata can be accessed at: http://www.soest.hawaii.edu/pibhmc/pibhmc_cruise- catalog.htm Optical imagery of the seafloor is collected primarily to validate the interpretation of benthic habitat characteristics from multibeam echosounder surveys. Optical data were collected using two different methods. In shallow waters of depths between a few meters and 20-30 m, towboard divers with the Coral Reef Ecosystem Division (CRED) collect video or still imagery while being towed behind a small boat over track lines pre-programmed into a handheld GPS unit. The majority of seafloor in the area is deeper than the approximately 30 m maximum depth attainable by towboard divers. The habitat in these deeper areas is assessed by Towed Optical Assessment Device (TOAD), a sled equipped with underwater video camera, still camera, and lights. Camera sled deployments were conducted at night, usually between 1800 and midnight, to avoid interfering with daytime small boat and diver operations. The TOAD was originally deployed from a pot hauler mounted on the starboard side of the fantail on NOAA Ship Townsend Cromwell. On the NOAA Ships O.E. Sette and Hi'ialakai various iterations of TOADs were deployed off the portside J-frame amidships or the starboard side J-frame respectively. In all cases the sleds were lowered slowly to the bottom by the deck crew with the use of a capstan. The TOAD operator monitored a live video feed from the camera and began recording data on two video tape recorders. When the camera reached bottom the deck crew was notified by radio to stop lowering, and the ship moved off along a predetermined course, towing the TOAD astern for the first TOAD, or by drifting with subsequent camera sleds. The operator continued to monitor the vehicle and provided commands to raise or lower it to keep the camera just above the bottom.

These layers may be used for benthic and essential fish habitat characterization, and for the study of geologic features. By combining the dataset with bathymetry, backscatter, other derivatives, and in situ data, they collectively compose benthic habitat maps which are designed to be used to understand and predict moderate depth (~20m - 150m) benthic habitats for different organisms that inhabit coral reef ecosystems.
