Summary: Installed Robert's three temperature profiles, floating chamber profiles, fiddled with more EXO settings
2024-09-19 Joe arrived around 9:00 PST and Robert, Kuno, and I arrived shortly after. It was mild, sunny, and breezy. It has been relatively cool this week (highs in the 80's), but we'll have a short heat wave this weekend and early next week (highs in the high 90's). Today Robert and Kuno are installing 3 soil temperature profiles in the wetland and taking floating chamber measurements for CO2, CH4, and N2O. Robert made the thermocouples and Joe had prepped most of the equipment in the lab. The staff gauge read 40cm at 10:30 PST. Joe measured the surface water conductivity off of the boardwalk. I did not download any data at the tower but I checked that the mux was clocking and the 7550 USB LED was blinking appropriately. Surface, 535uS, 19.9C
Northside station (NS, Robert_IRT_A) Southside station (SS, Robert_IRT_C) Upland station (UL, Robert_IRT_B) I went to the channel to grab the channel miniDOT sn 180871 for Kuno and Robert to use at their temperature profiles. I pushed the ADCP and EXO back under the water. Back at the tower, I downloaded data from both this miniDOT and the Mayberry miniDOT and changed their desiccants. I attempted to sync the miniDOT clocks with miniDOTControl.jar (v1.06). One of the miniDOTs was 10 minutes behind and one of the miniDOT was 20 minutes ahead. I used my phone’s mobile hotspot to provide internet to the laptop, and I temporarily turned off the firewall, but miniDOTControl was not able to access an online time server to set the time. I called PME and they told me to update my miniDOTControl.jar to the latest version, v1.08. I downloaded this new version and was able to set the clocks without any problem. I changed the sampling interval from 10min to 5min per Kuno’s request. Next time I download miniDOTs at the other sites, I can sync their clocks with the latest miniDOTControl.jar. Robert, Kuno, and Joe waded into the wetland to install the three sets of sensors. Each set has an enclosure with a CR10X, lithium power pack, and solar panel on a steel post. The thermocouple profile is installed about a meter (?) away and an IRT is mounted to the top of the post, pointing toward the bottom of the thermocouple rod. Two sites also have a miniDOT zip-tied to the post, under the water and just above the soil surface. About 30 minutes (?) after installation, Robert and Kuno went back to the three sites to take chamber samples. CO2, CH4, and N2O were measured using opaque chambers near each monitoring location, with three replicates per site, with a low tide event from 11:45 to 12:30 PST. Next time, I should bring spare power packs to swap. I also need to set up the three CR10Xs on my field laptop. The CR10X programs are named with the IRT sn, because each IRT has different coefficients. Joe and I went to the channel around 10:40 PST to continue troubleshooting the EXO. Joe pulled the EXO and ADCP up again and cleared off the weeds that it pulled up. I can't remember if I downloaded the ADCP data or not. This time, there was 30min data on the CR6, yay! I power cycled the EXO to activate its Bluetooth. I connected to the EXO via Bluetooth and downloaded the EXO 5min data since 2024-08-29. The CR6 is still only recording 9 of the expected 11 columns even though we confirmed 11 columns of data were coming in when we talk to the EXO through the CR6's Terminal Emulator. We made some more changes the CR6 program: Joe and I stopped back at the tower to check in on Kuno and Robert and left around 11:15 PST. |
