We will develop and deploy new loggers to complement the analyses on pre-existing data. These loggers will simultaneously measure high resolution 3D and spatial movement, in combination with in situ measurements of sound, pressure and wind. These new loggers will be made by Sextant Technology Limited, New Zealand and will make use of miniaturised infrasound microphones, barometric pressure sensors to detect high and low pressure associated with weather, and sensor to detect the direction and speed of wind. All component parts already exist and so this project will involve only a small development period.
This data will produce the first data set in the world to simultaneously measure in situ infrasound, pressure or wind with 3D and spatial movement in any seabird species. This allow the fine scale movement of birds to be mapped directly to small scale fluctuations in infrasound and pressure. It will also have a feedback to infrasound models but calibrating models and allowing us to assess the correlation between pressure and infrasound. It will also allow us assess for the first time 3D movement responses of birds to localised wind conditions. This will allow us to estimate the potential energetic benefits of using optimal winds and the potential costs and benefits of diversions in flight paths to avoid extreme weather events.
