Abstract

THE HOT PROGRAM PRESENTS: A CARBON CAROL: GHOSTS OF CO2 PAST, CO2 PRESENT AND CO2 YET TO COME

Long before the Hawaii Ocean Time-series (HOT) program was born and Station ALOHA placed on the chart, the oceans were absorbing excess CO2 from the growing atmospheric reservoir. Yet, direct physical evidence documenting the oceanic response to this anthropogenic perturbation would only come with long-term, sustained measurement programs operating with a high level of accuracy, precision and persistence. Here, we will take you on a journey that begins with our state of knowledge of the inorganic carbon system in the North Pacific subtropical gyre prior to HOT. Next, we will advance through 25 years of data collection by a host of characters and witness their successive endeavors to interpret the results. Having reached the present, we will put forward our current trend estimates for CO2 system parameters at Station ALOHA. Finally, we will consider the potential futures of CO2 at ALOHA and of the HOT CO2 measurement program. Throughout this reflection, both the critical role of ocean time-series programs in documenting global change and the need for continuous improvement within such programs will be evidenced.
