Tracking Data for Spectacled Eiders (Somateria fischeri)

This data release includes 2 child items with tracking data for Spectacled Eiders, a seaduck species that breeds only in Alaska and Russia and spends the winter exclusively in the Bering Sea. The Alaska breeding population is listed as threatened under provisions of the Endangered Species Act.
Child Item 1: "Argos Satellite Tracking Data for Spectacled Eiders (Somateria fischeri) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters.
Child Item 2: "Argos Satellite Tracking Data for Spectacled Eiders (Somateria fischeri) - Raw Data" -- All raw data collected from Argos satellite transmitters, provided for completeness of the archive. The quality-controlled, "Argos Processed Data" (Child Item 1) are better suited for most analytical purposes.

本次发布的数据包含2个子数据集，均为眼镜绒鸭（Spectacled Eiders）的追踪数据。该物种为仅在阿拉斯加与俄罗斯境内繁殖的海鸭，越冬地仅限白令海。其阿拉斯加繁殖种群依据《濒危物种法》相关条款被列为受威胁物种。
子数据集1：《眼镜绒鸭（Somateria fischeri）Argos卫星追踪数据——经处理数据集》——该数据集为从Argos卫星发射器采集并经过质量管控的处理后追踪数据。
子数据集2：《眼镜绒鸭（Somateria fischeri）Argos卫星追踪数据——原始数据集》——该数据集包含从Argos卫星发射器采集的全部原始追踪数据，用于保障档案的完整性。经质量管控的“Argos处理数据集”（即子数据集1）更适用于绝大多数分析场景。
