ALOHA Cabled Observatory uses old cable for new information
Courtesy: Hawaii News Now60 miles north of Oahu, and 3 miles deep into the ocean is the Aloha Cabled Observatory (ACO), the world deepest unmanned oceanographic science platform at Station Aloha. Brian Chee explained how the older trans-Pacific AT&T cables are being used for oceanographic science.
The ACO collects a stream of constant, real-time data that measures water pressure, oxygen levels, currents, temperature, salinity and more. This wealth of information can shed light on issues ranging from climate change to earthquakes. The ACO even boasts live video and hydrophone capabilities, allowing researchers to record the songs of the migrating humpback whales that spawn in Hawaiian waters every winter.
