54.2104 W 124 18.2018. the core we are collecting here may help us
further resolve the relations between CSZ and SAF tectonics.
we are just west of an unnamed fault that bounds the southwest
boundary of the Viscaino block. the fault offsets several submarine
canyons. the last potential core site was abandoned as it appeared to
lack a good stratigraphic record (too muddy). we think it is too muddy
as the fault that offset the cayon thusly shut off the sediment supply
here. so, i pointed out to chris that we could constrain the age of
this by coring there. if we can do this, we will be able to determine
a slip rate on this fault. there are currently no estimates of slip
for this fault as nobody has worked on it (it remains unnamed, but we
will name it; it's not my fault, the person it is named after must be
dead).
after this, we will transit further north on the abyssal plain,
downstream of submarine canyons draining the viscaino block. as i
mentioned in an earlier post, these canyons are not connected, in any
way, to sediment draining the shelf nor terrestrial drainages (rivers
or streams).
yet another beautiful day in paradise on this wonderful rust bucket
called the R/V Tommy G. Thompson. i slept a good 9.5 hours, but i am
still tired. still fighting a cold, but i am not getting worse.
finally the air conditioning got fixed. the last couple of days were
terribly hot and i kept falling asleep in the lab. i was really worn
out from the heat. in my berth, i was laying in bed with no sheets and
sweating. last night however i got to use my blanket. love it. i hope
to work on my GSA (geological society of america) meeting
presentations soon. i started one, but not the other.
swells have increased, as is my ginger caps consumption. i feel great!
peace out, Sunshine!
