It's our regular one-day dive trip combined with Coral Watch and underwater cleanup activities.

We will be specifically conducting observation on the development of crown of thornes around the Karang Lebar area of Pulau Semak Daun. If the presence of COTs increased significantly, we will remove them to avoid further expansion and threat of coral bleaching.

As usual, we will collect underwater debris in every dive. Let's make our underwater planet cleaner and join the Aware Scavenger Hunt game :)


As scheduled, on June 19-20, 2011 we made a trip with a group of kids and parents from the High/Scope Indonesia school. The trip which has been prepared in about a month was named: "High/Scope Mums & Kids Goes To Pulau Seribu, Protecting The Ocean One Little Step at A Time".

The trip was joined by 4 pre-schoolers (3 years old) and 2 elementary grade students, plus their parents. They are:


We are monitoring the presence of Crown of Thorne (COT) around the Jakarta Bay, especially within the vicinity of Pulau Pramuka and Pulau Semak Daun.

In the past three months we observed that the number of COTs has been increasing quite significantly. In February 2011, at our observation block of Karang Lebar, northwest of Pulau Semak Daun, there were three (3) COTs inside a 100-square meter of reef. By April, this number increased to six (6) COTs at the same spot.
