“…Surprisingly, Horner et al (2011) reported no significant correlation between Alexandrium spp. cyst density and metal concentration in Puget Sound, USA, except for Table 3 List of identified dinoflagellate cysts in the Izmir Bay with their paleontological name and biological affinities according to references: Wall and Dale (1968), Head (1996), Rochon et al (1999), Rochon et al, (2009), Matsuoka and Fukuyo (2000), Radi et al (2013), Matsuoka et al (2009 Cu. Although among dinoflagellate groups such as autotrophic and heterotrophic, dinoflagellates have different survival mechanisms under metal stress conditions, acquired adapting mechanisms to a high level of metals (such as Pb and Cd) from phytoplankton is also conceivable to understand their distribution and abundance in marine ecosystems (Echeveste et al, 2014).…”

“…If necessary, additional slides were counted entirely. Taxonomy was based on Fensome and Williams (2004) and Matsuoka et al (2009). Dinoflagellate cyst taxa were divided into two groups, gonyaulacoid (G-cysts), and peridinioid and cysts of Polykrikos (P-cysts) ( Table 2).…”

The effect of meter-scale lateral oxygen gradients at the sediment-water interface on selected organic matter based alteration, productivity and temperature proxies

Abstract.A valid assessment of selective aerobic degradation on organic matter (OM) and its impact on OM-based proxies is vital to produce accurate environmental reconstructions. However, most studies investigating these effects suffer from inherent environmental heterogeneities. In this study, we used surface samples collected along two meterscale transects and one longer transect in the northeastern Arabian Sea to constrain initial OM heterogeneity, in order to evaluate selective aerobic degradation on temperature, productivity and alteration indices at the sediment-water interface. All of the studied alteration indices, the higher plant alkane index, alcohol preservation index, and diol oxidation index, demonstrated that they are sensitive indicators for changes in the oxygen regime. Several export production indices, a cholesterol-based stanol/stenol index and dinoflagellate lipid-and cyst-based ratios, showed significant (more than 20 %) change only over the lateral oxygen gradients. Therefore, these compounds do not exclusively reflect surface water productivity, but are significantly altered after deposition. Two of the proxies, glycerol dibiphytanyl glycerol tetraether-based TEX 86 sea surface temperature indices and indices based on phytol, phytane and pristane, did not show any trends related to oxygen. Nevertheless, unrealistic sea surface temperatures were obtained after application of the TEX 86 , TEX L 86 , and TEX H 86 proxies. The phytol-based ratios were likely affected by the sedimentary production of pristane. Our results demonstrate the selective impact of aerobic organic matter degradation on the lipid and palynomorph composition of surface sediments along a short lateral oxygen gradient and suggest that some of the investigated proxies may be useful tracers of changing redox conditions at the sediment-water interface.
