Lena Delta 2019 Magnetic Snow Depth Probe data
This dataset consists of over 2000 snow depth and position (GNSS) measurements collected on Samoylov and Kurungnakh Islands in the Lena Delta, Russia, between March 31st and April 12th, 2019. These data were collected using an in-house (AWI) build magnetic snow depth probe (mSDP). It allows snow dep...

The accuracy of the magnetic depth measurement is approximately 0.1 cm; however, the overall accuracy of the depth measurement is significantly less (2 - 4 cm) due to uncertainties in the positioning of the tip in loose vegetation at the base of the snowpack.

This dataset consists of over 2000 snow depth and position (GNSS) measurements collected on Samoylov and Kurungnakh Islands in the Lena Delta, Russia, between March 31st and April 12th, 2019.

The device consists of a Magnetostrictive Transducer contained within a 1.5 m long stainless steel rod (the probe) which can very accurately measure the position of a magnet mounted on a plastic disk that slides up and down the rod. As the rod is inserted into the snow, the plastic disk remains on the snow surface.
