Blue Planet II is a documentary series produced by the BBC Natural History Unit, presented and narrated by David Attenborough which explores de planet’s oceans; the filming of the documentary series was done over the course of four years and involved 125 expeditions across 39 countries, one of these was Costa Rica.

Costa Rican photographer Sergio Pucci was the person in charge of filming the wonderful phenomenon of the arribadas (arrival) of olive ridley sea turtles (Lepidochelys olivacea) at the National Wildlife Refuge Ostional in Guanacaste.

The complex work was done between 2015 and 2016, “During those two years we made four attempts before reaching the final shoot. We made several attempts because either the arribada wasn’t massive or the peak was at times of extreme darkness, or a person or an animal would interrupt the filming which caused many shots to be ruined. Shots had to be perfect due to the prestigious production we were working with, a documentary that has already been released in London, England”, explained Pucci in an interview with daily La Nacion.

Pucci is one of the creator of the books and productions Costa Rica Aerea I and II.

Blue Planet II will be premiered in Latin America in 2018. The shots of Ostional were included in the sixt episode of the documentary, entitled Coasts. This documentary is considered one of the best marine documentaries in history.
