©2020 Biological and Chemical Oceanography Data Management Office.These data include counts of the sea urchin Diadema mexicanum for reefs off Pacific Panamá that were collected between 2016 and 2018. D. mexicanum individuals were counted for video transects that encompassed an area of 25 x 1 m. These data provide insight into the status of the sea urchin population and the amount of bioerosion pressure that these reefs are experiencing. The video transects were collected by students from Northeastern University's Three Seas Program and processed by Victor Rodr...

The abundance of sea urchins, which were predominantly Diadema mexicanum, were then used to estimate sea urchin density (ind. m-2).
