    • PHYSICAL OCEANOGRAPHIC RESEARCH EQUIPMENT
    • TEMPERATURE
      • thermometer :
      • measures temperature
    • TEMPERATURE
      • CTD - conductivity, temperature, depth :
      • measures temperature as well as electrical conductivity (salinity)
    • weather vane - measures wind direction anemometer – measures wind speed WIND
    • CURRENT SPEED
      • current meter
    • TIDE HEIGHT
      • tide gauge -
      • measures
      • height of tide
    • TIDE HEIGHT
    • MOORED BUOYS fixed in one location
    • MOORED BUOYS
      • have instruments on them to
      • measure:
          • air and water temperature
          • current speed & direction
          • salinity
          • wind speed & direction
    • buoy system in Pacific Ocean to measure for El Nino
    • DRIFTING BUOYS float in water to measure current speed and direction
    • DRIFTING BUOYS
    • DRIFTING BUOYS unintentional
    • SATELLITES
      • can measure:
      • currents
      • sea surface height
      • ocean topography
      • sea surface temperature
      • turbidity
      • cholorphyll
    • SATELLITES
    • SATELLITES
    • CHEMICAL TRACERS
      • artificial substances
      • date of production or release known
      • like a dye – can follow flow of currents
      • especially useful to follow thermohaline
      • circulation
