Station ALOHA is the focal point of a range of oceanographic studies conducted over great temporal scale that intend to understand and explain the trends of the greater North Pacific Ocean. Station ALOHA was established in 1988 at the start of A Long-term Oligotrophic Habitat Assessment (ALOHA) and this assessment continues today in many forms. The most extended form is the Hawaii Ocean Time-series (HOT) in which scientists from the University of Hawaii (UH) conduct 4 day research cruises to the site almost monthly. Scientists with HOT study the physical and biogeochemical properties of the site. In 2004, a collaboration between Woods Hole Oceanographic Institution (WHOI) and HOT PO, called the WHOI Hawaii Ocean Time-series Site (WHOTS), began deploying a mooring yearly to observe upper ocean-atmosphere interaction. Since 2008, sea gliders visit Station Aloha several times a year to add baseline data about the upper ocean to the already impressive pool of observations about this representative site. The newest and incarnation of ocean observation at Station ALOHA is the ALOHA Cabled Observatory (ACO), installed in June of 2011. With ACO, researchers at UH now have the ability to extract data from and send commands to instruments on the seafloor at Station ALOHA instantly and observe the little-seen habitat for years to come.
