Machine Builds

•  Cores:  A big thanks to Cheri for all her hard work these last 4 weeks preparing and then leading the build effort while McLane was here.
  • On Gordon and Betty:
    • all mechanical systems built, wired, and plumbed
    • all, that is, except the hands
    • discovered discrepencies on both Prunella and El Camino orders; some issues are the drawings, some are their work
    • we will be using one old, one new harmonic drive for the hands
  • R-valves.  6 of 35 boards were bad.  Dick had these marked in the Project Library, but Cheri didn't know about that spreadsheet.
• HV pucks.  seems to be working well; got a nice array from 4L of fluid.  If it works well for invertebrates, we might modify some of our SH1 pucks to test before we place a new puck order.  Chris S. working on this.
• We need screens by end of April/May deployments.  Science will inventory rings and screens so we can place new order.
• WAG:  scope hardening of ESP to 200m = 1 year.
•  

MFB

• Mike has finished SPE heater modifications.  Only need PCR tubing to ship to McLane.

Software

•  dPress code ready for testing.  Wayne will load Monday AM
• Brent not started on DWSM yet.

Deep ESP

• ISUS
  • Luk says they have a 4km housing; just need a new probe--a PO away. 
  • We WILL NOT put ISUS on elevator in June
  • John Ryan is taking over ISUS work.  We may eventually want a TI housing.  Craig Okuda may havve one for us (or a design)

Sphere

• Spider construction.  All parts are machine shop.  Will be finished today.
• Frank F. will do welding week after next in the high-bay.  We'll have to get the sphere bottom out of its crate for that.

Elevator

•  Still 3 weeks out.  They had to send it out to be heat treated as their facility wasn't big enough.
• Modem.  Because of where Clague will want to go while at Axial, we will probably NOT be within 2km of our drop site (which is required w/ a 60degree modem).  Doug thinks we should change to low frequency modem--still working on power calculations, but seems we will buy a Low Freq omnidirectional model.
• Will purchase for the Flyer June deployment--must order in the next 2 weeks.
• Foam.  being cut.  ready in 2 weeks $1400.

DWSM

• Sample bags and switches are made
• We may not have stirrer motors in both bags by April.
• Bags are being assembled
• Oil & water not being pushed yet-still having Jose make interface boards-should be finished early next week.

Other Items:

•  Van:  Doug has provided sketch of outlets (16) and lights to Greg Voogd
  • we will push ESP to front of van and build a false wall so only front needs cooling
  • Idea to put foldable desks (like Murphy tables)
  • Need to check with Chris Grech about powering the van on UNOLS ships--what do we need?
  • Greg will level the van next week.
  • We need to figure out ventilation issues (i.e., false doors, screen doors, louvers, etc).  Check w/ Ussler's van--how does he ventilate?
• Shallow ESP lids --need modification.  Original P1 connector is a threaded thing that is breaking.  Needs re-machining.  Scott will handle.
• Potential Institute-wide chemical inspection--should have MSDS for all chemicals in Bldg A & B labs.
