UCSB SONGS Mitigation Monitoring: Reef Performance Standard - Benthic Algae and Macroinvertebrate Cover, Abundance, and Richness

These data describe annual estimates of the percent cover, abundance, and species richness (evaluated as species density) of benthic macroalgae and macroinvertebrates from replicate transects at three subtidal reefs.
Data collection began in 2009 at an artificial reef (Wheeler North Reef in Orange County, CA) and two natural reference reefs (San Mateo Kelp in Orange County, CA and Barn Kelp in San Diego County, CA) to evaluate the ability of Wheeler North Reef to compensate for losses of kelp forest habitat and associated biota caused by the operation of the San Onofre Nuclear Generating Station (SONGS).

本数据集收录了三处潮下带礁体重复样带中采集的底栖大型藻类（benthic macroalgae）与大型底栖无脊椎动物（macroinvertebrates）的盖度百分比、个体丰度，以及以物种密度表征的物种丰富度的年度估算值。
数据采集工作于2009年启动，采集点位包括一处人工礁——加利福尼亚州奥兰治县惠勒北礁（Wheeler North Reef），以及两处天然参照礁：加利福尼亚州奥兰治县圣马特奥巨藻礁（San Mateo Kelp）与加利福尼亚州圣迭戈县巴恩巨藻礁（Barn Kelp），旨在评估惠勒北礁能否补偿圣奥诺弗雷核电站（San Onofre Nuclear Generating Station, SONGS）运行所导致的巨藻林栖息地及相关生物群落损失。
