title: Western Alaska Lake Database: 2013-2014

description: This vector data layer covers 6 major lake districts (Baldwin Peninsula, Kobuk Delta, Selawik Lowland, Northern Seward Peninsula, Central Seward Peninsula, and Yukon-Kuskokwim Delta) in the northern and central sub-regions of the Western Alaska Landscape Conservation Cooperative (WALCC) region and consists of polygons of lakes with areas equal or greater than 1.0 ha. More than 70000 Lakes were mapped from Landsat OLI imagery acquired between 2013 and 2014 using Object-Based Image Analysis (OBIA) techniques with an classification accuracy of 96%. The spatial image resolution of Landsat OLI is 30 m. Permafrost characteristics and surficial geology associated with lake polygons were determined from the Alaska permafrost map (Jorgenson et al. 2008).

title: Using ground-penetrating radar, topography and classification of vegetation to model the sediment and active layer thickness in a periglacial lake catchment, Western Greenland, link to shapefiles

description: The geometries of a catchment constitute the basis for distributed physically based numerical modeling of different geoscientific disciplines. In this paper results from ground-penetrating radar (GPR) measurements, in terms of a 3-D model of total sediment thickness and active layer thickness in a periglacial catchment in western Greenland, are presented. Using the topography, the thickness and distribution of sediments are calculated. Vegetation classification and GPR measurements are used to scale active layer thickness from local measurements to catchment-scale models. Annual maximum active layer thickness varies from 0.3 m in wetlands to 2.0 m in barren areas and areas of exposed bedrock. Maximum sediment thickness is estimated to be 12.3 m in the major valleys of the catchment. A method to correlate surface vegetation with active layer thickness is also presented. By using relatively simple methods, such as probing and vegetation classification, it is possible to upscale local point measurements to catchment-scale models, in areas where the upper subsurface is relatively homogeneous. The resulting spatial model of active layer thickness can be used in combination with the sediment model as a geometrical input to further studies of subsurface mass transport and hydrological flow paths in the periglacial catchment through numerical modeling.

title: Seawater conditions during the experiment in May 2011 at the sampling sites off Vulcano Island

description: The impacts of ocean acidification on coastal biofilms are poorly understood. Carbon dioxide vent areas provide an opportunity to make predictions about the impacts of ocean acidification. We compared biofilms that colonised glass slides in areas exposed to ambient and elevated levels of pCO2 along a coastal pH gradient, with biofilms grown at ambient and reduced light levels. Biofilm production was highest under ambient light levels, but under both light regimes biofilm production was enhanced in seawater with high pCO2. Uronic acids are a component of biofilms and increased significantly with high pCO2. Bacteria and Eukarya denaturing gradient gel electrophoresis profile analysis showed clear differences in the structures of ambient and reduced light biofilm communities, and biofilms grown at high pCO2 compared with ambient conditions. This study characterises biofilm response to natural seabed CO2 seeps and provides a baseline understanding of how coastal ecosystems may respond to increased pCO2 levels.

title: Table 2: AMS radiocarbon ages from carbonate microfossils of sediment core MD97-2133

description: The ages are initially presented in conventional radiocarbon years (5730 a half-life), corrected for isotopic fractionation, and without reservoir correction. Samples with d13C values shown as 0 per mil produced insufficient CO2 to prepare an aliquot for 13C determination. The d13C value of 0 is assumed for these samples. An error in d13C of 1 per mil corresponds to an error of 8 radiocarbon years. The calibrated 14C ages (an approximate calendar timescale, pre-1950 AD) were calculated using the relationships provided by Stuiver and Reimer (1993), for samples with conventional ages less than 10 ka; and using Bard et al. (1998), for samples older than 10ka. For marine samples a reservoir correction of 400 years has been applied. No reservoir correction is applied for lacustrine samples (OZE 254, 259, 250, 251, 252, 253) because of the current absence of information concerninglacustrine 14C reservoir values for Lake Carpentaria.

title: Mg/Ca, Sr/Ca and Na/Ca measured by LA-ICP-MS on the deepwater bivalve Acesta excavata from Norway

description: We have measured Mg/Ca, Sr/Ca and Na/Ca in carbonate shells of the deepwater bivalve Acesta excavata. The samples were collected in the Sula reef and the Leksa reef on the Norwegian margin in summer 2014.Measurements were conducted using LA-ICP-MS.Laser ablation was performed using a Resolution M50 193 nm ArF Excimer Laser system (Resonetics), with a 72 μm beam diameter, a pulse rate of 10 Hz and 10 μm/s scan speed. Total sweep time was 0.65 s. Prior to the measurement a fast precleaning pass was conducted at 0.2 mm/s, 10Hz, and 104 μm laser spot size. Elemental ratio analysis was performed with a Thermo-Scientific ELEMENT XR sector field ICP-MS.In total, eight specimens were measured. In three specimens we measuerd perpendicular to the shell to investigate all shell layers. Additionally, we measured all eight samples in the fibrous and microgranular shell section (calcite). The measurements were taken from the ontogenetic oldest part of the bivalve (ventral side), spanning a length of 20 mm.

title: Chironomid-inferred July-air temperature of Lago Piccolo di Avigliana

description: Chironomid headcapsules were used to reconstruct late glacial and early-Holocene summer temperatures at Lago Piccolo di Avigliana (LPA). Two training sets (northern Sweden, North America) were used to infer temperatures. The reconstructed patterns of temperature change agreed well with the GRIP and NGRIP d18O records. Inferred temperatures were high during the Bølling (ca 19 °C), slowly decreased to ca 17.5 °C during the Allerød, reached lowest temperatures (ca 16 °C) during the Younger Dryas, and increased to ca. 18.5 °C during the Preboreal. The amplitudes of change at climate transitions (i.e. Oldest Dryas/Bølling: 3 °C, Allerød/Younger Dryas: 1.5 °C, and Younger Dryas/Preboreal: 2.5 °C) were smaller than in the northern Alps but similar to those recorded at another site in northeastern Italy. Our results suggest that (1) Allerød temperatures were higher in the southern Alps and (2) higher during the Preboreal (1 °C) than during the Allerød. These differences might provide an explanation for the different responses of terrestrial-vegetation to late glacial and early-Holocene climatic changes in the two regions. Other sites on both sides of the Alps should be studied to confirm these two hypotheses.

title: Last Glacial and Holocene dynamics override post-colonial disturbance in shaping genetic diversity of a heavily exploited palaeoendemic conifer, <em>Lagarostrobos franklinii</em>

description: The impact of past anthropogenic disturbance on the amount and
 distribution of genetic diversity is a key factor in determining the
 resilience of tree species to environmental change. This is particularly
 the case for narrowly distributed species where disturbance has impacted
 most of the species’ range. Here we examine the legacy of post-colonial
 logging and fire on patterns of genetic diversity in the Tasmanian
 palaeoendemic conifer Lagarostrobos franklinii (Podocarpaceae), a fire
 sensitive and slow growing rainforest tree valued for its durable timber.
 Thirty-three populations (12 of which represent primary stands) from
 across the species range were genotyped using eight nuclear SSRs (871
 samples) and MIG-seq-based single nucleotide polymorphisms (254 samples).
 Genetic differentiation was relatively high for conifers (Fst of 0.113 and
 0.143 for nuclear SSR and MIG-seq, respectively) with cryptic divergence
 between populations geographically close but in differing river catchments
 likely reflecting postglacial dispersal from distinct Last Glacial refugia
 and low levels of gene flow. Population level genetic diversity was
 greatest in the core of the range with no significant correlation with the
 history of post colonial human disturbance (i.e. primary vs. non primary
 stands) and, unexpectedly, given the greater impact of logging at lower
 elevations, a significant decline in allelic richness with elevation.
 Overall, this study shows that L. franklinii has been resilient to past
 timber exploitation and uncovers previously undetected genetic patterns.
 This shows that genetic tools can be invaluable in characterising species
 specific impacts of disturbance and in helping guide the ongoing
 conservation of important species.

title: Hydrological and meteorological investigations in a lake near Kangerlussuaq, west Greenland

description: Few hydrological studies have been made in Greenland, other than on glacial hydrology associated with the ice sheet. Understanding permafrost hydrology and hydroclimatic change and variability, however, provides key information for understanding climate change effects and feedbacks in the Arctic landscape. This paper presents a new extensive and detailed hydrological and meteorological open access dataset, with high temporal resolution from a 1.56 km**2 permafrost catchment with a lake underlain by a through talik close to the ice sheet in the Kangerlussuaq region, western Greenland. The paper describes the hydrological site investigations and utilized equipment, as well as the data collection and processing. The investigations were performed between 2010 and 2013. The high spatial resolution, within the investigated area, of the dataset makes it highly suitable for various detailed hydrological and ecological studies on catchment scale.
description: The dataset contains hydrological and meteorological data from a lake catchment in the Kangerlussuaq region, Western Greenland. The investigations were performed during 2010-2013 and the following parameters are included: Soil moisture, Soil temperature, Hydraulic properties of the active layer, meteorological parameters from a local weather station within the catchment, water levels and discharge, sublimation and evaportation measurments, snow depth and snow water content data and time lapse photos.

title: Short read assemblies of diverse Acacia species

description: The genus Acacia is the largest genus of plants in Australia, containing a
 remarkable amount of phenotype diversity and occupy all of the continent’s
 climatic zones (McLay et al. 2022; Renner et al. 2020; 2021). Multiple
 recent studies have reported the assembly of Acacia genomes at the
 chromosome level using long read technologies (A. pycnantha, McLay et al.
 2022;* A. confusa*, Chen et al. 2024; A. crassicarpa, Massaro et al. 2024;
 A. melanoxylon, Zhang et al. 2025). However, these sequencing efforts have
 been relatively restricted with major phylogenetic sections remain
 unrepresented, including the section Botrycephalae and the sister genus
 Paraserianthes. Genomes from these groups will better enable analyses of
 leaf morphological evolution within the genus Acacia and a better
 understanding of the origin of the genus since splitting from
 Paraserianthes nearly 23 million years ago (Macphail and Hill 2001). In
 this work, we generate a number of short read draft assemblies for six
 unsequenced Acacia species, one Paraserianthes species, and an additional
 genome for A. confusa. These short read libraries and their associated
 assemblies will be resources for comparative genomics of the genus, and
 can be used to inform further sequencing efforts for this group.
