Master track of SONNE cruise SO287 in 1 sec resolution (zipped, 14.5 MB)
No full textRaw data acquired by position sensors on board RV SONNE during expedition SO287 were processed to receive a validated master track which can be used as reference of further expedition data. During SO287 the motion reference unit Kongsberg SeaTex AS MRU-5 combined with Kongsberg SeaTex AS Seapath 320 and two GPS receivers SAAB MGL-4 were used as navigation sensors. Data were downloaded from DAVIS SHIP data base (https://dship.bsh.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track
Physical oceanography (CTD) during SONNE cruise SO234/2
No full textSeabird 911plus systems equipped with dual temperature-conductivity-oxygen sensors were employed. The systems had a 24-bottle water sampling rosette with 10 l Niskin bottles. Water sampling, processing, and calibration followed GO-SHIP recommendations (Swift, 2010; McTaggart et al., 2010; Uchida et al., 2010) and included the recommended steps Data Conversion, Sensor Time-Alignment, Creation of Bottle Files, Outlier Removal, Pressure Sensor Filtering, Conductivity Cell Thermal Mass Correction, Ship Roll Correction and Deck Offset Correction by Loop Editing, as well as Derivation of Calculated Properties. After these steps, conductivity and oxygen readings were calibrated against values determined with salinometry (see section 4.1.4) and Winkler titration (see section 4.2.1), respectively. Finally, the downcast data was averaged over 1 dbar wide intervals. An independent upcast calibration was used to obtain calibrated CTDO values coincident with the discrete water samples

Fe(II) kinetic data from from water samples during POSEIDON cruise POS533 (AIMAC)
No full textAt each station, seawater was collected for trace metals sampling at 20 m depth using a Teflon pump (Furon®) with a 40 m Teflon tube connected with a AcroPakTM 1500 capsule w/Supor Memb 0.8/0.2 μm filter. The pump was left to pump to rinse the inner hose and 1 L sample was collected in LDPE bottles (NALGENE) and stored at -20oC until the land-based laboratory analysis. The material was previously cleaned following the trace metals GEOTRACES protocol and the experiments were done in Class 100 clean laboratory or trace metal analysis (QUIMA- IOCAG TM lab)

Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO287
No full textMultibeam bathymetry raw data was recorded in the Atlantic during cruise SO287 that took place between 2021-12-11 and 2022-01-11. The data was collected using the ship's own Kongsberg EM 122. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data (zip file) and the cruise report for details
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
