Description

A sampling of 179 stations (regular grid, distance of 500 m between stations) was conducted in January and February 2016 (on 19, 20, 21 January 2016, with tidal coefficients of 56 to 72; and on 13 February 2016, with a tidal coefficient of 94) using a 0.04 m2 Shipeck grab aboard the GPMH (Grand Port Maritime du Havre) vessel “Le Marais”, between the Cap de la Hève and the Cap d’Antifer (Bay of Seine). Colum A to C: Coordinates in decimal degrees for all stations studied between Cape Hève and Cape Antifer. Column D to I, XRF measurement results (Xsort, ppm) for Si (silicon), S (sulphide), As (arsenic), BrOrg (organic bromine), Rb (rubidium), Pb (lead). Column J: TOC content obtained by combustion in a LECO CS 744 carbon sulphur analyzer (%). Column K and L: mediane and mean of Particule size, analyzed with laser diffraction particle-size analysez. Column M: group defined for interpretation into publication.
