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.
