Abstract:
Gridded bathymetry shelf, bank and slope environments of
Zealandia Bank, CNMI. Bottom coverage was achieved in depths
between ~12 and 285 meters, The Arc ASCII grid includes multibeam
bathymetry from the Simrad EM300 and Reson 8101 multibeam sonars
collected as of June 2007 by the NOAA Coral Reef Ecosystem
Division. The sonar frequencies are 30 and 240 kHz respectively.
Purpose:
The ASCII grid was created using data gathered
from multibeam soundings for use as a planning and reference
document. The data are also being used for benthic habitat
mapping, for locating Essential Fish Habitat, and for studying
geologic features of the area. Refer to supplemental information
for description of instrument and survey.
Supplemental_Information:
Multibeam data were collected aboard the NOAA Ship Hi'ialakai, a
218' United States National Oceanographic and Atmospheric
Administration research ship. 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, a
TSS/Applanix POS/MV Model 320, which measures position, velocity,
attitude and heading, and a Seabird SBE 9/11 plus CTD used to
measure sound velocity profiles.
Multibeam data were also 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. The R/V AHI's survey sensors include a 240 kHz RESON 8101-ER
sonar providing bathymetry and imagery data, a TSS/Applanix
POS/MV Model 320 which measures position, velocity, attitude and
heading, and a Seabird SBE 19 CTD used to measure sound velocity
profiles.
