A recent study shows how ancient groundwater beneath the ocean floor may have interacted with ice sheets and rising sea levels during past climate changes. Fossil groundwater may have been influenced by dramatic changes in sea level and the movement of massive ice bodies. Although previous studies suggest that deep groundwater flow could help destabilise ice sheets or accelerate their melting, there has been very little direct evidence from the field to support these ideas until now, according to the researchers.
