title: δ15Nsed and δ15NChl-a measured in sediment samples in the coastal upwelling system offshore Namibia during METEOR cruise M76/2 in 2008

description: The coastal upwelling system offshore Namibia is well-known for its high primary productivity in surface waters and denitrification in OMZ. Both processes gradually enrich the residual nitrate pool in 15N that is assimilated by phytoplankton to synthesize Chl-a and particulate organic nitrogen. To unveil the connection between the upwelled nitrate pool, molecule-specific nitrogen and bulk sediment nitrogen, we analyzed the δ15N of nitrate in seawater, and of Chl-a and bulk nitrogen in 27 surface sediments samples of northern BUS (17°S – 25°S). An offshore increase in both δ15Nsed and δ15NChl-a in the northern (17°-20°S,11°–14°E) sector is consistent with 15N enrichment during progressive nitrate assimilation by phytoplankton. In the southern sector (20°-23°S, 11°–14°E) where the OMZ is prominent, an offshore decrease of δ15Nsed and δ15NChl-a reflect assimilation of nitrate enriched in 15N by water column denitrification. The δ15Nsed and δ15NChl-a values also increase along the inner shelf from 17° to 23°S, interpreted to reflect a time-averaged imprint of denitrification and concomitant increase in δ15N of upwelled nitrate. Despite of the overall similarity in spatial patterns, paired δ15Nsed and δ15NChl-a unexpectedly lack a significant correlation (R2 = 0.22). The deviation between δ15Nsed and δ15NChl-a (△) suggests a varying post-depositional bias of diagenetic processes on the δ15Nsed whereas the original δ15NChl-a is retained. We conclude that intense diagenetic alteration of bulk N in temporally anoxic sediments shifts the δ15Nsed, whereas the sedimentary δ15NChl-a captures the integrated N-loss in the water column, and is an unbiased isotope proxy for denitrification in the OMZ.

title: Nutrients and nutrient isotope data in South Equatorial Atlantic Ocean water samples collected during the Meteor cruise M131 in 2016

description: R/V Meteor cruise M131 carried out a physical oceanography research program with a biogeochemical sampling component in the South Equatorial Atlantic Ocean and eastern boundary upwelling region off Angola and Namibia. The program was part of the EU collaborative project PREFACE (“Enhancing prediction of tropical Atlantic climate and its impacts”) and the sampling for and analysis of nutrient data were linked to BMBF collaborative project GENUS (“Geochemistry and Ecology of the Namibian Upwelling System”). CTD data of the expedition M131 are archived under doi:10.1594/PANGAEA.910994. The bottle files corresponding to water samples analysed for nutrient concentrations and nitrate isotopic composition were provided by Gerd Krahmann (GEOMAR). Depths and data for temperature, salinity, oxygen concentrations labeled “CTD“ in the table are values from calibrated CTD sensors at closure of the bottles, numbers for fluorescence are uncalibrated. Water samples were taken by Maria-Elena Vorrath during M131 and were analyzed after shipment in the laboratory of Kirstin Dähnke at Helmholtz-Zentrum Geesthacht. Nutrient concentrations were measured with an AutoAnalyzer 3 system (Seal Analytics) using standard colorimetric methods by Markus Ankele. Nitrate was determined after reduction to nitrite, followed by a reaction with sulfanilamide to form a red azo dye (Grasshoff and Anderson 1999). Phosphate was measured after formation of a blue antimony-phosphorous colour complex, according to Murphy and Riley (1962). Ammonium was measured fluorometrically based on Holmes et al. (1999). The relative errors of duplicate sample measurements were below 1.5% for NOx and phosphate concentrations, and below 0.3% for ammonium and silicate. The detection limit was &lt;0.5 µmol kg−1 for NOx, &gt; 0.1 µmol kg−1 for phosphate, &gt;0.013 µmol kg−1 for ammonium and &gt;0.016 µmol kg−1 for silicate. Delta15N_NO3 and Delta18O_NO3 were determined in the laboratory at Helmholtz-Zentrum Geesthacht (Kirstin Dähnke) with the denitrifier method (Sigman et al. 2001; Casciotti et al. 2002). The isotopic composition was determined with a GasBench II coupled to a Delta Plus XP mass spectrometer (ThermoFinnigan). Replicate measurements were performed, and two international standards (IAEA-N3, Delta15N = 4.7‰, Delta18O=25.6‰ and USGS 34 (Delta15N=-1.8‰, Delta18O=-27.9‰; Böhlke et al. 2003), were measured with each batch of samples. To correct for exchange with oxygen atoms from water, a bracketing correction was applied (Sigman et al. 2009). The standard deviation for standards and samples was 0.2‰ for Delta15N and 0.4‰ for Delta18O.

title: Underway fluorescence measurements along ship track on cruise TT049

description: The underway fluorescence data were logged every minute using Sharon Smiths Turner Designs fluorometer plumbed to the ships SAIL system. The data were manually calibrated to discreet surface chlorophyll measurements in segments determined by the times of fluorometer cleanings, as well as any changes in water mass that might have affected the calibration. Quality control consisted of range checks and removal of any readings which were obviously bubble-contaminated.
