title: 2000-2019 subsurface biomass treatment dataset under the Chesapeake Bay Wetlands OTC experiment, USA
title: 美国切萨皮克湾湿地OTC试验下2000-2019年地下生物量处理数据集

description: The raw data is an in situ OTC experiment conducted by the Smithsonian in the Chesapeake Bay wetlands, USA, and this part of the data was processed. The data contain mainly.Precipitation, sea level, and temperature data for the growing season (May-July) from 2000-2019, and total precipitation, mean sea level, and mean temperature data were calculated using R language. The table has 18 columns of data, with precipitation in cm, sea level in cm, and temperature in °C.Porewater salinity data for the growing season (May-July) 2002-2013 under control and elevated CO2 treatments were calculated using the R language for mean salinity, and missing data were missing from the original data. The table has 19 columns of data, salinity in psu. Community is the sampling community, Chamber is the OTC facility number, Treatment is the treatment, Depth is the sampling depth, Ambient (A) is the control treatment, and Elevated (E) is the elevated CO2 treatment.Plant root biomass and rootstock biomass in SC, MX and SP communities from 2000-2019 under control and elevated CO2 treatments, and mean biomass was calculated using R language. The table has 21 columns of data with biomass in g/m2. community is the sampling community, Chamber is the OTC facility number, Treatment is the treatment, Root is the root biomass, Rhizome is the rootstock biomass, A is the control treatment, and E is the elevated CO2 treatment. Fertilization effect of high CO2 on plant root biomass, rootstock biomass, and total belowground biomass in g/m2 from 2000-2019. elevated CO2 fertilization effect = biomass under elevated CO2 treatment - biomass under control treatment. community is the sampling community, Chamber is the OTC facility number, Treatment is the treatment, A is the control treatment, E is the elevated CO2 treatment, Root is root biomass, Rhizome is root biomass, and TotalBelow is total belowground biomass.
