Aerial water sampling drone.
The drone and sampling equipment can fly out over the lake and gather water from the surface layer a transitional layer and a deep layer to account for thermal and chemical stratification.
In this video we demonstrate a multi rotor aerial vehicle that can obtain water samples in remote and hard to access locations.
Advancements in drone technology have seen the development of drone assisted water sampling payloads resulting in the ability of drones to retrieve water samples and physico chemical data from aquatic ecosystems.
Among others aerial drones can be used as carriers for air sampling systems analyzers and sensors replacing or complementing the traditional ways to sampling at high altitudes such as airships aircrafts tethered balloons and meteorological towers.
A hyperspectral camera is mounted on this pelican drone.
The aerial drone first suspended a conductivity temperature depth ctd probe capable of measuring in situ parameters to a depth of 100 m and then suspended a water sampling device capable of collecting 2 l water samples up to 120 m deep.
To enable us to sample water quicker and more often without it having to cost more researchers from tu delft are developing a watertight drone capable of landing on and even diving under water automatically.
The solution also allows for the collection of in situ profiles of physiochemical parameters i e temperature electrical conductivity and water density.
Their outline of the kusatsu shirane volcano and the complete methodology uses a drone to sample the lake water from the crater lake a sampling device metal free bottle made of high density polyethylene for sampling as well as a couple of sampling procedures.
Water sampling uav in action collecting a sample at a depth of 80 meters the drone collected the water sample and the team was able to quickly analyze it for ph iron species and total arsenic using hatch s mobile water testing lab.
