Nhasi tichataura nezverudzi rwegungwa rwakasiyana nedzimwe nzira. Zvayo ndezve tasman gungwa. Inowanikwa kumaodzanyemba kwenyika uye ine mamiriro ekunze akasiyana, pamwe nemaruva akasiyana siyana nemhuka. Iyi nharaunda inogona kuzivikanwa zvakajeka senge yekumaodzanyemba kwepasifiki bheseni rese. Iyo iri paMahombekombe eAustralia neNew Zealand inoshambidzwa neGungwa reTasman.
Munyaya ino tichaenda kukuudza zvese hunhu, kuumbwa, maruva uye mhuka dzegungwa reTasman.
Mhando huru
Pakamira gungwa iri rakasarudzika, nekuti nzvimbo ino yese inodarika akati wandei mamiriro ekunze. Mumwe mubvunzo unonakidza miganhu yawo. Ndiyo nzvimbo yekumaodzanyemba kwakadzika kwePacific Ocean basin. Kana tikatarisa pamepu, tinogona kuona gungwa iri sedhaimani hombe rinobatanidza makondinendi. Mune iri gungwa mune akawanda matombo emakorari, zviwi uye akakwirira kukwirira kwepazasi. Norfolk Island ndiyo nzvimbo yekuchamhembe pamuganhu pakati pemakungwa.
Gungwa reTasman rinoyevedza muhukuru se ine nharaunda inosvika 3.5 miriyoni mativi emakiromita. Kudzika kwaro zvakare. Chikamu chakadzama chegungwa iri chinozivikanwa seTasmanian basin uye chine hudzamu hwemamita zviuru zvitanhatu. Chitsuwa cheTasmania ndicho chakakurumbira mugungwa iri. Iyo iri pachitsuwa kumaodzanyemba kweAustralia anenge 240 km.
Iyi nharaunda yese iri geologically inoshanda. Vazhinji masayendisiti anga achiongorora ese magero maitiro anoitika munzvimbo idzi. Chinoonekera zvakanyanya muTasman Sea kupfuma kwezvinhu zvipenyu, zvirimwa nemhuka. Mhuka dzakasarudzika dzinowanikwa pano, inonyanya kuzivikanwa kuve Tasmanian dhiyabhorosi. Zvakare zvekutaura kuti ine yakawanda yemakorari matombo. Kune nzvimbo inozivikanwa seyecoral chitsuwa uye iri ibwe hombe iro zvinotora anenge mazana matanhatu emamita pamusoro pegungwa uye ingangoita mazana maviri emamita upamhi.
Vanhu vakasarudzika vemunharaunda vanowanikwa pachitsuwa cheTasmania chinogarwa nevanhu vashoma kwazvo. Semuenzaniso, Lord Howe Island ine vanhu vangori vanhu mazana mana. Ndicho chitsuwa chekaresa mukati megungwa iri rese. Pedyo nemhenderekedzo yegungwa tinowana mitsetse yakatsetseka munzvimbo yese. Mune mamwe emahombekombe emvura anowanikwa munzvimbo dzine jecha uye pakadzika peatombo, ivhu uye musanganiswa wezvose.
Mamiriro ekunze eTasman Sea
Tasman Sea yakawanikwa naAbel Tasman muna 1640. Saka izita rayo. Pakanga pasina ruzivo rwakawanda nezvegungwa iri makore apfuura. Vanhu vaisatomboziva kuti kuAustralia vaive kupi.
Nezve mamiriro ekunze, isu tine mutsauko mudunhu rese. Pakati peGungwa reTasman kune inodziya, inodziya uye inodziya mamiriro ekunze. Aya akasiyana mamiriro ekunze anoita kuti zvive nyore kukudziridza huwandu hwakawanda hwemiti nemhuka, zvichiita kuti ive nzvimbo yakasarudzika. Mamiriro ekunze anokanganisa mafungu egungwa anowanikwa pano. Masasi emhepo anopisa anotenderera nemumatunhu aya anoita kuti mvura isvike kusvika pamadhigirii makumi maviri nematanhatu. Muchikamu chekumaodzanyemba pane mvura inotonhorera nekuda kwekuswedera pedyo neAntarctica. Dzimwe hova dzine zvidimbu zvakakura zvechando sezvo tembiricha dzichidonha pasi pe zero pane dzimwe nguva dzegore.
Izvo zvinoitikawo nemasaisai. Kune mafambiro emvura anokwanisa kusvika pamamita mashanu. Izvo zvakare zvakasiyana maererano nehutongi hwematutu. Mhepo dzinobva kuPacific Ocean ndidzo dzinokonzera kuvepo kwemadutu aya. Kuwedzera kwetembiricha pamusoro pegungwa kunoita huwandu hwakawanda hwemhepo inodziya inosangana nemhepo inotonhora pakakwirira. Kana mweya unopisa uchisimuka wosangana nemhepo inotonhora pakukwirira, vanoguma vadzikama nekupa makore emvura. Nemusiyano wetembiricha yakasimba kwazvo dutu rinogona kutanga izvo zvinounza dzimwe njodzi dzemamiriro ekunze.
Kunyanya zvinofanirwa kucherechedzwa kuti pakati pe40-50 degrees latitude ndipo pane mukana wakakura wemadutu.
Gungwa reTasman nevagari
Isu tataura kuti iyo nzvimbo ine akati wandei enzvimbo dzemamiriro ekunze. Izvi zvinokonzera kukanganisa kune vanogara munzvimbo idzi. Ku kuchamhembe kune zvakakwana kudziya kuti kuve nenzvimbo dzinopisa. Kunyanya, zvinogona kuonekwa nekuda kwekuvapo kwehuwandu hwakawanda hwemhuka. Mune mamwe emhando dzatinowana, tinoona shark, hove dzinobhururuka uye zvipuka zvakawanda senge whale.
Huwandu hukuru hweshark marudzi anogara kumaodzanyemba kweTasman Sea. Muchena mukuru ndiye ane mukurumbira. Vashanyi vazhinji vanotya zvimbi zvaro zvakakura. Kufambiswa nemakeji nemidziyo yekudonha kunoitwa uchienderera mberi kucherechedza machena mashark. Kukwezva kwevashanyi kwakakosha kune mari yenharaunda yeTasman Sea. Kune rimwe divi, hove dzinobhururuka dzinoshamisa muhukuru, dzimwe nguva dzinosvika hafu yemita kureba. Inowanzo gara mumvura inodziya uye iine zvimbi zvina. Vanogona kusvetuka kubva mumvura pamusoro penzvimbo yakati rebei. Kureba kwekubhururuka pamusoro pegungwa kunoenderana nekumhanya kwemvura yemvura.
Kana iwe uchida kuona cetaceans muTasman Sea unofanirwa kuenda kuchamhembe chikamu. Tinogona kuwana sperm whale, matanda uye fin whale. Aya ma cetaceans anogara munzvimbo idzi nekuda kwekunyorova kwe zooplankton mumvura. Cetacean kuona ndeimwe yeanonyanya kufarirwa zviitiko zvevashanyi.
Flora nemhuka
Chekupedzisira, tichaenda kutaura nezve mamwe maruva nemhuka dzemarudzi. Algae inokura zvakanyanya munzvimbo yekuchamhembe uko mamiriro ekunze ari kudziya uye akaenzana. Anotonhorera masaisai haakanganisa kuwanda kwehove. Mhando dzakadai sa tuna, mackerel, Jorge, oga, pakati pevamwe, inowanzove iri.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve iyo Tasman Gungwa uye hunhu hwayo.
