Properties of water of interest Parameters, units, significance –Temperature –Salinity –Dissolved oxygen –Turbidity –Light levels –Depth…
Tools to measure these properties - depth Sounding lines –Problems… Pressure sensor Sonar
Tools to measure these properties - temperature Thermometer - Hg-based how to do at depth? - reversing
Tools to measure these properties - salinity Direct or indirect measurement Refractometer Conductivity sensor
Tools to measure these properties - turbidity Secchi disk transmissometer
Tools to measure these properties - dissolved oxygen Methods - chemical, electrical, optical Optode Polarigraphic electrode Winkler
Dissolved oxygen Concentration vs saturation Saturation - –expected amount given temp, pressure, salinity (ideal gas law) = 100% saturation –Under, over or at saturation –Units = % Concetration - units = mg/l (or ppm, mmol)
Dissolved oxygen nomographs Use nomographs to determine expected DO levels (100% saturation)
Dissolved oxygen nomographs use to determine saturation level
Example O 2 data
Tools to measure these properties - light What wavelengths? –Photosynthetically active radiation (PAR) sensor How to account for changes in incident light? –Deck sensor
Other parameters Chlorophyll levels - fluorometer
But these properties vary with depth Typical open ocean profiles Called - a hydrocast
Monitoring units Hydrolab/YSI = brands
Combined units moored, deployed, mobile CTD Argo floats
CTD hydrocast See our CTD hydrocast
Other oceanographic tools Water samplers –Nansen / Niskin bottle –messengers

Temperature. What is Temperature? Temperature is the measure of the average kinetic energy in a system. May be measured in Celsius (°C) or Fahrenheit.
Marine Instruments. Measuring and collecting tools.
What is salinity? What are the major sea salts? Salinity- the total quantity or concentration of all dissolved inorganic solids, or more precisely, ions.
Measuring pressure. Conductivity, Temperature and Depth (CTD) Despite the name, all CTDs actually measure pressure, which is not quite the same thing.
