Cormorant Oceanography Project: Biologging Data from Black-faced Cormorants (Phalacrocorax fuscescens), Australia, 2022 & 2023

Oceanographic sampling of the coastal ocean is often sparse in space and time and in situ observations are needed to understand the complex physical processes in this zone. This dataset is provided by the Cormorant Oceanography Project (https://www.osudashcams.com/), an interdisciplinary collaboration between oceanographers and seabird ecologists based at Oregon State University, and in partnership with collaborators globally. We are advancing biologging tag technologies for use with cormorant species to measure in situ oceanographic conditions. This also offers a unique opportunity to study the distribution and behaviors of cormorants relative to environmental conditions along their daily foraging paths. Our biologging tags include combinations of fast-response sensors to measure water temperature, conductivity, and pressure. Each tag contains an inertial measurement unit (IMU) to monitor acceleration and orientation. A GPS unit, triggered when a bird surfaces, provides locations for georeferencing measurements. The sensors collect large volumes of data that are transmitted and retrieved using two-way cellular communications. This dataset consists of GPS tracks and dive profiles from black-faced cormorants (Phalacrocorax fuscescens) tagged on Notch Island, off the southeast coast of Australia, during the 2022 and 2023 breeding seasons. Cormorants were fitted with GPS-GSM tags with integrated fast response temperature, and depth sensors and were tracked through their post-breeding migration.近岸海域的海洋学采样在时空维度上往往较为稀疏，亟需通过原位观测来解析该区域的复杂物理海洋过程。 本数据集由鸬鹚海洋学项目（Cormorant Oceanography Project，https://www.osudashcams.com/）提供，该项目由俄勒冈州立大学的海洋学家与海鸟生态学家开展跨学科合作，并与全球各地合作伙伴联合推进。 我们正研发适用于鸬鹚物种的生物记录标签技术，以原位采集海洋环境参数。该技术同时为研究鸬鹚在日常觅食路径上的分布、行为与环境条件的关联提供了独特契机。 我们的生物记录标签集成了多组快速响应传感器，用于测量海水温度、电导率与压强。每枚标签均搭载惯性测量单元（inertial measurement unit，IMU）以监测加速度与姿态。当鸟类浮出水面时触发的GPS单元可为地理参照测量提供位置信息。 上述传感器可采集海量数据，并通过双向蜂窝通信技术完成数据的传输与回收。 本数据集包含2022年与2023年繁殖季期间，在澳大利亚东南沿海诺奇岛（Notch Island）佩戴追踪标签的黑脸鸬鹚（Phalacrocorax fuscescens）的GPS轨迹与潜水剖面数据。 研究人员为黑脸鸬鹚佩戴了集成快速响应温度与深度传感器的GPS-GSM标签，并对其繁殖后迁徙过程进行了全程追踪。
