 Technical Information |
KEO mooring was developed at the Pacific Marine Environmental Laboratory (PMEL) and is essentially a Tropical Atmosphere Ocean (TAO) mooring modified for the harsh conditions of the Kuroshio Extension region. Special features of the KEO mooring that make it more robust include:
- Slack line with scope (mooring line / water depth) of 1.4
- Sonic anemometer
- Modifications to the buoy platform and mooring line for added buoyancy and reduced drag
- Increased anchor weight
As part of the global network of time series reference sites, the KEO project office encourages wide use of the data and welcomes collaborations. In particular,
- All data are freely available
- Daily-averaged and spot measurements are telemetered to shore in near-realtime and made available within one day (see "Data")
- A subset of the surface telemetered measurements are also made available in near-realtime through the GTS beginning Sept 2007
- High resolution data are available in delay mode within 6 months of sensor recovery
- KEO carries an extensive suite of surface and subsurface sensors to monitor air-sea heat, moisture, and momentum fluxes; and surface and subsurface temperature and salinity. Beginning June 2005, KEO will also monitor ocean currents and air-sea CO2 flux.
