CRED Integrated Benthic Habitat Map for Tutuila Island,
American Samoa Year 2007
digital maps
http://www.soest.hawaii.edu/pibhmc/index.htm
This is an integrated benthic habitat map system which
consists of a number of separate map layers including
multibeam bathymetry, digital NOAA nautical charts,
acoustic backscatter imagery, hyperlinked underwater still
photographs and/or video framegrabs of the benthos,
seafloor classification results of living cover and
substrate from optical imagery and towboard diver
observations, derived depth contours, layers of geomorphic
information (slope, rugosity, Bathymetric Position Index
Structures, and Bathymetric Position Index Zones), Ikonos
satellite imagery where available, and terrestrial
topography. 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.
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.
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.

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.

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.

Geomorphology layers (slope, rugosity, Bathymetric Position
Index Strcutures and Zones) are derivates of multibeam
bathymetry. 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.
