title: Geometric parameters of shoreface profiles of Laptev Sea erosion coast (Table 1)

description: Field investigations of the Laptev Sea shoreface morphology were carried out (1) off erosional shores composed of unconsolidated sediments, (2) off the modern delta shores of the Lena River, and (3) off rocky shores.It was found that profiles off erosional shores had a concave shape. This shape is not well described by commonly applied power functions, a feature, which is in disagreement with the generally accepted concept of the equilibrium shape of shoreface profiles. The position of the lower shoreface boundary is determined by the elevation of the coastal lowland inundated during the last transgression (at -5 to -10 m) and may easily be recognized by a sharp, an order of magnitude decrease in the mean inclination of the sea floor. The mean shoreface inclination depends on sediment grain-size and ranges from 0.0022 to 0.033. The concave shape of the shoreface did not change substantially during the last 20-30 years, which indicates that shoreline retreat did not slow down and hence suggests continued intensive coastal erosion in the 21st century.The underwater part of the Lena River delta extends up to 35 km offshore. Its upper part is formed by a shallow and up to 18-km wide bench, which reaches depths of 2-3 m along the outer edge. The evolution of the delta was irregular. Whereas some parts of the delta are advancing rapidly (58 m/year), other parts are eroding. Comparison of measured profiles with older bathymetric data gave an opportunity to evaluate the changes of the underwater delta over past decades. Bathymetric surveys of the seabed around the delta can thus contribute towards a quantification of the sediment budget of the river-sea system.In addition, some sections of the Laptev Sea coast are composed of bedrock that has a comparatively low resistance to wave erosion. These sections may supply a considerable amount of sediment, especially if the cliffs are high. This source must therefore also be taken into account when assessing the contribution of shore erosion to the Laptev Sea sediment budget.

title: (Table 1) Lithology and total organic carbon at DSDP Hole 61-462

description: The solvent-extractable lipids of Sections 462-49-4 (lower Maestrichtian), 462-54-2 (Campanian), and 462-59-1 (Cenomanian), from the Nauru Basin, were investigated for aliphatic and aromatic hydrocarbons, ketones, alcohols, and acids, after separation into acid and neutral fractions. Detailed analyses of the total neutral fraction revealed only n-alkanes, steranes, and triterpanes present in sufficient concentration (&gt;0.5 ng/100 g dry sediment for individual compounds) for component recognition. N-alkanes (C19-C35) constitute the major component of each section, with the most abundant present as 10 (n-C24), 135 (n-C29), 17 (n-C26) ng/100 g dry sediment in Sections 462-49-4, 462-54-2, and 462-59-1, respectively. The results suggest a high degree of thermal maturity of the lipids, which is interpreted in terms of the high geothermal gradient (about 50°C/km) and the regional volcanicity. The lipid data also suggest that the major source of organic matter was terrestrial and that deposition took place in a low-productivity oxic environment.

title: Investigation of abrupt cold events in the North Atlantic Ocean in a transient Holocene simulation

description: Abrupt cold events have been detected in numerous North Atlantic climate records from the Holocene. Several mechanisms have been discussed as possible triggers for these climate shifts persisting decades to centuries. Here, we describe two abrupt cold events that occurred during an orbitally forced transient Holocene simulation using the Community Climate System Model version 3. Both events occurred during the late Holocene (4305-4267 BP and 3046-3018 BP, respectively). They were characterized by substantial surface cooling (-2.3 and -1.8 °C, respectively) and freshening (-0.6 and -0.5 PSU, respectively) as well as severe sea ice advance east of Newfoundland and south of Greenland, reaching as far as the Iceland Basin in the northeastern Atlantic at the climaxes of the cold events. Convection and deep-water formation in the northwestern Atlantic collapsed during the events, while the Atlantic Meridional Overturning Circulation was not substantially affected (weakening by only about 10% and 5%, respectively). The events were triggered by prolonged phases of a positive North Atlantic Oscillation caused substantial changes in the sub-polar ocean circulation and associated freshwater transports, resulting in a weakening of the sub-polar gyre. Our results suggest a possible mechanism by which abrupt cold events in the North Atlantic region may be triggered by internal climate variability without the need of an external (e.g. solar or volcanic) forcing.

title: Raw data of continuous VM-ADCP (vessel-mounted Acoustic Doppler Current Profiler) profiles and DGPS during five cruises on board of MYA II in the Sylt-Rømø Bight

description: The data set, composed of raw vessel mouted ADCP and DGPS data obtained from five cruises on board of the Research Vessel "Mya II", crosses perpendicularly the Lister Deep inlet in two positions (outer and inner part), and three main tidal channels, named as Lister Ley, Højer Dyb, Rømø Dyb, in the Sylt-Rømø Bight. The cruises were conducted between May 22 and 30, 2018. Observational work consists in measurements which the vessel followed the same track multiple times during a determinate time. In addition, a Differential GPS worked together with the ADCP, providing water surface level data with high precision. The data was collected using a Teledyne RDI WorkHorse 600 kHz with an offset of 1.3 m related to the water surface. The rate sample was 2 s, with a bin size of 0.5 m and a blank distance of 0.5. DGPS collected horizontal and vertical position information in a sample rate of 1 second and a precision of 2 to 3 cm, using the WGS 84 geodesic system reference.

title: Global biomass density of potential wild large grazers for present-day and the last glacial maximum, simulated by a DGVM model

description: Large herbivores are a major agent in ecosystems, influencing vegetation structure and carbon and nutrient flows. Yet most of the current global dynamic vegetation models (DGVMs) lack explicit representation of large herbivores. Here we incorporated a grazing module in the ORCHIDEE-MICT DGVM based on physiological and demographic equations for wild large grazers, taking into account the feedbacks of large grazers on vegetation. The model was applied globally for present-day and the last glacial maximum (LGM).Three NetCDF files are included, corresponding to the model results for three periods: present-day (1960-2009 average), pre-industrial (1860-1899 average), and the last glacial maximum (ca. 21 ka before present). Variables include the modeled potential grazer biomass/population density, along with the directly relevant outputs: vegetation distribution (i.e. fractional coverage of the plant functional types), and gross and net primary productivity. Detailed model descriptions and the simulation setup can be found in: Zhu et al. (2018).

description: Total mesozooplankton biomass was measured as dry weight on a fresh sample. Samples were sieved on 200 µm nitex, briefly rinsed with distilled water to remove salt, transferred on pre-weighted alluminium foil and placed in an oven at 60°C. The samples were weighted on a microbalance after 24 hours and again 2-3 times within the following seven days, until the weight was constant. This latter value was considered as dry weight.

title: In situ measurements of freeze/thaw ground displacement in the Lena River Delta, 2013-2017, using steel pipes

description: In permafrost areas, seasonal freeze-thaw cycles of active layer result in upward and downward movements of the ground. Additionally, relatively uniform thawing of the ice-rich layer at the permafrost table can contribute to net long-term surface lowering. We use a simple method to quantify surface lowering (subsidence) and uplift in a yedoma area of the Lena River Delta, Siberian Arctic (Kurungnakh Island), using reference rods (metal pipes and fiberglass rods) installed deeply in permafrost. The metal pipes were 2 m long and 3 cm in diameter and were anchored at least 1 m below the typical active layer. The fiberglass rods were 2 m long and 1 cm in diameter and were anchored at least 70 m below the typical active layer. We assume, therefore, that the rods were motionless relative to the permafrost. The plexiglass plate with a size of 10 by 10 cm was fixed in its horizontal position by the rod but could move freely with the surface vertically along the rod. We repeatedly measured distance between the top of a rod and a plexiglass plate resting on the ground surface. Several distance measurements around each rod were taken at each visit and averaged. Altogether 12 metal pipes were installed at the study site in April 2013 and 19 fiberglass rods were installed in April 2014. Measurements were conducted during field campaigns from spring 2013 to summer 2017 with some gaps. We provide here the measured distances between the top of a rod and a plexiglass plate. To obtain the ground displacement, the user have to define the period of interest and calculate the displacement.
description: Measurements are the distances between the ground surface and the top of the metal pipe, in cm. To obtain the displacement, you need to subtract the measurement on a certain date from the reference measurement (e.g. from the very first one).
