The data of the article "Net climate effects of Manila clam culture ecosystems and their influencing factors"

The data mainly include environmental factors in the water column, porewater, and sediments, as well as the concentrations and fluxes of three greenhouse gases (CO2, CH4, and N2O) in the system. The experiment lasted 80 days, with sampling conducted at 10‑day intervals.Water samples were collected from the surface 20 cm layer, and sediment samples were collected from the upper 2 cm layer.Basic environmental parameters such as temperature and salinity were measured in situ at the sampling sites, while nutrients and greenhouse gas concentrations were analyzed in the laboratory following established standard methods after sample collection.
