UCSB SONGS Mitigation Monitoring: Reef Process Study - Density of Giant Kelp Recruits and Cover of Dead Holdfasts

These data describe annual estimates of the density of giant kelp recruits and the percent cover of dead giant kelp holdfasts from replicate quadrats at three subtidal reefs. Data collection occurred from 2000 -2023 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).

本数据集记录了3处潮下带礁体的重复样方中，巨藻（giant kelp）幼体密度与死亡巨藻固着器盖度百分比的年度估算值。数据采集于2000年至2023年，采集地点包括1个人工礁——加利福尼亚州奥兰治县的惠勒北礁（Wheeler North Reef），以及2处自然对照礁——加利福尼亚州奥兰治县的圣马特奥巨藻礁（San Mateo Kelp）与加利福尼亚州圣迭戈县的巴恩礁（Barn Kelp）。本数据集旨在评估惠勒北礁能否弥补圣奥诺弗雷核电站（San Onofre Nuclear Generating Station, SONGS）运行所导致的巨藻林生境及相关生物群落的损失。
