AB: Three high school seniors from High Tech High (HTH) participated in the ALIA expedition that explored the Samoan hot spot track through seafloor mapping, rock sampling and the study of the water column above an active submarine volcano. The primary responsibility of the HTH participants focused on outreach and education, but they also were substantively involved in all scientific aspects of the cruise. Education and outreach activities included: maintaining the cruise website,the creation of ERESE digital library resources for earth science education, live video-conferences with students half a world away in San Diego, and offering tours of the Research Vessel Kilo Moana during an open house event organized with the Samoa Department of Eduation. At this occasion, the HTH seniors shared experiences and knowledge with the visiting Samoan elementary and high school students. Science involvement of the high school seniors included deck and laboratory work, by assisting with dredging, piston coring, rock cataloguing, casting CTDs, and computer programming. Three major computer programming efforts by the HTH seniors substantively supported the outreach activities and the science operations during ALIA. (1) The development of "CustomHTMLExport", a utility that allows for the export of photographs and their metadata into web pages and digital library collection. (2) The "CruiseWatch" featureson the ALIA website (http://earthref.org/ERESE/projects/ALIA/) that displays in near - real time key shipboard data such as the location on a map, geographic coordinates, ship speed, direction and wind speed and dredging data. (3) A dredge location simulator to predict the location of the dredge with respect to the ship and the seafloor which was made necessary for the safety of dredging due to the failure of pingers that normally are used to provide critical data for the location of the dredge with respect to the seafloor. The dredge location model is based a fluid dynamics approach and on a wide range of parameters that range from the bathymetry to the drag on the wire in the water. The latter was determined empirically from the wire angle during dynamic ship/winch operations. This model proved to be highly accurate, Our involvement with the ALIA expedition gave us some exciting perspectives on how scientific research is conducted at sea and the pleasure of having actually contributed to the expedition in terms of its science and outreach and education aspects. Our learning and science activities were shared with our peers at High Tech High as well as.
