The Optical Tracer Injection System
(OTIS), an electronic data logging version of the
Chemical and Aqueous Transport (CAT) flow meter, is designed for
high resolution measurements in higher flow rate regimes, 0.2-1000m/yr,
and has potential for real time data acquisition. Like the CAT meter
the OTIS Meter measures aqueous flux at the seafloor by sealing around
an area of the sediment surface and channeling the flow from this area
through the instrument's flow tube. They differ, however, in the method
of flow measurement. |
