Santa Barbara Channel Marine BON: Integrated quad and swath cover

The Santa Barbara Channel MBON tracks long-term patterns in species abundance and diversity. This dataset contains counts of algae and invertebrates (both sessile and mobile) by integrating data from four contributing projects working in the kelp forests of the Santa Barbara Channel, USA. This dataset includes three entities, two data tables and R code. The main data table number of organisms and the area over which that number was counted for calculation of areal abundance. Data were collected by human observation (divers using SCUBA) during regular surveys. The column labeled “count” records the number of organisms found at a given timestamp. The algae and invertebrate counts record the number of taxa found in each plot, including quad (small square plots such as 1 or 2 m 2 ) and swath (large linear plots such as 60 m 2 ). See Methods for information on integration and data processing. A second data table contains place names and geolocation for sampling sites. Information is sufficient for the calculation of density, which is left to the user. Sample R-code is included (third entity) to illustrate generation of a basic table of areal density by taxa and sampling site. See Methods for information on integration and data processing The four contributing projects are two research projects: the Santa Barbara Coastal LTER (SBC LTER) and the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO), and the kelp forest monitoring program of the Santa Barbara Channel National Park, and the San Nicolas Island monitoring program supported by USGS. Together, these projects have recorded data for more than 200 species at approximately 100 sites on both the mainland coast and on the Santa Barbara Channel Islands. Sampling began in 1982 and is ongoing.圣巴巴拉海峡海洋生物多样性观测网络（Santa Barbara Channel MBON）长期追踪物种丰度与多样性的动态变化模式。本数据集整合了美国圣巴巴拉海峡海带林范围内4个合作项目的观测数据，涵盖藻类与无脊椎动物（包括固着型和移动型类群）的计数信息。 本数据集包含三类数据实体：两张数据表与R语言代码。主数据表记录了生物体计数数量以及用于计算单位面积丰度的调查样方面积。数据通过人工观测（使用自给式水下呼吸器（SCUBA）的潜水员）在常规调查中采集。标注为"count"的列记录了特定时间戳下观测到的生物体数量。藻类与无脊椎动物的计数项记录了每个样地内发现的类群数量，样地类型包括样方（quad，小型方形样地，如1或2平方米）和样带（swath，大型线性样地，如60平方米）。有关数据整合与处理流程的详细信息，请参阅方法部分。 第二张数据表包含采样点位的地名与地理坐标信息。数据集提供的信息足够开展密度计算，具体计算工作由使用者自行完成。第三类实体为示例R代码，用于演示如何生成按类群与采样点位分组的单位面积丰度基础数据表。有关数据整合与处理的详细信息，请参阅方法部分。 参与本数据集共建的4个项目包括两项研究计划：圣巴巴拉海岸长期生态研究项目（Santa Barbara Coastal LTER, SBC LTER）与沿岸海洋跨学科研究伙伴关系（Partnership for Interdisciplinary Studies of Coastal Oceans, PISCO），以及圣巴巴拉海峡国家公园海带林监测项目，还有由美国地质调查局（United States Geological Survey, USGS）资助的圣尼古拉斯岛监测项目。上述项目累计在大陆海岸与圣巴巴拉海峡群岛的约100个采样点位记录了200余个物种的相关数据。该调查工作始于1982年，目前仍在持续进行中。
