These data describe losses of giant kelp (Macrocystis
pyrifera) blade tissue observed in the Santa Barbara
Channel (Isla Vista Reef) during the summer of 2012. Data are
contained in two tables: 1) a time series of measured change in blade
area over time at different depths and locations in the kelp forest,
2) modeled estimates of partial blade losses specific to blades on
subsurface fronds and blades in the water column and canopy sections
of surface reaching fronds.
