Salinity and temperature observations: Sea-water temperature (degrees C), conductivity (S/m), salinity (psu) and sigma-theta (kg/m³) are shown at all sites. Surface-buoy observations were collected at the surface and at mid-water. Tripod observations were made near the bottom. A combined plot of all observations is also provided. Significant wave height is also included to provide an indication of wave energy.

Unfiltered water-flow observations: Unfiltered water-flow observations (cm/s) at individual sites are shown at the surface and at the bottom. Observations are from RD Instruments' Workhorse ADCPs. At all sites, the surface is the upper-most bin at which measurements were not greatly affected by waves or tides. Significant wave height is also shown to provide an indication of wave energy.

Unfiltered pressure observations: Unfiltered pressure observations are shown at individual sites. Pressure (Pa) measured by an ADCP is shown in panel 2. Pressure (dbar) measured by an external pressure sensor is shown in panel 3. Pressure (mbar) measured by an external pressure sensor that was attached to an ADV or PCADP is shown in panel 4. Significant wave height (m) from each site is shown in panel 1 to provide an indication of wave energy.

Unfiltered surface-wave observations: Water level (m), significant wave height (m), peak wave period (s), maximum wave height (m), mean wave period (s), and peak wave direction from which waves are propagating, measured clockwise from north, are shown at individual sites.

Unfiltered Acoustic Doppler Velocimeter (ADV) observations: Unfiltered distance of measurement location above the sea floor (m), water flow (cm/s) and the standard deviation of water flow (cm/s), near the sea floor. All observations are from Sontek ADVs. Significant wave height (m) from each site is also shown to provide an indication of wave energy.

Unfiltered Pulse-Coherent Acoustic Doppler Profiler (PCADP): Unfiltered distance from the sea floor (m), water flow (cm/s), and the standard deviation of water flow (cm/s) near the sea floor is shown. All observations are from Sontek PCADPs. Significant wave height (m) from each site is also shown to provide an indication of wave energy.

Unfiltered Acoustic Backscatter Sensor (ABS) observations: Burst-mean statistics calculated from ABS data at North Flobee, North Minipod, South Flobee, and Tip Micropod. Statistics include the burst-mean for the three ABS transducers. For the ABS data, both pdf and png versions are provided. (Please note that because these figures are complex, the pdf version may load slowly.)

Unfiltered Optical Backscatter Sensor (OBS) observations:

Animation of Sonar Data: The changing condition of the sediment bed at the North Minipod can be viewed as animation using a media player that supports .avi files. In the top panel of the animation, backscatter intensity of the sediment bed is shown in the grayscale image, with ADV current speed noted in red. ADV current speed and direction are also indicated by the magnitude and orientation, respectively, of the red arrow. An estimate of sea-floor ripple wavelenth and the direction towards which ripples are propagating are noted in cyan. The orientation of the cyan arrow indicates the wave direction, whereas the magnitude of the cyan arrow indicates the estimate of sea-floor ripple wavelength. This magnitude has been multiplied by five for visual purposes. The bottom panel shows significant wave height at the North Minipod. The red dot in this panel coincides with the time provided in the image in the top panel.
