Correction: Biodiversity on the Rocks: Macrofauna Inhabiting Authigenic Carbonate at Costa Rica Methane Seeps.

Fig 2, “Temperature and dissolved oxygen profile generated near Jaco Wall, Costa Rica from a CTD cast,” is incorrect and is a duplication of Fig.1, “Carbonates formations in different habitats on the Costa Rica Margin.” The authors have provided a corrected version here.

Fig 2

Temperature and dissolved oxygen profile generated near Jaco Wall, Costa Rica from a CTD cast.

Fig 11 is incorrect. Panels A and B were inadvertently switched. Panel B should be Panel A, and Panel A should be Panel B. The authors have provided a corrected version here.

Fig 11

A. Dual isotope plot for polychaetes collected from carbonates on Mound 11 and 12 during AT 15–44. Costa Rica; B. Dual isotope plot for six limpet species collected on a single rock on Mound 12. In both figures each point represents a single individual.

There are errors in Table 6. The mean range columns have errors in the column titles. The authors have provided a corrected version here.
