Protocols and/or Procedures
Description:

Submersible temperature loggers (Tidbit, Onset Computer Corporation, Bourne MA) were used to measure bottom temperature at nine coastal reef and two island sites in the Santa Barbara Channel, CA. These temperature loggers measure temperature in water within a range of -20°C to 30°C, and accuracy of ± 0.20 °C at 25°C.

Two temperature loggers were deployed at each site at a depth of approximately 7 m (MLLW), and fastened to permanent rebar stakes on the seafloor with two cable ties. Each logger was programmed to record ambient temperature every 30 minutes. The programming of the two Loggers at a site were offset by 15 minutes so that the final record shows a temperature measurement every 15 minutes. Temperature loggers were retrieved and replaced bi-annually with a new logger, typically in the early summer (June-July) and in early winter (January-March).
