A 12-bottle CTD sits ready for deployment to 5000 m aboard the R/V Oceanus at Station ALOHA (A Long Term Oligotrophic Habitat Assessment) 100 km north of Oahu, Hawaii to collect water samples for the Hawaii Ocean Timeseries (HOT). Station ALOHA is the site for HOT's 27-year long-term oceanographic research study. This photo was taken on the 284th HOT research cruise. Yellow floats for a bottom-moored sediment trap array (deployed the following morning) can be seen at the bottom right of the photo.

Station ALOHA is a circle of 6 mile radius north of Hawaii in the Pacific Ocean where varied oceanographic research projects converge to produce a remarkable collection of observations about our dynamic oceans and atmosphere. The Hawaii Ocean Time series started in 1988, and has collected 1,072,080 liters of seawater from 5,096 CTD casts during 284 research cruises aboard 16 different research vessels. Among a vast plethora of oceanographic and atmospheric data, 70,066 salinity and 29,279 oxygen samples have been processed. Station ALOHA is also home to the Woods Hole HOT (WHOTS) buoy and the ALOHA Cabled Observatory (ACO). Visit the Station ALOHA website for more information: http://aloha.manoa.hawaii.edu.
