Organic-walled dinoflagellate cyst counts in surface sediments of the Ría de Vigo (Atlantic margin of NW Iberia)


This dataset includes counts of organic-walled dinoflagellate cysts identified in 31 surface sediment samples (from van even drags and corer top samples) collected along the Ría de Vigo axis (NW Iberia). Samples were taken at different water depths (from the intertidal to a max. of 41 m depth, in different campaigns carried out between 2006 and 2014. Sediment samples were processed at the Palynology and Palaeobotany Laboratory, at the University of Vigo (Spain), using the standard palynological extraction procedures that included oven drying, treatment with HCl and HF at room temperature, the addition of exotic markers (Lycopodium spores) for concentration estimates (Mertens et al., 2009) and sieving to remove coarse (> 120 mm) and fine (< 10 mm) materials. Cysts were counted under a light microscope (Nikon Eclipse 50i and Olympus BX50) using 400× and 600× magnifications (1000× for critical determinations). The interpretation of cyst distribution in relation to environmental gradients can be found in García-Moreiras et al. (2023).
