title: Annotated images capturing fish abundances during the first deployment of the EMSO Generic Instrument Module (EGIM) at the OBSEA cabled observatory from December 2016 to April 2017

description: Here we present fish observation data obtained during the first EGIM deployment at the OBSEA observatory, which led to the development of a methodology for correlating fish activity and biologically relevant oceanographic variables. In addition to salinity, temperature, sound speed, water depth and dissolved oxygen data measured by the EGIM, two underwater digital cameras were deployed to provide ecological observations: a CAM1 camera rotating 360° and five metres apart, and a fixed CAM2 camera pointed at an artificial reef where fish activity is observed. For the analysis, the two close cameras were considered as one. For each image, the total number of fish was counted. All visible individuals were taxonomically classified as detailed as possible, using the latest scientific nomenclature from FISHBase.

title: Snow surface accumulation measured using Bamboo stake measurents, EastGRIP camp Greenland, May 2016

description: Description of record: Surface accumulation obtained from the 200 bamboo stake measurements carried out from 2016 at EastGRIP camp Greenland. The record gives the relative surface height change compared to May 10 2016 in cm. Method: 200 bamboo stakes (wooden sticks with less than 1 cm in diameter) were setup up on a line perpendicular to the prevailing wind, which was approximately West-Southwest. The bamboo stakes were separated with 1 meter, except between stake 100 and 101, where were separated by about 5 meters. During the summer season May to August the height of the individual stakes would be measured every few days depending on weather. The measurements were carried out using a ruler and the estimated precision is less than 0.5 cm. The stakes would at the end of the season be lifted to be easily located when the team would come back in spring after the winter. Measurements of the stakes would be carried out in spring before lifting the stakes to obtain estimate of amount of accumulation during the period August to May. The relative surface height change was obtained by averaging the height change of the 200 stakes.

title: Last interglacial and penultimate glacial sea surface temperature anomalies: summary statistics for the region south of 40°S, resampled to 2000 year resolution

description: Southern Ocean marine sediments provide an important archive of Quaternary glacial-interglacial climate changes. Sea surface temperature (SST) reconstructions in the Southern Ocean depend exclusively on the fossils or geochemical signatures of planktic organisms, but the strengths of these SST proxies remain poorly quantified in this region. To improve confidence in Southern Ocean paleoclimate reconstructions, we first evaluated the reliability of SST proxies employed at Quaternary glacial-interglacial time scales, focusing on three key potential problems: advection/dispersion, seasonality, and non-thermal influences. On that basis, we selected foraminifera assemblages, long-chain alkenones (UK'37 index), diatom assemblages, and the Globigerina bulloides Mg/Ca ratio as the most reliable SST proxies in the Southern Ocean. We also revised calibrations where appropriate, using core-top sediment databases. Overall, Southern Ocean SST reconstructions using these recommended proxies and calibrations should be robust when averaging across multiple sites and proxy types, but should be treated with caution when analysing spatial variability, a small number of sites, or a single proxy type. We have applied these recommendations to a synthesis of Southern Ocean SST over the penultimate glacial and last interglacial (LIG). Similar to previous studies, we find that LIG warming at 40°S to 60°S reached 1.6 ± 1.1°C (annual mean) or 1.9 ± 1.3°C (austral summer: JFM) relative to present. Annual / summer cooling in the penultimate glacial maximum reached -3.6 ± 1.0°C / -4.0 ± 1.2°C, similar to the last glacial maximum. Compared with the previous LIG SST syntheses, our reported uncertainties more strongly reflect geographic variability and dating errors, as we have reduced errors in the individual temperature reconstructions and do not date records by aligning peaks in their SST.

title: Potential CO2 and CH4 production in the central Lena River Delta, Kurungnakh and Samoylov Islands from 12 permafrost profiles sampled in 2018

description: Arctic warming increases the degradation of permafrost soils but little is known about floodplain soils and other permafrost soils in the permafrost region. This dataset present soil properties from twelve analyzed cores located in the northeastern Siberian Lena River Delta within the continuous permafrost zone in northern Yakutia, Russia that were sampled in 2018. The cores represent intact yedoma, yedoma thaw slumps, and floodplain profiles. The soil coring and sampling was carried out in August 2018 for a total of 30 soil cores, 35 soil profiles, and 341 sediment samples. First, vegetation and other characteristics of the plots were described. Then, the active layer soils were excavated, described, and sampled with a fixed volume cylinder (250 cm³). Then the permafrost layers were sampled with a modified, snow, ice, and permafrost (SIPRE) auger to a depth of 1 m (core diameter of 7.62 cm) and visually described in their characteristics. Each core was divided into subsamples with 5-10 cm length according to its facies horizons, transported frozen to Alfred Wegener Institute in Potsdam, and stored at -20 °C until analysis. A subset of these sediment samples (n=105 from 12 cores) were later analyzed in the laboratory for physical and chemical properties. Selected samples were further analyzed for radiocarbon, grain size analysis, and potential CH4 and CO2 production using aerobic and anaerobic soil incubations for 356-days at 20 °C.

title: Occurence of sponges and associated fauna on the Schultz Bank (Flank) during GO Sars cruise GS2018108 in 2018

description: In 2014, two experimental Agassiz trawls were conducted on the Schulz Bank; one at the summit (568–670 m depth) and one on the southwestern flank (1,464 m depth). The 3-m-wide Agassiz trawl, with a 1 cm mesh size in the cod-end, was towed along the seafloor for 676 m on the summit and 441 m on the flank, resulting in a disturbed area of 2,028 and 1,323 m², for the summit and flank, respectively. Towing speed was maintained at around 2 knots and the initial and final position were recorded. In August 2018, the two trawl marks and four additional control transects (one on either side of the trawl mark) were surveyed while onboard the R/V G.O.Sars. Video recordings were taken along the trawl marks and control transects with the ROV AEGIR6000. Control transects were located 50 m to the east and west of each trawl mark and were performed parallel to the mark.

title: Magnetic surface flux data and spatial information of magnetic grains from a Hawaiian lava and results of using this data for Micromagnetic Tomography

description: Micromagnetic Tomography is a new technique which combines magnetic surface scan of a sample with spatial information (shape, location) of magnetic grains. Combining these two datasets enables us to overcome the non-uniqueness in the inversion and thus we can allocate magnetizations to individual grains that best reproduce the magnetic surface scan. This is a step into understanding how magnetic fields are recorded in magnetic grains, which is relevant for the field of paleomagnetism.
description: The data in this repository consists of three parts; (1) the magnetic surface scan, (2) the spatial data and (3) the raw dataset. The orientation and scale of file 1 matches the orientation and scale of file 2. This means that using file 1 and 2, an inversion for the magnetic grains can be performed. If the exact same procedure is used as described in the manuscript this dataset is supplement to, then the magnetizations from file 3 can be reproduced. The magnetizations in file 3 can also be filtered and interpreted to reproduce various figures from the manuscript.

title: Abiotic data from Billefjorden Svalbard in August 2022

description: Kelps act as ecosystem engineers and foundation species, providing the food web basis for Arctic coastal, rocky shore ecosystems. Arctic fjords are undergoing large climatic changes, with the consequences of glacial and terrestrial run-off on kelp holobionts largely being unknown. We compared areas being influenced by either glacial or terrestrial run-off with a control area in Billefjorden, Svalbard in August 2022. In each area, we measured water parameters of the upper 10 m, taking CTD profiles (SWiFT CTDplus Turbidity, Valeport, St Peters Quay, United Kingdom). Further, we measured the underwater light climate (RAMSES-ACC-UV/VIS radiometer, TriOS Optical Sensor, Oldenburg, Germany). In each area, the water's trace elemental composition at 0 and 5 m water depth (Agilent 8900, Agilent Technologies; Tokyo, Japan) was analysed, as well as the relative abundance of the free-living microbial community at 5 m water depth (16S; Illumina Nova platform, Shanghai Hanyu Biotech lab, Shanghai, China).

title: Kelp holobiont responses to run-off in Billefjorden, Svalbard in August 2022

description: Kelps act as ecosystem engineers and foundation species, providing the food web basis for Arctic coastal, rocky shore ecosystems. Arctic fjords are undergoing large climatic changes, with the consequences of glacial and terrestrial run-off on kelp holobionts largely being unknown. We compared areas being influenced by either glacial or terrestrial run-off with a control area in Billefjorden, Svalbard in August 2022. Kelps were collected from three sampling stations (A-I) per area, with a plant rake (Plant rake 19.000, acc. to Sigurd Olsen, KC Denmark, Silkeborg, Denmark) on 5±2 m water depth. Silica-dried meristematic tissue was used for biochemical (pigment, antioxidant activity) analyses. The tissue above the meristem was rinsed with ultrapure water and freeze-dried, before elements were measured of homogenized, digested material with a triple quadrupole ICP-MS/MS system (Agilent 8800, Agilent Technologies; Tokyo, Japan). For microbial analyses, an area of 10×10 cm above the meristem was swabbed with a sterile cotton swab. The V4-V5 regions (515F: 5'-GTGCCAGCMGCCGCGGTAA-3' and 907R: 5'-CCGTCAATTCMTTTRAGTTT-3') of the bacterial 16S rRNA gene from DNA extracts were amplified and sequenced using the Illumina Nova platform (Shanghai Hanyu Biotech lab, Shanghai, China).
