SB Channel

The 2008 RaDyO experiment location is just north of the SB Channel shipping lanes (light purple arrows) and well east of Plumes and Blooms Station #4 and of the NDBC Buoy #46053.

During the day, KM was located at 34 13.3N, 119 37.7W (173 m depth) or 1 nt mi north of FLIP at 34 12.312N, 119 34.715W .

R/V Kilo Moana collected data from September 9 ?25, 2009 and R/P FLIP collected data from September 7-28, 2009. Event logs for each platform are available from Tommy and Luc, respectively.

SBC Winds and Waves SB Wind Probability SB Winds
(Left:) Hourly SBC wind speeds (September-November) are on average 5 m s-1 (minimum ~0.5 m s-1; maximum ~12 m s-1) and wave heights are within 0.5 - 2.5 m. (Center:) The cumulative probability plots of winds for 2005 show that there is a 50% chance of 4 m s-1 winds in the SBC. Data are from NDBC buoy #46053. (Right:) Wind speed distribution (#53) from Edwin Beckenbach’s thesis.

SBC surface slicks:
Surface slicks are generally not an issue >4-5 miles offshore. The optimal location for avoiding slicks is near the NOAA buoy (NDBC #46053), which is in about 417 m of relatively optically clear water (in late-summer).
