Ops 6 Apr

A quiet day.  Took truck to Jiffy Lube, then hit s7 for the last soil core of round 1.

At base, finally started the AC by turning on the circuit breaker.  Not sure when it was turned off.

Also tried to debug one of SHT.  Even removing the TPS76033, it require excessive current at 3.3V (it took more than 60mA and pulled the power supply voltage down).  That SHT (61, I think) appears to be dead.

Tried to fill in the remaining cores into Google forms, but ended up with a duplicate entry for s17.  Haven't figured out how to remove it.

Isabel vacuumed the base!  Yay, Isabel!

Victron.s10

Had to bring it back with ddn/dup again.  Curious.

Ops 5 Apr

Took the day off to Santa Cruz (but then noted a weather station there – station SCZ), with rough seas (small craft advisory).

Inspecting qctables at the beginning and end of the day showed no new issues to me.


Ops 4 Apr

Start of IOP-1, so not expecting to do much ISFS work:

s9: (just changing the manfrotto screw anchor to a T stake to better withstand expected high winds)

  • screw anchor seemed secure, but pulled out easily after one turn, so a good idea to have switched
  • found that I hadn't tightened the TRH setscrews, so TRH was dangling by its cable!  Bad Steve.  Now secure.

iss2: Mary Cal did the 1pm launch!

s13: took soil core

Also attended 2 meetings and worked on debugging the faulty SHTs – found at least one blown voltage regulator.

Hopefully, taking tomorrow off for an Island day trip, though not sure if it will go if the sundowner winds are correctly forecast!



Ops 3 Apr

All pretty quiet.

Only thing I noticed in the data was that the qsoil at s5 has been giving negative values, which (I think?) is bad. That's Exxon, so I don't think we could have gotten in today.

Qsoil.s8 back

Just needed an "si" command sent to the mote.  Tried this yesterday, but the connection was too sluggish.

Ott.s16 reconfigured

The output message from this Ott didn't include the histogram.  I've just followed the steps in this link (ISFS/SensorInformation/OTTParsivel#2.USAGE) to set the message.  Since the serial number is reported as XXXXXXX, I'm assuming that it is serial number 410948 (haven't found the record of serial numbers in our wiki(?)) and followed the steps also described by the link to cheat.  It now seems to be working as desired.

P.S. Found Tony's serial numbers in AssetPanda, showing that this sensor was 450620, so I've just changed this.  No change of the actual sensor.


Ops 2 Apr

Low marine stratus, became thick fog as we went in the mountains.

Not much to do:

s10: (was sunny on top)

  • change out Qsoil since old one had high values and spikes after the last storm
  • clean NR01 at 11:32
  • check data

s9: just drove up to – couldn't see site from parking area in the fog!  Everything looked okay, and fan was running

s4:

  • took soil core
  • taped one connector on cr mote, since didn't have cap with us
  • check data

s3:

  • took core

s1:

  • took core
  • check data

Two more sites to go in the first round of soil cores...

Ops Day 1! (1 Apr)

Since we still had the UTV rented, went to s16 (the first time for me) with Bill (also a rare event!). Parked at the upper Oso campground, just shy of the gate.  Returned to find a notice to pay a $10 fee to park there (despite our Gov't plates and the use permit on the dash).

s16:

  • Took care of punch list items, except for the Y cable that I forgot at the bottom of the mountain.
  • Took soil core
  • Did nothing to the TRH (should have at least checked that the cable was seated well, but didn't)
  • Found that the Ott is misconfigured – need to try to do this remotely.
  • Tilted down the mast to clean the EC150, but didn't help the data much.  I suspect the desiccant bottles may need to be changed, but that would invalidate the data for a day (and require a calibration check?)
  • While mast was down, move the QDP to the other side of the sonic (away from the EC150).
  • Need to add to standard visit check: reseat cables (at DSM); move wetness sensor flat (done today)
  • Also noted that one bolt holding the capture plate had thread damage.  Replaced with another slightly-less-damaged bolt, but should replace with a new one.
  • Finally, need to add more site direction documentation – Google maps was somewhat off.
