SONGS Mitigation Monitoring: Experimental Reef Survey - Benthic Algae, Invertebrate, and Substrate Cover

These data describe annual estimates of the percent cover of benthic macroalgae, sessile macroinvertebrates, and substrate types 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). Data were collected from 2000 to 2004 as part of the experimental phase of the San Onofre Nuclear Generating Station (SONGS) kelp reef mitigation program. In the summer of each year, divers identified and recorded species of algae and sessile macroinvertebrates, and substrate types under twenty uniformly placed points within 1 m2 quadrats that were uniformly distributed along fixed transects at each reef.本数据集记录了三处鱼礁的底栖大型藻类（benthic macroalgae）、固着大型无脊椎动物（sessile macroinvertebrates）与底质类型（substrate types）的百分比覆盖年度估算值，其中一处为位于加利福尼亚州奥兰治县的惠勒北礁（Wheeler North Reef）人工鱼礁（artificial reef），另外两处为自然对照礁（natural reference reefs），分别是奥兰治县圣马特奥海带礁（San Mateo Kelp）与圣迭戈县巴恩海带礁（Barn Kelp）。该数据集的采集时段为2000年至2004年，属于圣奥诺弗雷核电站（San Onofre Nuclear Generating Station，简称SONGS）海带鱼礁生态缓解项目的实验阶段研究内容。每年夏季，潜水员会在各鱼礁沿固定样带（fixed transects）均匀布设的1平方米样方（quadrats）内，选取20个均匀布置的测点，对藻类、固着大型无脊椎动物物种及底质类型进行鉴定与记录。
