Kua oti i te kamupene Amerikana a TDI-Brooks tētahi kaupapa rangahau nui i waho o Niu Ioka me Niu Herehi. I waenganui i a Hanuere 2023 me Pēpuere 2024, i whakahaerehia e te kamupene tētahi kaupapa rangahau whānui i ngā pāmu hau e rua i waho o te moana i ngā wai o te kawanatanga me te kāwanatanga.
I mahia e TDI-Brooks ngā mahi maha pērā i ngā rangahau matawhenua, ngā rangahau UHRS taipitopito, ngā rangahau tautuhi whaipara tangata, te keri whenua māmā me te kohi tauira mo te papa moana i ngā wāhanga rerekē.
Kei roto i ēnei kaupapa te rangahau i ngā kiromita rārangi neke atu i te 20,000 o ngā rīhi rū whenua kotahi-me te maha-hongere me ngā taura i te takutai o New York me New Jersey.
Ko te whāinga, i whakatauhia mai i ngā raraunga kua kohia, he aromatawai i te āhua o te papa moana me te moana, tae atu ki ngā mōrearea pea (ngā mōrearea whenua, ngā mōrearea i hangaia e te tangata) ka pā ki te tāutanga o ngā tāhū hau me ngā taura raro moana ā muri ake nei.
E toru ngā waka rangahau i whakahaerehia e TDI-Brooks, arā, ko te R/V BROOKS McCALL, ko te R/V MISS EMMA McCALL me te M/V MARCELLE BORDELON.
I roto i te rangahau hangarau whenua, i kohia he 150 ngā Pneumatic Vibratory Cores (PVC) me te neke atu i te 150 ngā Neptune 5K Cone Penetration Tests (CPT) i te rohe rīhi me te Offshore Cable Track (OCR).
I te taha o te rangahau i ētahi ara taura putanga, i whakahaerehia he rangahau tirotiro e kapi ana i te rohe rīhi katoa me ngā rārangi rangahau i wehea i te 150 mita te tawhiti, ā, i whai ake ko tētahi rangahau whaipara tangata taipitopito ake i te 30 mita te tawhiti.
Ko ngā pūoko whenua e whakamahia ana ko te Dual Beam Multibeam Sonar, te Side Scan Sonar, te Seafloor Profiler, te UHRS Seismic, te Single Channel Seismic Instrument me te Transverse Gradiometer (TVG).
E rua ngā wāhanga matua i hipokina e te rangahau. Ko te wāhanga tuatahi ko te ine i ngā panonitanga o te hohonutanga o te wai me ngā paripari, te ako i te āhua (te hanganga me te āhua o ngā hanganga o te papa moana i runga i te whenua o te rohe), te tautuhi i ngā arai taiao, arai hanga-tangata rānei i runga, i raro rānei i te papa moana pērā i ngā pari toka, ngā awaawa, ngā rua, ngā āhuatanga wai hau, ngā para (taiao, hanga-tangata rānei), ngā para, ngā hanganga ahumahi, ngā taura, me ētahi atu.
Ko te arotahi tuarua ko te aromatawai i ngā tūponotanga matawhenua o te wai pāpaku ka pā pea ki ēnei wāhi, me ngā rangahautanga matawhenua hōhonu a meake nei i roto i te 100 mita o te papa moana.
I kī a TDI-Brooks he mea nui te kohikohi raraunga ki te whakatau i te wāhi me te hoahoa tino pai mō ngā kaupapa taiwhenua pēnei i ngā pāmu hau.
I te marama o Pēpuere 2023, i pūrongo te kamupene kua riro i a ia tētahi kirimana mō ngā rangahau matawhenua, hangarau matawhenua me te tango tauira mo te papa moana hei ako i ngā āhuatanga o te papa moana i roto i te rohe riihi kaupapa me ngā huarahi taura kaweake pea i waho o te Tai Rāwhiti o Amerika.
I roto i ētahi atu purongo mai i TDI-Brooks, i tae mai te waka rangahau hou a te kamupene, a RV Nautilus, ki te Tai Rāwhiti o Amerika i te marama o Poutū-te-rangi whai muri i te whakahoutanga. Ka whakahaerehia e te waka ngā mahi hau moana ki reira.
Ka mahi tahi a Damen Shipyards me ngā kaiwhakahaere o te umanga pūngao moana huri noa i te ao. Nā te mātauranga me te wheako i riro mai i te mahi tahi tata me te mahi tahi mō te wā roa, kua hua ake he kohinga kaha o ngā kaipuke iti me te rahi waenga e tutuki ana i te huringa ora moana katoa me te arotahi ki te pūngao whakahou. Ko te hoahoa paerewa me ngā wāhanga modular e whakarato ana i te […]
