Abstract:
Character string:
This image represents a LiDAR (Light Detection & Ranging) 0.3x0.3 meter resolution depth surface for Fish
Bay, St. John in the U.S. Virgin Islands (USVI). The image's horizontal coordinate system is NAD83 UTM 20
North. Fugro LADS, funded by the National Oceanic & Atmospheric Administration (NOAA) , acquired
bathymetry and relative seafloor reflectivity between 1/29/2011 - 2/28/2011. Bathymetry and reflectivity
data were acquired using a LADS (Laser Airborne Depth Sounder) Mark II Airborne System from altitudes
between 1,200 and 2,200ft at ground speeds between 140 and 175 knots. The 900 Hertz Nd: YAG (neodymium-doped
yttrium aluminum garnet) laser (1064 nm) acquired 3x3 meter spot spacing and 200% seabed coverage. Depths
between 3 and 40 m were surveyed, producing a 3x3 m bathymetry and 3x3 m reflectivity surface. These
surfaces were resampled to 0.3x0.3 m to match the spatial resolution of the orthophotos collected by the
U.S. Army Corps of Engineers in 2012. Environmental factors such as wind strength and direction, cloud
cover, water clarity and depth influenced the area of data acquisition on a daily basis. The data was
processed using the LADS Mark II Ground System and data visualization, quality control and final products
were created using CARIS HIPS and SIPS and CARIS BASE Editor. All users should individually evaluate the
suitability of this data according to their own needs and standards.
Purpose:
Character string:
This dataset was collected to update nautical charts in the area, and to support the characterization of
seafloor features in, and creation of a benthic habitat map for, Fish Bay, St. John in the U.S. Virgin
Islands (USVI). Habitat maps provide a spatially explicit representation of benthic structure and biological
cover. The spatial products developed for this project will: (1) inform local managers as to the current
distribution of resources, (2) provide a point of comparison for past and future mapping efforts, (3) help
locate sensitive marine communities, and (4) guide monitoring efforts and prioritize management actions.
