Marking core

Here are the Duke guys (sci1, Trevor, and Andy) marking core -- a GGC (giant gravity core, if you remember our last post) to be precise:
Don't they look like they know what they are doing? Here are a couple of questions: Is section #1 on the bottom or on the top? Which of the 150 cm sections should be marked 0-150? Which one of theses guys should we ask?!

Okay, you guessed it, we've had some core labeling issues in the last 24 hours. Yes, I've made a mistake or two myself. But, it became very funny last night and this morning -- at about the time we were all pretty exhausted. Why were we exhausted?

Perhaps it had something to do with this POD (plan of the "day"):
We're on deployment 28 right now. So, as crazy as it looks, it (or at least some close variation on this plan) IS possible . . .

By the way, for you guys who may be wondering what the mud in this part of the world looks like, here is a photo of the top portion of a GGC we took yesterday:
We're not splitting most of the cores on board ship, but we couldn't resist a peek.

With most of the cores, we simply mark them, cut them, and log them with the Geotek logger. Here's a portion of last night's pile of to-be-logged cores (and Gary drilling gas-release holes in cores -- a must do for these sediments):


Not bad for a day's coring!

  1. Impressive.
    Does drilling the cores to release gas allow oxygen to transform the chemistry of what you sample?
    Simply amazing, Dad says.
