Plans

 S. California network deployment

 Chris still pinging on them for:

  • site visit
  • Depth, site, boat information
  • pier set-up

 Methane seeps in July

 --Going to the NE Santa Monica mound.  807m ~10-15m above seafloor.  100m across, 50m wide on top.  Currents are 10cm/sec on top of mound.

5.25C

Must pick-up McStar sometime during cruise.

Also will have 4 gulper samplers--2 on swing arm, 2 on porch.

Much discussion on hydrate spontaneously forming and how it may impact DWSM.

 Actions:

  • Can we mimic hydrate formation in lab?  unlikely.
  • What are our contingencies if we form  hydrate plug?  Exhaust the intake tube from the back side?
  • We could send a sample system down in March and see if you get hydrate formation.   

Lab Stuff

 Code:

  • Gordon/Betty running the same firmware/software
  • NEO -- super old stuff
  • Bruce/Mack--running older stuff, but they are even different from each other (although that diff is small; could be just in the WCR protocol script)
  • Moe--unknown what it has, as code has not been checked back into CVS in a long time

Plan:

Roll Bruce back to Oct, 2008 code and recreate a good DA run.

Push Mack forward so it's running Gordon/Betty code and see if that fixes sign inversion error.

Upgrade firmware on Moe to the latest.

Cheri will be helping with all this.
