A wide range of instruments can be employed to measure current speed and direction; water temperature, conductivity, and depth; turbidity and suspended sediment concentrations; wave characteristics; near-bottom turbulence; and sea-floor topography in the coastal ocean. The measurement resolution and accuracy depends on the sensor deployed; consult the manufacturer’s specification as needed. Most of the instruments deployed are powered by batteries, though in a few cases power is supplied externally. Data are always logged internally during a deployment, but telemetry may also be used to recover data in near real time.
