Chidzidzo chakaitwa nevanoongorora kubva Yunivhesiti Institute of Water Research uye Dhipatimendi reEcology ye Universidad de Granada Zvinoratidza kuti mupiro weguruva kubva kuSahara Desert unokwanisa kuwedzera basa reGungwa reMediterranean se CO2 kunyura.2.
Chii chinonzi CO sink?2? Iyo inzvimbo iyo inokwanisa kubata CO2 kubva mumhepo uye kwete kuidzosera kutenderera zvakare, asi kuti CO2 inosiya kutenderera kwemhepo.
Tsvakurudzo iyi, yakaitwa mukati meprojekti ZVINANGWA, inoratidza kuti Gungwa reMediterranean rinoita seCO sink2 mhepo munzvimbo dzegungwa rakashama. Iyo ine basa rekubvisa CO2 yekutenderera munzvimbo idzi, asi inoshanda senzvimbo yeCO2 pamahombekombe, kwainokwanisa kuigadzira. Hunyambiri uhwu hwakakosha kuti unzwisise kukosha kweMediterranean sekunyura uye sosi yeCO2.
Zvichienderana nekuwanikwa uku, kuedza kwakaitwa kuratidza kuti idzi ecosystems dzinoshanda seinonyura uye masosi eCO.2 vaizopindura kuwedzera guruva rinopinda kubva kuSahara uye kune ultraviolet radiation. Kukosha kwekuedza mhinduro yezvipenyu izvi kune izvi zvakasiyana-siyana zviri mukuti ndizvo zvakakosha zvekuchinja kwepasi rose kunobata nzvimbo yeMediterranean.
Mhedzisiro yekuedza kwakaitwa in situ Vanoratidza kugona kunoita algae kukwanisa kubata CO2 kubva mumhepo uye saka ita sedhishi. Munyori wemushumo uyu, Marco Jabalera Cabrerizo, anoshanda muDhipatimendi reEcology paYunivhesiti yeGranada.
Muongorori akasimbisa kuti mumakumi emakore apfuura, kupindira kweguruva reSahara pamwe nekuwedzera kwekusangana nemwaranzi ye ultraviolet kunogona kuwedzera. Basa reGungwa reMediterranean semutongi we CO2 mazinga2 munguva pfupi iri kutevera. Ichi ndicho chikonzero migumisiro yezvidzidzo izvi yakakosha zvikuru kana tikazviisa mumamiriro ezvinhu ekuchinja kwemamiriro ekunze, sezvo vanogona kutitaurira kana zvipenyu zvegungwa zvichaita se CO2 inonyura.2 kana semanyuko mune ramangwana. Mukuwedzera, zvakakosha kufunga kuti sei kupisa kwepasi pose inokanganisa maitiro aya.
Basa reguruva reSahara mune kabhoni cycle
Guruva rinobva mugwenga reSahara, kana richitakurwa nemhepo richienda kuGungwa reMediterranean, rinogona kuva nemigumisiro yakawanda pazvipenyu zvegungwa. Iri guruva haringopi zvinovaka muviri zvakakosha senge phosphorus nesimbi, izvo zvinodiwa pa photosynthesis, asi zvinogona zvakare kushandura kemikari yemvura uye nokudaro zvinokanganisa kugona kwegungwa kutora CO.2. Kuti unzwisise zviri nani kuti maitiro aya anoshanda sei, zvakakosha kuziva kuti sei Mamiriro ekunze eMediterranean inodyidzana nemasimba aya.
Chiitiko ichi, chinozivikanwa se kudyidzana kwegungwa, inogona kuwedzera kukura kwe phytoplankton, iyo inozoita basa rakakosha mukutorwa kwekabhoni. Saka, algae inoshandisa CO2 nokuda kwephotosynthesis, kuderedza kunyura kwayo mumvura uye kuwedzera kutorwa kwayo kwegasi kubva mumhepo. Zvinokosha kuziva kuti, maererano nemaitiro aya, chidzidzo pa Marine ecosystem uye basa radzo mukushanduka kwemamiriro ekunze Zvakakosha kunzwisisa basa rayo.
Zvisinei, kuwedzera kweguruva kunopinda kunogonawo kuva nemigumisiro yakaipa. Semuenzaniso, shanduko mu acidity yemvura inogona kukanganisa hutano hwezvipenyu zvemugungwa zvinoenderana nekemikari yegungwa, saka zvakakosha kudzidza kuti Mediterranean iri panjodzi yekushanduka kwemamiriro ekunze..
Mhedzisiro yeongororo yeMETAS
Tsvagiridzo yepurojekiti yeMETAS yakaratidza kuti Gungwa reMediterranean rinoita nenzira mbiri, kuve a CO sink2 mugungwa rakashama uye tsime munzvimbo dzemahombekombe. Kuwanikwa uku kwakakosha pakunzwisisa maitiro eecosystem pakatarisana nekushanduka kwemamiriro ekunze.
Kuratidzwa kune ultraviolet (UV) mwaranzi uye kusiyanisa muguruva intrusions kunokanganisa kugona kwealgae kutora CO.2. Munguva yekuyedza, zvakaonekwa kuti yakawedzera UV mwaranzi yakaderedza kugona kwephotosynthesis mune mamwe marudzi ealgae, ayo anogona kukanganisa basa rawo semanyura ekabhoni. Izvi zvinoburitsa kukosha kwekuferefeta kuti sei Kuchinja kwemamiriro ekunze kunokanganisa zvipenyu izvi.
Mhedzisiro yekushanduka kwemamiriro ekunze muMediterranean
Kuchinja kwemamiriro ekunze kuri kukonzera kuwedzera kwekushisa kwemvura yeMediterranean, izvo zvinozokanganisa maitiro emvura uye kuwanda kwemafungu ekupisa. Shanduko idzi dzinogona kukanganisa zvakanyanya marine biology uye chemistry yemvura. Uyezve, sezvo kutenderera kwekabhoni kwakakosha, zvinonakidza kuona kuti sei zvinomera zvinoenderana nekushanduka kwemamiriro ekunze.
Kukwira kwetembiricha kunogonawo kubatsira mukuwedzera kuburitsa CO2.2 kubva mugungwa kuenda muchadenga, zvichigadzira kutenderera kunotyisa kunowedzera kudziya kwepasi. Naizvozvo, tsvakiridzo munharaunda iyi haina kukosha chete kuti unzwisise mashandiro eCO2, asiwo kufanotaura mamiriro ekunze emamiriro ekunze. Nezvenyaya iyi, chidzidzo chiri pa the heat island effect inonyanya kukosha kune ramangwana rekufungidzira.
