title: Images of pelagic organisms observed by PELAGIOS during Maria S. Merian cruise MSM49

description: The video that was collected in November and December 2015 during horizontal transects with the PELAGIOS towed camera system during cruise MSM49 in waters around Cabo Verde in the eastern tropical north Atlantic was annotated using the video and annotation reference system (VARS) developed by the Monterey Bay Aquarium Research Institute. In total more than 40 hours of video were collected and annotated, and 43 taxonomic groups were annotated, mostly consisting of gelatinous zooplankton. This resulted in a dataset of diversity and abundance data from which vertical distribution, abundance and diversity of pelagic fauna could be derived (https://doi.pangaea.de/10.1594/PANGAEA.919333). This dataset provides examples of images of annotated organisms.

title: Nitrogen isotope ratio and oxygen isotope ratio from Arabian Sea IODP Site 355-U1456

description: Denitrification in the Arabian Sea is closely related to the monsoon-induced upwelling and subsequent phytoplankton production in the surface water. The δ15N values of bulk sediments collected at Site U1456 of the International Ocean Discovery Program (IODP) Expedition 355 reveal the orbital-scale denitrification history in response to the Indian Monsoon. Age reconstruction based on the correlation of planktonic foraminifera (Globigerinoides ruber) δ18O values with the LR04 stack together with the shipboard biostratigraphic and paleomagnetic data assigns the study interval to be 1.2 Ma. Comparison of δ15N values during the last 800 kyrs between Site U1456 (Eastern Arabian Sea) and Site 722B (Western Arabian Sea) showed that δ15N values were high during interglacial periods, indicating intensified denitrification, while the opposite was observed during glacial periods. Taking 6‰ as the empirical threshold of denitrification, the Eastern Arabian Sea has experienced a persistent oxygen minimum zone (OMZ) to maintain strong denitrification whereas the Western Arabian Sea has undergone OMZ breakdown during some glacial periods. The results of this study also suggests that five principal oceanographic conditions were changed in response to the Indian Monsoon following the interglacial and glacial cycles, which controls the degree of denitrification in the Arabian Sea.

title: Benthic sulfate reduction rates traversing the Peruvian oxygen minimum zone (12°S)

description: Sediment samples were taken during May 2017 on research vessel (R/V) Meteor (M137) at four stations (74, 128, 243, and 752 m) along the 12º S depth transect traversing the Peruvian OMZ. Samples were retrieved using a TV-guided multicorer (MUC) equipped with seven core liners as described previously. Core liners were 60 cm long with an inner diameter of 10 cm. Filaments of giant sulfur oxidizing bacteria were observable by eye at the sediment surface (dense mat) and inside sediment at the 128 and 243 m stations. Filaments were detected mostly inside sediment at the 74 m station and were not observed at the 752 m station. Retrieved cores were immediately transferred to cold rooms (12ºC) for further processing. At each station, two small push cores (length 20 cm, inner diameter 2.6 cm) were subsampled from one MUC core. One of the replicate sub-cores (hereafter 'spiked core') was amended with unlabeled sulfide: 16 µl saturated sulfide solution (2.42 M stock solution: 250 g Na2S • 9 H2O in 420 ml ultrapure water) was injected into the sediment push core through pre-drilled holes placed at 1 cm depth increments following the principle of the whole-round core injection method. Based on an average sediment water content of ~80%, the added sulfide resulted in a final sulfide concentration of 10 mM in the porewater after its dilution into the sediment (5 cm3 sediment per injection point). The second sub-core remained untreated (hereafter 'unspiked core'). After an equilibration for 1-2 hrs at 12ºC in the dark, 10 μL of carrier-free 35S-sulfate radiotracer (dissolved in water, 1.86 MBq, specific activity 37 TBq mmol-1) was injected into both sub-cores at 1 cm depth increments according to the whole-core injection method. In the spiked core, radiotracer was injected through the same ports used for sulfide injection. Both spiked and unspiked cores were incubated with radiotracer for 6-8 hrs at 12ºC in the dark. After incubation, bacterial activity was stopped by slicing sub-cores at 1 cm increments and transferring sediment layers into 50 mL plastic centrifuge tubes filled with 20 mL zinc acetate (20 % w/w). Triplicate 'killed' controls were produced from additional sediment of the same MUC core and microbial activity was first terminated with zinc acetate before the addition of radiotracer to the centrifuge vial. All samples were frozen at -20ºC until analysis, when sulfate reduction rates were determined following the cold chromium distillation procedure.

title: Concentrations and stable isotopic composition of particulate organic carbon and nitrogen from water column samples collected in the central Arctic Ocean in 2019/2020 during the MOSAiC campaign

description: Concentrations and stable isotopic composition of particulate organic carbon and nitrogen from CTD-rosette casts during the MOSAiC (PS122) drift expedition in the central Arctic Ocean (see Fong et al. 2024 for details). 2-10 L of water were filtered onto precombusted GF/F filters (nominal pore size 0.7 µm) and frozen at -20°C. All samples were freeze dried. Samples for measurements of δ13C values, %C and %N were acidified by contact with HCl fumes for 4 h in a vacuum-enclosed system to remove carbonates, while samples for N stable isotope analysis were analyzed raw. Samples were analyzed using a continuous flow isotope ratio mass spectrometer (Delta V Plus with a Conflo IV interface, Thermo Scientific) interfaced with an elemental analyser (EA Isolink, Thermo Scientific) at the Littoral, Environment and Societies Joint Research Unit stable isotope facility (CNRS - University of La Rochelle, France). Normalization was done using reference materials (USGS61 and USG63, US Geological Survey). A subset of 28 dried and acidified samples was analyzed at AWI for POC and PON concentrations only, using a using a CHNS-O elemental analyzer (Euro EA 3000, HEKAtech) with acetanilide as a calibration standard.

title: Whale sightings during POLARSTERN cruise PS143/2

description: Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS143/2 (Tromsø – Tromsø) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a "certainty" level of identification. The number of animals were counted if possible or estimated for larger groups. Whenever identification to species level was not possible, the next identifiable taxonomical category was assigned. Information on sighting position, date and time are automatically transferred from the ship's DAVIS-Ship System (https://dship.awi.de/) to the WALOG software at the time of logging. Photographs were taken, if possible, for retrospective analysis. All data of acquired sightings were retrospectively validated by a marine biologist and converted to a standard format. To this end, plausibility of sighting time, location, standardization of species names, eventual comments added at the time of sighting, as well as additional information such as photographs (if available) were checked either to verify or improve species identification. Datasets are used in species distribution modelling and to inform interested parties about occurrences.
description: Date/Time is given in UTC. Certainty of identification: definite if observer clearly identified the species. The number of individuals is binned according to the options given in the data acquisition software: 1, 2, 3, less equal 5, less equal 10, greater than 10, greater than 20. More precise values may exist, due to observer comments.

title: Basic measurements of radiation at station Granite Island (2025-03)

description: No DIF, DIR, SWD and LWD data March 1,2,5,6,7,8,9 due to heavy ice build-up on instruments. Backup Temp/RH sensor failed March 9. No RH data will be available from March 9 (when failure occurred) through the end of the month. The data logger panel temperature was used in place of the air temperature measurement from March 9 (when failure occurred) through the end of the month. It was determined through analysis that the panel temperature -2°C can be a reasonable proxy for air temperature. The ventilators (fans) were repaired on March 13 (They failed Feb. 1). DIF and DIR data will not be available on the days the solar tracker was turned off. The solar tracker was turned off March 1-11, March 16-25 and March 31 due to multiple winter storms with potential heavy ice build-up on the instruments. On 2025 March 26, the component summation indicates a possible issue with the DIR measurement primarily from 15-17 GMT.
