Concentrations of diatoms and percentages of main ecological groups and species from sediment core AMK-6150 (Norwegian Sea)
No full textThe data set contains micropaleontological data from core AMK-6150 (Norwegian Sea) that covers the last 2900 years. The data include concentrations of diatoms and percentages of main ecological groups and species from core AMK-6150 in relation with core depth and age
Multibeam bathymetry raw data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS151
No full textMultibeam data were collected with RV Polarstern along the route of cruise PS151 and data acquisition was almost continuously monitored during the survey. Multibeam sonar system was Teledyne/Atlas Hydrosweep DS3. SVPs were retrieved from CTD data and synthetic profiles from World Ocean Atlas 23. SVPs were processed with HydrOffice SoundSpeedManager (https://www.hydroffice.org/soundspeed/main) and extended with World Ocean Atlas 23 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA23). SVP data were applied during acquisition. Multibeam data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Teledyne Reson multibeam processing format (.s7k) were recorded with Teledyne PDS software. Raw data files can be processed using software packages like CARIS HIPS/SIPS. For updated vessel configuration files check further details
Ocean Floor Observation and Bathymetry System (OFOBS) seafloor images of the Fram Strait collected during RV POLARSTERN cruise PS126
No full textDuring the RV POLARSTERN cruise PS126 (2021-05-24 to 2021-06-27) to the long-term ecological research station HAUSGARTEN observatory in the Fram Strait the Ocean Floor Observation and Bathymetry System (OFOBS) was used to collect still images from various locations surveyed during the expedition. The OFOBS consisted of a towed underwater camera system equipped with a high-resolution photo-camera (iSiTEC, CANON EOS 5D Mark III). The camera was mounted on a steel frame (140 L x 92 W x 135 H cm), together with two strobe lights, three laser pointers spaced with a distance of 50 cm used to estimate the size of seafloor structures, four LED lights, and a USBL positioning system (Posidonia). An automatic seafloor image was taken every 20 seconds to obtain 'TIMER' stills distributed at regular distances along each of the survey profiles. Additional 'SW_RELEASER' photos were triggered individually when interesting objects appeared in the live feed. During this expedition, no positioning data was available for the OFOBS. Here, image data of 3 OFOBS deployments is presented
Water column raw data (Kongsberg EM712 entire dataset) of RV MARIA S. MERIAN during cruise MSM137
No full textRaw water column data were collected aboard RV MARIA S. MERIAN during cruise MSM137 using a Kongsberg EM 712 multibeam echosounder. The expedition took place during 2025-05-10 – 2025-06-13 from Reykjavik (Iceland) to Reykjavik (Iceland) in the North Atlantic. The aim of M137 was to apply enhanced geophysical methods in order to image and identify sills on a detailed scale. Magmatic intrusions are widespread all over the globe. Recently, the impact of sills and dikes onto sedimentary basins is discussed intensly, e.g. for contact-metamorphism and venting of methane. Even global climate anomalies were recently linked to regional sill emplacements and associated outbursts of methane into the atmosphere. Data were recorded within the Norwegian EEZ including Svalbard. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Data acquisition was done by BGR and CAU, provision of the data is supported by the DAM Project Underway Research Data and published according to the FAIR principles

Relative abundance of planktonic foraminiferal species in sediment core MedSeA-S3 retrieved from the Alboran Sea during the MedSeA Cruise 2013
No full textRelative abundance of planktonic foraminiferal species in MedSeA-S3 sediment core, spanning from 378 to 1995 years of the Common Era, examined under a stereo microscope (size fraction >125um) at least 300 speciments were counted and identified
Agulhas Plateau Composite Pleistocene planktic-benthic stable isotope measurements
No full textReconstructions of vertical stable carbon isotope gradient since 1.55 myr ago from the Agulhas Plateau Composite deep sea sediment core site. Stable isotopes (18O and 13C measured on planktic foraminifera species G. truncatulinoides, n = 3 to 15 shells per sample). Isotope measurements are paired with previously published benthic d18O and d13C data from the sample site to generate gradients
