title: Biochemical investigation of multicorer sediment profile PS93/051-4

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: Raw physical oceanography, ocean current velocity, bio-optical and biogeochemical data from mooring HG-EGC-5 in the Fram Strait, July 2018 - August 2019

description: Time-series data of physical & biological oceanography, nutrient biogeochemistry, molecular biology and carbon/particle export were obtained from mooring HG-EGC-5 in the Fram Strait in July 2018 - August 2019 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 PS114, and recovered during PS121. The attached archive contains raw data files of three Seabird SBE37 microcats (nominal depths: 72m, 241m, 508m; sampling interval 1h), three AADI RCM11 current meters (nominal depths: 79m, 248m, 511m; sampling interval 1h), one AADI Seaguard current meter (nominal depth: 987m, sampling interval 1h), one Wetlabs ECO PAR sensor (nominal depth: 72m; sampling interval 1h), one Wetlabs ECO Triplet fluorometer (nominal depth: 72m; sampling interval 2h), two Satlantics SUNA nitrate sensors (nominal depths: 72m, 241m; sampling interval 4h), one Sunburst SAMI-pCO2 sensor (nominal depth: 241m; sampling interval 1h) and two Sunburst SAMI-pH sensors (nominal depths: 72m, 241m; sampling interval 3h). One Sunburst SAMI-pCO2 sensor (72m) was flooded and all data was lost. The mooring also included two McLane RAS water samplers (nominal depths: 72m, 241m) and one sediment trap (nominal depth: 504m). Auxiliary information such as sensor calibration sheets, mooring diagrams and schedule files are also provided, if applicable.
description: The file HG-EGC-5.zip includes all available sensor raw data from mooring HG-EGC-5. The structure of the unzipped folders is mooring-&gt;sensor/sampler type-&gt;serial number-&gt;instrument files. All instruments were synched to UTC before deployment, and the offset after the recovery is supplied in the respective instrument folder, if available.

title: Raw data of physical oceanography during RV MARIA S. MERIAN cruise MSM93

description: Raw physical oceanography data were acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard Maria S. Merian during research cruise MSM93 to the Fram Strait. In total, 51 hydrographic profiles were acquired as part of 4 main CTD transects, and bottle samples were taken during 44 casts. The installed sensor suite provided duplicate measurements of seawater temperature (SeaBird SBE3plus), conductivity/salinity (SeaBird SBE4) and dissolved oxygen (SeaBird SBE43), along with pressure/depth (SeaBird SBE9), Chl-a fluorescence and turbidity (Wetlabs ECO-FL-NTU), and PAR within the water column. Additionally, a surface PAR sensor was installed on the ship as a reference. Individual sensor pairs suffered from data quality issues throughout most of the campaign, especially in the upper 40 m. In all affected profiles, the duplicate sensor pair was still giving reliable data. The installed PAR did not provide any data.

title: Pollen profile, BHY III: overlying stone-wall field system in Behy townland, Céide Fields

description: The sampling sites BHY III–VI are from within the stone wall field system that is covered by blanket bog. BHY III is from ca. 65 m west of Behy Court Tomb. There was fairly active peat cutting locally, but on a rather small scale prior to time of sampling (1992). There has been turf cutting since, especially immediately to the west of this site.A monolith was removed as follows: 71 cm long (11 cm of mineral soil; 61 cm of overlying peat; total depth of peat, adjusted for shrinkage, at sampling point (TDP): 130 cm].This was taken from long turf bank where there was a wide cutting (ca. 30 m to next bank of turf to the east). At 30 cm from the sampling point, a flat pine timber (1x6 cm; probably a root) partly projected from the base of the turf bank. The wood rested on 10-15 cm of peat and its outer surface was burned. No other pine stumps were noted in the long bank of turf but there are pine stumps in the general area. A few metres to south of sampling location, there is a substantial stone cross-wall of a pre-bog field.The pollen and macrofossil investigations were carried out by Karen Molloy. LOI and tephra investigations were also carried out. BHY III is the only profile of BHY series in which no tephra was recorded.The age/depth curve (obtained using Clam v. 2.2; details are provided) for BHY III is a smooth spline curve (smooth factor = 0.3) that is based on five of the available seven 14C dates. The 14C dates 3360±50 BP (Gd-7147) and 3290±60 BP (Gd-7148) (both relate to peat from -6 to -7 cm) (both dates regarded as unreliable) were not included in the analysis.A distinct 'pine flush' is recorded at the base. The age/depth model indicates that this dates to ca. 2600 BC which, based on other dates relating to pine in the region, is probably at least two centuries too young (O'Connell et al. 2019). A pronounced Betula to Poaceae switch occurs at ca. 1500 BC. These investigations relating to Céide Fields were carried out in PRU, NUIG, part-funded by The Heritage Council (of Ireland). The aim was to provide an environmental context for the establishment and use of the prehistoric stone-wall field system, and an overall chronological framework and an environmental history of the area.

title: Effects of Atlantification and changing sea-ice dynamics on zooplankton community structure and carbon flux between 2000 and 2016 in the eastern Fram Strait

description: The collection of zooplankton swimmers and sinkers in time-series sediment traps provides a unique insight into year-round and inter-annual trends in zooplankton population dynamics. Such samples are particularly valuable in remote and difficult to access areas such as the Arctic Ocean, where samples from the ice-covered seasons are rare. In the present study, we investigated zooplankton composition based on swimmers and sinkers collected by sediment traps at water depths of 180-280 m, 800-1320 m, and 2320-2550 m, over a period of 16 years (2000-2016) at the central station of the LTER (Long-Term Ecological Research) HAUSGARTEN observatory in the Fram Strait. The time-series data include the abundance of copepoda, foraminifera, ostracoda, amphipoda, pteropoda, and chaetognatha that were collected in the sediment trap time-series.

description: During PS85 (in 2014) taxa specific macrofauna density was determined. Sediment from MUC recovered sediment cores and from the benthic chambers was used for macrofauna taxonomical identification and density determination. For these macrofauna analyses only the 0-5 cm horizon from MUC sediment cores and the entire sediment from the benthic chambers was used, sieved over a 500 µm mesh and stored in borax buffered 4 % formaldehyde and stained with Rose Bengal (Heip et al., 1985). Afterwards, macrofauna taxa were identified to the highest taxonomic level and counted.

title: Processed monthly mean data from regular measurements of air temperature, relative humidity, and precipitation at a climate observatory (station) from 1899 to 2024, in Stara Zagora, Bulgaria

description: Stara Zagora station, Bulgaria (coordinates: latitude/longitude: 42.386759°N/25.647005°E, altitude 168 m), is part of the climate network of 32 stations across the country, managed by Bulgaria's National Institute of Meteorology and Hydrology (NIMH). NIMH has an agreement with the local Thracian University, which uses part of the university's base on the outskirts of Stara Zagora for the local climate station. According to the agreement, the station regularly provides meteorological information to interested researchers from the university. The station provides the university with the following data: 1. Air temperature in degrees Celsius, measured in a meteorological cell 2 m above the ground surface - daily values and monthly average; 2. Relative humidity in %, measured in a meteorological cell 2 m above the ground surface – daily values and monthly average; 3. Precipitation in mm (l/m2) – measured with a rain gauge, daily values, and monthly sum. This information was used for research about global warming, and annual values were additionally calculated.
