Bottom Temperature and Dissolved Oxygen Saturation in Sechura Bay

This dataset contains oceanographic records of bottom temperature (°C) and dissolved oxygen saturation (%) from Argopecten purpuratus (Peruvian scallop) bottom-culture, in the Constante production zone, Sechura Bay (Peru). Data cover the period from 07 November 2013 to 26 March 2019, recorded at hourly intervals. Measurements were obtained using MiniDOT datalogger (PME Inc., Vista, CA) installed 0.2 m above the seafloor on a metal frame by semi-autonomous diving. The data recorded in the table correspond to temperature (Temp_fond), dissolved oxygen saturation (DO_sat), and the time in UTC−05:00 (Hora_Lima). The fixed station was located in Constante (5°40’33.3” S, 80°54’1.6” W). A portion of these environmental records has been previously used in peer-reviewed publications, including: Cueto-Vega, R., Flye-Sainte-Marie, J., Aguirre-Velarde, A., Jean, F., Gil-Kodaka, P., and Thouzeau, G.

Cueto-Vega and has been harmonized for use in the manuscript “Biological Response Matrix for risk management of bottom-cultured Peruvian scallops under oxygen deficiency, temperature, and exposure-time stressors” (in review). The unified database supports the analysis of environmental variability during years with and without mass-mortality events of A. purpuratus, and the development of a Biological Response Matrix .本数据集包含秘鲁塞丘拉湾康斯坦特养殖区紫扇贝（Argopecten purpuratus，Peruvian scallop）底播养殖相关的海洋学观测记录，涵盖底温（单位：摄氏度）与溶解氧饱和度（单位：百分比）。数据采集时段为2013年11月7日至2019年3月26日，采样间隔为每小时1次。观测数据通过安装于海底上方0.2米金属架上的MiniDOT数据记录仪（PME Inc., 美国加利福尼亚州维斯塔市）获取，部署方式为半自主潜水作业。表格中记录的数据包括底温（Temp_fond）、溶解氧饱和度（DO_sat）以及采用UTC-05:00时区的时间（Hora_Lima，利马时间）。固定监测站位于康斯坦特海域（南纬5°40′33.3″，西经80°54′1.6″）。 部分环境观测数据此前已应用于经同行评议的学术出版物，包括： 1.
