海洋碳封存示意图根据文献[ 4 , 8 , 17 ]修改 a和b：将CO 2 注入到浅至中层时, CO 2 具有浮力;c：当CO 2 注入深度大于3 000 m时, 因其密度比海水大而下沉, 形成碳湖;d：注入密度大于海水的、由CO 2 水合物与海水组成的膏状混合物;e：将CO 2 注入至HFZ带;f：将CO 2 注入至HFZ带与NBZ带的叠合区
Schematic diagram illustratingthe carbon sequestration in oceansmodified after references [ 4 , 8 , 17 ] a and b: CO 2 is injected into the shallow-intermediate layer, where it is buoyant; c: CO 2 is injected into the layer with the depth of more than 3 000 m, where CO 2 is denser than seawater, and it will sink to form a lake; d: a paste-like and denser-than-seawater composite of CO 2 hydrate and seawater is extruded; e: CO 2 is injected into the HFZ zone; and f: CO 2 is injected into the HFZ and NBZ zones.
