Summary: Turkey vultures, Reinstalled calibrated EXO without auto brush

Hill Slough
2024-01-25

I arrived at about 9:15 PST. It was clear sunny and mild. The water was near low tide and the staff gauge read 3.64 at 9:25 PST. There were three turkey vultures guarding the entrance to the boardwalk – maybe not the best omen to begin the day. They moved off down the boardwalk as I approached.

This was a quick stop to reinstall the freshly calibrated EXO. The automated brush has be removed for repair. The blue tooth LED was lit and the red LED was blinking. When I first put it in it sank to the bottom to sit on the mud before I realized that the yellow chain would hold it higher than its cable. Being attached to the yellow chain kept the sensors out of the mud. Sensors installed:
sn 22C103416 EXO2
sn 22E106072 Turbidity
sn 22E100649 fDOM
sn 23D104030 Conductivity/Temperature
sn 22D102641 pH/ORP

I checked the other water sensors to make sure they were not in the mud.

I put the lubricant on the EXO connector pins and then accidently dropped the nearly empty tube into the water and watched it slowly float away with the tide.

I left at about 9:30
