Geomicrobioleg a Biogeocemeg
Rydym yn astudio’r rhyngweithio rhwng bywyd, daeareg a chemeg amgylcheddol i egluro prosesau biogeocemegol sy'n bwysig ar gyfer cyfanedd-dra’r Ddaear drwy gydol hanes y Ddaear.
Mae'r grŵp Geomicrobioleg a Biogeocemeg yn uno gwyddonwyr trawsddisgyblaethol ym meysydd microbioleg, bioleg a geocemeg.
Rydym yn ymchwilio i'r cysylltiadau rhwng geomicrobioleg a biogeocemeg i egluro prosesau biogeocemegol allweddol sy'n cynnal ecosystemau’n lleol ac yn fyd-eang.
Geomicrobioleg
Mae'r Uned Geomicrobioleg yn astudio ecosystemau amrywiol, o rai morol i rai daearol, o'r wyneb i'r biosffer morol a chyfandirol dwfn, sy'n rhychwantu'r Ddaear fodern i hynafol lle esblygodd bywyd.
Rydym yn defnyddio'r dystiolaeth i egluro sut mae bywyd microbaidd yn rhyngweithio â phrosesau daearegol, mwynau, metelau a’i gilydd i gynhyrchu a chynnal y prif gylchoedd biogeocemegol sy'n allweddol i gyfanedd-dra’r Ddaear.
Biogeocemeg
Rydym yn cyfuno arsylwadau geomicrobiolegol â geocemeg i ddatgloi hanes biogeocemegol y Ddaear. Mae'r gwaith amlddisgyblaethol hwn sy'n cysylltu’r Uned Geomicrobioleg â’r Uned Geocemeg, yn galluogi’r defnydd o ddulliau geocemegol cydraniad uchel ar gyfer ymchwilio i sut mae geomicrobioleg a geocemeg yn gweithio gyda'i gilydd yn yr amgylchedd.
Mae gan ymchwilwyr ddiddordeb mewn nodi a defnyddio signalau biogeocemegol fel procsis ar gyfer egluro sut mae bywyd yn rhyngweithio â geocemeg i greu a chynnal y biosffer byw.
