Kushongedza Vesainzi uye Nharaunda
Iyo Ocean Foundation Inovaka sei Ocean uye Kugadzikana Kwemamiriro ekunze Kutenderedza Globe
Mupasi rose, gungwa riri kuchinja nekukurumidza. Uye pazvinoshanduka, zvipenyu zvemugungwa uye nharaunda dzinotsamira pazviri dzinofanirwa kuve nemidziyo yekuchinjisa.
Nzvimbo yesainzi yegungwa inodiwa kuti igone kudzikisira kunobudirira. Yedu Ocean Science Equity Initiative inotsigira masayendisiti, vanogadzira mitemo, uye nharaunda nekutarisa uye kuongorora shanduko yegungwa, kubatana nevadyidzani, uye kubatsira kudzika mutemo. Isu tinoshanda kufambisira mberi mutemo wepasirese uye masisitimu ekutsvagisa uye kuwedzera mukana kune maturusi anobvumira masayendisiti kunzwisisa nekupindura.
Isu tinoyedza kuona kuti nyika yega yega ine hurongwa hwakasimba hwekutarisa uye kuderedza, inotungamirwa nenyanzvi dzemuno kugadzirisa zvinodiwa munharaunda. Yedu Yekutanga nzira yatinobatsira nayo kuvaka sainzi, mutemo uye tekinoroji kugona kwevarapi pasi rese uye munyika dzavanogara.
GOA-ON muBhokisi
The GOA-ON muBhokisi ikiti ine mutengo wakaderera inoshandiswa kuunganidza mamiriro ekunze-mhando yegungwa acidification zviyero. Makiti aya akagoverwa kumasayendisiti munyika gumi nenhanhatu muAfrica, Pacific Small Island Developing States, neLatin America.
pCO2 kuenda
Gungwa riri kuchinja, asi zvinorevei kumarudzi anoridana kumusha? Uye zvakare, tinoita sei kune izvo zvatichanzwa semugumisiro? Panyaya yeocean acidification, oyster dzave zvese canary mumugodhi wemarasha uye kurudziro yekufambisa kugadzirwa kwezvishandiso zvitsva kutibatsira kugutsikana neshanduko iyi.
Muna 2009, varimi ve oyster kumahombekombe ekumadokero kweUS vakawana matambudziko makuru mumachende adzo uye muzvibereko zvekuzvarwa.
Iyo nascent ocean acidification research nharaunda yakatora nyaya iyi. Kupfurikidza nokucherekedza kwokungwarira, vakawana izvozvo hove dzechidiki dzine dambudziko vachigadzira matehwe avo ekutanga mumvura yegungwa pamhenderekedzo. Pamusoro pekuenderera mberi kwe acidification pamusoro pegungwa repasi rose, mahombekombe ekumadokero eUS - nekukwirisa kwaro kwemvura yakaderera pH uye acidification yemuno kunokonzerwa nekudya kwakawanda - ivhu rezero kune imwe yakanyanya kukosha acidification pasirese.
Mukupindura kutyisidzira uku, dzimwe nyuchi dzakatamira kunzvimbo dzakanaka kana kuti dzakaisa masisitimu ekuongorora makemikari emvura emhando yepamusoro.
Asi mumatunhu mazhinji pasirese, mapurazi ehove anopa chikafu nemabasa haawane maturusi anodiwa kurwisa mhedzisiro yegungwa acidification paindasitiri yavo.
Pinda dambudziko kubva kune Program Officer Alexis Valauri-Orton kuna Dr. Burke Hales, kemikemikari oceanographer anozivikanwa pasi rose pakugadzira OA monitoring systems: kuvaka inodhura-yakaderera, inobatwa nemaoko sensor iyo inobvumira kuti hatcheries kuyera kemikari yezvinouya. mvura yegungwa uye kuigadzirisa kuti iite mamwe mamiriro akanaka. Kubva ipapo ndipo pakaberekwa pCO2 to Go, sensor system inokodzera muchanza cheruoko uye inopa kuverenga nekukurumidza kwehuwandu hwekunyungudika kabhoni dhaimoni mumvura yegungwa (pCO2).
Mufananidzo: Dr. Burke Hales vanoshandisa iyo pCO2 Kuenda kunoyera huwandu hwekunyungudika kabhoni dhaokisaidhi mumuenzaniso wemvura yegungwa yakaunganidzwa kubva kumahombekombe egungwa pedyo neResurrection Bay, AK. Zvisikwa uye zvekutengesa-zvakakosha zvipenyu zvakaita se littleneck clams zvinogara munzvimbo ino, uye dhizaini yakabatwa nemaoko. pCO2 to Go inoibvumira kuti ifambe kubva pahatchery ichienda kumunda kuti itarise kuti ndezvipi zvipenyu zvirikusangana nazvo munzvimbo yadzinogara.
Kusiyana nemamwe masensa anobatwa nemaoko, akadai se pH metres, iyo pCO2 to Go inoburitsa mhedzisiro pane inodiwa chaiyo inodiwa kuyera shanduko dzakakosha mukemikari yegungwa. Nezvimwe zviyero zvishoma zviri nyore kuita, vanopfuya vanogona kudzidza zvirikusangana nehove dzadzo panguva ino uye votora matanho kana zvichidikanwa.
Imwe nzira iyo mahoko ehove anogona kubatsira nayo mahombe madiki adzo kuti ararame kubva padanho rekutanga rine njodzi ndeye “kuvharira” mvura yadzo yegungwa.
Izvi zvinopesana ne acidification yegungwa uye zvinoita kuti zvive nyore kuti magomba aumbe. Mhinduro dzebuffering dzinogadzirwa neresipi iri nyore-ku-kutevera inoshandisa zvidiki zve sodium carbonate (soda ash), sodium bicarbonate (iyo inoshanda musanganiswa mumapiritsi eAlka-Seltzer), uye hydrochloric acid. Aya ma reagents anoputsika kuita maion ayo atowanda mumvura yegungwa. Saka, iyo buffering mhinduro haiwedzere chero chinhu chisiri chisikirwo.
kushandisa pCO2 Kuenda uye nesoftware yerabhoritari, vashandi vekuhatchery vanogona kuverenga huwandu hwemhinduro yekuwedzera kumatangi avo. Nokudaro, zvisingadhuri kugadzira mamwe-akanyanya mamiriro ezvinhu akagadzikana kusvikira mvura inotevera ichichinja. Iyi nzira yakashandiswa neaya mahombe ekuzarisa akatanga kuona mhedzisiro yepH yakaderedzwa pamakonye awo. The pCO2 to Go uye mashandisirwo ayo anozopa ma hatchery ane zviwanikwa zvishoma nemukana mumwechete wekubudirira kurera mhuka dzadzo zvakanaka mune ramangwana. Maitiro ekuvharisa matangi, pamwe nemirayiridzo yemakesi akasiyana ekushandiswa kweiyi sensor nyowani, inosanganisirwa mubhuku rinoperekedza pCO2 Togo.
Mushandi akakosha mubasa iri ndiye Alutiiq Pride Marine Institute (APMI) muSeward, Alaska.
APMI inoronga yegungwa acidification sampling chirongwa uye inoyera sampuli dzakaunganidzwa muNative Village mhiri kwakadziva pakati peAlaska pane inodhura tabletop chemistry chiridzwa chinonzi Burke-o-Lator. Achishandisa chiitiko ichi, maneja werabhu Jacqueline Ramsay akatungamira bvunzo dze sensor uye iyo yakabatana app, kusanganisira kuenzanisa sampuli tsika neBurke-o-Lator kuratidza kana kusavimbika kwekuverenga kwakawanikwa ne pCO2 kuenda kuri mukati mechikamu chaunoda.
Mufananidzo: Jacqueline Ramsay, maneja weAlutiiq Pride Marine Institute's Ocean Acidification Research Laboratory, anoshandisa pCO2 kuenda kunoyera huwandu hwekabhoni dhaikisaidhi mumuenzaniso wemvura inounganidzwa kubva muhurongwa hwemvura yegungwa. Jacqueline mushandisi ane ruzivo rweBurke-o-Lator, chiridzwa chakanyanya-chaizvo asi chinodhura zvakanyanya chekuyera kemikari yemugungwa, uye yakapa mhinduro yekutanga pakuita kwePC.2 Kuenda kubva kune ese maonero evashandi vehatchery pamwe nemuongorori wemakemikari wegungwa.
TOF inoronga kuendesa iyo pCO2 Kuenda kunzvimbo dzinozarirwa nyuchi pasi rose, zvichipa nzira isingadhuri kuti maindasitiri ari munjodzi yehove arambe achigadzira magoko madiki zvisinei nekuwanda kweasidhi. Kuedza uku kushanduka kwechisikigo kweGOA-ON yedu muBhokisi Kit - mumwe muenzaniso wekuunza zvemhando yepamusoro, zvisingadhuri zvekushandisa kuitira kuti vatinonamata navo vanzwisise uye vapindure kune acidification yegungwa.
