Measurement of the heat content of the water. This is slightly different from sea surface temperature (SST) as measured by such satellites as AVHRR or MODIS. SST is a valid measurement for the upper skin of the ocean surface, typically the top 1 millimeter or less. The buoy water temperatures typically come in at a variety of depths, ranging from 1 to 50 meters.
Measurement of the heat content of the air.
Measurement of atmospheric pressure
The Practical Salinity Scale defines salinity in terms of the conductivity ratio of a sample to that of a solution of 32.4356 g of KCl at 15 degrees C in a 1 kg solution. A sample of seawater at 15 degrees C with a conductivity equal to this KCl solution has a salinity of exactly 35 practical salinity units (psu). A typical measurement far out in the ocean might be around 34.7, but near-shore measurements might be expected to be 31-32 due to fresh water discharge
How fast is the wind blowing.
Meteorological conventions (direction from which the wind blows, measured from true north).
Maximum measured 5-second wind speed over the observation interval.
Significant Wave Height:
The average height of the highest third of the waves.
Mean Wave Direction:
Maximum Wave Height:
Dominant Wave Period:
Dominant period is the period with maximum energy and is always either the swell period or the wind-wave period.
Magnitude of current velocity. If a buoy has been deployed for some time, one can see the effect of the daily tidal variation in the monthly and full deployment plots.
North Current Velocity:
Measured in Oceanographic conventions (direction into which the water flows, measured from true north). One can really see the effect of tidal variation on the current direction in the monthly and full deployment plots.
North Current Velocity:
North-south component of the ocean current.
East Current Velocity:
East-west component of the ocean current.
