The samples were then dispersed in water using sodium hexametaphosphate and ultrasonication.</p>\n\n<p>The PSDs were calculated using the Mie solution to Maxwell's equation, with 1.33 as the water refractive index and 1.55-0.1i as the sediment refractive index.</p>\n\n<p><strong>Data description</strong></p>\n\n<ul>\n\t<li><em>sample:</em> sample reference;</li>\n\t<li><em>date:</em> date of the analysis;</li>\n\t<li><em>laboratory:</em> analysis laboratory;</li>\n\t<li><em>H2O2:</em> has the sample been pre-treated with hydrogen peroxide?</li>\n\t<li><em>HCl:</em> has the sample been pre-treated with chloridic acid?</li>\n\t<li><em>HMP:</em> has the sample been dispersed with sodium hexametaphosphate?</li>\n\t<li><em>ultrasonication:</em> duration of ultrasonic dispersion (seconds);</li>\n\t<li><em>0.011</em> to <em>3000.000: </em>relative amount (percent) for the given grain size (micrometers).</li>\n</ul>", "license": "https://creativecommons.org/licenses/by/4.0/legalcode", "creator": [ { "affiliation": "Universit\u00e9 Bordeaux Montaigne", "@id": "https://orcid.org/0000-0001-5759-4944", "@type": "Person", "name": "Frerebeau, Nicolas" } ], "url": "https://zenodo.org/record/1969787", "datePublished": "2015-04-25", "keywords": [ "particle-size distribution", "archaeology", "ceramic", "Iron Age", "Iberian Peninsula" ], "contributor": [ { "affiliation": "CNRS", "@id": "https://orcid.org/0000-0002-9763-7600", "@type": "Person", "name": "Queffelec, Alain" } ], "@context": "https://schema.org/", "distribution": [ { "contentUrl": "https://zenodo.org/api/files/377789f4-34db-4201-8677-c57a8952ded2/GRAIN_Mas-de-Moreno_unfired.csv", "encodingFormat": "csv", "@type": "DataDownload" } ], "identifier": "https://doi.org/10.5281/zenodo.1969787", "@id": "https://doi.org/10.5281/zenodo.1969787", "@type": "Dataset", "name": "Particle-size distribution of Iberian unfired potsherds from the Late Iron Age" }
