These data describe the abundance of macroalgal detritus (grams wet
mass m-2) at SBC LTER long-term kelp
removal experiment sites. Detritus is collected in six permanent 1
m2quadrats positioned uniformly along 40 m
transects in each sampling plot. Sample collections are brought back
to the laboratory, identified to species and weighed wet. Detritus is
not collected at continuous removal transects.
The kelp removal experiment was initiated in 2008 at four reef sites
along the mainland coast of the Santa Barbara Channel. The following
three giant kelp manipulations are maintained in sampling plots at
- Control: Macrocystis pyriferais left intact in
a 2000 m2plot.
- Annual removal: Macrocystis pyriferais removed
from an adjacent 2000 m2plot once each
winter and allowed to re-colonize over the course of the year.
- Continuous removal: Macrocystis pyriferais
removed from a 200 m2area within the 2000
m2 plot on each sampling date.
