title: Images of ground vegetation at 58 sites in Central and Eastern Yakutia, in Summer 2021 (RU-Land_2021_Yakutia)

description: Vegetation surveys were carried out in four different study areas in the Sakha Republic, Russia: in the mountainous region of the Verkhoyansk Range within the Oymyakonsky and Tomponsky District (Event EN21-201 - EN21-219), and in three lowland regions of Central Yakutia within the Churapchinsky, Tattinsky and the Megino-Kangalassky District (Event EN21220 - EN21264). The study area is located within the boreal forest biome that is underlain by permafrost soils. The aim was to record the projective ground vegetation in different boreal forest types studied during the RU-Land_2021_Yakutia summer field campaign in August and September 2021.Ground vegetation was photographed for different vegetation types within a circular forest plot of 15m radius. Depending on the heterogeneity of the forest plot, multiple vegetation types (VA, VB, or VC) were chosen for the survey. Up to four quadrats (2mx2m) were surveyed and photographed for each vegetation type. The centre of the circular plot was surveyed additionally. Up to four photos in landscape orientation were taken of each quadrat.In total, 328 quadrats or plot centres at 58 forest plots were photographed. All data were collected by scientists form the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) Germany, the University of Potsdam Germany, and the North-Easter Federal University of Yakutsk (NEFU) Russia.

title: Aggregated ground vegetation above-ground biomass at 56 sites in Central and Eastern Yakutia, in Summer 2021 (RU-Land_2021_Yakutia)

description: Aggregated above-ground biomass for ground vegetation is given in g per m² for each taxon at 56 sites. Total ground vegetation biomass in g per m² and in kg for the entire site.The vegetation surveys were carried out in four different study areas in the Sakha Republic, Russia: in the mountainous region of the Verkhoyansk Range within the Oymyakonsky and Tomponsky District (Event EN21-201 - EN21-219), and in three lowland regions of Central Yakutia within the Churapchinsky, Tattinsky and the Megino-Kangalassky District (Event EN21220 - EN21264). The study area is located within the boreal forest biome that is underlain by permafrost soils. The aim was to record the projective ground vegetation in different boreal forest types studied during the RU-Land_2021_Yakutia summer field campaign in August and September 2021.The ground vegetation above-ground biomass was measured for different vegetation types within a circular forest plot of 15m radius. Depending on the heterogeneity of the forest plot, multiple vegetation types (VA, VB, or VC) were chosen for the survey. One quadrat of 50x50 cm was harvested per vegetation type. All vegetation smaller than 40 cm was harvested. Biomass harvest was conducted just outside the circular forest plots, which will serve as long-term monitoring sites.Fresh weights were recorded in field and sub sampling conducted if necessary. Samples were later dried at 60°C until a constant weight was achieved and dry weight was recorded. Average ground vegetation biomass per plot was calculated by using a weighted average for each vegetation type.In total, 79 quadrats at 56 forest plots were harvested. All data were collected by scientists form the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) Germany, the University of Potsdam Germany, and the North-Easter Federal University of Yakutsk (NEFU) Russia.

title: Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2020-01-11

description: Raw data acquired by a JAVAD Delta 3 GNSS Receiver with a resolution of 50Hz on board RV Polarstern during the MOSAiC expedition.The data is stored in JAVAD's .jps format (JAVAD GNSS, GREIS – GNSS Receiver External Interface Specification, San Jose, USA, 2022 (download available at https://www.javad.com/jgnss/support/manuals.html)). Each file contains data of one day with a typical file size of 1GB. The receiver was equipped with a multi-frequency GNSS antenna which was mounted on the ship's observation deck. It has to be noted that the main mast and the ship's chimney lead to a shadowing of GNSS observation links in at least two directions seen from the antenna position. The data was collected for measuring scintillation activitiy in the central arctic. Processed scintillation measurements with a 1 minute resolution are available (doi:10.1594/PANGAEA.956019).

title: Visible (VIS) and shortwave infrared (SWIR) reflectance spectra of rock samples from the Mourne Mountains, NI

description: The Hyperspectral Analysis of the Mourne Mountains (HAMM) project was undertaken from 2020-2022 in Northern Ireland to integrate spectral, geochemical, and remote sensing data from an exposed, non-arid setting. Mourne Mountain Complex (MMC) samples were obtained by donation from the Geological Survey of Northern Ireland (GSNI) and the Sedgwick Museum (University of Cambridge) as well as from the field by the authors. Samples represent the 5 primary granite types (G1, G2, G3, G4, G5), other minor rock types, and alteration styles. Some sample donations were historic and exact locations unspecified. Their reported coordinates are best estimates from historic literature and projections to surface (see notes in the datasets).Whole rock samples were analysed at the Natural Environment Research Council (NERC) Field Spectroscopy Facility (FSF) at the University of Edinburgh, Scotland for visible (VIS) and shortwave infrared (SWIR) spectra (i.e. 350–2500 nm). Spectra were obtained using an Analytical Spectra Devices (ASD) FieldSpec3 spectroradiometer with contact probe attachment. The contact probe includes an internal, 4.5 W quartz tungsten halogen lamp attached to the unit by a fibre optic cable and a total viewing area of 12.7 mm by 10.6 mm. The instrument was left to stabilise for 2 hours on after starting up, then calibrated to a Spectralon™ white reference before each measurement. Each measurement comprises a batch of 25 complete spectra and multiple measurements were taken on each sample. Areas measured included fresh, least altered sections as well as their weathered/vegetated counterparts exposed at surface as well as hydrothermal veins and associated alteration, if present. The spectra from each sample were averaged in ViewSpecPro to create a representative "whole rock" spectrum that comprises the dataset. Some sample spectra were not averaged across the entire rock sample to better highlight the spectra for vein alteration assemblages and specific minerals (e.g. beryl from the Diamond Rocks).
