Black carbon (BC) is produced by incomplete combustion of biomass by wildfires and
burning of fossil fuels. BC is environmentally persistent over centuries to millennia …

Gas hydrate, a frozen, naturally‐occurring, and highly‐concentrated form of methane,
sequesters significant carbon in the global system and is stable only over a range of low …

The leakage of cold, methane-rich fluids from subsurface reservoirs to the sea floor at
specific sites on continental slopes, termed cold seeps, sustains some of the richest …

Although initially viewed as oases within a barren deep ocean, hydrothermal vents and
methane seep chemosynthetic communities are now recognized to interact with surrounding …

Methane seeps are widespread seafloor ecosystems shaped by the emission of gas from
seabed reservoirs. The microorganisms inhabiting methane seeps transform the chemical …

More than 90% of the global ocean dissolved organic carbon (DOC) is refractory, has an
average age of 4000–6000 years and a lifespan from months to millennia. The fraction of …

We first review dissolved organic matter (DOM) concentrations and isotopic composition
(carbon only) in sediment pore waters at both the bulk level and at the compound and …

Marine dissolved organic matter is a massive reservoir of carbon holding> 200x the ocean
biomass inventory. Primarily produced at the ocean surface and then exported to depth with …

Marine dissolved organic carbon (DOC) is a large (660 Pg C) reactive carbon reservoir that
mediates the oceanic microbial food web and interacts with climate on both short and long …

The last decade of Mars exploration produced a series of discoveries that provide
compelling evidence for the existence of sedimentary rocks on Mars. Previously, Mars was …
