title: Micro-fibre content of South Africa's sandy beach sediments from 2016 to 2017

description: In 2016 and 2017 the Department of Environmental Affairs conducted sampling at more than 150 sandy beach sites along the South African coastline, to quantify the extent of micro-plastic pollution at an average spatial sampling scale of about 15 km. Most of the sites along the west coast were sampled 3 times, to investigate seasonal variability. The east and south coasts were sampled twice, during low and higher river runoff conditions, respectively. At all sites, plastic micro-fibres were found to be the dominant micro-plastic constituents present, and the quantitative data for that is presented in this dataset. One of the problematic issues related to comparison of global micro-plastic pollutant levels, presently, is the lack of agreed to measurement methodologies and reporting units. This dataset represents results for samples taken along the high-level water mark, as a composite sample of about 1 L consisting of aliquots taken from at least 3 different sampling spots, sampled to a depth of 5 cm. The micro-fibre count is reported as the number of fibres per liter (or #F/dm3). In order to convert this to other units for comparison with other studies, sediment dry bulk density measurements are included. Data is also provided for the dominant sediment grain size (fine sand is 63 to 250 µm, and medium-coarse sand 250 µm to 1 mm) , and the temperature and salinity of surf-zone water at the time of sampling.

title: (Table S1) TEX86 and BIT record from sediment core PBBC-1

description: A molecular organic geochemical proxy (TEX86) for sea surface temperature (SST) is compared with a foraminifera-based SST proxy (Mg/Ca) in a decadal-resolution marine sedimentary record spanning the last 1000 years from the Gulf of Mexico. We assess the relative strengths of the organic and inorganic paleoceanographic techniques for reconstructing high-resolution SST variability during recent climate events, including the Little Ice Age (LIA) and the Medieval Warm Period (MWP). SST estimates based on the molecular organic proxy TEX86 show a similar magnitude and pattern of SST variability to foraminiferal Mg/Ca-SST estimates but with some important differences. For instance, both proxies show a cooling (1°C-2°C) of Gulf of Mexico SSTs during the LIA. During the MWP, however, Mg/Ca-SSTs are similar to near-modern SSTs, while TEX86 indicates SSTs that were cooler than modern. Using the respective SST calibrations for each proxy results in TEX86-SST estimates that are 2°C-4°C warmer than Mg/Ca-SST throughout the 1000 year record. We interpret the TEX86-SST as a summer-weighted SST signal from the upper mixed layer, whereas the Mg/Ca-SST better reflects the mean annual SST. Downcore differences in the SST estimates between the two proxies (DeltaT = TEX86 - Mg/Ca) are interpreted in the context of varying seasonality and/or changing water column temperature gradients.
description: Each raw TEX86 and BIT index value represents the mean of 3-6 measurements per sample.

title: Coastal water quality monitoring along the South African coastline in 2016 and 2017, with in situ T-S-O2-pH and laboratory chlorophyll-a, phosphate and nitrate measurements

description: The first comprehensive survey of basic physico-chemical water quality parameters along the South African coastline was carried out from 2016 to 2017, at more than 200 sampling sites. The west coast (Port Nolloth to Cape Town) was sampled 3 times, to establish seasonal variability associated with upwelling. The south- and east coasts (Cape Town to Sodwana) was sampled twice, to capture the influence of river runoff during high versus low river runoff conditions. The data can be used to assist with the revision of existing Water Quality Guidelines, which at present is inadequate due to a lack of comprehensive baseline data for these water quality parameters. The data also suggest areas of concern and that may be prone to land-based sources of pollution and eutrophication, and acidification, that will be discussed in more detail in manuscripts to be finalised.

title: Microbial communities at Sundarban Mangrove forest water samples

description: Microbial community of world largest Sundarban mangrove areas strongly effected by contaminated surface waters of its upstream regions. This investigation identifies microbial communities of marine water samples from India mangrove forest through 16S rRNA gene-based amplicon sequencing approach targeting V3-V5 hypervariable regions. Total eighteen samples from two spatially separated sampling stations with varied physiochemical properties selected in this study. Total nine marine water samples from one pristine island of mangrove forest with lower nutrient load showed unique microbial assembles. In comparison to that, we observed a shift of bacterial community in open marine water columns (three nine samples represents Station 2 with an elevated nutrient load. Not much change in Archaeal communities was observed.

title: Regional vegetation changes in the tropical Andes expressed as arboreal pollen (AP%), standardised ordination scores (DCA z-scores), and aquatic vegetation ratios (D/SS); files used for plots

description: We compare eight pollen records reflecting climatic and environmental change from the tropical Andes. Our analysis focuses on the last 50 ka, with particular emphasis on the Pleistocene to Holocene transition. We explore ecological grouping and downcore ordination results as two approaches for extracting environmental variability from pollen records. We also use the records of aquatic and shoreline vegetation as markers for lake level fluctuations, and precipitation change. Our analysis focuses on the signature of millennial-scale variability in the tropical Andes, in particular, Heinrich stadials and Greenland interstadials. We identify rapid responses of the tropical vegetation to this climate variability, and relate differences between sites to moisture sources and site sensitivity.

title: Sea surface temperature (TEX86), marine GDGTs and BIT index from ODP Hole 161-977A

description: The TEX86H temperature proxy is a relatively new proxy based on crenarchaeotal lipids and has rarely been applied together with other temperature proxies. In this study, we applied the TEX86H on a sediment core from the Alboran Sea (western Mediterranean, core ODP-977A) covering the penultimate climate cycle, that is, from 244 to 130 ka, and compared this with previously published sea surface temperatures derived from the Uk'37 of alkenones of haptophyta and Mg/Ca records of planktonic foraminifera. The TEX86H temperature record shows remarkably similar stadial-interstadial patterns and abrupt temperature changes to those observed with the Uk'37 palaeothermometer. Absolute TEX86H temperature estimates are generally higher than those of Uk'37, though this difference (&lt;3°C in 81% of the data points) is mainly within the temperature calibration error for both proxies, suggesting that crenarchaeota and haptophyta experienced similar temperature variations. During occasional events (&lt;5% of the analyzed time span), however, the TEX86H exhibits considerably higher absolute temperature estimates than the Uk'37. Comparison with Mg/Ca records of planktonic foraminifera as well as other Mediterranean TEX86 and Uk'37 records suggests that part of this divergence may be attributed to seasonal differences, that is, with TEX86H reflecting mainly the warm summer season while Uk'37 would show annual mean. Biases in the global calibration of both proxies or specific biases in the Mediterranean are an alternative, though less likely, explanation. Despite differences between absolute TEX86H and Uk'37 temperatures, the correlation between the two proxies (r**2 = 0.59, 95% significance) provides support for the occurrence of abrupt temperature variations in the western Mediterranean during the penultimate interglacial-to-glacial cycle.

title: Temporal evolution of alkenones and derived SST of sediment core SVAIS-04, Norwegian Sea

description: A marine sediment core retrieved from the middle continental slope of the northwestern Barents Sea was analyzed for its geochemical (alkenones) and micropalaeontological (diatoms, coccolithophores and dinocyst) content in order to reconstruct the evolution of upper ocean conditions and ice-sheet dynamics during the last 25 kyr. Additionally, quantitative reconstructions of sea surface conditions (temperature, salinity and sea-ice cover extent) were conducted based on the best analogue technique applied to dinocyst assemblages and on the alkenone unsaturation index. The sediment core contains a post Last Glacial Maximum depositional sequence unaffected by stratigraphic discontinuities. Low salinity and laminated sediments after 20 cal kyr BP, indicate a massive settling of meltwater sediment-laden plumes from the initial melting of the Svalbard-Barents Sea Ice Sheet on Western Svalbard. First record of measurable alkenones, together with a drop of the number of months of sea-ice cover and increase in SSTs suggests an intensification of the influx of Atlantic waters into the study area at ~ 15 cal kyr BP representing the termination of the last glacial period and onset of the Bølling interstadial. The first occurrence of diatoms and increase in the abundance of all microfossils marked the onset of the Holocene at 11.2 cal kyr BP when modern-type sea surface conditions were rapidly established in Western Svalbard. Reconstructions based on dinocyst data and alkenone unsaturation index suggest relatively warm and stable temperatures between 9.9 and 8.9 kyr BP and a decrease of SSTs from 4.2 cal kyr BP to present coinciding with the Holocene Thermal Maximum and the decrease of summer insolation in the high latitude northern hemisphere, respectively.

description: Inferred from the integration of the data of Okada and Thierstein (1979, doi:10.2973/dsdp.proc.43.117.1979) with this study. In this study, the zonal boundaries are located at the LO or HO of the zonal markers, independent of their frequency. Although in the text Okada and Thierstein (1979) indicated that they relied on the HOs and LOs of markers to delineate zonal boundaries, location of these latter in their range chart (their table 3B) does not follow from this. This table gives the actual LOs and HOs of marker species given by Okada and Thierstein. Significant discrepancies in their data occur for the NP4/NP5 zonal boundary, located between samples 43-384-10-3,49-50 and 43-384-10-2,119-120, whereas the LO of F. tympaniformis is shown between 43-384-10-5,54-55 and 43-384-10-4,55-56. The former position is consistent with the data presented here. Lesser discrepancies include the delineation of the NP6/NP7 zonal boundary between 43-384-8-3, 124-125 and 43-384-8-4,49-50 with respect to the LO of D. mohleri, and that of the Discoaster nobilis Zone (Zone CP7 of Okada and Bukry, 1980 = upper Zone NP8) between 43-384-7-5,59-60 and 43-384-7-6,49-50 compared to the LO of D. nobilis between 43-384-7-6,109-110 and 43-384-7-CC
