15,000 psi

We are coring and the bottom is stiff. Instead of using the cable to pull the core out, they are putting a certian amount of tension on the cable and the slight rocking of the ship tugs on it...it goes from 5000 psi (units?) to 13,000 depending on the roll. They got the previous one out of the bottom but there was only one meter of core. The added mass to the corer and last time I checked it was still stuck. We are after the mid Pleistocene climate transition, and this core will likele be from the early part. The sedimentologists and the paleo people would like 3 m of core in order to do their magic.

I'm having a really tough time with the seismic interpretation up to this area. I was originally off by 250%. A little different precision than the 63 cm overlap on one core sited 75 m laterally from the other one, in 120 m of water depth.

Food has been really good, especially the last 2 days. Hmm...belly wants snack.
