Work Package 2: Seabird movement ecology (5000cg)
seabird movement
Since the first deployment of a biologging tag on a seabird in 1990 (38), scientists have used GPS and satellite tags to record fine scale movement, geolocators to record broad movements over very long temporal scales, time-depth recorders (TDRs) for underwater depth profiling and accelerometers for 3D movement and energetic proxies (Table 1). This wealth of data is truly unique in nature and allows the movement of birds both in air and water to be mapped across across space and time. The existing datasets, shared with the global seabird tracking database, exceed 5 million data points (Table 1) and the project already has the support of many of the largest data holders including Centre d’Etudes Biologiques de Chizé (18 species), British Antarctic Survey (XX species), Museum of New Zealand Te Papa Tongarewa (XX species). In this project we will reconstruct individual trajectories, across varying temporal scales to enable analysis of movement decisions across the ocean. Specifically, we will examine small scale decisions between sequential locations, and broader movement patterns in relation to infrasoundscapes.
