Abstract

THE HAWAII OCEAN TIME-SERIES (HOT) PROGRAM TURNS 25: HIGHLIGHTS OF A QUARTER CENTURY OF SUSTAINED OBSERVATIONS IN THE SEA

In October 2013, the Hawaii Ocean Time-series (HOT) program began its 25th year of sustained ocean measurements at the field site Station ALOHA (22.75N, 158W). The resulting time-resolved suite of measurements has fundamentally changed our view of ecosystem variability in the subtropical North Pacific. The emergent data highlight connectivity between ocean-climate, plankton ecology, and biogeochemistry over episodic to decadal time scales. The sustained, high quality observations have provided new insights into previously unrecognized ocean processes and have highlighted the necessity of interdisciplinary science to study variability in the ocean state. One reflection of the increasing value of these observations is the continued expansion of science conducted at Station ALOHA, including a diverse set of autonomous and remote sensing platforms and diverse science and education programs. This presentation will describe several key achievements from HOT, including how the program has contributed to our understanding of long-term trends in ocean carbon inventories and fluxes, documented previously unrecognized temporal variability in nutrient fluxes and inventories, and documented the important role of plankton community structure in carbon sequestration.
