Description

Temperature data from 4 depths at the study site in the giant kelp forest habitat of the Central California Coast. Temperature was recorded every 5 minutes from June 2010 to October 2012.

Acquisition Description

Onset Stowaway Tidbits (+/- 0.2C) were positioned at 0.5, 4.8, 8, and 13.5 m along a mooring line at the study site. The loggers were set to record temperature every 5 minutes and were swapped out approximately every 3 months by divers.

Processing Description

Data were downloaded in the lab and converted to tab delimited text files. Data were quality controlled and trimmed to fit accurate temperature recordings and cut to minimize the data gaps between collection and deployment of new loggers. After deployment the loggers took approximately 2 hours to equilibrate to ambient water temperature. Comparison between the temperature data on a logger just prior to collection and the temperature data at the time of deployment for a logger collected the following month were used to identify accurate data measurements and outliers were removed from the data set. Occasionally an entire record for a particular depth was lost due to instrument failure.

Files were named labeled with a letter indicating which depth in the water column they were collected (S=surface (0.5 m), T=top (4.8 m), M=Middle (8 m), B=bottom (13.5 m)). Dates in the file names indicate the dates of deployment to retrieving the tidbits.

Missing Dates:
Surface - June 2010 to September 2010
Top - July 2012 to September 2012
Mid - September 2011 to December 2011
