Methane formation in tropical reservoirs predicted from sediment age and nitrogen by Isidorova, Anastasija, Grasset, Charlotte, Mendonça, Raquel, Sobek, Sebastian

“…Freshwater reservoirs, in particular tropical ones, are an important source of methane (CH 4 ) to the atmosphere, but current estimates are uncertain. The CH 4…”
