title: Permafrost disturbance in Central Yamal along the Bovanenkovo railway line and thermokarst lakes, link to files in different formats

description: The data set presents results from geospatial analyses of a region in Central Yamal, Western Siberia, which was affected by the construction of the Bovanenkovo railway line and by high Retrogressive Thaw Slumps (RTS) occurrence in consequence of the extremely warm and wet year 2012. A change detection was performed using high resolution optical satellite images from 2010 (GeoEye-1) and 2013 (QuickBird). The preprocessing of the satellite data (orthorectification and atmospheric correction) was performed by and is described in Dvornikov et al., 2016. The degree of disturbance change from 2010 and 2013 around the railway line was classified into three major disturbance levels - low, medium and high, based on the width of disturbance and magnitude of change over the course of three years. A kernel density raster file illustrates RTS distribution. The highest disturbance along the railway can be observed, where the RTS activity is the highest in 2013.

title: Regional-Scale Forest Management Maps for the Continental United States

description: One main challenge in environmental and ecological research is to map land use, the human intent to modify the earth's cover, using satellite data. We have mapped forest management, a land use, in the southeastern and northwestern United States, 1.5 million square kilometers, at high spatial. This is a novel study using spectral time series analysis, expert derived training data and a random forest classifier to map forest management, calculate probability and uncertainty of class membership.

title: Carbon degradation rates, sulfate reduction rates and iron composition in soils flooded with seawater at Gyldensteen Strand, Denmark

description: Permanent flooding of low-lying coastal areas is a growing threat due to climate change and related sea-level rise. An increasingly common solution to protect coastal areas lying below sea level is intentional flooding by "managed coastal realignment". However, the biogeochemical implications of flooding agricultural soils with seawater are still not well understood. We conducted a 1-year mesocosm experiment to investigate microbial carbon degradation processes in soils flooded with seawater. Agricultural soils were sampled on the northern coast of the island Fyn (Denmark) at Gyldensteen Strand, an area that was subsequently flooded in a coastal realignment project. We found rapid carbon degradation to TCO2 1 day after experimental flooding and onwards and microbial sulfate reduction established quickly as an important mineralization pathway. Nevertheless, no free sulfide was observed as it precipitated as Fe-S compounds with Fe acting as a natural buffer, preventing toxic effects of free sulfide in soils flooded with seawater. Organic carbon degradation decreased significantly after 6 months, indicating that most of the soil organic carbon was refractory towards microbial degradation under the anoxic conditions created in the soil after flooding. During the experiment only 6-7 % of the initial soil organic carbon pools were degraded. On this basis we suggest that most of the organic carbon present in coastal soils exposed to flooding through sea-level rise or managed coastal realignment will be permanently preserved.

title: Effects of bedforms and large protruding grains on near-bed flow hydraulics in low relative submergence conditions

description: In mountain rivers, bedforms, large relatively immobile grains, and bed texture and topographic variability can significantly alter local and reach-averaged flow characteristics. The low relative submergence of large immobile grains causes highly three-dimensional flow fields that may not be represented by traditional shear stress, flow velocity, and turbulence intensity equations. To explore the influence of large protruding grains and bedforms on flow properties, we conducted a set of experiments in which we varied the relative submergence while holding the sediment transport capacity and upstream sediment supply constant. Flow and bed measurements were conducted at the beginning and end of each experiment to account for the absence or presence of bedforms, respectively. Detailed information on the flow was obtained by combining our measurements with a 3D numerical model. Commonly used velocity profile equations only performed well at the reach scale when shallow flow effects and the roughness length of the relatively mobile sediment were considered. However, at the local scale large deviations from these profiles were observed and simple methods to estimate the spatial distribution of near-bed shear stresses are likely to be inaccurate. Zones of high turbulent kinetic energy occurred near the water surface and were largely controlled by the immobile grains and plunging flow. The reach-averaged shear stress did not correlate to depth or slope, as commonly assumed, but instead was controlled by the relative boulder submergence and degree of plunging flow. For accurate flow predictions in mountain rivers, the effects of bedforms and large boulders must be considered.

title: Humification Index values of the dissolved organic matter extracted from sediment samples collected from the shoreline of Koumoundourou lake

description: Sediment samples collected from the shoreline of Koumoundourou lake in the western part of Attiki peninsula, 15 km far from Athens the capital of Greece, were treated with a 4 mM CaCl2 solution for the extraction of DOM, at a substrate: solution ratio equal to 1:4. The solutions were shaken for 15 min, centrifuged at 6000 rpm for 20 min at 10 °C and filtered through a 0.4 µm pore polycarbon filter. DOM extracts were characterized by fluorescence spectroscopy. Spectra were obtained by a Perkin-Elmer LS 55 luminescence spectrophotometer equipped with the WinLab 4.00.02 software for data processing. Humification Index values were calculated according to Ohno (2002)

title: Annotated record of the detailed examination of an Mn deposit uncovered at US Coast Guard Station NOVEMBER in the Pacific Ocean

description: An extremely large manganese encrusted rock (allegedly called, manganese nodule) inadvertently retrieved by the USGC PONTCHARTRAIN (WHEC-70) during a deep Nansen cast on Ocean Station NOVEMBER in 3749 meters of water in September 1967. This specimen, weighing approximately 240 Kg., was entangled in the oceanographic cable which was accidentally laid on the bottom. Scientists from the Scripps Institution of Oceanography subsequently identified the rock as probably the largest manganese nodule ever found. At that time, the term "manganese nodule" was still used to describe any deepsea recovery of a manganese surfaced object as in the case of the famous "Horizon" nodule (NTHL-10 at https://doi.pangaea.de/10.1594/PANGAEA.854965) which revealed to be a large slab of altered volcanics (clayey palagonite) covered with a thick manganese crust.

title: (Tables 1,2 and 3, pages 853-854) Isotopic data for the solid-phase of three sediment box cores from the DOMES Sites A, B and C in the Pacific Ocean

description: Determination of radium, thorium, uranium isotopes, and 210Pb in sediments and sediment pore waters from North Equatorial Pacific deep-sea clay-silicous oozes shows that the radium and uranium isotopes are mobile in the pore water. The concentration-depth profiles of radium can be understood in terms of a diagenetic model which takes into account mixing of sediment particles by bioturbation, molecular diffusion in the pore water, adsorption onto particle surfaces, as well as radioactive production and decay. The 234U/238U activity ratios in several samples are higher than the seawater value, indicating some enrichment of 234U in the pore water. However, the absolute concentrations of 238U and 234U are 25% lower than those in seawater, suggesting that the sediments form a sink for uranium isotopes. 210Pb is present in the pore water at concentrations approx. 20% that of 226Ra. The origin of 210Pb in the pore water is uncertain and could be due either to its in situ mobilization in the sediments or subsequent production in the laboratory from the decay of 222Rn. 230Th is present in measurable concentrations in the pore waters, but its distribution does not show any systematic trend with depth or other parameters. The most likely source of 230/Th appears to be minute amounts of sediment particles collected in the pore waters during the squeezing operation.

title: Annotated record of the detailed examination of Mn deposits offshore the island of Oahu, Hawaii Archipelago

description: Occurrences and associations of ferro-manganese deposits at relatively shallow depths in the Hawaiian Archipelago were revealed by a series of cruises on the R/V Teritu. The deposits are accreting principally on the three prominent terrace levels around all of the Islands-at 400 to 800 meters, 1200 to 1600 meters, and 2400 meters as crusts and pavements. In some instances, examples of deposits at low depth demonstrate the rapid growth of ferro-manganese oxides and the importance of seed material for manganese coating to grow on artificial seeds. A large number of iron and steel samples encrusted with ferromanganese deposits have been collected by divers during the past year off Oahu beaches.

title: Classification (a land abandonment map) from 1990 to 2000 across Poland, Belarus, Latvia, Lithuania and European Russia

description: Institutional settings play a key role in shaping land cover and land use. Our goal was to understand the effects of institutional changes on agricultural land abandonment in different countries of Eastern Europe and the former Soviet Union after the collapse of socialism. We studied 273 800 km**2 (eight Landsat footprints) within one agro-ecological zone stretching across Poland, Belarus, Latvia, Lithuania and European Russia. Multi-seasonal Landsat TM/ETM+ satellite images centered on 1990 (the end of socialism) and 2000 (one decade after the end of socialism) were used to classify agricultural land abandonment using support vector machines. The results revealed marked differences in the abandonment rates betweencountries. The highest rates of land abandonment were observed in Latvia (42% of all agricultural land in 1990 was abandoned by 2000), followed by Russia (31%), Lithuania (28%), Poland (14%) and Belarus (13%). Cross-border comparisons revealed striking differences; for example, in the Belarus-Russia cross-border area there was a great difference between the rates of abandonment of the two countries (10% versus 47% of abandonment). Our results highlight the importance of institutions and policies for land-use trajectories and demonstrate that radically different combinations of institutional change of strong institutions during the transition can reduce the rate of agricultural land abandonment (e.g., in Belarus and in Poland). Inversely, our results demonstrate higher abandonment rates for countries where the institutions that regulate land use changed and where the institutions took more time to establish (e.g., Latvia, Lithuania and Russia). Better knowledge regarding the effects of such broad-scale change is essential for understanding land-use change and for designing effective land-use policies. This information is particularly relevant for Northern Eurasia, where rapid land-use change offers vast opportunities for carbon balance and biodiversity, and for increasing agricultural production on previously cultivated lands.
