1970s - 1980s Kooyman-Billups TDR Dive Records from Weddell Seals in McMurdo Sound

This dataset includes dive records from Weddell seals located in McMurdo Sound, Antarctica from the austral summers of 1978, 1979, and 1981 using Kooyman-Billups Time Depth Recorders. The data were recovered from photocopied paper scrolls using a code package (https://doi.org/10.5281/zenodo.6528846). This recovery process involved record scanning, image processing, and bias correction such that the historic data are directly comparable with dive data from modern instruments. This dataset contains the scanned images of the paper dive records (KBTDR_record_scans) and comma-separated value files of the dive data after recovery (KBTDR_data). Only records from McMurdo Sound were recovered, but record scans from Terra Nova Bay and White Island are also provided for future long-term studies on diving behavior.

本数据集收录了1978、1979及1981年南半球夏季，于南极麦克默多湾（McMurdo Sound）使用库伊曼-比卢普斯时间深度记录仪（Kooyman-Billups Time Depth Recorders）获取的威德尔海豹（Weddell seals）潜水记录。本数据集通过配套代码包（https://doi.org/10.5281/zenodo.6528846）从影印纸质卷轴中完成数据还原，该还原流程涵盖记录扫描、图像处理与偏差校正环节，可确保历史数据与现代仪器采集的潜水数据具备直接可比性。本数据集包含纸质潜水记录的扫描图像文件（KBTDR_record_scans）以及还原后潜水数据的逗号分隔值文件（KBTDR_data）。本次数据还原仅覆盖麦克默多湾的记录，但同时提供了特拉诺瓦湾（Terra Nova Bay）与怀特岛（White Island）的记录扫描图像，以供未来开展潜水行为相关的长期研究使用。
