title: Metagenomic sequencing library of coastal marine sediments from Mai Po Nature Reserve: depth 13-16cm
design: The MP5 samples were obtained from Mai Po Nature Reserve (Hong Kong) on 12 September 2014. This subsurface sediment samples were collected from an intertidal mudflat with the depth of 1316 cm. After collection, bulk sediments were immediately sealed in plastic bags, placed in a precooled icebox and transported to the laboratory within 4 h. For each sample, DNA was extracted from 5 g sediment using PowerSoil DNA Isolation kit (Qiagen), according to the manufacturers protocol.
