Annual arrival dates for chinstrap penguins on Signy Island at onset of breeding season, from 1996 to 2020.

This dataset comprises the annual count of chinstrap penguins arriving to Signy Island each breeding season, from 1996 to 2020. Penguins arriving at the beach in mid to late November (the austral summer) were counted. This monitoring contributes to the CCAMLR (Commission for the Conservation of Antarctic Marine Living Resources) Ecosystem Monitoring Program (CEMP) and is part of the annual seabird Long Term Monitoring carried out by the British Antarctic Survey at Signy Island. Ecosystems component of BAS Polar Science for Planet Earth Programme, funded by NERC.

本数据集收录了1996年至2020年各繁殖季中，抵达锡尼岛（Signy Island）的帽带企鹅（chinstrap penguin）年度种群数量统计结果。统计工作针对每年南夏（南半球夏季）的11月中下旬抵达海滩的企鹅开展。本监测项目隶属于南极海洋生物资源养护委员会（Commission for the Conservation of Antarctic Marine Living Resources, CCAMLR）生态系统监测计划（CEMP），同时也是英国南极调查局（British Antarctic Survey, BAS）在锡尼岛实施的年度海鸟长期监测工作的组成部分。该项目属于英国南极调查局“极地科学为地球计划（Polar Science for Planet Earth Programme）”的生态系统分支项目，由英国自然环境研究委员会（Natural Environment Research Council, NERC）资助。
