title: Volume susceptibility of sediment core SO202/1_41-1

description: Magnetic volume susceptibility k is the ratio of sample magnetization change per applied external magnetic field change. It is unitless in the SI unit system, which we signalize by the letters 'SI' after the ratio value. Magnetic volume susceptibility k was measured on all full cores at increments of 2 cm using a shipboard GEOTEK Multi Sensor Core Logger (MSCL) equipped with a Bartington M.S.2 susceptibility meter and a 140 mm loop sensor. Sharp lithology changes (e.g. ash layers, dropstones) are smoothed in these susceptibility data due to the coil-size related averaging over a core interval of about 8 cm (halfwidth of sensor characteristic).

title: (Table S3) Dissolved REE concentrations, PAAS-normalized Eu anomalies (Eu/Eu*)N, Yb/Er ratios (Yb/Er)N and HREE/LREE ratios (HREE/LREE)N for seawater samples

description: Recent studies suggest that transport and water mass mixing may play a dominant role in controlling the distribution of dissolved rare earth element concentrations ([REE]) at least in parts of the North and South Atlantic and the Pacific Southern Ocean. Here we report vertically and spatially high-resolution profiles of dissolved REE concentrations ([REE]) along a NW-SE transect in the West Pacific and examine the processes affecting the [REE] distributions in this area. Surface water REE patterns reveal sources of trace element (TE) input near South Korea and in the tropical equatorial West Pacific. Positive europium anomalies and middle REE enrichments in surface and subsurface waters are indicative of TE input from volcanic islands and fingerprint in detail small-scale equatorial zonal eastward transport of TEs to the iron-limited tropical East Pacific. The low [REE] of North and South Pacific Tropical Waters and Antarctic Intermediate Water are a long-range (i.e., preformed) laterally advected signal, whereas increasing [REE] with depth within North Pacific Intermediate Water result from release from particles. Optimum multiparameter analysis of deep to bottom waters indicates a dominant control of lateral transport and mixing on [REE] at the depth of Lower Circumpolar Deep Water (?3000 m water depth; ~75-100% explained by water mass mixing), allowing the northward tracing of LCDW to ~28°N in the Northwest Pacific. In contrast, scavenging in the hydrothermal plumes of the Lau Basin and Tonga-Fiji area at 1500-2000 m water depth leads to [REE] deficits (~40-60% removal) and marked REE fractionation in the tropical West Pacific. Overall, our data provide evidence for active trace element input both near South Korea and Papua New Guinea, and for a strong lateral transport component in the distribution of dissolved REEs in large parts of the West Pacific.

title: Air-sea gas transfer velocities in the Baltic Sea measured with the Active Controlled Flux Technique

description: Heat transfer velocities measured during three different campaigns in the Baltic Sea using the Active Controlled Flux Technique (ACFT) with wind speeds ranging from 5.3 to 14.8 m s−1 are presented. Careful scaling of the heat transfer velocities to gas transfer velocities using Schmidt number exponents measured in a laboratory study allows to compare the measured transfer velocities to existing gas transfer velocity parameterizations, which use wind speed as the controlling parameter. The measured data and other field data clearly show that some gas transfer velocities are much lower than the empirical wind speed parametrizations. This indicates that the dependencies of the transfer velocity on the fetch, i.e., the history of the wind and the age of the wind wave field, and the effects of surface active material need to be taken into account. Data set contains: Measured heat transfer velocities kheat in dependency of time, position, wind speed and water and air temperature for the measurements on RV Alkor and RV Aranda in 2009 and 2010. Furthermore the Prandtl number Pr, the Schmidt number exponent n and the scaled transfer velocity k600 are given. The given times are approximate starting times in UTC. Each measurements lasted about 20 min.

title: Sediment echo sounding during Maria S. Merian cruise MSM47

description: .SGY files were recorded with the onboard parasound system. The Atlas PARASOUND system P70 uses the parametric effect, which occurs when very high (finite) amplitude sound waves are generated. If two waves of similar frequencies are generated simultaneously, also the sum and the difference of the two primary frequencies are emitted. For the PARASOUND System, 18 kHz is one fixed primary frequency, which is generated by a transducer of ~ 1m length within a beam of 4.5°. The second primary frequency can be varied between 18.5 and 24 kHz, resulting in difference frequencies from 0.5 to 6.0 kHz. The system treats three signals separately: the primary high frequency signal (18 kHz; PHF), the secondary low frequency signal (selectable 0.5 to 6.0 kHz; SLF) and the secondary high frequency (selectable 36.5 to 42 kHz; SHF). We selected 4 kHz as SLF and 40 kHz as SHF. The segy files attached here represent the SLF signal.

title: Swath sonar bathymetry during maria S. Merian cruise MSM47 with links to multibeam raw data files

description: .ALL files correspond to the mutlibeam echo sounder data collected with Merian's EM122 system. The nominal sonar frequency is 12 kHz with an angular coverage sector of up to 150° and 864 soundings per ping. The EM122 has a dual swath capacity, hence one ping consist of two swathes of up to 432 soundings each. The dual swath capacity increases the along track resolution of the multibeam data. The typical depths in our investigation area are between 500 and 5000 m water depth, allowing spacing bathymetry grid resolution of about 30 m to 200 m across and along, given survey velocities between 4.5 and 12 kn. The achievable swath width on a flat bottom will normally be up to six times the water depth. However, we limited the swath width to 15 km and 65° in order to guarantee good resolution in across track direction in deep water. Preliminary grids of the data (.grd) created during the research survey are made available for the bathymetry (MSM47finalgrid.grd, WGS84, Geographic) and backscatter data (MSM47finalgrdsss.grd, WGS84 Geographic).

title: Free fall cone penetration tests (CPT) data recorded during Maria S. Merian cruise MSM47

description: CPT_"station name".zip are compressed folders which includes the free fall cone penetration tests (CPT) data recorded during the cruise. CPT probes were used to conduct measurements of the geotechnical properties of initial and post-failure sediments along the St. Pierre Slope (refer to cruise report). CPT is an effective method for measuring in-situ physical parameters of the uppermost sediments by means of cone resistance and pore pressure. These parameters can then be used to calculate geotechnical parameters such as undrained shear strength and sensitivity, which are essential for estimating slope stability. Further information on the stations done during MSM47 are described in the cruise report.
