AB: The USCG Healy (WAGB-20) is the US academic research vessel supporting Arctic research. Healy has supported a dozen science programs in the Arctic starting in the boreal summer of 2001 with a cruise to the Gakkel Ridge. Significant upgrades were implemented prior to the 2004 Arctic field season including a significantly improved science seawater system, enhancements to computer infrastructure, installation of a POS/MV-320 GPS aided inertial navigation and attitude sensor and installation of an Iridium-based email system. Upgrades prior to the 2005 field season included installation of substantially improved four-channel, load equalizing Iridium network connection, and installation of a prototype watchstander workstation. The enhanced Iridium system provides reliable, fast-turnaround email even when operating at the highest latitudes. The watchstander workstation provides an ergonomic arrangement for underway watchstanders, significantly improved displays and new software linking a real-time GIS displays on workstations in the computer Lab. Perhaps the most significant improvements were in data acquisition, display, transfer ashore in real-time and archiving. Future upgrades in various stages of planning include upgrades to the Computer Lab, Future Lab, Aft Staging and Meteorology Lab which will provide improved efficiency and space utilization, a more reliable underway thermosalinograph installation for operation when in ice, improvements to the science seawater system, improved performance of the reefers and climate controlled chambers, upgrade or replacement of the multibeam seafloor mapping system, improvements to the operation and maintainability of the subbottom profilers , and enhancements to the data acquisition, quality control and real-time monitoring capabilities among other things.
