Global port environmental data used for environmental distance calculations

This dataset contains a list of 8392 global commerical shipping ports, with geographic coordinates and four environmental variables (i.e. salinity, mean temperature during the warmest month, mean temperature during the coldest month and annual average temperature (all at water surface)). Data were primarily sourced from the U.S. National Oceanic and Atmospheric Administration World Ocean Atlas. Data for estuarine and riverine ports has been corrected, where better information was available, with particular focus on Canadian port data and top last-ports-of-call for ships arriving to Canada.

本数据集收录了8392个全球商业海运港口的相关信息，包含地理坐标与四项环境变量，分别为盐度、最暖月平均水温、最冷月平均水温及年平均水温（以上指标均取自水面观测值）。数据集的核心数据来源于美国国家海洋和大气管理局世界海洋图集。针对河口港与内河港的相关数据，在可获取更优质可靠信息的前提下已完成校正，其中特别聚焦于加拿大港口数据，以及抵达加拿大的船舶的主要最后挂靠港口数据。
