Meta-data and dive summary

This file has two tabs. The first tab provides the meta-data collected along with each deployment, such as sex and age of each bird. The second tab tabulates the depth and duration of all dives completed by chick-rearing birds within the dataset that were >5 m in depth. We assumed that the pressure sensor of all Lotek TDRs were comparable. However, as we deployed Little Leonardo and Lotek TDRs simultaneously, we were able to demonstrate that they agreed on dive duration but not dive depth. All Little Leonardo depth values in this spreadsheet have been converted to their equivalent Lotek depth using the equation given in the manuscript: Lotek Depth = 0.897*(Little Leonardo Depth) + 0.781 (R2 = 0.998). Care should be taken when comparing different devices because of differences in the calibration of the pressure transducer and because larger devices impact the dive behaviour of murres (Elliott et al. 2007. CJZ).本数据集文件包含两个工作表。第一个工作表收录了随每次设备布放采集的元数据，涵盖每只鸟类的性别与年龄信息。第二个工作表统计了本数据集中育雏鸟类完成的所有深度大于5米的潜水的深度与时长。 我们假定所有Lotek TDR（时间深度记录仪）的压力传感器性能一致。然而，由于我们同时布放了Little Leonardo与Lotek TDR设备，得以证实二者在潜水时长的记录上保持一致，但在潜水深度的记录上存在显著差异。 本表格中所有Little Leonardo的深度数据均已按照论文中给出的公式转换为等效的Lotek深度值：Lotek深度 = 0.897×(Little Leonardo深度) + 0.781（决定系数R²=0.998）。 由于压力传感器的校准存在差异，且体型更大的设备会影响海鸦的潜水行为（Elliott等，2007，《加拿大动物学杂志》（CJZ）），因此在比较不同设备的观测结果时需格外谨慎。
