title: Acidity measured with the Electrical Conductivity Method (ECM) on the full EGRIP ice core, converted to hydrogen ion concentration

description: ECM data of the East GReenland Ice core Project (EGRIP) core with the technique described by Hammer (1980) was recorded in the field during the 2017, 2018, 2019, 2022, and 2023 field seasons. The resolution of ECM data is 1 mm. The data is given as H+ ion concentration, but the absolute calibration must be considered tentative. The data set is an extension of the data presented in Mojtabavi et al., 2020, and all details regarding data processing etc. can be found therein.

title: Biochemical investigation of multicorer sediment profile PS99/041-9

description: To detect and track the impact of large-scale environmental changes in a the transition zone between the northern North Atlantic and the central Arctic Ocean, and to determine experimentally the factors controlling deep-sea biodiversity, the Alfred- Wegener-Institute for Polar and Marine Research (AWI) established the deep-sea long-term observatory HAUSGARTEN, which constitutes the first, and until now only open-ocean long-term station in a polar region. Virtually undisturbed sediment samples have been taken using a video-guided multiple corer (MUC) at 13 HAUSGARTEN stations along a bathymetric (1,000 - 4,000 m water depth) and a latitudinal transect in 2,500 m water depth as well as two stations at 230 and 1,200 m water depth within the framework of the KONGHAU project. Various biogenic sediment compounds were analyzed to estimate the input of organic matter from phytodetritus sedimentation, benthic activities (e.g. bacterial exoenzymatic activity), and the total biomass of the smallest sediment-inhabiting organisms (size range: bacteria to meiofauna).

title: Ex situ measured oxygen profiles from station PS85/445-1 (EG III) within the HAUSGARTEN area (Fram Strait) in 2014 (POLARSTERN cruise PS85)

description: During PS85 (in 2014) and PS93.2 (in 2015) sediment cores were recovered by a Multiple corer. Sediment cores were stored at in situ temperature of -0.75°C and used to measure oxygen profiles across the sediment-water interface with needle type optodes (diameter: 50µm, Pyro Science). By using the profiles, the diffusive oxygen uptake was calculated via the decrease in the oxygen concentration in the Diffusive Boundary Layer (DBL). For a further description of the calculation, please check the related publication.

title: Organic matter and phytoplankton measurements of POLARSTERN cruise PS114

description: The discrete biogeochemical measurements from RV Polarstern PS114 sampled for organic matter, primary production and phytoplankton abundances. The parameters include POC, phytoplankton abundances and production. The samples were acquired within 0-100 m of the Greenland Sea between 78°N to 80°N and 3°E to 10°E. The data was collected daily on board PS114 from 16th July 2018-23rd July 2018 . The water collection occurred using a CTD and laboratory methods varied by parameter. POC was analyzed using a EURO EA CHNS-O Elemental Analyzer, carbohydrates were analyzed using High performance anion exchange chromatography with pulsed amperometric detection, amino acids were analyzed using High Performance Liquid Chromatography (HPLC) ortho-phthaldialdehyde derivatization, rates of primary production (PP) were measured in situ using the 14C method and subsampled as total PP (PP-TOC), particulate PP (PP-POC), and dissolved PP (PP-DOC), cell abundances were measured using orange and red autofluorescence detected by flow cytometry. The purpose of data collection was to understand seasonal cycling of organic mater.

title: Raw physical oceanography and ocean current velocity data from mooring HG-IV-FEVI-42 in the Fram Strait, June 2021 – July 2022

description: Time-series data of physical oceanography, ocean current velocities and carbon/particle export were obtained from mooring HG-IV-FEVI-42 in the Fram Strait from June 2021 to July 2022 as part of the Helmholtz infrastructure program Frontiers in Arctic Marine Monitoring (FRAM) and the long-term monitoring program at AWI HAUSGARTEN. The mooring was deployed during RV POLARSTERN expedition PS126 and recovered during PS131. The attached archive contains raw data files of five Seabird SBE37 MicroCATs (nominal depths: 75m, 248m, 400m, 1200m, 2530m; sampling interval 1h), four Seabird SBE56 temperature loggers (nominal depths: 100m, 150m, 200m, 325m; sampling interval 60s), one Nortek Aquadopp current meter (nominal depth: 750m; sampling interval 20 min), one RDI Longranger ADCP (nominal depth: 404m; sampling interval 1h), three AADI Seaguard current meter (nominal depths: 198m, 1235m, 2348m; sampling interval 1h) and one AADI RCM11 current meter (nominal depth: 2524m; sampling interval 1h). The mooring also included three sediment traps (nominal depths: 191m, 1228m, 2341m; data archived elsewhere) and four PE samplers (nominal depths: 198m, 415m, 1178m, 2532m; data archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable.

title: Raw data of physical oceanography during RV POLARSTERN cruise PS126

description: Raw physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV Polarstern during research cruise PS126. The CTD was equipped with duplicate sensors for temperature (SBE3plus), conductivity (SBE4) and oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer (FLRTD) and an altimeter (Teledyne Benthos PSA-916) were mounted to the CTD. The data was recorded using pre-cruise calibration coefficients. No correction, post-cruise calibration or quality control was applied. All sensors performed generally fine, except during one cast (PS126_23-8) where the secondary oxygen sensor had issues below 4000m. For more details see cruise report linked below. A PDF with scans of the handwritten protocols is included in this publication. The processed dataset will be linked below upon completion.

title: Raw data of physical oceanography during RV POLARSTERN cruise PS131

description: Raw physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV POLARSTERN during research cruise PS131 (ATWAICE: ATlantic WAter pathways to the ICE). The CTD was equipped with duplicate sensors for temperature (SBE3plus), conductivity (SBE4) and oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer (FLRTD), a CDOM WET Labs ECO-FL fluorometer (FLRTD), a PAR sensor (SeaBird PARLOG) and an altimeter (Teledyne Benthos PSA-916) were mounted to the CTD. The data was recorded using pre-cruise calibration coefficients. No correction, post-cruise calibration or quality control was applied. For the Aurora cast (PS131_075_01), the PAR sensor was removed to include a Seapoint Turbidity Sensor to facilitate the detection of hydrothermal plumes. Independent sensors such as an Underwater Vision Profiler (UVP5 DEEP) and a Lowered ADCP system (RDI LADCP) were attached to the CTD-Rosette system and operated during most of the casts. For all casts shallower than 2000 m a nitrate sensor (Satlantic SUNA) was attached. For data availability see cruise report. A PDF with scans of the handwritten protocols is included in this publication as zip file. The processed dataset will be linked below upon completion.
description: For a total of 4 stations, casts were numbered differently from the ship's official ActionLog. We kept the original numbering here to avoid further confusion.

description: During PS85 (in 2014) and PS93.2 (in 2015) sediment cores were recovered by a Multiple corer. A sodium bromide solution of similar density as seawater (1028 g/L) replaced the overlying water of the cores. Three subsamples of water were taken during an incubation at three different times (t0, t1, t2) and stored at 4 °C. Removed water volume of the subsampling at t1 was replaced with the NaBr-seawater solution. The bromide concentrations were measured using ion chromatography. The dilution of the t2-sample, due to the sampling procedure, was corrected by the known bromide concentration in the removed and the added water. The solute exchange is represented by the bromide flux
