Summary: Collected met data and uploaded two new programs to fix minor bugs, moved the well sensor higher to avoid out of range values.

Rush Ranch
2025-05-23

I arrived at the tower at about 9:30 PDT. I walked out to the site. It was sunny with a cool breeze. The grass lands are mostly brown but the marsh is green except where the pepper weed is in full bloom of white flowers. The NERRS folks have cut the grass inside their fence. I mashed down the weeds in front of our solar panels. Patty's crew was here yesterday but didn't have a working USB to serial adapter to talk to the data loggers.

At the main tower I downloaded the met data and then uploaded a new program that changes the air pressure output to the higher precision IEEE4 format.

I walked out to the annex tower. There I downloaded the met data and then uploaded a new program that adds RH to the output table. Patty's crew had made some measurements of the well sensor location yesterday but the problem is that it doesn't have enough range to get high tide. This morning tide was pretty low (no water in the ditch) and it was already reading 2628 mV - about half of its range (37.2cm). I moved it up until it read 1335mV (7.6cm). I think 1000mv = 0ft and 5000mV = 3ft (91.44cm).

However, looking at the well data now, I'm not sure what it is doing. It's been trending lower without any sort of tidal pattern that I can see.

There were some ants in the annex data logger box. I think they were coming up one of the soil sensor conduits. I pulled two loose and stuffed some mud in them before reconnecting. I swept as many ants out of the box as I could. It needs some moth balls next time.

I left the site about 10:00 PDT
