These data summarize depth information (mean, standard deviation and coefficient of variation) for all of the transects surveyed as part of the SBC LTER Long Term Kelp Removal Experiment. All data are expressed in meters, referenced to mean lower low water (MLLW). Each value is the result of 160 observations, four at each meter (n=160). The sampling locations in this dataset are 40 meter transects at four reef sites along the mainland coast of the Santa Barbara Channel, California, USA. These data were recorded in 2010.
