Behavioral datasets of wandering albatrosses collected at Possession Island, Crozet, France, in 2019 and 2020

The relationship between the environment and marine animal small-scale behavior is not fully understood. This is largely due to the difficulty in obtaining environmental datasets with a high spatiotemporal precision. The problem is particularly pertinent in assessing the influence of environmental factors in rapid, high-energy-consuming behavior such as seabird take-off. To fill the gaps in the existing environmental datasets, we employed novel techniques using animal-borne sensors with motion records to estimate wind and ocean wave parameters and evaluated their influence on wandering albatross take-off patterns. Measurements revealed that wind speed and wave heights experienced by wandering albatrosses during take-off ranged from 0.7 ~ 15.4 m/s and 1.6 ~ 6.4 m, respectively. The four indices measured (flapping number, frequency, sea surface running speed, and duration) also varied with the environmental conditions (e.g., flapping number varied from 0 to over 20). Importantly, take-off..., The recorders, Ninja-scan (Little Leonardo, Tokyo, Japan), record triaxial acceleration at a very high time resolution (100 Hz). Ninja-scan also records 3D GPS positions (5 Hz), Doppler velocity (5 Hz), temperature (6 Hz), pressure (6 Hz), geomagnetism (6 Hz), and angular velocity (100 Hz). There are two types of Ninja-scans with different battery masses (Naruoka et al., 2021). Small Ninja-scans weighed 28 g, which is 0.3 ~ 0.4% of wandering albatross body mass, and are expected to record for 7 h. Large Ninja-scans weighed 91 g, which corresponds to 0.8 ~ 1.3% of wandering albatross body mass, and are expected to record for 65 h.
Ninja scans were attached to breeding wandering albatrosses at Possession Island, Crozet archipelago (46°25 S, 51°44 E) in the South Indian Ocean in 2019 and 2020. In 2019, 12 small Ninja scans were attached (in tandem) to 6 individuals. On each bird, one recorder had a delay timer so that the two recording periods did not overlap. Additionally, 15 birds had in..., , # Behavioral datasets of wandering albatrosses collected at Possession Island, Crozet, France, in 2019 and 2020

环境与海洋动物小型行为之间的关联尚未被完全阐明，这主要源于获取高时空精度环境数据集的难度较大。这一问题在评估环境因素对海鸟起飞这类快速高能耗行为的影响时尤为突出。为填补现有环境数据集的空白，本研究采用搭载运动记录功能的动物携带传感器的创新技术，对风速与海浪参数进行估算，并评估了其对漂泊信天翁起飞模式的影响。实测结果显示，漂泊信天翁起飞过程中遭遇的风速范围为0.7~15.4 m/s，浪高范围为1.6~6.4 m。本次测量的四项指标（振翅次数、振翅频率、海面行进速度与持续时长）同样随环境条件变化（例如振翅次数介于0至20余次不等）。值得注意的是，起飞……

本研究使用的Ninja-scan（日本东京Little Leonardo公司出品）记录仪，可实现极高时间分辨率下的三轴加速度记录（100 Hz）。此外，该设备还可记录三维GPS位置（5 Hz）、多普勒速度（5 Hz）、温度（6 Hz）、气压（6 Hz）、地磁数据（6 Hz）以及角速度（100 Hz）。

Ninja-scan记录仪存在两种不同电池重量的型号（Naruoka等，2021）：小型Ninja-scan重量为28 g，约占漂泊信天翁体重的0.3%~0.4%，预计可连续记录7小时；大型Ninja-scan重量为91 g，约占漂泊信天翁体重的0.8%~1.3%，预计可连续记录65小时。

2019年与2020年，研究团队在南印度洋克罗泽群岛的波塞申岛（46°25′S，51°44′E）为繁殖期的漂泊信天翁部署了Ninja-scan记录仪。2019年，共为6只信天翁（每只同时搭载两台）部署了12台小型Ninja-scan记录仪，其中每只信天翁搭载的一台记录仪设有延迟计时器，以确保两段记录时段互不重叠。此外，另有15只信天翁……
