In March 2013, the completed its 250th research expedition to its open ocean field site. After nearly 25 years of near-monthly sampling, HOT program measurements serve as an important barometer of global change, providing unprecedented views on changes to the subtropical North Pacific Ocean.
HOT is based at the , and is supported by research grants from the .
The project has logged more than 1,000 days at sea, providing opportunities for students and researchers at UH and aboard to engage in oceanographic field research.
“It is really satisfying to reach this milestone, and to see the growing importance of the HOT program accomplishments. We initially thought 5 years, maybe 10. Here we are at 25 years and counting,” said David Karl, UH Mānoa oceanography professor and director of the . “Each additional year of observations brings us closer to a fundamental understanding of how the ocean functions and its relationships to climate.”
