The supporting data for "Biochemical Drivers Accelerated Vertical Expansion of the North Pacific Oxygen Minimum Zone Compared to Tropical Regions"

The dataset includes the observed minimum dissolved oxygen (DOmin.mat), the upper and lower boundaries of global oceanic oxygen minimum zones (OMZs) from observations (OMZDepths.mat), and relevant environmental parameters from reanalysis datasets and climate models (environmental_parameters.mat).(1) In the DOmin.mat file:Contains only the DOmin variableColumns represent: observation year, longitude, latitude, and minimum dissolved oxygen valueEach row represents an observation record from different spatiotemporal pointsPrimary purpose: Spatial assessment of OMZ location(2) In the OMZDepths.mat file:Contains only the DOmin variableColumns represent: observation year, longitude, latitude, OMZ upper boundary depth, and OMZ lower boundary depthEach row represents an observation record from different spatiotemporal pointsPrimary purpose: Records observed OMZ boundary depths for global OMZ depth assessment(3) In the environmental_parameters.mat file:OMZlon and OMZlat record global OMZ coordinates (longitude and latitude) from 1960-2021OMZregional marks five study regions:<br>'1' = Arabian Sea [AS], '2' = Bay of Bengal [BB], '3' = North Pacific [NP], '4' = Equatorial North Pacific [ENP], '5' = Equatorial South Pacific [ESP]Variables:EnvironmentData_UB: Environmental variables from sea surface to OMZ upper boundaryEnvironmentData_LB: Environmental variables from OMZ lower boundary to 2000m depthEnvironmentData_Thickness: Environmental variables within OMZ depth range (between upper and lower boundaries)Temporal coverage: 1960-2021 (each row represents a year)Columns represent different environmental variables, as recorded in the varnames variable."<b>For specific implementation methods and analytical processes, please refer to this article.</b><br>

该数据集包含观测到的最小溶解氧数据（DOmin.mat）、基于观测的全球海洋最低氧区（Oceanic Oxygen Minimum Zones, OMZs）的上下边界数据（OMZDepths.mat），以及来自再分析数据集和气候模型的相关环境参数数据（environmental_parameters.mat）。(1) DOmin.mat文件：仅包含DOmin变量；列代表观测年份、经度、纬度和最小溶解氧值；每行代表不同时空点的观测记录；主要用途：海洋最低氧区（OMZ）位置的空间评估。(2) OMZDepths.mat文件：仅包含DOmin变量；列代表观测年份、经度、纬度、OMZ上边界深度和OMZ下边界深度；每行代表不同时空点的观测记录；主要用途：记录观测到的OMZ边界深度，用于全球OMZ深度评估。(3) environmental_parameters.mat文件：OMZlon和OMZlat记录了1960-2021年全球OMZ的坐标（经度和纬度）；OMZregional标记了五个研究区域：<br>'1' = 阿拉伯海 [AS]、'2' = 孟加拉湾 [BB]、'3' = 北太平洋 [NP]、'4' = 赤道北太平洋 [ENP]、'5' = 赤道南太平洋 [ESP]；变量包括：EnvironmentData_UB（海面至OMZ上边界的环境变量）、EnvironmentData_LB（OMZ下边界至2000米深度的环境变量）、EnvironmentData_Thickness（OMZ深度范围内（上下边界之间）的环境变量）；时间覆盖范围：1960-2021年（每行代表一年）；列代表不同的环境变量，具体信息记录在varnames变量中。<b>具体实现方法和分析过程请参考本文。</b><br>
