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SBCLTER（圣巴巴拉海岸长期生态研究项目）季节性海带林监测计划中，永久样地内常见珊瑚礁伴生大型无脊椎动物（macro invertebrates）与大型藻类（macroalgae）的丰度，旨在追踪物种丰度与多样性的长期变化模式。研究人员通过潜水员在每个样地的40米样带上，记录了约50个类群的个体数量。沿40米样带均匀布设的6个永久1平方米样方（quadrats）内，统计小型大型藻类与大型无脊椎动物的个体数；大型物种则在每个40m×2m样带的4个连续20平方米子区域内完成计数。在样方尺度的统计中，还包含了针对各物种专门开发的平均体型相关测量值，用于估算该物种的生物量。本监测工作于2008年在圣巴巴拉海峡大陆沿岸的5个珊瑚礁站点正式启动。
