Thirty years of arctic primary marine organic aerosols: patterns, seasonal dynamics, and trends (1990–2019) [PDF]
Atmospheric Chemistry and PhysicsChanging Arctic climate conditions have accelerated sea ice retreat, altering ocean–atmosphere interactions and marine ecosystems. Reduced sea ice cover likely enhances emissions of primary marine organic aerosol (PMOA) through bubble bursting, with ...

Erratum to: A novel pmoA lineage represented by the acidophilic methanotrophic bacterium Methylocapsa acidophila B2 [PDF]
Archives of Microbiology, 2001 A fragment of the functional gene pmoA, which encodes the active-site polypeptide of particulate methane monooxygenase (pMMO), was PCR-amplified from DNA of the recently described acidophilic methanotrophic bacterium Methylocapsa acidophila B2. This methanotroph was isolated from an acidic Sphagnum peat bog and possesses a novel type III arrangement of

Identification of Novel Methane-, Ethane-, and Propane-Oxidizing Bacteria at Marine Hydrocarbon Seeps by Stable Isotope Probing [PDF]
, 2010 Marine hydrocarbon seeps supply oil and gas to microorganisms in sediments and overlying water. We used stable isotope probing (SIP) to identify aerobic bacteria oxidizing gaseous hydrocarbons in surface sediment from the Coal Oil Point seep field ...
