Gary and I went to the Marsh around 16:30 hoping to catch the low tide. Unfortunately
we were to early to go under the bridge so we had to go the long way. We did accomplish a number of tasks.
(1) remove NR01  for repair work, S15, (2) replace the TRH housing at S5 due to flaky I fan, and replace the
TRH at site 11. We were able to get under the bride coming back at about 18:30.
