AB: The USCG Healy (WAGB-20) is the US academic research vessel supporting arctic research. The Healy's keel was laid at Avondale shipyard in 1996. An extensive science evaluation coordinated by the UNOLS Office was conducted in 2000. The first science legs were conducted in 2001 and the status of the Healy was reported by Swift et. al (2002) in EOS. Since then the UNOLS Arctic Icebreaker Coordinating Committee has worked with the Coast Guard, the ship, the National Science Foundation and the user community to encourage a number of significant improvements which have been made to the vessel including substantial upgrades to the science data acquisition and logging system, installation of a significantly improved science seawater system, installation of a dual frequency echo sounder with swept (Chirp) subbottom capability replacement of the 300 KHz ADCP with a 75 KHz broad band ADCP, substantial upgrades to the ship's satellite data receiving system and numerous communication system upgrades. Future upgrades in various stages of planning include upgrades to the lab spaces for improved efficiency and space utilization, improvements in the climate control chambers, more cooling water for incubators, upgrade or replacement of the multibeam seafloor mapping system, improved high latitude communications, and enhancements to the data acquisition, quality control and real-time monitoring capabilities among other things.
