Email 1: Station Maintenance for Itkillik River Crew 5/9/2011 @ 5:14 PM

Itkillik River:
I have a case w/ 3 HOBO PTs for the Itkillik River for upstream and
downstream slope.  Two of them are set to record 15 minute intervals
starting 5/13/11 at 5:00pm.  One is a spare and has not been launched,
and can be used if all else fails.  There is also the correct
launch/reader in the case this time.

You will also have to install 2 SDI12 PTs because the current ones are
locked in ice.  1 should be 15psig (older unit) and 1 should be a new
5 psig sensor.

You will also have to replace the station barometric pressure ASAP
when you get to the site, because I couldn't make anything of the old
data, it seems to be bad.  Barometric pressure is needed for
correction with the HOBO sensors.

Please download camera images and any historic camera images saved to
the camera.


Other station maintenance includes:
Upper May Creek: Tipping bucket / windshield repair, download camera images
Itikmalakpak:  Tipping bucket / windshield repair, download camera images

And as always, if the fence needs repair, please try and fix it up.

Email 2: to do: PTs5/9/2011 @ 5:05 PM

Gather 2 PTs from downstairs in 106 to go to Itkillik River.  Get 2
with the shortest cable lengths because the station is close to the
river and so we shouldn't need the 250 ft cable length (unless that is
all that is available than that is all we have).  Ask Rob which one
you can take and then obtain the calibration information from Rob for
that particular serial number.  Make sure they are labeled at the
wiring end and have a dessicant pack.    Make sure you obtain a
working sensor because apparently 1-2 were not working.

Then, in my office there is a box from instruments northwest, Inc.
Open the box.  Put a label on at the wiring end that says the Serial
Number, 5 PSIG (verify from calibration sheet), the cable length (all
should be 250 ft), and the SDI12 Address which is located on the
calibration sheet.  Include one of the new 5 PSIG in the Itkillik
River package.

We will have 3 PTs for the Itkillik River, 1 5-PSIG, 1 15-PSIG, and 1
15 PSIG backup.

Then we will have to make sure all the PTs have conduit for
protection, so if the old ones don't come see me.  We will have grab
some conduit / pipe / reducers etc. for the new 5 psi PT.
