Temperature data recorded using HOBO Pendant MX2201 loggers deployed at 14 sites in Tomales Bay and Bodega Harbor during August 2019

Abstract:

To record water temperature, we deployed HOBO Pendant MX2201 loggers (fastened to PVC pipe) in the area from the 14 sites in Tomales and Bodega Harbors from which we collected genetic samples. The pipe was driven into the sediment until the logger was approximately <15 centimeters (cm) above the sediment surface, positioned to rarely be emersed except during low spring tides. We recorded water temperature at 15-minute intervals during a two-week period at all sites from 16 August to 29 August in 2019.

Methods & Sampling

To record water temperature, we deployed HOBO Pendant MX2201 loggers (fastened to PVC pipe) in the area at each of the sites from which we collected genetic samples. The pipe was driven into the sediment until the logger was approximately <15 centimeters above the sediment surface, positioned to rarely be emersed except during low spring tides. We recorded water temperature at 15-minute intervals during a two-week period at all sites from 16 August to 29 August in 2019.

BCO-DMO Processing

- Added column "Site" to the "Metadata" sheet of original file "temperature_data_shared_dates.xlsx" to create a site list.
- Imported both sheets of original file "temperature_data_shared_dates.xlsx" into the BCO-DMO system.
- Used 'Unpivot' processor to create a column for Site name.
- Joined the site latitude and longitude from the site list to the primary data file.
- Corrected typo in one site name (changed "Beachg" to "Beach" in "Doran Beach").
- Converted the local date/time field to ISO8601 format.
- Created a second column for date/time in UTC time zone.
- Sorted data by site name, then date/time.
- Saved the final file as "924671_v1_tomales_bodega_temp.csv".

Supplied Description:

Instrument Type

Generic Name: Onset HOBO Pendant MX2201 temperature logger

Acronym: Onset HOBO Pendant MX2201

Generic Description:

The Onset HOBO MX2201 is an in-situ instrument for wet or underwater applications. It supports soil temperature, temperature, and water temperature. A one-channel logger that records up to approximately 96,000 measurements or internal logger events with 8K bytes memory. It has a polypropylene housing case. Uses Bluetooth to transmit data. Can be used with a solar radiation shield. Measurement range: -20 deg C to 70 deg C. Accuracy: +/- 0.50 deg C from 0 deg C to 50 deg C. Water depth rating: 30.5 m
