Podcasts - online distributed audio files are easy access and production media, which can be used for Scientific Communication (SC) but few presented in Portuguese. The objective of this work is to perform a case study with data from survey two Brazilian SC podcasts (Dragões de Garagem Fronteiras da Ciência) evaluate the increase science podcast media Brazil, involved potential, their advantages, shortcomings, perspectives. We noted an listeners over years, probably due internet...
The basal environments of ice sheets play an important role as places methane (CH4) production, storage, and release. Recent investigations have confirmed the release subglacial microbial origin at western margin Greenland Ice Sheet (GrIS). This may then serve a substrate for methane-consuming microorganisms thus significantly shape community assembly in GrIS environments. We conducted comparative analysis composition exported assemblages from six regions spanning 2,000-km transect along...
Recent studies have shown the release of methane (CH4) from melting Greenland Ice Sheet (GrIS) and identified it as having an additional potential positive climate feedback. This originates mainly acetoclastic methanogenesis in subglacial sediments, accumulates over time, subsequently diffuses into hydrologic network which transports to ice sheet margin. The rates production emission GrIS sediments likely depend on a number factors, including sediment depth distribution, organic matter...
Recent research underscores a potential, yet overlooked, positive climate feedback mechanism: the transport of subglacially produced methane (CH4) to atmosphere via meltwater. While majority focused on release from beneath Greenland Ice Sheet, mountain glaciers have been largely understudied, creating gap in our understanding spatial distribution subglacial CH4 emissions. Emerging Iceland, Canada, Alaska, and China suggests presence also other than Sheet.   Here, we explore...
 Recent studies have shown the release of methane (CH4) through melting Greenland Ice Sheet, and thus identified it to an additional potential positive climate feedback. This CH4 is thought originate from biologically active methanogenic ecosystems in subglacial sediments, where microbes produce by converting overridden organic carbon CH4, which then accumulates over time. Subsequent diffusion into hydrologic network transports ice sheet margin, directly emitted atmosphere...
