…About half of the deep sea floor is covered by calcareous ooze, and the other half is covered by deeper sediments (mostly brown clays, but also some siliceous sediments) that contain 0 to a few percent CaCO 3. Bramlette calls the boundary between the two the carbonate compensation depth (CCD). At this depth, the supply and dissolution rates of CaCO 3 are equal. … From [Carbonate Compensation Depth]…About half of the deep sea floor is covered by calcareous ooze, and the other half is covered by deeper sediments (mostly brown clays, but also some siliceous sediments) that contain 0 to a few percent CaCO 3.

…深海底の面積の約半分は石灰質軟泥で，残りの約半分はより深い所にあってCaCO3を0～数％しか含まない堆積物(おもに褐色粘土，一部はケイ質堆積物)でおおわれている。ブラムレットM.N.Bramletteはこの両者の境の水深を炭酸塩補償深度(略称CCD)と呼んでいる。この深度ではCaCO3の供給率と溶解率は等しい。… 【炭酸塩補償深度】より…深海底の面積の約半分は石灰質軟泥で，残りの約半分はより深い所にあってCaCO3を0～数％しか含まない堆積物(おもに褐色粘土，一部はケイ質堆積物)でおおわれている。ブラムレットM.N.Bramletteはこの両者の境の水深を炭酸塩補償深度(略称CCD)と呼んでいる。この深度ではCaCO3の供給率と溶解率は等しい。… ※「CCD（海洋）」について言及している用語解説の一部を掲載しています。 出典｜株式会社平凡社世界大百科事典 第２版について | 情報 |
