3.5 kHz logging example

here is an example of the 3.5 kHz CHIRP logging that we are doing here
offshore WA.

i mentioned this log in a previous post. depth is marked on the right.
i have labeled two units, a lower more sandy unit i am interpreting as
tubidites. the upper unit is either a series of muddy turbidites or
simply just mud. i suspect there are turbidites here, as i see some
faint reflections (difficult to see in this image).

this was taken in an arm of the Juan de Fuca Channel at approximately
N 47 24.5424 W 125 23.5226. the channel is colored blue in the next
image i will post.
