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

These data describe the density and size of a select group of about 50 species of benthic invertebrates and understory algae in fixed plots (either 1m x 1m or 20m x 1m) along permanent transects. These data are part of SBCLTER’s kelp forest monitoring program to track long-term patterns in species abundance and diversity of reef-associated organisms in the Santa Barbara Channel, California, USA. The sampling locations in this dataset are at nine reef sites along the mainland coast of the Santa Barbara Channel and at two sites on the north side of Santa Cruz Island. These sites reflect several oceanographic regimes in the channel and vary in distance from sources of terrestrial runoff. Sampling began in 2000, and these data are updated annually. The time period of data collection varied among the 11 kelp forest sites. Sampling at BULL, CARP, and NAPL began in 2000, sampling at the other 6 mainland sites (AHND, AQUE, IVEE, GOLB, ABUR, MOHK) began in 2001 (transects 3, 5, 6, 7, 8 at IVEE were added in 2011). Data collection at the two Santa Cruz Island sites (SCTW and SCDI) began in 2004. See Methods for more information. See Methods for more information.

本数据集记录了美国加利福尼亚州圣巴巴拉海峡沿岸永久样带上固定样方（规格为1m×1m或20m×1m）内约50种预选底栖无脊椎动物（benthic invertebrates）与下层藻类（understory algae）的密度与个体大小。本数据集隶属于SBCLTER的海带森林（kelp forest）监测项目，旨在追踪圣巴巴拉海峡内礁栖生物的物种丰度与多样性长期变化格局。本数据集的采样点位涵盖圣巴巴拉海峡大陆沿岸的9个珊瑚礁样点，以及圣克鲁斯岛北侧的2个样点。这些样点覆盖了海峡内多种海洋水文环境，且与陆地径流源的距离各不相同。采样工作始于2000年，且数据集每年更新一次。11个海带森林样点的采样起始时间存在差异：其中BULL、CARP与NAPL样点的采样始于2000年；其余6个大陆沿岸样点（AHND、AQUE、IVEE、GOLB、ABUR、MOHK）的采样始于2001年，IVEE样点的3、5、6、7、8号样带于2011年新增；圣克鲁斯岛的2个样点（SCTW与SCDI）的采样始于2004年。详细信息请参见方法部分。详细信息请参见方法部分。
