Real-time Meteorological Observations

From January 1997 to October 2000, a physical-biogeochemical mooring was deployed to obtain continuous measurements of various atmospheric and oceanographic parameters. The mooring was located at 22° 28'N, 158° 8' W and was designated as Station HALE-ALOHA.

In August 2004, HALE-ALOHA was redeployed at a site 6 nautical miles west of Station ALOHA (22° 46'N, 158° 5.5'W ) as part of the Multi-diciplinary Ocean Sensors for Environmental Analyses and Networks (MOSEAN) project. MOSEAN is directed toward new technologies that will lead to increased observations that are essential for solving a variety of interdiciplinary oceanographic problems. These include: biogeochemical cycling, climate change effects, ocean pollution, harmful algal blooms (HABs), ocean ecology and underwater visibility. This site is a collaboration with the University of California Santa Barbara and WET Labs.
