title: Seawater carbonate chemistry and Emiliania huxleyi biological processes during experiments, 2010

description: The calcifying phytoplankton species, coccolithophores, have their calcified coccoliths around the cells, however, their physiological roles are still unknown. Here, we hypothesized that the coccoliths may play a certain role in reducing solar UV radiation (UVR, 280-400 nm) and protect the cells from being harmed. Cells of Emiliania huxleyi with different thicknesses of the coccoliths were obtained by culturing them at different levels of dissolved inorganic carbon and their photophysiological responses to UVR were investigated. Although increased dissolved inorganic carbon decreased the specific growth rate, the increased coccolith thickness significantly ameliorated the photoinhibition of PSII photochemical efficiency caused by UVR. Increase by 91% in the coccolith thickness led to 35% increase of the PSII yield and 22% decrease of the photoinhibition of the effective quantum yield by UVR. The coccolith cover reduced more UVA (320-400 nm) than UVB (280-315 nm), leading to less inhibition per energy at the UV-A band.

title: Plastic debris dataset on the Seine riverbanks: up to 38 000 (1 kg) pre-production plastic pellets reported per square meter

description: Surface debris were collected with a metal trowel over a square of 1 m² within a historical accumulation zone of plastic debris. They were collected in one shot close to the Seine river mouth (North France; 49.46452, 0.43911), the 28th of february 2020. Plastic debris higher than 6 mm were sorted and classified using the updated international MSFD and OSPAR classifications, joined as the J-list. They were then counted, weighed and data were reported in a csv file. Those data help identifying historical plastic pollution and its sources for future mitigation policies.

title: Dissolved concentrations of major elements and water isotopes for water samples from the Rio Bermejo mainstem, tributaries, spring-fed channels, and groundwater wells

description: Water samples were filtered to 0.2 micron prior to measurement. Samples for cation analysis were acidified in the field to pH &lt; 2 using 6N HNO3. Cation concentrations were measured with a Varian 720 inductively coupled plasma optical emission spectrometer (ICP-OES) at the GFZ Helmholtz Laboratory for the Geochemistry of the Earth Surface (HELGES), using SLRS-5 (Saint-Laurent River Surface, National Research Council - Conseil National de Recherches Canada) and USGS M212 and USGS T187 as external standards. We corrected for instrument drift by measuring an internal standard (GFZ-RW1) every 10 samples and we determined measurement uncertainty using calibration curve uncertainty. Anion concentrations were measured with a Dionex ICS1100 Ion Chromatograph, using USGS standards M206 and M212 as external standards for quality control, with uncertainty determined from triplicate analysis. We corrected cation concentrations for cyclic salt inputs following Bickle et al. (2005, doi:10.1016/j.gca.2004.11.019).

title: Zoobenthos and sediments time series at List Reede, Sylt, Germany: pilot samples in 2001

description: In preparation for a forthcoming monitoring project, a shallow subtidal area in the northern Wadden Sea was studied for macrozoobenthos &gt;1 mm sieve size. Using a Reineck-type box-corer of 0.02 m² surface area, abundance and specific composition were evaluated from a sampling grid of 21 positions with two replicates each. Temporarily, sampling was repeated 9 times. Analyses of spatial and temporal variability revealed that within-site variability was far lower than between-site variability. As a consequence, the later monitoring project was based on a higher number of study sites at the cost of within-site replication.

title: Biogeochemical data during RV POLARSTERN cruise PS109

description: The concentration and carbon isotope delta (δ13C) of methane (CH4), the water mass tracer δ18O(H2O), and nutrient concentrations were measured in seawater during the Polarstern expedition PS109. The expedition took place from 12 September to 14 October 2017, on the Northeast Greenland continental shelf. Seawater samples were collected using a shipboard Sea-Bird Scientific SBE911plus CTD (Conductivity-Temperature-Depth) profiler, integrated into a SBE32 Carousel Water Sampler with 24 Niskin bottles of 12 L each (Kanzow et al., 2018). The analysis of CH4 concentrations and carbon isotope delta, 13C, were done using a gas chromatograph (Agilent GC 7890B) with a Flame Ionization Detector (FID) and a Thermo Finnigan Delta plus XP mass spectrometer, respectively (Verdugo et al., 2022). The δ18O(H2O) samples were analyzed using a Finnigan MAT Delta S mass spectrometer with two equilibration units. Unfiltered nutrient samples were taken in 15 mL Falcon tubes at the same depth as CH4 concentrations and (δ13C) of CH4 samples, stored at -20°C, and were analyzed for nitrate+nitrite, phosphate, nitrite, and silicate on a four-channel SEAL Analytical nutrient AutoAnalyser 3.

title: δ¹⁸Osw benthic-corrected on planktonic foraminifera of sediment core MD01-2378

description: AGE follows the GICC05 time scale. To estimate changes of d18Osw of the sea surface and upper thermocline water, we used paired G. ruber and P. obliquiloculata Mg/Ca temperatures and stable isotopes and calculated the d18Osw using the equation of Bemis et al. (1998, doi:10.1029/98PA00070). The ice volume effect was corrected using the benthic d18Osw from the same core.

title: Planktonic and benthic foraminiferal stable isotopes, SSTs and thermocline temperature, coccoliths and benthic foraminiferal assemblages, and productivity reconstruction for sediment core MD06-3067

description: We present sea surface, upper thermocline, and benthic d18O data, as well as temperature and paleoproductivity proxy data, from the International Marine Global Change Study Program (IMAGES) Core MD06-3067 (6°31'N, 126°30'E, 1575 m water depth), located in the western equatorial Pacific Ocean within the flow path of the Mindanao Current. Our records reveal considerable glacial-interglacial and suborbital variability in the Mindanao Dome upwelling over the last 160 kyr. Dome activity generally intensified during glacial intervals resulting in cooler thermocline waters, whereas it substantially declined during interglacials, in particular in the early Holocene and early marine oxygen isotope stage (MIS) 5e, when upwelling waters did not reach the thermocline. During MIS 3 and MIS 2, enhanced surface productivity together with remarkably low SST and low upper ocean thermal contrast provide evidence for episodic glacial upwelling to the surface, whereas transient surface warming marks periodic collapses of the Mindanao Dome upwelling during Heinrich events. We attribute the high variability during MIS 3 and MIS 2 to changes in the El Niño Southern Oscillation state that affected boreal winter monsoonal winds and upper ocean circulation. Glacial upwelling intensified when a strong cyclonic gyre became established, whereas El Niño–like conditions during Heinrich events tended to suppress the cyclonic circulation, reducing Ekman transport. Thus, our findings demonstrate that variations in the Mindanao Dome upwelling are closely linked to the position and intensity of the tropical convection and also reflect far-field influences from the high latitudes.

title: (Table S1) Stable oxygen isotopic values and Mg/Ca ratios of Globigerinoides ruber w from sediment core AAS9_21

description: Variations in sea surface temperature (SST), d18O of sea water (δ18Ow), and salinity were reconstructed for the past 68 ka using a sediment core (AAS9/21) from the eastern Arabian Sea (EAS) in order to understand the changes in evaporation and precipitation associated with the monsoon system. The Mg/Ca-derived SST record varies by ~4°C; it shows that marine isotope stage (MIS) 4 was warmer than MIS 3, that the Last Glacial Maximum was 4°C cooler than the present, and that there was a 2°C increase within the Holocene. MIS 4 records higher d18Ow and salinity values than MIS 2, suggesting variable flow of low-salinity Bay of Bengal flow into the EAS during glacial periods. The transition from MIS 4 to MIS 3 was marked with a conspicuous shift from higher to lower d18Ow values, which reflects a decrease in the evaporation-precipitation budget in the EAS, perhaps due to the strengthening of southwest monsoon. Monsoon reconstructions based on d18Ow reveal that monsoon-driven precipitation was higher during MIS 3 and MIS 1 and was lower during MIS 2 and MIS 4. This is consistent with earlier monsoon reconstructions based on upwelling indices from the western Arabian Sea. However, the amplitude of monsoon fluctuations derived through upwelling indices and d18Ow varies significantly, which may indicate spatial variability of monsoon rainfall.

title: Benthic stable oxygen and carbon isotope records; XRF scanner S and EDP XRF S, and foraminiferal assemblages of sediment core M125-95-3

description: Negative excursions in the stable carbon isotopic composition (δ¹³C) at Atlantic intermediate to mid-depths are common features of millennial-scale events named Heinrich Stadials (HS). The mechanisms behind these excursions are not yet fully understood, but most hypotheses agree on the central role played by the weakening of the Atlantic meridional overturning circulation. Marine records registering millennial-scale negative δ¹³C excursions in the Atlantic are mostly restricted to the HS of the last deglacial, while the HS of the last glacial are poorly studied. Here we constrain changes in bottom water ventilation in the western tropical South Atlantic mid-depth during HS of the last glacial and deglacial by investigating marine core M125-95-3. The concurrent decreases in benthic foraminifera δ¹³C and increases in bulk sediment sulfur indicates an increased Northern Component Water (NCW) residence time in the western tropical South Atlantic mid-depth during HS. Furthermore, a coherent meridional pattern emerges from the comparison of our new data to previously published mid-depth records from the western South Atlantic. While our record shows the largest negative δ¹³C excursions during almost all HS, the western equatorial Atlantic showed medium and the subtropical South Atlantic showed the smallest negative excursions. This meridional pattern supports the notion that during HS a reduction in the NCW δ¹³C source signal together with the accumulation of respired carbon at NCW depths drove the negative δ¹³C excursions. We suggest that the negative δ¹³C excursions progressively increase along the NCW southwards pathway until the signal dissipates/dilutes by mixing with Southern Component Water.
