Heat flow, thermal gradient and thermal conductivity data for Pescadero Basin (cruise FK181031, 2018)

This data set consists of thermal gradients and thermal conductivity to compute the heat flux in Pescadero Basin, Gulf of California. The data have been processed to convert from resistance to temperature using calibrations for each thermistor. Heat flow was estimated by combining the thermal gradient and thermal conductivity using the Bullard method. The data set was collected using a custom 1-m long ROV heat flow probe from Andrew Fisher, UC Santa Cruz. The heat flow probe was deployed on dives S0193-S0199 with ROV SuBastian during Falkor cruise FK181031, operated by Schmidt Oceanographic Institute. Each deployment of the heat flow probe lasted approximately 15 minutes. The data file is in tab-separated ASCII text format with column headers and units; the header block gives explanatory notes. The data set was generated as part of a heat flow study in the Gulf of California and was supported by National Science Foundation grant OCE16-34536 to Rob Harris.

本数据集包含热梯度（thermal gradients）与热导率（thermal conductivity）数据，用于计算加利福尼亚湾佩斯卡德罗海盆（Pescadero Basin, Gulf of California）内的热通量（heat flux）。本数据集已完成预处理工作：针对每只热敏电阻（thermistor）的校准参数，将原始电阻值转换为温度数据；热流（heat flow）可通过结合热梯度与热导率数据，并采用巴拉德法（Bullard method）估算得到。本数据集由加州大学圣克鲁兹分校Andrew Fisher团队定制的1米长遥控无人潜水器（Remotely Operated Vehicle, ROV）热流探针采集获得，该探针搭载遥控无人潜水器SuBastian，在施密特海洋研究所（Schmidt Oceanographic Institute）运营的法尔克号（Falkor）FK181031航次中，于S0193至S0199次下潜任务中完成布放作业，单次布放作业的持续时长约为15分钟。数据文件采用制表符分隔的ASCII文本格式，包含列标题、单位信息，头部区块附带说明性注释。本数据集作为加利福尼亚湾热流研究项目的一部分生成，由美国国家科学基金会（National Science Foundation）OCE16-34536号项目资助Rob Harris研究团队。
