title: Physical oceanography from mooring KPO_1200

description: GEOMAR moorings are typically equipped with instruments recording pressure, temperature, conductivity, dissolved oxygen and current velocity. Instruments with pressure, temperature, conductivity and oxygen sensors were calibrated in situ immediately prior to and after a mooring deployment period by attaching them to the CTD frame during CTDO casts. Correction terms were then developed from the difference between the sensor readings and the calibrated CTDO data during several minute long calibration stops. These correction terms were then applied to the full deployment periods. This ensured best data quality with recognition of potential sensor drifts and also allowed for the estimation of calibration and measurement errors (Hahn et al. 2014, Bittig et al. 2018, Berx et al. 2019).

title: LADCP current profiles collected during MedSHIP cruise TAlPro2016

description: This data set contains station data of top-to-bottom oceanic current measurements performed with Lowered Acoustic Doppler Current Profilers (LADCP) during the MedSHIP cruise TAlPro2016 (Palermo - Barcelona, RV Angeles Alvariño, 18/-8/2016 - 29/08/2-16). The LADCP devices in use were a downward and an upward-looking ADCP of type Teledyne RDI Workhorse Monitor 300 kHz. Station data of zonal and meridional oceanic velocities are reported in [cm/s] on a 10 m vertical grid. The processing of the data has been done using the LDEO LADCP data processing software (https://www.go-ship.org/Manual/Thurnherr_LADCP.pdf)

title: Whale sightings during POLARSTERN cruise PS110 (ANT-XXXIII/1)

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 PS110 (Bremerhaven – Cape Town) 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: Radium isotopes and 228Th in surface water samples collected on POLARSTERN expedition PS78

description: 228Ra is strongly enriched in shelf waters and its half-life (5.8 years) is well suited to study the fate of shelf-derived water in the central Arctic. During PS78 (TRANSARC I) we studied the distribution of 228Ra in surface waters of the central Arctic to investigate how this 228Ra signal is transported in the Transpolar Drift. Water from the ships' seawater intake (Sta 196, 205) or from a submersible pump lowered to 10m depth on hydrographic stations (from station 209 onwards) was filtered and passed over MnO2-coated cartridges to absorb Radium and Thorium. Short-lived 224Ra, as analog for the total concentration of its parent 228Th, was determined on board with RaDeCC counting. In the lab, the cartridges were leached and long-lived Radium isotopes were measured by gamma spectroscopy.

title: Aerosol chemical composition (major ions and iodine species) in samples collected during the M138 cruise in the eastern Pacific Ocean, June 2017

description: Size segregated aerosol samples were collected during the M138 cruise (FS Meteor) during 6 June - 1 July 2017 in the eastern Pacific Ocean (~86 W - 76 W, 16 S – 5 N). The samples were collected by Hermann Bange of GEOMAR, Kiel, Germany. The aerosol sampler was situated on the roof of the ship's wheelhouse and its operation was controlled by an automatic wind sector controller to prevent contamination from the ship's stack. Samples were collected using a Sierra-type cascade impactor to separate the aerosol particles at an aerodynamic diameter cutoff of 1 µm. Collection time for these samples varied between 14.3 and 65.2 hours. Samples were extracted with ultrapure water and the major ions Na+, NH4+, Mg2+, K+, Ca2+, Cl-, NO3-, SO42-, oxalate, Br- and methanesulfonate were determined by ion chromatography (IC). Total soluble iodine (TSI) was determined by inductively coupled plasma - mass spectrometry (ICP-MS) and iodide (I-) and iodate (IO3-) were determined by IC-ICP-MS. Analysis work was performed by Andrew Smith of University of East Anglia, Norwich, UK. The dataset contains the atmospheric concentrations of all measured soluble major ions (in nmol/m³)) and iodine species (in in pmol/m³). The data are reported in “Soluble iodine speciation in marine aerosols across the Indian and Pacific Ocean basins”, E. Droste et al., Frontiers in Marine Science, in preparation, (2021).

title: Heat flow data at station HF1620 during RV SONNE cruise SO247

description: We used the 6 m long Bremen heat flow probe also called Giant Heat Flow Probe (GHF). The heat probe is constructed in the classical “violin bow” design (Hyndman et al., 1979; Hartmann and Villinger, 2002, Villinger et al., 2010), with 21 thermistors distributed over an active length of 5.2 m in 0.26 m intervals mounted inside an oil filled hydraulic tube (O.D. 14 mm) which is attached to the strength member (O.D. 130 mm). The sensor tube also contains a heater wire for the generation of high energy heat pulses of typically on the order of 800 J/m for in situ thermal conductivity measurements according to the pulsed needle probe method (Lister, 1979). A calibrated PT-100 seawater sensor on top of the weight stand allows to measure the absolute bottom water temperature and to check the calibration of the sensor string in deep water with high accuracy. Inclination and acceleration of the probe is measured to monitor the penetration process into the sediments and potential disturbances during the actual measurement period.
