Marine metagenomes and metatranscriptomes from 3 sediment samples along a pH gradient in Papua New Guinea. Sediment Metagenomes Papua New Guinea

Sediment microbial communities are key players in biogeochemical cycling and the remineralization of organic matter on tropical reefs. To better understand the long-term effects of low pH conditions on sediment microbial communities, microbial diversity and community composition were investigated at naturally CO2-rich tropical coral reefs in Papua New Guinea. Metagenomic and metatranscriptomic analyses will reveal insights into the response of sediment microbial communities and their functions to low pH environments.
