Fugro Pelagos, Inc., under contract to the National Oceanic and
Atmospheric Administration (NOAA) Hydrographic Services Division,
used Airborne Lidar Hydrography to survey the nearshore waters and
offshore reefs surrounding St. Paul and St. George Islands of the
Pribilof Islands in Alaska. The Pribilof Islands are remote islands
in the Bering Sea. The survey extended from the shoreline to 20
meters and was conducted for nautical charting purposes. Fugro Pelagos
utilized the SHOALS-400 system, owned by the United States Army
Corps of Engineers (USACE) and operated by Fugro Chance.
The Airborne Lidar Bathymetry approach required flying
the SHOALS-400 system aboard a Twin-Otter aircraft, with DGPS and
inertial motion control. Processing was completed using the SHOALS
processor for acquired data and tide data were collected in accordance
with NOAA standards. Final data processing and reporting were completed
using CARIS HIPS, after CARIS was contracted by Fugro to develop
SHOALS-400 support within CARIS HIPS.
