Tanya Atwater

Tanya Atwater, (an haife ta a shekara ta alif dari tara da arba'in da biyu miladiyya 1942) ita 'yar kasar Amurka ce kwararren masanin ilimin kimiya na kasa kuma kwararriyar ilimin kasa ta ruwa wacce ta kware a fannin tectonics. Ta shahara musamman don bincikenta na farko akan tarihin tectonic plate na yammacin Arewacin Amurka.

 Rayuwar farko da ilimi 
An haife Atwater a Los Angeles, California a shekara ta 1942. Mahaifinta injiniya ne kuma mahaifiyarta ƙwararriyar kimiya ce. Atwater na daya daga cikin matan farko da suka yi bincike a kan tekun ta fuskar Geology.
Atwater ta fara karatun ta a shekarar 1960 a Cibiyar Fasaha ta Massachusetts, sannan ta sami B.A. a Geophysics daga Jami'ar California, Berkeley a 1965. Ta sami digiri na uku. (1972) a cikin geophysics na ruwa daga Cibiyar Scripps na Oceanography, Jami'ar California, San Diego. Ita ce darekta na Jami'ar California, Santa Barbara Educational Multimedia Visualization Center inda ta kasance farfesa a fannin kimiyyar ƙasa. Ta kasance farfesa a Cibiyar Fasaha ta Massachusetts kafin ta shiga jami'a a UCSB a 1980. Atwater ya yi ritaya daga UCSB a 2007.

 Aiki 
Atwater ta kasa nce farfesa a fannin tectonics, a Sashen Kimiyyar Geological a Jami'ar California, Santa Barbara kafin ta yi ritaya. Ta rubuta tare da haɗin gwiwar rubuce-rubuce 50 a cikin mujallu na duniya, kundin ƙwararru, da manyan rahotanni. Bakwai daga cikin waɗannan takardu an buga su a cikin mujallu na Nature ko Kimiyya. A cikin 1975, ta zama Fellow of the American Geophysical Union don aikinta a fannin ilimin kimiyyar fasaha. Daga 1975 zuwa 1977, Atwater ya kasance mai karɓar Fellowship Fellowship Sloan a Physics. A cikin 1984, ta sami lambar yabo ta Ƙarfafawa daga Ƙungiyar Matan Masana Geoscientists. Atwater memba ce ta Kwalejin Kimiyya ta Kasa da aka zaba don gudunmuwarta ga ilimin geophysics na ruwa da tectonics. A cikin 2019 ta sami lambar yabo mafi girma na Geological Society of America, Penrose Medal.

 Binciken kimiyya 
Atwater ta kasance cikin balaguron balaguron teku ta hanyar amfani da zurfafan kida da aka ja don bincikar benen teku. Har zuwa yau, ta shiga cikin nutsewar ruwa mai zurfi 12 a cikin zurfin teku mai zurfi Alvin. Ta yi bincike kan hanyoyin tsaurin wuta-tectonic da ke da alhakin ƙirƙirar sabon ɓawon ruwa a wuraren shimfida saman teku. A cikin 1968, ta haɗu da rubuta takardar bincike da ke nuna aikin daɗaɗɗa a cikin ɓoyayyen yanayin yada cibiyoyin. Tare da Jack Corliss, Fred Spiess, da Kenneth Macdonald, ta taka muhimmiyar rawa a balaguron balaguron balaguron balaguro wanda ya gano nau'ikan ilimin halitta na maɓuɓɓugan ruwan teku, wanda ya haifar da ganowa yayin aikin RISE na masu yawan zafin jiki na masu shan sigari, iska mai ƙarfi ta ruwa.

A cikin binciken Atwater da ta yi kan yada baragurbi a kusa da tsibiran Galapagos, ta gano cewa an haifar da rarrabuwar kawuna a lokacin da ake yada cibiyoyi a bakin tekun da motsin tectonic ko magma ya dame shi, don haka sai da ta canza hanya don daidaitawa. Wannan ya taimaka wajen bayyana hadadden tsari na shimfidar teku.

Wataƙila an fi sanin Atwater da aikinta akan tarihin tectonic plate na yammacin Arewacin Amurka. Ta rubuta manyan takaddun bincike guda biyu da ke bayyana tarihin juyin halittar tectonic na Arewacin Amurka da matsalolin tectonic na San Andreas Fault, wanda ya taimaka wajen tattara tarihin Layin Laifin San Andreas.

Ta kuma yi nazarin juyin halitta na geometric, haɗawa da kwatanta bayanan motsin faranti na duniya tare da bayanan yanayin ƙasa na yanki. Ta sami alaƙar da ta kunno kai waɗanda suka bayyana asalin manyan fassarori masu girma dabam (misali Dutsen Rocky, Yellowstone, Death Valley, Cascade Volcanoes, California Coast Ranges).
Takardar bincike ta Atwater, "Tasirin Tectonics na Plate Tectonics ga Cenozoic Tectonic Juyin Halitta na Yammacin Arewacin Amirka", ya kafa mahimman tsari don tectonics farantin karfe na yammacin Arewacin Amirka. A cikin aikinta, ta bayyana cewa kimanin shekaru miliyan 40 da suka wuce, Farallon Plate yana raguwa a ƙarƙashin Plate na Arewacin Amirka da Pacific Plate. Ƙasar rabin farantin Farallon gaba ɗaya an rushe a ƙarƙashin Kudancin California kuma rabin na sama bai nutse ba, wanda a ƙarshe ya zama sananne da sunan Juan de Fuca Plate. Tunda kudancin yankin Farallon ya ɓace gaba ɗaya, iyakar kudancin California ta kasance tsakanin Plate Pacific da Plate na Arewacin Amurka. Laifin San Andreas na musamman ne saboda yana aiki azaman babban layin kuskure haka kuma yana iyaka tsakanin Plate Pacific da Plate ta Arewacin Amurka. Ta sabunta wannan aikin a 1989.Atwater, T.

Atwater tana sha'awar sadarwa da ilimi a kowane mataki. Ta haɓaka kafofin watsa labarai da yawa na lantarki (Cibiyar Kayayyakin Kayayyakin Kayayyakin Ilmi a UCSB) don haɓaka hangen nesa da fahimtar yanayin ƙasa, musamman masu alaƙa da tarihin faranti na tectonic.
