Methane and Nitrous Oxide Budgets for Australasia: A Regional Assessment of Natural and Anthropogenic Sources and Sinks

Global Biogeochemical Cycles, Volume 39, Issue 10, October 2025.
Abstract We present the CH4 and N2O budgets for anthropogenic and natural sources and sinks of Australasia (Australia and New Zealand) from 2010 to 2019 using bottom‐up and top‐down methods, in line with the RECCAP‐2 initiative, with extensions to 2022.

Megathrust Earthquake Legacy Linked to Changes in Widespread Potential for Methane and Iron Cycling in Glaciated Wetlands

AGU Advances, Volume 6, Issue 5, October 2025.
Abstract Freshwater wetlands are major sources of global methane emissions through biogenic methanogenesis, a process increasingly influenced by climate change. High latitude wetlands are subject to uniquely altered biogeochemical inputs due to disproportionate warming.

Consumption of Methane and CO_2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea [PDF]

, 2007
The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor.

Dense bottom gravity currents and their impact on pelagic methanotrophy at oxic/anoxic transition zones [PDF]

, 2016
We show that inflows of oxygenated waters into sulfidic layers have a strong impact on biogeochemical transformation at oxic/anoxic transition zones. Taking the pelagic methane dynamics in the Gotland Basin as an example, we performed our studies when ...

The rise and fall of methanotrophy following a deepwater oil-well blowout [PDF]

, 2014
The blowout of the Macondo oil well in the Gulf of Mexico in April 2010 injected up to 500,000 tonnes of natural gas, mainly methane, into the deep sea1.

Modification and analysis of context-specific genome-scale metabolic models: methane-utilizing microbial chassis as a case study

mSystems
Context-specific genome-scale model (CS-GSM) reconstruction is becoming an efficient strategy for integrating and cross-comparing experimental multi-scale data to explore the relationship between cellular genotypes, facilitating fundamental or applied ...

Direct isotopic evidence of biogenic methane production and efflux from beneath a temperate glacier [PDF]

The base of glaciers and ice sheets provide environments suitable for the production of methane. High pressure conditions beneath the impermeable ‘cap’ of overlying ice promote entrapment of methane reserves that can be released to the atmosphere during ...

A biochemical framework for anaerobic oxidation of methane driven by Fe(III)-dependent respiration

Nature Communications, 2018
The unavailability of pure cultures has prevented a mechanistic understanding of anaerobic methanotrophy. Here the authors report a biochemical investigation of Methanosarcina acetivorans that supports a pathway anchored by Fe(III)-dependent mechanisms ...

Dating the cyanobacterial ancestor of the chloroplast [PDF]

, 2009
Cyanobacteria have played a pivotal role in the history of life on Earth being the first organism to carry out oxygenic photosynthesis, which changed atmospheric chemistry and allowed the evolution of Eukarya.
