title: Dissolved and soluble pore water trace metals (Mn, Fe, Co, Ni) from sediment core SO268/2_106-1 (MUC-22) during SONNE cruise SO268/2, central Pacific

description: Physical and chemical trace metal speciation are important for our understanding of metal cycling and potential toxicity to marine life. Trace metals can have different bioavailability and behave differently in diffusion processes or particle-solution interactions depending on their physical and chemical forms. Here we investigated dissolved (&lt; 0.2 µm) and soluble (&lt; 0.02 µm) concentrations of Mn, Fe, Co, and Ni in oxic deep-sea sediments of the central equatorial Pacific. The colloidal fraction (&gt; 0.02 µm &lt; 0.2 µm) of Mn, Co, and Ni increased with depth in the oxic pore waters and Fe had the largest but variable colloidal pool. Samples were taken during the SO268 cruise to the German and Belgian license areas for polymetallic nodule mining in the Clarion Clipperton Fracture Zone as part of the MiningImpact project. Sediment cores were collected with multicorers (MUC) and ROV push cores (PUC). Pore water was extracted by means of centrifugation and sequential filtration using cleaned polyethersulfone (PES) syringe filters (0.2 µm) and Anopore syringe filters (0.02 µm). Pore water was preserved by acidification to ~ pH 1.8 with concentrated ultrapure HCl. Samples were preconcentrated offline with seaFAST and measured by High Resolution Sector Field Inductively Coupled Plasma-Mass Spectrometry.

title: Rates of sulfate and methane turnover in sediments collected in the Campeche Hydrocarbon Province in the Southern Gulf of Mexico in 2015

description: In the Campeche Hydrocarbon province in the southern Gulf of Mexico, large areas of the seafloor are rich in natural gas and highly viscous crude oil. To understand the influence of these hydrocarbons on porewater geochemistry, we cored sediments from specific sites by gravity coring, multicoring and push coring during Meteor Expedition M114-2 in March 2015.To retrieve rates of sulfate reduction and methane oxidation, onboard we incubated select sediment samples with 35S-Sulfate and 14C-methane radiotracers and analyzed the formation of radiolabeled inorganic reduced sulfur and inorganic carbon.

title: Hourly acoustic presence of bowhead whales (Balaena mysticetus) based on passive acoustic monitoring data from mooring ARKR02-01, recorder SV1091, in Fram Strait from July 2016 to July 2017

description: Presence-absence data on hourly acoustic presence of bowhead whales (Balaena mysticetus) were obtained from passive acoustic monitoring (PAM) data collected by passive acoustic recorder SV1091 of type Sono.Vault (manufactured by develogic GmbH, Hamburg, Germany) at 78° 50.01' N, 000° 00.09' E, mooring ARKR02-01, in Fram Strait. Passive acoustic data were collected as part of the Frontiers in Arctic Marine Monitoring (FRAM) observatory in Fram Strait from July 2016 to July 2017 (recording period) by SV1091 (deployment period from July 2016 to July 2018). The recorder was moored at 806 m depth and scheduled to record continuously at a sample rate of 48,000 Hz. Hourly acoustic presence of bowhead whales was assessed based on automated detections of bowhead whale vocalizations using the LFDCS ('Low-Frequency Detection and Classification System') software (Baumgartner and Mussoline, 2011, https://doi.org/10.1121/1.3562166), using an SNR ('signal-to-noise ratio') threshold of 8 dB and a Mahalanobis distance threshold of 1.5. All automated detections of bowhead whale vocalizations were visually reviewed by a trained analyst on an hourly basis in spectrograms using Raven Pro 1.5 (Bioacoustics Research Program, Cornell Lab of Ornithology, Ithaca, USA; window size: 2.5 min; frequency range: 0-1,300 Hz; spectrogram settings: FFT 1,024, overlap 90 %, Hann window). This table contains information on acoustic presence (indicated by “1”, with at least one verified bowhead whale call present in a given hour) or acoustic absence (indicated by “0”) of bowhead whale vocalizations on an hourly basis for the recording period from July 2016 to July 2017.

title: Borehole temperature measurements at MeBo200 drill site GeoB22605-1, Black Sea

description: Borehole temperature measurements at site GeoB22605-1 were performed with the sea floor drill rig MARUM-MeBo200 during research expedition M142 in November 2017 at the Danube Deep Sea fan in the Black Sea. A platinum resistance sensor integrated in the 1343 Slimhole Memory Acoustic Tool developed by ANTARES Datasystems GmbH was used to measure the temperature of the fluid within the borehole with 103 mm diameter. The temperature range is –20 to +80 °C, the absolute accuracy within the limits of the measuring range is about 1 °C. The resolution of the temperature measurements is about 0.003 °C. Temperatures were logged with a frequency of 0.5 Hz by a memory adapter with an integrated clock that was synchronized with GPS-time. Borehole logging was conducted during trip out of the drill string. When the drilling operation was completed and the drill string was lifted by about 3.5 m the logging string was dropped into the drill string. After landing on the drill bit the logging string together with the drill string were tripped out of borehole. The depth control system of the drill rig was used to calculate the sensor depth with an accuracy of 0.1%.

title: Temperature measurements from radiation station 2019R8

description: Solar radiation over and under sea ice was measured by radiation station 2019R8, an autonomous platform, installed on drifting First-Year-Ice (FYI) in the Arctic Ocean during MOSAiC (Leg 1) 2019/20. The resulting time series describes radiation measurements as a function of place and time between 05 October 2019 and 31 July 2020 in sample intervals of 3 hours. The radiation measurements have been performed with spectral radiometers. All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors, solar irradiance and upward reflected solar irradiance, were mounted on a on a platform about 1 m above the sea ice surface. The third sensor was mounted 0.5 m underneath the sea ice measuring the downward transmitted irradiance. Along with the radiation measurements, this autonomous platform consisted of a 5 m long thermistor chain with sensor spacing of 0.02 m and several other sensor packages, which measured water temperature, pressure and conductivity at hourly intervals. Ecology sensors measured backscatter strength, chlorophyll a and fluorescence of dissolved organic matter at hourly intervals. Oxygen sensors measured relative oxygen air saturation, and water temperature at hourly intervals. In addition, relative snow height was measured at hourly intervals. All times are given in UTC.
description: The data set has been processed and contains quality flags for different kinds for erroneous data. Flag values are the sum of individual error codes. The value of 0 refers to no error. Quality flag, position: The geographic position is flagged +1 if the drift velocity, as derived from the GPS longitude and latitude, exceeds a threshold of 10 deg latitude or 50 deg longitude per time step; +2 if the position exceeds extreme values, such as longitude &gt; 360 deg; +4 if the position is exactly 0.0.
