Ocean Atmosphere  18:06 Methods of measuring currents indirectly—taking some data and insert into  formulas/ theory Indirect Methods: Ekman currents/transport: need wind data from buoys, ships, and satellites Geostrophy= Balance between pressure and Coriolis forces: need satellite  altimetry or ship-based CTD data Measurements of ocean dynamic topography (SSH) across the world ocean  contribute to a wide range of scientific activities, including determination of sea  level, calculation of Earth’s geoids, estimation of geostrophic currents,  measurements of tides and waves and many others Intro to surface currents and circulation: On average currents move at 1 meter per second; faster currents travel at 2.5  meters/second; slower currents just as California current move at .5  meters/second Currents deflect to right in NH (left in SH) Why? Upper ocean currents driven by winds
