WHOI, Woods Hole, MA

Data: Velocity, Turbidity, Correlated Quantities, Pressure, Temperature

Velocity

Vector velocity at 5 heights from 30 cm to 500 cm above bottom, half hour means from 4 Hz measurements

Burst velocities at 10 Hz for 1 height daily for 40 minutes

Turbidity

Optical backscatter sensor measurements at 5 heights from 30 cm to 500 cm above bottom, half-hourly means

Correlated Quantities

velocity-turbidity, half-hourly means: "sediment flux"

velocity-velocity half-hourly means "turbulent kinetic energy, "Reynolds stress"

Pressure

Half-hourly bursts of 1 minute duration, pressure measurements at 4 Hz.

Temperature

Half-hourly means of temperature at 5 heights from 30 cm to 500 cm above bottom.
