Long Term Measurments of Physical and Optical Properties with Profiling Floats

Optical sensors for oxygen and scattering plus chlorophyll fluorescence were added to APEX floats 0005 and 0015 to demonstrate the complementary information such instruments can provide to future ARGO-like programs. The APEX floats continuously monitor the upper 1000 meters of the ocean over several days, then surface to transmit data to national data centers via the satellite-based ARGOS system.

0005 was deployed in June 2004 in the North Atlantic at the mouth of the Labrador Sea. 0015 was deployed in August 2005 in the subpolar region of the North Pacific. 0005 ceased functioning in August 2007, after transmitting 221 profiles over a period of 38 months. 0015 continues to operate.
