New resource for teachers on how oceanographers take the pulse of ocean currents

This brochure produced originally at WHOI and recently refreshed at WHOI provides an overview of the OceanSITES effort.

One of the means by which we observe the ocean is to deploy moorings, lines with anchors on the seafloor and flotation along and/or at the top of the line. Instruments attached to the mooring line provide the means to sample the ocean as do instruments on surface floats if used. Data are recorded internally and available on recovery; in addition, data from instruments on surface buoys and data from ocean instruments with links to the surface are telemetered via satellite. International organization of moorings in the open ocean that are deployed again and again in order to collect long time series is done by the OceanSITES element of the Global Ocean Observing System.
