Abstract The Russian invasion of Ukraine hampers the ability to adequately describe conditions across Arctic, thus biasing view on Arctic change. Here we benchmark pan-Arctic representativeness largest high-latitude research station network, INTERACT, with or without stations. Excluding stations lowers markedly, some biases being same magnitude as expected shifts caused by climate change end century.
Arctic sea-ice loss is emblematic of an amplified water cycle and has critical feedback implications for global climate. Stable isotopes (δ 18 O, δ 2 H, d-excess ) are valuable tracers constraining climate processes through space time. Yet, the paucity well-resolved isotope data preclude empirically derived understanding hydrologic changes occurring today, in deep (geologic) past, future. To address this knowledge gap, Pan-Arctic Precipitation Isotope Network (PAPIN) was established 2018 to...
Abstract Since the 1978 discovery of an islet “Oodaaq Island” north Greenland, then considered to be northernmost island in world, multiple islets have been reported and apparently disappeared with regular intervals permanent sea ice-covered area offshore part Greenland. In this paper, we report results comprehensive investigations at all quoted positions islets, bathymetry measurements, as well supplementary lidar, ice thickness gravity measurements during a helicopter reconnaissance. The...
Abstract Relative sea level (RSL) data derived from isolation basins at Innaarsuit, a site on the south shores of large marine embayment Disko Bugt, West Greenland, record rapid RSL fall limit (ca. 108 m) 10,300–9900 cal yr B.P. to reach present 3500 Since 2000 B.P., rose ca. 3 m present. When compared with elsewhere in our results suggest that was deglaciated later and more quickly than previously thought, or slightly before 10,300 The northern part Bugt experienced less rebound 10 6000...
A coordinated geological-archaeological investigation has been carried out in southern Disko Bugt with the primary purpose of elucidating Holocene relative sea-level (RSL) changes. Two RSL curves representing Early-Middle emergence respectively southeastern and southwestern have constructed. Elevations paleo-Eskimo sites different ages surveyed supplemented similar elevations compiled from literature. Detailed investigations at two partly submerged Dorset I sites. At both sites, stratigraphy...
The climatic control on fluvial fluxes of sediments and solutes from arctic terrestrial ecosystems to the hydrographically sensitive highly productive marine ecosystem are considered be an important feedback mechanism in relation understanding global change. High temporal resolution data presented water discharge, suspended sediment transport, solute chemistry river Zackenbergelven draining a catchment 512 km2 Arctic Northeast Greenland. Variations quality discharge discussed climate,...

The geomorphology of a coarse clastic coastal landscape at Tuapaat (69°24'N 52°36'W), southeastern Disko Island, central West Greenland, is described, and morpho-stratigraphy the constructed. 14C ages on marine shells, whale bones, peat gyttja are used to construct relative sea level changes throughout Holocene. emergence SE Island occurred in early part Holocene limit situated ca. 80m a.s.l. Between 4.7 1.0ka BP, approached present it has probably been below between ka BP present. lowest...
Abstract Geografisk Tidsskrift, Danish Journal of Geography 97: 33–46, 1997. The coastal geomorphology three cuspate forelands at Saqqarliit Ilorliit, western Disko, West Greenland is described, sediment core data from salt marshes and lagoons are presented, an emergence curve constructed, discussed in relation to late Holocene relative sea-level (RSL) changes. On falling RSL early-middle was followed by rising Holocene. Emergence continued until c. 2.5 ka BP. Ilorliit suggest transgression...
