Prokaryotic life has dominated most of the evolutionary history of our planet, evolving to
occupy virtually all available environmental niches. Extremophiles, especially those thriving …

Natural gas hydrates occur worldwide in polar regions, normally associated with onshore
and offshore permafrost, and in sediment of outer continental and insular margins. The total …

Diverse microbial communities and numerous energy-yielding activities occur in deeply
buried sediments of the eastern Pacific Ocean. Distributions of metabolic activities often …

This study examines thermal and structural controls of the updip and downdip rupture limits
of great subduction thrust earthquakes. Data on past great earthquake seismic limits have …

Water‐rock interactions within the seafloor are responsible for significant energy and solute
fluxes between basaltic oceanic crust and the overlying ocean. Permeability is the primary …

The Mediterranean basin is sensitive to global sea-level changes and African monsoon
variability on orbital timescales. Both of these processes are thought to be important to the …

We have used drilling and downhole logging results (from Deep Sea Drilling Project holes
395A and 418A), measured properties of core samples from the seafloor and from …

Mediterranean sediments are valuable archives of both African monsoon variability and
higher-latitude climate processes, and can also be used to provide an environmental context …

Sedimentary basin inversion, the shortening of formerly extensional basins, is
accommodated mainly by compressional reactivation of extant faults and fractures across a …

The organic carbon cycle on Earth is divided into two parts (Fig. 4.1; Tissot and Welte 1984).
The biological cycle starts with photosynthesis of organic matter from atmospheric carbon …
