The effect of global climate change on Antarctic marine diatoms
Antarctic marine diatoms are sensitive to environment change. This project will determine the environmental niches occupied by key diatom species in Antarctic sediments. This will allow climate changes in the past to be interpreted from Holocene sediments and future changes in diatom biogeography to...
