I’m developing a new research initiative in the Quintana Roo marine protected areas: a passive acoustic monitoring system, using a series of underwater microphones, so we will be able to listen to, record, and analyze the sounds of fish, crustaceans, and other natural sounds, as well as motor boats and other forms of noise pollution. It is exciting to think about having the ability to continually track species/biodiversity and human use of the areas, and link patterns to specific events. This data will be of great help in informing managers of the areas about selecting the most appropriate measures to ensure the sustainability of the reef.
Passive acoustic marine monitoring equipment and reliable research methods are already being developed in other parts of the world, especially in Hawaii where NOAA has developed the Ecological Acoustic Recorder – check out http://www.pifsc.noaa.gov/cred/ear.php to learn more!

Last week marked the close of the sea turtle liberations in Cancun! People came out to participate even in the mess of rain we’ve been having. These were baby turtles, just hatched, brought from a different part of the beach where the eggs were being protected. Since turtles return to the same beach where they were born to lay their own eggs, the purpose of this program is to release the turtles in a suitable beach for them to return to later. How much later? Well, estimates are 15 to 50 years later is how long it takes them to reach reproductive maturity! Turtles can live over 100 years. Four main species are found here, the biggest of which is the Leatherback (Dermochelys coriacea). In spanish it is called Tortuga Laud or Lute Turtle, because it is sort of shaped like a lute!
