High concentrations of exopolymeric substances in wintertime sea ice: Implications for the polar ocean carbon cycle and cryoprotection of diatoms
-
This study of winter sea-ice cores shows that the ice is filled throughout with high concentrations of exopolymeric substances (EPS). At winter-ice temperatures to as low as -20°C, EPS were observed to protect organisms within the ice against physical damage by encroaching ice crystals.

Volcanoes, fluids, and life in submarine environments
-
This major review paper looks at processes in the mantle to the hydrosphere in the context of impacts on microbial communities. Much of the information is directly relevant to astrobiological questions concerning the flux of volatiles, heat sources and linkages to microbial processes. This paper is being used by numerous upper undergraduate and graduate classes in a textbook fashion.

4 in the atmosphere of early Earth
-
Physics indicates that the Sun was about 30% less luminous 4 billion years ago, so Earth's ancient atmosphere must have had higher concentrations of greenhouse gases so that the Earth was not permanently frozen. During the 1980s and 1990s it was widely hypothesized that Earth's early atmosphere had very large levels of carbon dioxide. This view has now been largely abandoned; Pavlov and colleagues show how biogenic methane would build up in an early anoxic atmosphere and operate as the key greenhouse gas.

A new phylum of Archaea represented by a nanosized hyperthermophilic symbiont
