White shark data now public (including Ano buoy)

[kalyp]

Hello,

For those of you who may be interested... Researchers have been tagging white sharks with acoustic tags and there are "listening" buoys around - Farallones, Tomales, Ano Nuevo. Everytime a tagged shark swims by the buoy (range about 200m), a hit is recorded.
You can see the data at http://gtopp.org/ (cf "White Shark Network Goes Live"). For Ano I believe that the sudden disappearance of all sharks in Feb is because the buoy stopped working at that time. Of course no hits doesn't mean no sharks, only no tagged sharks (assuming the buoy is working). Also if the tag is "heard" at Ano it means it is within a few hundred meters thus not at Waddell. So not directly useful for Waddell kiters but an indication of how many there might be at the time! (they're pretty seasonal, mostly offshore in spring/summer, around in fall/winter).
