title: Metagenomic sequencing of metagenome: Pulau Ubin mangrove sediment CJ site 10cm
design: A 100-meter transect was established parallel to the shoreline. After removing the top 12 cm of surface sediment to avoid contamination, sediment samples were collected at six depth intervals: 010 cm, 1020 cm, 2030 cm, 4050 cm, 6070 cm, and 8090 cm.
