  • Check CTD

CTD sensor is above water table so showing no data (conductivity and salinity reading 0), we measured the water level is 3cm high from the bottom of CTD.

  • The fan inside HMP stop working again
  • We cannot connect to the datalogger through ethernet, we connect from the router, but the download is super slow. If we cannot connect manually, check wireguard and deactive it.
  • Next time bring a spouge to clean the sticked bird pop
  • No standing water in the field, it looks dry (yellow) compare to field nearby and full of weeds.
