This dataset contains 1) inorganic geochemical data obtained using an Itrax XRF core scanner, 2) inorganic geochemical concentrations measured by ICP-AES on a series of 102 subsamples, and 3) grain-size data for 92 size classes measured by laser diffraction particle size analysis. Sediment core PC29A was obtained from Quitralco Fjord during cruise CIMAR (Cruceros de Investigacion Marina) Fiordos 7 in February 2001.
Coverage Scope: Regional (Continents, Oceans)
Geographic Location: Chilean Patagonia, Quitralco Fjord
