Hidden biogeochemical anonymities under Antarctic Fast Ice
Shetye, S.S.; Mohan, R.; Patil, S.; Jawak, S.; Nair, Abhilash; Warrier, A.K.; Badnal, M.; Shirodkar, R. (2019)Climate change is negatively affecting the extent of summer sea ice and the global oceanic oxygen concentrations, it is therefore imperative to decipher the life processes under the Antarctic fast ice. The biogeochemical ... -
