Bulk grain size of sediment core MVSEIS08_TG-2 from Gulf of Cadiz@en

Organic matter was eliminated with 33% of hydrogen peroxide (H2O2) and carbonates removed with 0.2N hydrogen chloride (HCl). Then, samples were dispersed with 0.5% Na-hexametaphosphate (Calgon) and ultra-sonicated for 2 min. Prior to grain-size analysis in a Sedigraph Micromeritics III Plus, samples were homogenised by stirring in a magnetic plate for 30 min.采用33%过氧化氢（H₂O₂）去除样品中的有机质，以0.2当量浓度的氯化氢（HCl）脱除其中的碳酸盐。随后，使用0.5%六偏磷酸钠（Calgon）对样品进行分散，并超声处理2分钟。在使用麦克默瑞提克Sedigraph III Plus粒度分析仪进行粒度分析之前，将样品置于磁力搅拌器上搅拌30分钟以实现均质化。
