title: Mass estimates and morphometric meassurements of Discoaster species and Sphenolithus from Ceara Rise ODP Site 927

description: Mass estimates for Late Miocene and Pliocene (8.6-3.25 Ma) Discoaster species and Sphenolithus are determined using samples of the equatorial Atlantic (Ceara Rise: ODP Site 927). Based on morphometric measurements, 3D computer models were created for 11 Discoaster species and their volumes calculated. From these, shape factors (ks) were derived to allow calculation of mass for different-sized discoasters and Sphenolithus abies. The mass estimates were then used to calculate the contribution of nannofossils to the total nannofossil carbonate. The discoaster contribution ranges from 10% to 40%, with a decreasing trend through the investigated interval. However, our estimates of total nannofossil carbonate from size-corrected abundance data are consistently 30-50% lower than estimates from grain-size measurement; this suggests that data based on mass estimates need to be interpreted with caution.

title: Water isotope values in shore samples collected in March and July 2020 from northeastern German lake systems

description: Water isotopes (δ2H and δ18O) were analyzed in samples collected in lakes associated to major riverine systems in northeastern Germany throughout 2020. This sub-dataset is derived from water samples collected from lake shores. Samples were taken in March and July 2020 with a pipette from 40-60 cm depth below water surface and directly transferred into a measurement vial. Stable isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. The data give information about the seasonal isotope amplitude in the sampled lakes and about spatial isotope variability in different branches of the associated riverine systems.

title: Visual images of the surface taken by a camera installed on RV POLARSTERN during expedition PS131 (ATWAICE) (June - August 2022, Fram Strait/East Greenland)

description: During the Polarstern cruise PS131 photos of the surface (open ocean and sea ice) were recorded from onboard the vessel with a down-looking camera (GoPro Hero 9 Black) that was installed on starboard on the upper deck (at around 21.5 m from sea level ('Peildeck')). The viewing angle (off-nadir) was around 70°. Each image has a size of 5184 × 3888 pixels. The images are stored as zipped JPG files where one zip file includes data from one hour. The visual camera was operated in conjunction with an infrared camera, pointing at the same target, in addition, microwave radiometers measured the surface brightness temperatures of a small area within the camera image. From 11 July, 00:52 UTC, the cameras was operated with a sampling rate of 0.2 Hz, taking a picture every 5 s. Data is missing from 17 July, 8:52 to 18 July, 7:05, on 25 July from 16:55 - 18:13, from 31 July, 10:16 to 1 August, 10:52, and from 2 August, 8:20 to 3 August, 9:42.The images contain open ocean as well as sea ice in the eastern Fram Strait, the marginal ice zone in Fram Strait, during the transit to the Aurora vent field (high ice concentration) and near East Greenland (fast ice).
description: File descriptions: Zip files with JPG files. Metadata of the JPG files includes GPS date/time which was used to name the file according to the date and time. For cases with no GPS data (marked by ending with no_GPSdata.JPG) the time in the name of the file is taken from the internal camera timestamp which may deviate from the GPS timestamp by up to 4 seconds. internal software issues falsely shifted the timestamp of every 12th image by 1 minute in cases with no GPS which was confirmed by visual inspection and corrected during the naming of the files. The filename therefore contains the corrected timestamp .

title: Water isotope values in time series samples (March - October 2020) collected at buoys deployed in northeastern German lake systems

description: Water isotopes (δ2H and δ18O) were analyzed in samples collected in lakes associated to major riverine systems in northeastern Germany throughout 2020. This sub-dataset is derived from water samples taken at buoys temporarily installed in deep parts of the lake. Samples were taken monthly to bimonthly from March to October 2020. A Limnos water sampler was used to obtain samples from 1 m below water surface. Isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Water temperatures were measured in similar depths with an Aqua TROLL 600 multiparameter sonde (In-Situ, Fort Collins, CO, USA). The data give information about the seasonal isotope amplitude in the sampled lakes and about spatial isotope variability in different branches of the associated riverine systems.

title: Relative abundances of coccolith species in surface sediment samples from Polarstern expedition PS97

description: This dataset includes the relative abundances of coccolith species identified with a scanning electron microscope from surface sediment samples samples with a Multicorer during Polarstern Expedition PS97 (Lamy, 2016, doi:10.2312/BZPM_0701_2016), extending from the southern Chilean Margin towards the south across the Drake Passage. The uppermost centimetre of the multicores were sampled and prepared with a combined dilution/filtering technique following Andruleit (1996) doi:10.2307/1485964. Between 66 and 153 mg of dry bulk sediment per sample were suspended in demineralized water buffered with ammonia and ultrasonicated for up to 30 s. The suspensions were split to one-hundredth with a rotary sample divider, filtered through polycarbonate membrane filters with a pore size of 0.45 μm, and dried in an oven at 40 °C for 24 h. Out of the dried filters, a piece of approximately 1 cm² was cut out, mounted on an aluminium scanning electron microscope (SEM) stub, fixed with carbon conductive tabs and sputter-coated with gold-palladium. The filters were analysed with a Zeiss DSM 940A SEM at a magnification of 3000x. A minimum of 300 coccoliths per sample was counted in transects across the filter area, except for 5 relatively coccolith-poor samples south of the PF and one in the SAZ in which at least 100 coccoliths were counted. Datings of near-surface sediments at the southern Chilenean margin (Caniupán et al., 2011b, doi:10.1029/2010PA002049) as well as south of the PF within the DP (Vorrath et al., 2019, doi:10.1594/PANGAEA.897163) give calibrated accelerator mass spectrometry (AMS) 14C ages of 2.91 – 3.06 kyr BP and 4.83 kyr BP respectively. We therefore assume that our studied surface sediments represent relatively modern conditions, with ages ranging most likely from mid to late Holocene. Counting of coccoliths took place in 2020 in order to assess the recent to (sub-) fossil record of coccolithophores in the Drake Passage in the Southern Ocean.

title: Airborne sea ice parameters during aircraft flight P6_217_ICEBIRD_2019_1904020901, Version 2

description: Airborne multi-instrument measurements of sea ice were made in April 2019 during the winter campaign of the AWI IceBird campaign series. The data consist of five surveys spanning sea-ice covered areas in the Lincoln Sea, Central Arctic Ocean, as well as the Beaufort Sea. 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 gaps in the trajectories arise from high-altitude calibrations of the EM sensor. The data are combined with collocated and simultaneous snow depth measurements from an airborne frequency-modulated continuous-wave ultrawideband radar, snow freeboard measurements from an airborne near-infrared laser scanner, and surface temperature measurements from an airborne infrared radiation pyrometer. Each value represents the average within the approximately 40 m diameter footprint of the EM sensor, thus representing a smoothed representation. These values are then used to derive further sea ice parameters such as sea ice bulk density. The trajectory data contain the full and unfiltered data record with quality flags.
