SBC LTER: Reef: Seasonal Kelp Forest Community Dynamics: Invertebrate and algal density

These data describe the abundance of common reef associated
species of macro invertebrates and macroalgae within permanent
plots of SBCLTER's seasonal kelp forest monitoring program to
track long-term patterns in species abundance and diversity. The
number of individuals of approximately 50 taxa were recorded by
divers along 40 m transects within each plot. Small species of
macroalgae and macinvertebrates were counted within six permanent
1 m2 quadrats positioned uniformly
along the 40 m transect, while larger species were counted within
four contiguous 20 m2 sub-sections of
each 40 m x 2 m transect. Also included at the quadrat scale are
estimates of an average size-related measurement of each species,
which was developed specifically for each species for the purpose
of estimating its biomass. The experiment was initiated in 2008 at
five reef sites along the mainland coast of the Santa Barbara
Channel.

本数据集记录了圣巴巴拉海岸长期生态研究站（SBCLTER）季节性海带林监测项目永久样地内，常见礁栖大型无脊椎动物与大型藻类的丰度情况，旨在追踪物种丰度与多样性的长期变化模式。研究人员通过潜水调查，在每个样地的40米样带上记录了约50个分类群的个体数量。针对大型藻类与小型大型无脊椎动物，调查人员在沿40米样带均匀布设的6个永久1平方米样方中完成计数；而大型物种则在每个40米×2米样带的4个连续20平方米子区域内进行统计。在样方尺度的调查数据中，还包含针对各物种专属制定的平均体型相关测量值，用于估算该物种的生物量。本监测项目于2008年在圣巴巴拉海峡大陆沿岸的5个礁场站点正式启动。
