Dissolution of Calcite in the Twilight Zone: Bacterial Control of Dissolution of Sinking Planktonic Carbonates Is Unlikely
Figure 3
Representative electron micrographs of foraminifera shells incubated in dissolution experiment 2 (low nutrient treatment).
Upper row shows one foraminifera after 3 days incubation. Whole animal is represented in the left hand panel, the other 3 panels represent various random positions on the shell. The lower row represents similar pictures of a shell incubated in the same treatment for 28 days. Note the heterogeneity in shell condition. Both shells show areas of shell degradation, and areas of no degradation. Similar results were observed for all shells at all treatment levels.
