040 Station ALOHA: A sentinel of open ocean change

For nearly three decades, Station ALOHA (22.75N, 158W) has served as a deep ocean field research site. Near-monthly sampling at this site began in 1988 with the creation of the Hawaii Ocean Time-series (HOT) program. Since that time, research at the field site has undergone remarkable expansion, with Station ALOHA now considered one of the best- studied locations in the world's oceans. The resulting observations enable detection and quantification of changes in ocean biogeochemistry, ecology, and hydrography in the North Pacific Subtropical Gyre, and provide insights into processes underlying these changes. Alongside the sustained near-monthly sampling carried out by the HOT program, ALOHA serves as a research site for implementing and testing autonomous and remote sensing platforms and sensors. The existing suite of observational platforms in place at ALOHA includes moorings, floats, a cabled observatory, and regular shipboard research expeditions. The outcome of this concerted research effort is an increased awareness of spatial and temporal variability in the oligotrophic ocean. This session will highlight ongoing research at Station ALOHA, inviting contributions describing temporal-spatial variability across a range of scales, particularly pertaining to ecosystem structure and function.
