This is the collection of metagenome-assembled genomes that were reconstructed from metagnomes from hydrothermal plume metagenomes (Guaymas Basin, Cayman Rise and Lau Basin) and Cayman_vent_fluid metagenomes. This project is aiming to find potentially novel microbial groups that are inhabiting hydrothermal environments and of ecological importance. Remarks: MAG names here start with "SZUA" (SZU: Shenzhen U), while in some papers, they are labeled as "HVA" (HV: Hydrothermal Vent). These are just labeling differences.
