Gas hydrate pingo

gas hydrate pingo wani tsari ne na karkashin ruwa wanda aka kafa ta hanyar tara gas hydrates a ƙarƙashin teku.

 Tsarin da Wuri 
Gas hydrate pingos suna dauke da tankuna na gas hydrates, wanda shine ƙwayoyin gas. Kwayoyin gas ɗin da aka ƙera sun samo asali ne lokacin da kwayar gas ke kewaye da kwayoyin ruwa. Kwayoyin ruwa suna haifar da Tsarin lattice wanda ke rufe kwayar gas lokacin da zafin jiki da matsin lamba (kimanin megapascals 15).  Yawancin gas hydrates suna dauke da methane, yayin da wasu rare gas hydrates ke dauke da hydrogen sulfate ko carbon dioxide. Ana samun waɗannan pingos na ruwa a gefen nahiyar da kuma yankuna masu zafi, musamman a wuraren da ke da methane. Wadannan wurare galibi suna da permafrost wanda ke ƙasa da matakin teku, amma wannan permafrest ba a buƙata don samar da gas hydrate pingo. Misali na waɗannan hanyoyi daban-daban na samar da pingo za a iya samun su a bakin tekun Angola, wanda aka kafa daga magudanar methane, da kuma Yammacin Svalbard Margin, wanda aka samo daga sub-sea permafrost. Sauran misalai na gas hydrate pingos za a iya samun su tare da gefen Chilean da Brazil.

 Tasirin Yanayi da Muhalli 
An yi nazarin gas hydrates a matsayin yiwuwar nau'in makamashi mai tsabta, saboda suna iya zama ƙarin tankunan gas na halitta. Koyaya, yayin da zafin jiki na duniya ke ƙaruwa, waɗannan iskar gas sun zama marasa daidaituwa, ma'ana cewa za su iya fitar da iskar gas a cikin yanayi kuma su ba da gudummawa ga dumamar duniya. Gas hydrate pingos na iya zama marasa daidaituwa saboda babban aikin girgizar ƙasa a kusa da su, tunda waɗannan tsari galibi suna tare da gefen nahiyoyi da sauran wuraren sha'awar girgizar kasa.

Gas hydrate pingos da yankunan da ke kewaye da su sune rundunonin kwayoyin halitta daban-daban, gami da nau'ikan tsutsotsi na ruwa, mussels, clams, snails na ruwa, shrimp da ƙwayoyin cuta. Yawancin waɗannan kwayoyin suna yin methanogenesis a matsayin nau'in numfashi na anaerobic. Wani bincike a cikin Tekun Norway ya gano cewa an rufe pingos na gas hydrate da mats na kwayoyin cuta da Polychaete tubeworms waɗanda ke da alaƙa da methane.
