Instrument: Onset TidbiT v2 Water Temperature Data Logger - UTBI-001
A temperature logger that measures temperatures over a wide temperature range. It is designed for outdoor and underwater environments and is waterproof to 300 m. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 or M-RSA Solar Radiation Shield). With an operational temperature range between -20 degrees Celsius and +70 degrees Celsius, the TidbiT v2 has an accuracy of +/-0.21 and a resolution of 0.02 degrees Celsius.
Temperatures of the eastern and western faces of each block were recorded at 2 min intervals by one Hobo Tidbit v. 2 datalogger (Onset Computer) per face, adjacent to barnacle prey.
