they are single species groups
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.
