  • These data describe the cover of bottom substrate types and the sand depth (if the point was covered by the sand) as determined by a uniform point contact method. The presence of 8 substrate types are recorded at 80 uniformly spaced points along permanent 40m x 2m transects. Percent cover of a given substrate on transect can be estimated from UPC observations as the fraction of total points at which that substrate was present x 100. The percent cover of substrate at a location cannot exceed 100%.

    The kelp removal experiment was initiated in 2008 at selected reef sites along the mainland coast of the Santa Barbara Channel. The following three giant kelp manipulations are maintained in sampling plots at each site:

    - Control: Macrocystis pyriferais left intact during the experiment.

    - Annual removal: Macrocystis pyriferais removed from an adjacent plot once each winter and allowed to re-colonize over the course of the year.

    - Continuous removal: Macrocystis pyriferais removed from the plot on each sampling date.

    The two tables in this data package include: 1) The percent cover of bottom substrate; and 2) the sand depth if the substrate is sand. See protocol for more information.
