Collaborative Bathymetric Survey of Honolulu Harbor Completed

Mapping specialists in the Coral Reef Ecosystem Division (CRED) collaborated with NOAA’s Office of Coast Survey (OCS) and the U.S. Army Corps of Engineers during April–May 2009 to resurvey bottom depths of Honolulu Harbor and approaches used by large vessels to enter and leave the harbor. Data collected during this multi-beam sonar survey will be used to update and validate nautical charts and maps of nearshore benthic habitat in the area.

During the three week survey all sonar systems aboard NOAA's 25' survey launch, R/V Ahi, were thoroughly tested and documented. In addition, new members of CRED's mapping team were trained in preparation for benthic habitat mapping surveys in the main Hawaiian Islands, Guam and the Commonwealth of the Northern Mariana Islands. The Honolulu Harbor bathymetric data, which are being processed by OCS, are expected to be available in September 2009. This work continues the collaboration by CRCP and CRED in support of NOAA's Integrated Ocean and Coastal Mapping Program.
