Dataset: Intertidal mooring temperature
Deployment: KH_intertidal_2008-2015

Temperature data were collected using Onset TidbiT v2 Water Temperature Data Logger - UTBI-001 (http://www.onsetcomp.com/products/data-loggers/utbi-001). Specifications reported by Onset for this product are as follows: temperature sensor accuracy: ± 0.2°C (from 0° to 50°C); resolution: 0.02°C (at 25°C); response time: 5 minutes in water to 90% and drift: 0.1°C per year; time accuracy: ± 1 minute per month (0° to 50°C). In some cases when the primary data logger at a site failed, temperature data from a HOBO Pendant® Temperature/Light Data Logger 64K - UA-002-64 (http://www.onsetcomp.com/products/data-loggers/ua-002-64) were substituted. Specifications reported by Onset for this product are as follows: temperature sensor accuracy: ± 0.53°C (from 0° to 50°C); resolution: 0.14°C (at 25°C); response time: 5 minutes in water to 90% and drift:< 0.1°C per year; time accuracy: ± 1 minute per month (at 25°C).

Temperature data loggers were installed in the mid-intertidal zone (~ 0– 0.3 m above MLLW) at sites in California, USA. The sensor was attached by plastic cable ties to the top of a small stainless steel cage that was affixed to the rock by stainless steel lag screws using plastic high tension anchors set into pre-drilled holes; the sensor itself was thus suspended just above the rock.
