there are over 35 m of turbidites in this image. the upper most dark
horizontal line is the surface return (the contrast between sediment
and water). then the brighter parts (white) are sandy and the darker
parts are muddy (generally)... i counted at least 18 turbidites in
this sequence. this would be a spectacular place to collect a deep
core to investigate earthquake history. i now count more than 18. you
can read the lat/long in red, if you want to search for this location.
the amplitude envelope is in green on the right (for the current ping,
which is not representative of the turbidites seen in the center of
the image).
the other shot is from the bow of the thompson. i risked my life to
take this shot (not really, although i could have lost my balance and
fell over the edge).

Jason, i wish i understood more of what you're doing - it is very facisinating...(sp)? I love the study earthquakes and wish i had the nerves to study but I just dont. I guess I just have to take your reports and try to understand - thanks for studing for and then reporting!! Do you do this often? Carrie
i am on a cruise like this about once every 2 years so far. hope to keep this frequency up, but i will soon need to write my own proposals to do this work... jp
