Northern bottlenose whale (Hyperoodon ampullatus) GBIF-derived occurrence records for Greenland waters — filtered dataset feb 2026

GBIF-mediated occurrence records for northern bottlenose whale (Hyperoodon ampullatus) in Greenland waters, downloaded from GBIF in Feb 2026 and filtered for use in spatial occurrence analysis. Records were excluded if coordinate uncertainty exceeded 50 km, if date information was invalid or missing, or if no coordinates were available. Duplicate records representing the same sighting encounter were deduplicated to one master record per encounter.Records are distributed across sources as follows: iNaturalist (n=10), DFO/At-Sea Fisheries Observer/NAFO (n=9), Observation.org (n=5), Happywhale (n=4), HMAP (n=2), and a material sample (n=1).本数据集为经全球生物多样性信息设施（Global Biodiversity Information Facility, GBIF）整编的格陵兰海域北瓶鼻鲸（Hyperoodon ampullatus）发生记录，于2026年2月从GBIF下载并经筛选后用于空间发生分析。所有记录均经过严格筛选：剔除坐标不确定性超过50千米、日期信息无效或缺失、无有效坐标的条目；同时针对代表同一次目击事件的重复记录完成去重处理，每个事件仅保留一条主记录。记录按来源分布如下：iNaturalist（n=10）、DFO/海上渔业观察员/NAFO（n=9）、Observation.org（n=5）、Happywhale（n=4）、HMAP（n=2）以及1份实物样本记录（n=1）。
