title: Soil Water, plant xylem water, and leaf wax hydrogen isotope survey from Toolik Lake Area 2013-2014

description: This dataset accompanies a manuscript published in Geochimica et Cosmochimica Acta (http://dx.doi.org/10.1016/j.gca.2017.06.028). The leaf wax (n-alkane and n-acid) hydrogen isotopes are a common proxy for paleoclimate reconstructions from lake sediment cores. Yet, the interpretation of leaf wax hydrogen-2/hydrogen-1 (2H/1H) records hinges on our understanding of the modern systematics of water isotope fractionation and source water seasonality within ecosystems and among different plant species. This dataset contains hydrogen (and oxygen) isotope data from Arctic Alaska, measured in precipitation, soil water, as well as plant xylem and leaf water from two common tundra species, Betula nana and Eriophorum vaginatum. In addition to the water isotope measurements, this data package contains leaf wax distributions and 2H/1H values for the same two species, as well as in surface sediment samples from a suite of lakes and in sediment trap samples collected from the Arctic Long Term Ecological Research (ARC LTER) study lake, Lake E5.

title: Ice core data of Sodium (Na), Chlorine (Cl), and Acidity from 6 Greenland ice cores 1750-2012

description: Tropospheric reactive chlorine impacts the oxidation capacity of the atmosphere and may be influenced by anthropogenic activity, with potential implications for Northern Hemisphere ice core records of chlorine since the Industrial Revolution. Anthropogenic impacts on chlorine include direct emission of hydrochloride acid (HCl) from combustion, the mobilization of HCl from sea salt aerosol driven by atmospheric acidity, and heterogeneous chemistry converting sea salt chloride into reactive gaseous chlorine species (e.g., chlorine nitrite (ClNO2)). Here we present ice-core chlorine (Cl), sodium (Na), and acidity records from six Greenland ice cores (ACT_11d, Summit07, Summit10, Tunu, NEEM, NGT_B19). ACT_11d ice core was drilled in year 2011 at 66.5 ºNorth (N), 46.3 ºWest (W). Summit07 ice core was drilled in year 2007 at 72.6 ºN, 38.6 ºW. Summit10 ice core was drilled in year 2010 at 72.3 ºN, 38.3 ºW. Tunu ice core was drilled in year 2013 at 78.0 ºN, 33.9 ºW. NEEM ice core was drilled in year 2011 at 77.5 ºN, 51.1 ºW. NGT_B19 was drilled in year 1993 at 78.0 ºN, 36.4 ºW. Precise locations and other information are summarized in Ice Core Information.csv. Details on core extraction and dating are described in previous publications (Geng et al., 2014; Iizuka et al., 2018; McConnell et al., 2019; Opel et al., 2013; Spolaor et al., 2016). Ice core records are separated into two files: GreenlandIceCoreIonConcentration.csv contains ion concentration of Na and Cl, and calculated acidity (H+) for Summit07 ice core, GreenlandIceCoreElementalConcentration.csv contains elemental concentration of Na and Cl, and measured acidity for other Greenland ice cores.

title: 14C (Carbon-14) ages of Holocene lake drainage events on the North Slope of Alaska, 2019-2020

description: Lakes are abundant features on coastal plains of the Arctic, providing important fish and wildlife habitat and water supply for villages and industry, but also interact with frozen ground (permafrost) and the carbon it stores. Most of these lakes are termed "thermokarst" because they form in ice-rich permafrost and gradually expand over time. The dynamic nature of thermokarst lakes also makes them prone to catastrophic drainage and abrupt conversion to wetlands, called drained thermokarst lake basins (DTLBs). Together, thermokarst lakes and DTLBs cover up to 80% of arctic lowland regions, making understanding their response to ongoing climate change essential for coastal plain environmental assessment. Dating the timing of lake drainage can improve our understanding of the causes and consequences of DTLB formation. This suite of 14C (Carbon-14) ages provides insight into the timing of lake drainage on the North Slope of Alaska across a range of ecosystems and surficial geology types.

title: Radiocarbon dates from ice-edge ice-entombed tundra plants around the Orion and Serpens ice complexes, northern Baffin Island, Canada in 2018 and 2019

description: Radiocarbon dates on formerly ice-entombed tundra plants collected within 1 meter (m) of the current ice margin of rapidly receding ice caps on northern Baffin Island to test the concept of volcanic forcing on episodic ice cap expansion during the Common Era. The goal of this project is to examine the rate of onset of persistent Little Ice Age (LIA) cold by dating 50 new samples from current ice margins from ice complexes in Baffin Island, Canada, and comparing them to similar collections from 2005. If LIA ice expansion was abrupt and persistent then dates on the new plants should be about the same age as the 2005 samples, 200 to 500 m distant. Whereas if summers slowly cooled over decades-to-centuries through the late Holocene, then the new dates will be significantly older than their 2005 counterparts. Collectively, these data will provide the most robust testing of an abrupt onset of LIA cold and will be of interest to the sea ice and climate modeling communities.

title: In situ Magnesium/Calcium (Mg/Ca) and oxygen isotope (d18O) measurements in Neogloboquadrina pachyderma shells collected in 1999 by a MultiNet tow from different depth intervals in the Fram Strait

description: This dataset includes chemical and isotopic measurements on shells of the planktic foraminifera Neogloboquadrina pachyderma sinistral, collected by plankton tows (MultiNet) from eight stations across the Fram Strait (sites ARK XV/2 77-84). The sampled depth intervals are 0-50 meters (m), 50-100 m, and 100-200 m. Individual shells were analyzed in situ for their magnesium/calcium (Mg/Ca) ratios by Laser Ablation Inductively Coupled Mass Spectrometry (LA-ICP-MS), and for their stable oxygen isotope composition (d18O) by secondary ion mass spectrometry (SIMS). In addition, pooled shells were analyzed for d18O by acid-digestion isotope ratio mass spectrometry (IRMS). The purpose of this project was to determine the Mg/Ca:temperature sensitivity of the lamellar calcite (also called ontogenetic calcite) of N. pachyderma shells. Reference temperatures for the depth intervals sampled by MultiNet are available from parallel measurements using a conductivity temperature depth probe (CTD). A second objective of this project was to gain new insights into the d18O-temperature relationship of N. pachyderma by using two different analytical techniques (SIMS and IRMS).

title: Surface sediment samples collected from the Canadian Coast Guard Ship (CCGS) Sir Wilfrid Laurier 2019, Northern Bering Sea to Chukchi Sea

description: The Pacific sector of the Arctic Ocean is experiencing major reductions in seasonal sea ice extent and increases in sea surface temperatures. One of the key uncertainties in this region is how the marine ecosystem will respond to seasonal shifts in the timing of spring sea ice retreat and/or delays in fall sea ice formation. Variations in upper ocean water hydrography, planktonic production, pelagic-benthic coupling and sediment carbon cycling are all influenced by sea ice and temperature change. To more systematically track the broad biological response to sea ice retreat and associated environmental change, an international consortium of scientists have developed a coordinated Distributed Biological Observatory(DBO) that includes selected biological measurements at multiple trophic levels, along with satellite and mooring measurements. The DBO currently focuses on five regional biological "hotspot" locations along a latitudinal gradient that allows for consistent sampling and monitoring at five biologically productive locations across a latitudinal gradient: DBO 1 (SLIP)-south of St. Lawrence Island (SLI), DBO2 (Chirikov)-north of SLI, DBO3 (southern Chukchi Sea), DBO4-NE (northeast) Chukchi Sea, and DBO5-Barrow Canyon.

title: Leaf-level gas exchange, Moist acidic tundra snowfence, Toolik Lake Field Station, Alaska, 2016

description: Snow accumulation and retention patterns in the Arctic are undergoing rapid change, with consequences for critical ecosystem processes and climate feedbacks. We used a 22-year International Tundra Experiment (ITEX) snow manipulation experiment with increased and decreased winter snow treatments to quantify how winter snow depth affects leaf-level ecophysiology and plant use of snow meltwater. We coupled measurements of leaf-level gas exchange and leaf tissue chemistry (%N, %C, δ13C, and δ15N) with an analysis of stable isotopes (δ18O and δ2H) in active layer water, precipitation, and stem water. This is the leaf-level gas exchange dataset for four community dominants, Salix pulchra, Betula nana, Eriophorum vaginatum, and Ledum palustre.

title: Tundra shrub ring widths in microns, North Slope Alaska 1965-2013

description: Thermokarst disturbance in permafrost landscapes is likely to increase across the tundra biome with climate warming, resulting in changes to topography, vegetation, and biogeochemical cycling. Tundra shrubs grow on permafrost, but shrub - thermokarst relationships are rarely studied in detail. Since the 1980’s, Alaska’s North Slope has experienced increased thermokarst activity, including retrogressive thaw slumps (RTS) on hillslopes. Within decades, RTSs near Toolik Lake, Alaska, were colonized by tall (≥ 0.5 meters (m)) deciduous shrubs. We used dendrochronology methods on 66 shrubs (182 stem cross sections) representing dominant deciduous species: willows (Salix pulchra and Salix glauca) and dwarf birch (Betula nana) at two RTS chronosequences on Alaska’s North Slope comprising seven sites, to quantify thermokarst and climate effects (25 years of temperature and precipitation records) on shrub secondary growth (i.e., annual rings) in RTS-disturbed and undisturbed moist acidic tussock (MAT) tundra. Across species, average growth ring widths were 2 x wider for shrubs in RTSs than in MAT, and ring widths decreased with RTS age. A 1 degree Celsius (°C) June temperature increase was associated with 2% wider rings across species and sites, but shrubs showed marginal growth in warmer summers, supporting tundra-wide shrub climate sensitivity studies. A 4.5% average ring width increase per 1 mm of previous year’s September precipitation was seen in shrubs in mid-successional RTSs, suggesting protective effects of early snowfall in RTSs versus open tundra. RTS age category explained 47% and 30% of average ring width variance of willows and dwarf birch, respectively, in linear mixed effects models. Climate variables explained 2% average ring width variance across species. Our results suggest that RTS exert strong successional effects on tundra shrub growth. Climate effects appear to show weaker synoptic patterns across the study area. RTS will likely contribute to tundra greening where RTS activity is increasing.

title: Drained Lake Basin classification based on Landsat-8 imagery, North Slope, Alaska 2014 -2019

description: This data set contains a classification of the North Slope, Alaska for drained lake basins (DLBs) based on Landsat-8 imagery of the years 2014-2019 and Arctic Digital Elevation Model (ArcticDEM) data. Drained lake basins (DLBs) are often the most common landforms in lowland permafrost regions in the Arctic (50% to 75% of the landscape). However, detailed assessments of DLB distribution and abundance are limited. This data set is based on a novel and scalable remote sensing-based approach to identify DLBs in lowland permafrost regions, using the North Slope of Alaska as a case study. The data set was validated against several prior sub-regional scale datasets and manually classified points. The study area covers greater than 71,000 square kilometers (km2), including a greater than 39,000 km2 area not previously covered in existing DLB data sets. Within the data set, three classes are present: DLB/ambiguous/noDLB. Areas classified as ambiguous could not be classified as DLB or noDLB with sufficient certainty. Users may decide on a case by case basis if they wish to use the conservative estimate of DLB area, therefore omitting areas classified as ambiguous, or to use all three classes.

title: In situ Magnesium/Calcium (Mg/Ca) and oxygen isotope (d18O) measurements in Neogloboquadrina pachyderma shells collected in 2006 and 2007 in sediment traps moored in the Irminger Sea

description: This dataset includes chemical and isotopic measurements on shells of the planktic foraminifera Neogloboquadrina pachyderma sinistral collected in April 2006 and April 2007 from two sediment traps moored in the Irminger Sea (IRM-3, 59°14.86’North (N), 39°39.47’West (W) and IRM-4, 59°14.85’N, 39°39.47’W). Individual shells were analyzed in situ for their magnesium/calcium (Mg/Ca) ratios by Laser Ablation Inductively Coupled Mass Spectrometry (LA-ICP-MS), and for their stable oxygen isotope composition (d18O) by secondary ion mass spectrometry (SIMS). Hydrographic measurements reveal that the water column at sample location is isothermal and isohaline during the month prior to collection. The purpose of this project was to determine potential differences in the Mg/Ca or d18O composition of the lamellar calcite, formed and the upper water column, and the crust calcite, precipitated in deeper waters but at the same temperature and salinity than the lamellar calcite.
