Benthic foraminifera of sediment core AMD15-CASQ1-BC

Rebecca Jackson
Includes fluxes of planktonic and benthic foraminifera, the flux of foraminifera organic linings and % of agglutinated taxa. Relative abundance (%) of all taxa counted in the >63µm fraction after wet-sieving. Counting was done on wet samples, stored in buffering solution. Foraminifera species attributed to chilled Atlantic or Polar/Arctic groups can be found in Table 2 of the related paper.

High resolution radiosonde measurements from station Ny-Ålesund (2021-10)

Marion Maturilli
At AWIPEV research base in Ny-Ålesund, Svalbard, regular radiosonde launches are operated once per day. The launch frequency may increase to 6-hourly soundings during specific campaign periods. The Vaisala RS41-SGP radiosondes provide data of pressure, temperature, relative humidity, wind speed and wind direction from ground to about 30 km height. The given data set contains vertical profiles with 1-second time resolution data as obtained by the manufacturer's data processing, quality controlled for appropriate physical ranges.

Airborne sea ice parameters during aircraft flight P5_205_PAMARCMIP_2017_1704041501, Version 1

Arttu Jutila, Stefan Hendricks, Robert Ricker, Luisa von Albedyll & Christian Haas
Airborne multi-instrument measurements of sea ice were made in April 2017 as part of the Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMIP) under the AWI IceBird campaign series. The data consist of four surveys spanning sea-ice covered areas in the Beaufort and Chukchi Seas. For each flight, the geolocated total (ice+snow) thickness data from an airborne electromagnetic (EM) induction sensor are provided with a point spacing of approximately 5-6 meters. Larger...

Effect and fate study with blue mussels and microplastic in a laboratory experiment: fate experiment

Aurelia Laubscher, Thea Hamm & Mark Lenz
Adult blue mussels (Mytilus spp.) were exposed to microplastic particles in a controlled laboratory experiment. The fate of PS beads within the experimental set up was assessed in four compartments (exposure water, depuration water, feces, softbody) after 2 hours of exposure, 24 hours and 48 hours of depuration in filtered sea water. Additionally, the loss of microplastic as the difference of the sum of all recovered PS beads and the measured concentration at the start...

Ocean Floor Observation and Bathymetry System (OFOBS) seafloor images of the Weddell Sea, Antarctica collected during the PS124 Polarstern expedition

Autun Purser, Laura Hehemann, Lilian Boehringer, Ellen Werner & Frank Wenzhöfer
During the RV POLARSTERN expedition PS124 to the Weddell Sea during Jan - April 2021 the Ocean Floor Observation and Bathymetry System (OFOBS) was used to collect still and video images, as well as sidescan data, from various locations surveyed during the research cruise.In this data set ~11,700 seafloor Images from 16 deployments made across the Filchner Shelf, Filchner Sill and Weddell Sea seafloor are presented.The OFOBS system consisted of a towed underwater camera system...

Niche differentiation of sulfur-oxidizing bacteria (SUP05) in submarine hydrothermal plumes

Bledina Dede & Anke Meyerdierks
Chemistry and microbial cell numbers of two bathy- (Brothers volcano; BrV-cone and northwest caldera; NWC) and a mesopelagic (Macauley volcano; McV) plumes on the Kermadec intra-oceanic arc in the South Pacific Ocean. The microbial cell numbers were determined using Catalyzed reporter deposition fluorescence in situ hybridization (CARD-FISH). Chemical measurements of DFe, DOC, TDN, PO4, NOx and SPE-DOC in the plumes are given.

Term-day magnetic observations from the Prague-Clementinum observatory on 1843-03-23

Pavel Hejda, Miloš Revallo & Fridrich Valach
Data of term-day observations recorded at the Prague-Clementinum observatory in years 1840-1849 are presented. The data were obtained by digitising and processing the original old records published in the yearbooks of this historical observatory. The term-day observations had been agreed for joint measurements by the observatories organised in the Göttingen Magnetic Union (GMU). Data of 120 term-days from January 1840 to December 1849 are published. The observations started at 10 p.m. of Göttingen Mean Time...
