title: (Table S1) Concentration of GLY and MGLY on marine aerosol particles, 24 hours sampling time from midnight to midnight (UTC) during POLARSTERN cruise ANT-XXVII/4

description: Aerosol particles were sampled using a high volume sampler equipped with quartz fiber filters. The aerosol sampler was installed on top of the observation deck (height ca. 30 m). The aerosol particle data represent clean marine conditions (air masses from the open sea, concentration of elemental carbon &lt; 60 ng/m**3). From the aerosol particles inorganic ions and organic matter was measured. Particulate oxalic acid was determined with ion chromatography. The alpha dicarbonyls glyoxal (GLY) and methylglyoxal (MGLY) from marine aerosol particles were determined with an analytical method based on derivatisation with o-(2,3,4,5,6-Pentafluorobenzyl)-hydroxylamine (PFBHA) reagent, solvent extraction and GC-MS (SIM) analysis.

title: (Table 1) Sr, Nd and Os isotopic composition from marine sediments of the Bengal Fan

description: Sr, Nd, and Os isotopic data are presented for sediments from diverse locations in the Bay of Bengal. These data allow the samples to be divided into three groups, related to their sedimentary contexts. The first group, mainly composed of sediments from the shelf off Bangladesh and the currently active fan, has Sr and Nd characteristics consistent with a dominantly Himalayan source. Their 187Os/188Os ratios (~1.2-1.5) show that the average detrital material delivered by the Ganga-Brahmaputra (G-B) river system is not unusually radiogenic. A large difference in 187Os/188Os ratio exists between these Bengal Fan sediments and Ganga bedloads (187Os/188Os ~2.5, Pierson-Wickmann et al. (2000, doi:10.1016/S0012-821X(00)00003-0)). This difference mainly reflects addition of a less radiogenic Brahmaputra component, though mineralogical sorting and loss of radiogenic Os during transport may also play some role. The second sample group contains sediments from elsewhere in the Bay, particularly those located on the continental slope. They display Os isotopic compositions (0.99-1.11) similar to that of present seawater and higher Os and Re concentrations. These characteristics suggest the presence of a large hydrogenous contribution, consistent with the lower sedimentation rate of these samples. Sr and Nd ratios indicate that a significant fraction of these sediments is derived from erosion of non-Himalayan sources, such as the Indo-Burman range. These observations could be explained by the deflection of sediments from the G-B river system by westward currents in the head of the Bay. The third group contains only one sample, but shows that in addition to a Himalayan source, sediment discharge from Sri Lanka may influence the detrital component in the distal part of the fan. The similarity between the isotopic compositions of the group I R/V Sonne samples and those of Ocean Drilling Program Leg 116 (France-Lanord et al., 1993; Reisberg et al., 1997, doi:10.1016/S0012-821X(00)00003-0) suggests that the material eroding in the Himalayas has been roughly constant since the Miocene. The high Os isotopic ratios of leachates of both Sonne group I and Miocene Leg 116 sediments imply that much of the leachable highly radiogenic Os component was conserved during transport through the estuary or interaction with seawater. In constrast, samples with lower, but still relatively high, sedimentation rates (Sonne groups II and III and Pliocene Leg 116) seem to have significantly adsorbed or exchanged Os and Re with seawater. This suggests that in some cases the Os isotopic ratios of leachates of detrital sediments can be used to constrain the ancient marine Os record, or conversely, to date unfossiliferous sediments.

title: Chlorophyll a measured on water bottle samples during POLARSTERN cruise ARK-XXII/2

description: In order to convert the flow through fluorescence to Chl a concentration, discrete seawater samples were collected from Niskin bottles and about 0.5-2.0 L of seawater was filtered through Whatman GF/F filters and stored at -18°C. At the Alfred Wegener Institute for Polar and Marine Research, the filters were extracted in 90% acetone and analyzed with a spectrophotometer for higher values and with a Turner Design fluorometer for lower values.

title: Particulate organic carbon measured on water bottle samples during POLARSTERN cruise ARK-XXII/2

description: Method: Filtration of 1 L (surface) to 4 L (deep water) onto GF/F filters pre-combusted at 500°C for 4 h. Filters were soaked in 0.1 N HCl for removal of inorganic carbon and dried at 60°C. POC measurements were then conducted on a Carlo Erba CHN elemental analyzer.

title: (Table 2) Zinc complexation data from POLARSTERN cruise ANT-XXIV/3

description: The speciation of dissolved zinc (Zn) was investigated by voltammetry in the Atlantic sector of the Southern Ocean along two transects across the major frontal systems: along the Zero Meridian and across the Drake Passage. In the Southern Ocean south of the APF we found detectable labile inorganic Zn throughout the surface waters in contrast to studies from lower latitudes. Using a combination of ASV titrations and pseudopolarography revealed the presence of significant concentration of electrochemically inert Zn ligands throughout the Southern Ocean. These ligands however were nearly always saturated due to the presence of excess concentrations of dissolved Zn that were associated with the high nutrient waters south of the Antarctic Polar Front (APF). Only in surface waters did the concentration of Zn complexing ligands exceed the dissolved Zn concentrations suggesting a biological source for these ligands. Our findings have clear implications for the biogeochemical cycling of Zn and for the interpretation of paleo records utilizing Zn in opal as a tracer of Zn speciation in the water column.
description: Titrations were performed on a much larger data set. The data below are from the small subset of data where significant excess ligand was present.
