The Big Burp: A Bad Day in the Paleocene [PDF]

open access: yes
This lesson focuses on global warming and a possible connection with the Paleocene extinction event. Students will explore how a global warming episode associated with the release of methane from methane hydrate deposits could have been responsible for ...

Search for impact ejecta at the Paleocene–Eocene boundary

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM).

Modern microbial landscape: Aerial mapping of microbially induced sedimentary structures forming in a coastal sabkha

open access: yesSedimentology, EarlyView.
ABSTRACT Microbially induced sedimentary structures (MISS) are considered important for understanding primitive life on Earth and for guiding the search for life on other planets. These structures are regarded as macroscopic fossils of early communities of unicellular organisms that did not produce skeletons or shells. In this study, field observations

Methane hydrate formation and decomposition

open access: yesElectronic Journal of Differential Equations, 2009
Methane hydrates, in arctic permafrost and deep ocean sediments, store vast amounts of methane, which is the primary constituent of natural gas and a potent greenhouse gas.

Tubular carbonate concretions as hydrocarbon migration pathways? Examples from North Island, New Zealand [PDF]

open access: yes, 2006
Cold seep carbonate deposits are associated with the development on the sea floor of distinctive chemosyn¬thetic animal communities and carbonate minerali¬sation as a consequence of microbially mediated anaerobic oxidation of methane.

CHECKING THE PRICE TAG ON CATASTROPHE: THE SOCIAL COST OF CARBON UNDER NON-LINEAR CLIMATE RESPONSE [PDF]

open access: yes
Research into the social cost of carbon emissions — the marginal social damage from a ton of emitted carbon — has tended to focus on “best guess” scenarios.
