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. (2022). Size-based survival of cultured Argopecten purpuratus (L, 1819) under severe hypoxia.

ICES Journal of Marine Science, 76. https://doi.org/10.1093/icesjms/fsy171 The complete compiled dataset was provided by A. Aguirre-Velarde and R. 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 .
