Servicing trips
Retrieve sonde and download data
If you are servicing any bridge site, the first thing to do when arriving is to contact
the U.S. Coast Guard and California Highway Patrol:
U.S. Coast Guard: 415-399-3451
California Highway Patrol: 510-286-6920
Inform them of your affiliation, your purpose for being on site, the kind of craft you are in
and how long you anticipate being on site.
Retrieve sondes:
● For Alviso Slough, all servicing occurs on the boat.
○ The instrument package is pulled from the bottom using an electric winch
(first pull up the weights, then the package).
● For bridge sites, servicing occurs from the bridge platform.
○ Unload all needed equipment from the boat (using a haul line if tide is
low)
○ Using the deployment line (not the communication cable), pull the
instruments up out of the water (to within comfortable reach), removing
the black clips as you go, and secure with the extra line on the davet.
○ If there has been a significant amount of fouling, the instrument carriage
may be heavy and it would be helpful to scrape off the fouling as it pulled
up.
○ Remove the bolt at the top of the carriage, remove the redundant line and
communications cable, and extract the EXO2 from the carriage.
Download data:
● Start KOR-EXO.
● Connect the EXO2 to the computer using the USB adaptor (KOR-EXO can be
picky about starting the software before connecting).
● Navigate to the Connections menu select “Re-scan” and select “EXO USB
Adaptor #xxxxx” from the list and select“Connect”
● Navigate to the Deploy menu and select “Stop Deployment”
● Make sure the KOR-EXO is pointing to the correct folder on the computer hard
drive. Navigate to the Data menu, select “Settings” and edit the “Default File
Location” to your preference. Select “Apply”
● Select “Transfer” (within the Data menu), select the most recent file from the list
and hit “Selected”. It will download as a .bin file
● After the data downloads, visualize it by selecting “View/Export” from within the
Data menu and pointing KOR-EXO to the file you just downloaded. You can view
each timepoint in a table, a graph with KOR-EXO or you can export to Excel (will
create a .xlsx file).
