1994 LEO-15 Deployments

1994 Contents:

1. Instrument platforms
2. Overviews:
• Entire June deployment. This shows 1 and 5 mhz ABSS backscattered intensities plotted with the relevant environmental forcing parameters for the entire June segement of this deployment.
• Entire MAY deployment 1and 5 mHz ABSS, VACM wave speeds, current speed, temp, salinity, and winds.
3. One day ABSS record showing bedform evolution during a storm on June 28th.
4. Eighty second record from the narrow beam (3cm footprint) ABSS system showing a high resolution view of active sediment resuspension during the June 28th storm. High frequency data from the wider (60cm footprint) beamwidth ABS .
5. Upper water column scatterers imaged by the upward looking 1MHz sonar on May 25th. are most likely to be biological scatterers since there is not sufficient wave and current activity to suspend sediment as seen by the downward looking sonar. If so what type of creatures are they??
6. A Movie showing a "front" as indicated by a rise the in tempertaure and a corresponding drop in salinty with a convergence of biological scatterers near May 25th. Here is another movie showing a similar event during the June deployment.
• Image showing ABS and time series as this front passes by on May 24.8.
• Here is an imageof a similar sequence of events from the june deployment.
7. Near surface scatterers on may 25 19hrs. These look more like wave injected bubbles.
