Records of moored SeaFET pH, SeaBird CTD and oxygen at Anacapa, Santa Cruz and San Miguel Islands, California from 2012-2015

Data are pH (total scale, SeaFET), salinity, conductivity, temperature, depth (Seabird 37 CTD) and Oxygen (MicroCAT C-T-ODO) from instruments moored at three sites along the north shores of the northern Santa Barbara Channel Islands, California, USA. At Anacapa Island (ALC), in a marine reserve with kelp forest habitat; at Santa Cruz Island (PRZ), surrounded by a large shallow eelgrass bed (Zostera pacifica); and at San Miguel Island (SMN), in open water over a sandy bottom. pH sensors were deployed at all three sites in 2012, with CTD and Oxyten senosrs added to moorings at ALC and PRZ in May 2013. Benchmark samples for SeaFET sensors calibration were collected 1 to 8 times during each 2 - 3 month deployment via SCUBA, free diving or from a pier with a GO-FLOW (General Oceanics) bottle (see methods). Oxygen data were validated by Winkler titations, with concentrations reported in various units and as saturation. Data are presented in: Kapsenberg, L. and G. E. Hofmann 2016. Ocean pH time-series and drivers of variability along the northern Channel Islands, California, USA. Limnology and Oceanography. 61: 953-968. DOI: 101002/lno.10264.

本数据集涵盖美国加利福尼亚州圣巴巴拉海峡北部岛屿北岸三个锚定观测站点的原位观测数据，观测指标包括pH（总尺度，SeaFET传感器）、盐度、电导率、温度、深度（Seabird 37型温盐深仪（CTD））以及溶解氧（MicroCAT C-T-ODO传感器）。三个观测站点分别为：阿纳卡帕岛（ALC），地处带有海带森林生境的海洋保护区内；圣克鲁斯岛（PRZ），周边环绕大片浅海太平洋鳗草（Zostera pacifica）床；圣米格尔岛（SMN），位于沙质底质的开阔水域中。2012年，三个站点均部署了pH传感器；2013年5月，研究人员在ALC与PRZ站点的锚系观测装置中新增了温盐深仪与溶解氧传感器。SeaFET传感器的校准基准样品在每2~3个月的部署周期内，通过水肺潜水（SCUBA）、自由潜水或使用GO-FLOW型采水器（General Oceanics公司生产）在码头采集，单次部署周期内采样1~8次，详见研究方法。溶解氧数据通过温克勒滴定法（Winkler titations）进行了有效性验证，浓度以多种单位及饱和度两种形式报告。本数据集源自Kapsenberg L与Hofmann GE于2016年发表的研究论文《美国加利福尼亚州海峡群岛北部海域的海洋pH时间序列与变异性驱动因子》，刊载于《Limnology and Oceanography》，第61卷，第953-968页，DOI: 10.1002/lno.10264。
