(PhysOrg.com) -- A new study of an ocean sediment core taken from deep water off the coast of the western Antarctic Peninsula is beginning to fill in some of the gaps in our knowledge of climate variability in the region.
Although long thought to be devoid of life, the bottom of the deep ocean is now known to harbor entire ecosystems teeming with microbes. Scientists have recently documented that oxygen is disappearing from seawater circulating ...
