title: Trace metal data from water samples during METEOR cruise M138

description: The file contains dissolved and total dissolvable trace metal concentrations (Fe, Co, Mn, Ni, Cd, Cu, Pb, Zn and V), hydrogen peroxide (H2O2), Fe(II), and iodide and iodate concentrations of surface water samples and station depth profiles. Trace metal concentrations were measured by ICP-MS after preconcentration (Rapp et al. 2017, Anal. Chim. Acta). Fe(II) and H2O2 were analyzed on-board using chemiluminescence flow injection analysis (Hopwood et al. 2017, Sci. Rep.). Iodide concentrations were analyzed by cathodic stripping square wave voltammetry (Luther et al. 1988, Anal. Chem.) and Iodate concentrations were measured spectrophotometrically (Chapman and Liss 1977, Mar. Chem.).

title: Supplementary material to: MIS 5e relative sea level indicators: new methodologies to sustain the quantitative estimate of past sea level changes

description: During the Marine Isotopic Stage (MIS) 5e global sea level was 6-9 m higher than today. The only direct observations of this sea level are paleo relative sea-level (RSL) indicators. Their relationship to sea level is called the indicative meaning and is quantified by the reference water level and the indicative range. In this thesis, some of the problems around the determination of the indicative meaning, precise elevation measurements and structured reporting of databases are addressed. In the first chapter, I will show how sea-level indicators can be categorized from a geomorphological perspective. In the second and third chapter, I will show the possibility of using morpho- and hydrodynamic models to derive the limits of the indicative meaning and to assess changes in paleo tidal ranges. In a final chapter, I will use these methodologies, describe how they can help deriving the paleo RSL without site-specific data and attribute the results to the global MIS 5e sea-level database.

title: Grain size section mean data for the upper 1340 m of the EGRIP ice core and eleven c-axes stereo plots (all derived with the Fabric Analyzer G50)

description: Mean ice grain size and crystal-preferred orientation data was obtained from vertical thin sections (ca. 6.7 x 9 cm²) of the East Greenland Ice Core Project (EGRIP) ice core to analyze the microstructural evolution and internal deformation with depth. Vertical ice thin sections were prepared and measured with the Fabric Analyzer G50 (resolution: 20 μm/pixel) in the field at the EGRIP site in the summer seasons between 2017 and 2019. 55 cm long sample were cut into six thin sections and used to calculate mean grain size values for these 9 cm long sections with the program cAxes for the upper 1340 m of the ice core. The stated depth of the section represents the center of the section.At depths of 138.92 m, 276.88 m, 415.3 m, 514.48 m, 613.3 m, 757.21, 899.94 m, 1062.65 m, 1141.2 m, 1256.98 m, and 1339.75 m the orientation of each crystal in the representitive thin section was measured with the Fabric Analyzer G50 to analyze the internal deformation at those depths. Crystal orientations per sample are represented in eleven c-axes stereo plots from those depths. Stereoplots are not geographically truly orientated due to loss of orientation during ice core retrieval.

title: Model results, link to archive file

description: The evolution of a hydrometeor ensemble („cloud“ ) can be described using a balance equation for its size spectrum. In numerical weather prediction or climate models, however, this approach is too time consuming. It is therefore necessary to capture, if only approximately, the on-going microphysical processes in a cloud using a parame- terised form of modelling. The parameterisation of sedimentation alone is already a demanding task. If its standard form is used in a two-moment scheme, the mean mass of the hydrometeors will be too large for a cloud physics context. Existing approaches try to avoid excessively large mean masses by altering dynamically the parameterisation assumptions in the running model.In this work, a new fundamental approach is presented: the assumption of a spectrum containing particles of all sizes is replaced by its truncation at a particle size realistic in cloud physics. The calculation of integrals over the truncated spectrum requires a new technique, which demands higher computational effort.In this work, comparisons of the new parameterisation with already existing parameterisations are made while changing the initial conditions and the advection scheme. With the new method, the parameterisation error is reduced by up to 50 %. The new paramerisation also constitutes a great improvement compared to the standard form when transferred to modelling an ensemble of solid hydrometeors. This is illustrated using a particle type commonly found in polar regions. Furthermore, for the first time a B-distribution is used as a basis for a cloud microphysics parameterisation. Its domain of definition is bounded by construction. This distribution, however, appears not suitable for use in two-moment schemes, because one free parameter has to be derived from model data.Extending the sedimentation model with drop collisions and starting with a cloud droplet spectrum, it is not possible to judge the quality of the sedimentation paramete- risations, because the coagulation rates are dominated by the choice of the sedimetation velocity for small droplets. If the initial spectrum already contains a sufficient number of raindrops, however, application of the new method again reduces the parameterisation error by up to 50 %.

title: Observation of ferromanganese deposits in the Baltic Sea

description: Baltic sediments have been studied by Behrens, Munthe, Küppers, Spethmann, Apstein, Sjöstedt, Pratje and the writer. The following types of sediments have been observed: varved and non-varved late-glacial clays, gray and black, post-glacial muds, and sands. The organic content of late-glacial clays ordinarily is less than 1.3 per cent, and of post-glacial muds more than 3 per cent. Sediments containing intermediate quantities are scarce. This can be explained as a result of the changed balance between organic and inorganic sedimentation when the glacial period ended; the abundance of fresh detritus then suddenly ceased and inorganic sedimentation became very much slower than before; consequently, the relative amount of organic detritus increased. As most of the material was not subjected to biological analysis, it has not been possible to distinguish different ages among post-glacial sediments.
description: From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

title: Annotated record of the detailed examination of a Mn deposits from the Carnegie Ridge in the Pacific Ocean

description: The Carnegie Ridge is a linear, aseismic, submarine ridge lying between the Galapagos Islands and the coast of South America. Surface ship, near bottom, and grain size studies from the saddle have been used to delineate the present geological environment and history of the ridge. Structurally the Carnegie Ridge is rather simple in profile, being bounded by east-west trending scarps which give the ridge a block-faulted appearance. Acoustic basement over the ridge appears smooth on reflection profiles and is composed of chert. The sedimentary sequence above the chert horizon contains a lower chalk unit overlain by calcareous ooze. Where erosion has exposed the chalk a karst-like micro-topography is present which is characterized by steep walled channels and cliffs and consolidated bed forms undergoing erosion and dissolution. The ridge crest has been stripped of almost its entire sediment cover. Thick sequences of sediment are found only in areas protected from north or south flowing bottom currents. Evidence of erosion is provided by extensive channeling on both the north and south flanks of the ridge. Near bottom observations in one channel on the north flank revealed a large field of sand dunes indicating northward, downslope sediment transport. These dunes are found on manganese-encrusted chalk which floors the channel.

title: Chemical composition of manganese nodules and crusts from the Pacific and Indian Ocean and Loch Fyne, Scotland

description: The first part of this thesis includes some topics of a non-geochemical nature but which are of importance in interpreting the geochemistry of nodules. The points covered include their distribution, petrography, structure, mineralogy and internal compositional variations. Part Two includes the geochemistry of both nodules and that of their surrounding sediments, This geochemical study has been divided into firstly, a general geochemical study of both nodules and sediments using a statistical approach to the interpretation of the data, secondly, the regional geochemistry of Pacific and Indian Ocean nodules and sediments, the latter entirely uninvestigated in the past, and thirdly, local variations in the composition of nodules. Throughout, emphasis has been placed on the geochemistry of nodules in terms of their environment of formation.
