HMRG is developing techniquesto process multibeam

backscatter/imagery datausing software developed at

University of Hawaii.Backscatter provides

additional information about the character of the seafloor.

All data are being submitted to NOAA’s Office of Coast Survey

for evaluation for possible chart updates.

What’s Next?What’s Next?• Complete bathymetry processing -- grids available on web –

Oct 2004• Proposal through Joint Institute for Marine and Atmospheric

Research using CEROS contracting vehicle to form Pacific Islands Benthic Habitat Mapping Center at the University of Hawaii – expected funding in October 2004. Mapping center will support operations on Kilo Moana, Sette, Hi’ialakai and AHI.

• Continue processing of backscatter at mapping center• Submission of data/metadata to NGDC & CoRIS• Submission of all data to NOS Office of Coast Survey for

possible inclusion into Pacific charts. • Installation of two multibeam sonars on NOAA Ship

Hi’ialakai for mapping in the U.S. Pacific Islands – Mar 2005• Up to 150 mapping days in FY’05. Expansion of NOAA

mapping operations to Main Hawaiian Islands
