Thaum tshav ntuj nkag mus rau hauv dej, lub them nyiaj qhov tob sib txawv nrog dej hiav txwv tej yam kev mob. Piv txwv li, nrog kev nce hauv kev tsim khoom muaj kev nce hauv cov pejxeem phytoplankton, nrog rau cov naj npawb ntawm zooplankton uas noj phytoplankton.
Yog li ntawd, dab tsi hloov qhov nyiaj them qhov tob?
Thaum tshav ntuj nkag mus rau hauv dej, lub them nyiaj qhov tob sib txawv nrog dej hiav txwv tej yam kev mob. Piv txwv li, nrog kev nce hauv kev tsim khoom muaj kev nce hauv cov pejxeem phytoplankton, nrog rau cov naj npawb ntawm zooplankton uas noj phytoplankton.
Tom qab, lo lus nug yog, yuav ua li cas tshwm sim rau zooplankton hauv qab them nyiaj qhov tob? phytoplankton: Qhov tob ntawm phytoplankton txoj hauj lwm yog, qhov teeb pom kev tsawg dua nws tau txais. Thaum kawg, yog nws nyob hauv qab no tus them nyiaj qhov tob rau ntau tshaj li ob peb hnub, nws yuav haus nws cov carbohydrate reserves thiab tuag. kev faib ntawm plankton sib raug rau kev faib cov as-ham.
Hauv qhov no, dab tsi cuam tshuam rau carbonate them nyiaj qhov tob?
Carbonate them nyiaj qhov tob (CCD): Thermodynamics_Radwan Yog li ntawd, lub nyhuv ntawm ion concentration, siab, kub, thiab pH ntawm qhov sib sib zog nqus dej hiav txwv carbonate yuav tau tham. txhua yam uas txo cov concentration ntawm yaj CO2 yuav ua rau nag lossis daus ntawm calcium carbonate.
Dab tsi yog qhov nyiaj calcium qhov tob?
Hloov kho lub Cuaj Hlis 24, 2018. Carbonate Kev them nyiaj qhov tob , abbreviated li CCD, hais txog qhov tshwj xeeb qhov tob ntawm dej hiav txwv uas calcium carbonate cov zaub mov yaj hauv dej sai dua li lawv tuaj yeem khaws cia. Hauv qab ntawm lub hiav txwv yog them nrog nplua-grained sediment ua los ntawm ntau yam khoom xyaw.

Dab tsi yog ib txoj hauv kev uas koj tuaj yeem txo qhov kev sib txhuam ntawm ob qhov chaw?
Cov txheej txheem sib txawv tuaj yeem siv los txo qhov kev sib txhuam ntawm qhov chaw ntawm cov khoom hauv kev sib cuag. Ib txoj hauv kev los txo kev sib txhuam yog siv cov roj nplua nyeem rau qhov chaw, lwm qhov yog siv cov casters, rollers, lossis pob bearings nruab nrab ntawm qhov chaw, thiab lwm qhov yog ua kom du ntawm cov khoom hauv kev sib cuag
Qhov nruab nrab qhov tob ntawm CCD calcite them qhov tob yog dab tsi)?
Lub calcite them nyiaj qhov tob nyob nruab nrab ntawm 4 thiab 6 km hauv cov dej hiav txwv niaj hnub no thiab aragonite them nyiaj qhov tob (ACD) tshwm sim nyob rau nruab nrab ntawm li 3 km saum toj no (Morse thiab Mackenzie, 1990 thiab cov ntaub ntawv nyob rau hauv)
Dab tsi yog ob txoj hauv kev uas lub zog hluav taws xob ntawm ob qho khoom them tuaj yeem nce ntxiv?
Nyob rau hauv electrostatics, hluav taws xob quab yuam ntawm ob yam khoom them yog inversely cuam tshuam rau qhov kev ncua deb ntawm kev sib cais ntawm ob yam khoom. Ua kom qhov kev sib cais deb ntawm cov khoom txo qis lub zog ntawm kev nyiam los yog kev tawm tsam ntawm cov khoom
