Abstract: Lake Bolshie Toroki is located in Novosibirsk Region (55.39350 N, 80.61860E), Russia. It is an undrained lake with an area of 9.57 km2 and a depth of about 1m, with weakly alkaline and weakly mineralized (845 mg/l) water. Aquatic vegetation is predominantly represented by pondgrass (Potamogeton) and watermilfoil (Myriophyllum). The surrounding onland vegetation consists of agricultural lands with birch groves and marshy lowlands. Boreholes were drilled in the summer of 2012 in the middle of Lake Bolshie Toroki.

Abstract: Arctic snowfall climatology produced from the version R05 of the CloudSat 2C-SNOW-PROFILE product is available. It covers the 2007-2010 period over the latitudes from 58.5°N to 82°S. The monthly snowfall rates in this file have been calculated using the observations with: - a snow retrieval status lower than 3 - and a snowfall rate surface confidence > 1 Additionnaly, the monthly surface snowfall rate uncertainties, number of CloudSat orbits as well as number of observations are available. The number of observations over these 4 years is not sufficient to consider snowfall rates monthly (Edel et al. 2020). If one wants to obtain monthly snowfall rates, it is necessary to average multiple years.

Abstract: The dataset compiles in situ observational data obtained during the PHYTO-FRONT cruise (2014-02-03 - 2014-02-07) of central-southern Chile. The data includes conductivity, temperature, depth and potential density. Nutrient data, total and size-fractionated chlorophyll a measurements and data from plankton samples for composition and abundance of the micro-phytoplankton (microdiatoms) size fraction are also included.

Abstract: We infer seafloor topography of the inner continental shelf of northeast Greenland from airborne gravity disturbance measured by National Aeronautics and Space Administration's Oceans Melting Greenland (OMG) mission through a nonlinear inversion method called simulated annealing, and results in a model with 1.95~3.9 km resolution and 73.69 m accuracy. The model provides a reliable view of the seafloor near Zachariæ Isstrøm glacier, where bathymetric survey tracks are sparse.

Abstract: We analysed water samples taken during the Polarstern PS113 cruise with HPLC technique to retrieve phytoplankton pigment concentrations. We further used these data to obtain major phytoplankton groups following the diagnostic pigment analysis. We also measured at discrete light stations (called Lightstations) and from an undulating platform towed behind the ship (called TRIAXUS stations) radiometric underwater light profiles high spectrally resolved. We obtained high resolution phytoplankton group Chla data from depth resolved apparent optical properties derived from the underwater radiation data by applying an empirical orthogonal function (EOF) analysis to the spectral data set and developing subsequently regression models using the pigment based phytoplankton group Chla and the selected EOF modes. Results were obtained from using depth resolved transmission data (Transmission) and also from using the mean diffuse attenuation over the first optical depth (kdmean) of the measured radiometric profile. All the details are described in the related publication by Bracher et al. (2020).

Abstract: Current warming, shifting hydrological regimes and accelerated permafrost thaw in the catchment of the Arctic rivers will affect their water biogeochemistry. The Lena River is the second largest Arctic river and 71 % of its catchment is characterized by continuous permafrost. Monitoring of Arctic rivers will enable to observe expected changes in matter transport such as an increase of dissolved organic matter (DOM) re-mobilization from permafrost. A number of biogeochemical variables are presented here in a unique high frequency throughout the whole year. The sampling of Lena River water is done near the Research Station Samoylov Island in the central Lena River Delta. The Samoylov research station allows a unique chance for continuous sampling since it operates throughout the year.

Abstract: This dataset contains merged monthly mean MODIS-AERONET aerosol optical depth data from January 2002 to December 2016. The method to merge the two datasets is based on the Ensemble Kalman Filter and is described in detail in doi:10.1029/2019JD031884.

Abstract: These data report surface mass balance (SMB) stake measurements at the frontal part of Gourdon Glacier on James Ross Island, northern Antarctic Peninsula. The measurements were conducted by drilling stakes made of bamboo or aluminium into the ice. Changes in the height above the glacier surface were measured in yearly field campaigns during January/February from 2014 until 2017. The resulting height differences in meter ice equivalents [SMB (m i.e.)] are presented together with the coordinates [Latitude Start (°)], [Longitude Start (°)], [Latitude End (°)], [Longitude End (°)] and the elevation in regard to the WGS84 ellipsoid [Altitude Start (m)] and [Altitude End (m)] for the start and the end date of each measurement period. GNSS measurements were done with a single-frequency hand-held Garmin GPS 60. The mass balance measurements were not corrected for movement within one yearly measurement period.

Abstract: The database is an array of minute resolution observations over the rainfall of weather stations of the Urals (Russia). The database contains observational data on pluviographs at 79 meteorological stations located in the regions of the Russian Federation: Sverdlovsk region; Perm Territory; Chelyabinsk region; Kurgan region. The period for which the data is placed is from 1936 to 2015. Category: geoscientificInformation Source: Not Available Supplemental Information: Please note: If the precipitation data goes from one calendar day to another, then for all continuous rain a single date is indicated that corresponds to the date the rain began. This is due to the fact that the authors are developing an automated computer program for data processing, and the algorithm of the program contains the conditions for the uniformity of the date for one continuous rain.
