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.
