Dataset: Internal carbonic anhydrase activity in three species of coral collected from the Florida Keys in August 2013

Fragments of Orbicella faveolata, Porites astreoides were collected from Little Grecian reef (25.1193 N 80.3008 W) and Siderastrea radians was collected from Florida Bay (25.1017 N, 80.4391 W) in Key Largo, FL, USA, in August of 2013 as permitted by the Florida Keys National Marine Sanctuary (FKNMS-2011-093, FKNMS-2014-015). Exposed skeleton was covered with modeling clay, and the colonies were maintained in closed circulation tanks filled with reef seawater, allowing at least 2 days of recovery after collection prior to experimentation. The tank was exposed to a natural light regime, with shading added at midday to keep solar irradiance below 600 umol photons m−2 s−1.
