Atmospheric Sampling on Ascension Island Using Multirotor UAVs
As part of an NERC-funded project investigating the southern methane anomaly, a team drawn from the Universities of Bristol, Birmingham and Royal Holloway flew small unmanned multirotors from Ascension Island for the purposes of atmospheric sampling. The objective of these flights was to collect air samples from below, within and above a persistent atmospheric feature, the Trade Wind Inversion,...
متن کاملHigh Resolution Atmospheric Sensing Using UAVs
A technique to obtain high resolution atmospheric data using small mobile sensors is presented. A fluid based control scheme using smoothed particle hydrodynamics (SPH) is implemented to perform field measurements in a leaderfollower arrangement for a team of unmanned aerial vehicles (UAVs) equipped with environmental sensors. A virtual leader is created by using a reduced density SPH particle ...
متن کاملSome case histories from Ascension Island.
THE physician of today is aware of the numerous adverse effects and potential hazards of modern drug therapy, and it is both refreshing and instructive to look back to the days when the physician's 'armentarium' of therapeutic agents was of 'narrow spectrum', and when many of the 'drugs' available were basically only of 'nutritive' value. Such retrospective views, even though they are often bri...
متن کاملAutonomous Recovery of a Fixed-Wing UAV Using a Net Suspended by Two Multirotor UAVs
This article presents a novel recovery method for fixed-wing Unmanned Aerial Vehicles (UAVs), aimed at enabling operations from marine vessels. Instead of using the conventional method of using a fixed net on the ship deck, we propose to suspend a net under two cooperative multirotor UAVs. While keeping their relative formation, the multirotor UAVs are able to intercept the incoming fixed-wing ...
متن کاملAn odyssey of the green sea turtle: Ascension Island revisited.
Green turtles (Chelonia mydas) that nest on Ascension Island, in the south-central Atlantic, utilize feeding grounds along the coast of Brazil, more than 2000 km away. To account for the origins of this remarkable migratory behavior, Carr and Coleman [Carr, A. & Coleman, P. J. (1974) Nature (London) 249, 128-130] proposed a vicariant biogeographic scenario involving plate tectonics and natal ho...
