7 1. Surface and subsurface turbidity (beam-c) range from 0.2–0.6 m -1 in op-area for today (04/01/11 19Z) and 0.4-0.5 m -1 tomorrow (04/02/11 19Z). 0.3–0.6 m -1 in op-area for 48 hour forecast (04/03/11 19Z). (See Slides 2,3,4) 2. Surface and subsurface diver visibility (horizontal) range from 26–79 feet in op-area for today (04/01/11 19Z) and 31-39 feet tomorrow (04/02/11 19Z). 26 – 39 feet in op-area for 48 hour forecast (04/03/11 19Z). (See Slides 2,3,4) 3. Sytem Performance: Today (04/01/11 19Z), tomorrow (04/02/11 19Z) and 48 Hour Forecast (04/03/11 19Z) expect ID and Detection over 100% in Q- Routes. 4. Today (04/01/11 19Z) predicted tow heights range from 30-36 feet and tomorrow (04/02/11 19Z) and 48 hour forecast (04/03/11 19Z) predicted tow heights range from 33-36 feet in Q-Routes. (See Slides 2,3,4) 5.Time Series at Surface for Location 30.05N and 86.1W: Horizontal Diver Visibility ranges from 43 to 60 feet during period starting 04/01/11 19Z to 4/3/11 19Z. Optimal Tow Height is ~33 feet during same 48 hour period yielding high probability of target ID. Surface currents during the same 48 hour period ranges from 0.5 to 2.8 knots. Summary Note: Good satellite scenes collected on 3/25/11 and 4/01/11.
