    Thickness and properties of sea ice and snow of land-fast sea ice in Atka Bay in 2021 (2022)
    PANGAEA
    In:  Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven
    Details
    Publication Date: 2024-05-14
    Description: Manual measurements of sea ice thickness, sub-ice platelet layer thickness, freeboard, and snow thickness are distributed evenly and repeated along a 25km-long transect across Atka Bay every 2 to 4 weeks. At each measurement location, 5 holes were drilled through the ice in order to determine the aforementioned parameters, one in the center and one in a distance of five meters in each direction, to cover their small-scale spatial variabilities. The measurements have been mainly conducted by the meteorologist (Paul Ockenfuß) and Jess Bunchek, Tanguy Doron and Linda Ort of the overwintering team.

    Stationary echosounder (EK60, Simrad, 38 & 200 kHz) recordings from the central Red Sea near Thuwal, Saudi Arabia, between January 2014 and February 2016 (2023)
    PANGAEA
    Details
    Publication Date: 2024-05-14
    Description: Simrad EK60 echosounders (38 and 200 kHz) were deployed in the central Red Sea during several multiple-days periods between January 2014 and February 2016. Records were made in the deepest part of a ~700 m deep basin (22.5°N, 39.03°E) referred to as the Economic City Deep (ECDEEP) and at ~555 m along its sloping edge, and at a nearby 880 m deep station (22.08⁰N, 38.71⁰E). All locations were situated near the King Abdullah University of Science and Technology (KAUST) campus, Saudi Arabia. In the events marked by "bottom-mounted deployment" the echosounders were deployed on the bottom facing the surface. The floating mooring was connected to concrete weights by steel wires ensuring vertical orientation such that the transducers were located ca. 7 m off the bottom. The bottom-mounted deployments continuously recorded the movement and abundance of scattering layers and organisms over depth and time at a time resolution of ~0.5 pings/s. In the events marked by "profile", the echosounders were deployed facing downwards in a profile stopping at different depths for each ca. 15-30 minutes. During the profiles, a tungsten carbide (38.1 mm; theoretical target strength -42.3 dB and -38.9 dB on 38 and 200 kHz, respectively) calibration sphere was attached 10 m or 16 m below the echosounder rig as target strength reference. The dataset contains 12 events with in total 1317 raw proprietary Simrad EK60 data files with file sizes between 0.7 and 168 MB. The raw files include transducer configuration data and sample data (raw power (W) and angles (alongship and athwartship, °)).

    Alkalinity, DIC, δ13C-DIC, major and trace elements, and stable water isotopes data in water samples from a degrading permafrost landscape at subarctic Iskorasfjellet, northern Norway (2022)
    PANGAEA
    Details
    Publication Date: 2024-05-14
    Description: From September 22nd to October 6th 2020, we collected water samples daily from the outlet of the Gaskabohki catchment, a small subarctic watershed at the mountainside of Iskorasfjellet in northern Norway, to investigate how DIC (dissolved inorganic carbon) and AT (total alkalinity) may change under different environmental forcing (changing precipitation and temperature). We further sampled weekly (3x) at three stations upstream of the outlet to track the changes of the carbonate system with distance from the spring. Besides this temporal examination, we also expanded the investigation spatially, by collecting water samples from seven further catchments, some of which stretch as far as the Barents Sea with different lithologies and varying extent of permafrost. At all sampling sites, we collected water samples for DIC and AT, δ13C-DIC, major and trace elements, and stable water isotopes (δ18O-H2O and δ2H-H2O). We also recorded water temperature, electrical conductivity and turbidity. Finally, at the outlet of the Gaskabohki catchment, we performed a discharge measurement once a day, at the same time as taking the water samples.

    Raw data of GPS position and sea-surface temperature recorded by 44 Southtek NOMAD drifting buoys in the marginal ice zone north of Svalbard in 2022 (2023)
    PANGAEA
    Details
    Publication Date: 2024-05-14
    Description: 44 Southtek Iridium GPS drifters of types Offshore NOMAD-T V3 (33) and Offshore NOMAD V2 (11) were deployed in the marginal ice zone northwest of Svalbard as part of RV Polarstern expedition PS131 (ATWAICE) in July-August 2022. In addition to GPS position and time, the 33 NOMAD-T buoys also measured sea-surface temperatures. The 44 buoys were used for a total of 48 individual deployments, including 4 redeployments of recovered instruments, to either mark and track non-iridium instruments (6), to mark important sites (2), to track individual ice floes (1), or to elucidate the surface ocean currents as a complement to measurements obtained by the towed Triaxus system (31) or the ship-based CTD (8). The buoys were either thrown over board into open water, placed on sea ice, or attached to instruments. The measurement and transmission intervals were between 1 hour and 15 minutes, and were also partly reconfigured during operation. The drifter data were downloaded directly on board and displayed in the ship's Mapviewer software in near-real time, to facilitate navigation and to support the scientific program in decision-making. The attached .zip archive contains the original data files obtained from the Southtek server, which were partially modified to account for the 4 redeployments (indicated by "redeployed" in the filename), and to fill a data gap caused by an iridium data provider issue (indicated by "merged" in the filename). The files still include the deck test data, which needs to be removed according to the attached table with deployment metadata (including deployment time and position).

    High-frequency, year-round time series of the carbonate chemistry in a high-Arctic fjord (Svalbard) (2023)
    PANGAEA
    Details
    Publication Date: 2024-05-14
    Description: The Arctic Ocean is subject to high rates of ocean warming and acidification, with critical implications for marine organisms as well as ecosystems and the services they provide. Carbonate system data in the Arctic realm are spotty in space and time and, until recently, there was no time-series station measuring the carbonate chemistry at high frequency in this region, particularly in coastal waters. We report here on the first high-frequency (1 h), multi-year (6 years) dataset of salinity, temperature, dissolved inorganic carbon, total alkalinity, CO2 partial pressure (pCO2) and pH at a coastal site (12 m) in Kongsfjorden, Svalbard. We show that the choice of formulations for calculating the dissociation constants of the carbonic acid remains unsettled, (2) the water column is generally somewhat stratified despite the shallow depth, (3) the saturation state of calcium carbonate is subject to large seasonal changes but never reaches undersaturation (Oa ranges between 1.4 and 3.0) and (4) pCO2 is lower than atmospheric CO2 at all seasons, making this site a sink for atmospheric CO2.

    Raw data of sea ice inertial motion recorded by 15 OpenMetBuoys in the marginal ice zone north of Svalbard in 2022 (2023)
    PANGAEA
    Details
    Publication Date: 2024-05-14
    Description: A total of 15 OpenMetBuoys (OMBs) were deployed in the marginal ice zone northwest of Svalbard (array of 14 buoys) and on the fast ice off Greenland (one buoy) as part of RV Polarstern expedition PS131 (ATWAICE) in July - August 2022. The OMBs, also referred to as wave buoys, reported GPS position and wave spectra from 20-minute inertial motion averages at hourly intervals via the iridium satellite network. From these, significant wave height and peak wave period can be calculated. Two of the buoys ceased transmission within days of the deployment, while all other buoys recorded data for several weeks/months. The buoys were deployed on ice floes of various dimensions ranging from 15 m to as large as ~2km. The attached .zip archive contains a netcdf file incorporating all buoy data, several python scripts to read and process the data, as well as selected preliminary data quicklooks. The buoys were build and deployed as a collaboration between the Alfred-Wegener-Institute, the University of Tokyo, and the Norwegian Meteorological Institute.

    An 18 years sediment trap data: Original counting of organic-walled dinoflagellate cysts off Cape Blanc, Mauritania (2024)
    PANGAEA
    Details
    Publication Date: 2024-05-14
    Description: This dataset comprises the count data of organic-walled dinoflagellate cysts that were collected by the upper sediment trap on mooring CBi located offshore Cap Blanc, Mauritania between June 2003 and March 2020. The mooring coordinates varied between 20°44.9' - 20°45.7'N and 18°41.9' - 18°42.7'W at water depths between 1249 - 1364 m. The trap had a 0.5 m²opening aperture and material was collected at a 3 to 22 days resolution. In every sampling cup, the material was pre-fixed with HgCl2. Variation in the cyst flux and association composition provided insight into inter-annual to decadal natural and anthropogenic induced changes in the local upper water ecosystem and environment in this region that is characterized by year-round upwelling.

    Details
    Publication Date: 2024-05-14
    Description: During Polarstern expedition PS131 (ATWAICE: ATlantic WAter pathways to the ICE), a large number of autonomous instruments were installed on three representative ice floes across the marginal ice zone northwest of Svalbard in July 2022. The aim was to investigate sea ice summer melt processes, with a focus on the contribution of the Atlantic water inflow into the region. The attached .zip file includes raw data files obtained from all instruments deployed on the northernmost floe, also referred to as Floe North. Depending on the instrument, the data were transmitted via satellite, collected on internal memory, or both. The instruments were installed on Floe North on 13 July 2022, revisited for maintenance on 20 July 2022, and partially recovered on 30 July 2022. The sensors included 3 ADCPs in different configurations to measure ocean currents, a CTD buoy (SIT) with 6 SBE37IMP and an ECO Triplet fluorometer, a HOBO under-ice conductivity chain, 3 ice mass balance buoys (IMBs) of different types to determine ice surface and bottom melt, a radiation station equipped with 3 TriOS RAMSES radiometers to measure albedo and the under-ice light field, a Campbell Scientific weather station for atmospheric conditions, an OpenMetBuoy (OMB) and IMU logger for wave detection, a handful of GPS drifters to mark instruments, and 4 timelapse cameras to document surface changes. All instruments performed as expected, except one S1000 ADCP that failed due to power issues. All but three instruments (one OpenMetBuoy, one SVP, and one IMB) were recovered before leaving the study area on 30 July. The processed data will be provided and linked to when available.

    Description: During Polarstern expedition PS131 (ATWAICE: ATlantic WAter pathways to the ICE), a large number of autonomous instruments were installed on three representative ice floes across the marginal ice zone northwest of Svalbard in July 2022. The aim was to investigate sea ice summer melt processes, with a focus on the contribution of the Atlantic water inflow into the region. The attached .zip file includes raw data files obtained from all instruments deployed on the southernmost floe, also referred to as Floe South. Depending on the instrument, the data were transmitted via satellite, collected on internal memory, or both. The instruments were installed on Floe South on 14 July 2022, revisited for maintenance on 21 July 2022, and partially recovered on 31 July 2022. The sensors included 1 ADCP to measure ocean currents, a CTD buoy (SIT) with 5 SBE37IMP, a SIMBA- and a SIMB-type ice mass balance buoy to determine ice surface and bottom melt, an OpenMetBuoy (OMB) and iridium IMU logger for wave detection, two GPS drifters, and 2 timelapse cameras to document surface changes. All instruments performed as expected. All instruments except one OpenMetBuoy were recovered before leaving the study area on 31 July. The processed data will be provided and linked to when available.
