Biological sulfate reduction rate measurements in cores from Peru continental margin of RV SONNE cruise SO147

his dataset provides sulfate reduction rate data, measured with radiotracer incubations. Samples originate from the Peru continental margin, taken during SONNE Cruise SO147 in May-July 2000. Sediment samples from the uppermost ca. 20 cm were taken with a Multicorer (MUC), deeper samples down to ca. 4 m with a gravity corer (GC). Radiotracer incubations were carried out on board, incubation lasted 24 hrs at approximate in-situ temperature (4°-14°C). After termination of the incubations, the samples were sent back to MPI Bremen for quantification of SRR, using the single-step hot chromium distillation of Fossing & Jørgensen (1989, doi:10.1007/BF00002889)

该数据集提供通过放射性示踪剂培养法测得的硫酸盐还原速率（Sulfate Reduction Rate, SRR）数据。样本采集自秘鲁大陆边缘，于2000年5月至7月的SONNE航次SO147期间获取。最上层约20厘米的沉积物样本采用多管取样器（Multicorer, MUC）采集，深度可达约4米的深层样本则使用重力取样器（Gravity Corer, GC）采集。放射性示踪剂培养实验在船上进行，培养时长为24小时，温度接近原位温度（4°C至14°C）。培养结束后，样本被送回不来梅马克斯·普朗克研究所（MPI Bremen），采用Fossing与Jørgensen（1989，doi:10.1007/BF00002889）提出的单步热铬蒸馏法对SRR进行定量分析。
