Data for 2016-2017 hydrologic year has been added by Sarah Strand as part of the Permafrost thermal state in Svalbard 2017-2018 (PermaSval) project, a research infrastructure access project funded by the Svalbard Integrated Arctic Earth Observing System (SIOS). Overall and long-term site responsible is Mauro Guglielmin of University of Insubria, Italy.


The study site is set in the Brogger Peninsula (78°55’ N, 11°51’ E), close to the village of  Ny- Ålesund. In particular the borehole is located on almost flat zone called Kolhaugen, between the coast and the Austre Broggerbreen forefield. The borehole is at 55 m a.s.l. very close less than 100 m southeastward from the Climatic Change Tower of CNR (Italy). Geologically the surface is composed by loose deposits (mainly marine beach deposits and rock weathered in situ-colluvium) with a not well developed soil above. Several inactive sorted circles occur in the area as well as some soli-gelifluction lobes and terraccettes. The study area lies in a polar semi-desert  where three main vegetation types occur: 1) ridge vegetation with mesic conditions dominated by Dryas octopetala L. and Cassiope tetragona (L.) D. Don., 2) snow-bed vegetation with snow cover persistence dominated by Salix polaris Wahlenb., 3) heath vegetation where snow melt occurs early dominated by Carex rupestris All. and Saxifraga oppositifolia L..  Mosses and lichens are widespread in all the three types of vegetation.


Flat structural knob covered by at least  2.89 m of sediments but probably weathered rock (mainly sandstone) is present down to 10.45 m of depth. Snow is generally thin respect the surrounding areas (<0.3 m). Drilling operations were without any fluids (except for compressed air) starting with dry coring down to 2.89 m and afterwards partially without coring (hammer) with the collection of cuttings every visible changes. Ice content visible in the sediments both as interstitial and segregated ice needs to be analysed as well as the cores. The borehole has been drilled with a diameter of 51 mm. An  hpd  case with an internal diameter of 29 mm  and ceiled at bottom was installed too. At the top the case is encapsulated in a bigger pipe (50 mm of diameter) that from the borehole reach the datalogger. Note that for firmware problems the data between 18 July 2015 to 26/01/2016 are too noisy to be accepted.
