Documenting the marine lakes of Palau using a drone

Palau has a huge number of Marine Lakes locked within it’s limestone islands and I’ve wanted to explore them since I’ve been here but they are very hard to get to, usually surrounded by thick jungle growing out of razor sharp rocks.

Because of this few people have managed to explore them so I thought I would use a drone to take a look and see them from a new perspective. Aircraft such as planes and helicopters have of course flown over them but I don’t think anyone has actually descended into one before.

So I used Google Earth to locate a few that were 1 mile or less from a suitable take off point and set to flying over and into them.

Some are impressive like the one in the video above, others no more than a depression with some shallow water in that dries quickly without rain.

What are Marine Lakes?

Marine lakes form in limestone islands  where certain areas of the limestone erode away quicker than their surroundings. This erosion can create a depression or bowl and if that bowl is close enough to the ocean it may fill with sea water percolating through the porous limestone.

What makes Palau’s Marine Lakes special is that sometimes in a few places certain organisms such as Jellyfish have flowed in and remained there.

Some have nothing living in them but maybe frogs, others can have millions of Jellyfish. I’m looking forward to the day I spot one of Palau’s Saltwater Crocodiles……

After months of recon flights over one particular lake, I decided to find a way to film what was inside it. A little local know how told me a route and one day I set off to film there. See this film here for my findings……

The Marine Lake environment is extremely fragile but incredibly interesting. For further reading consider this article.
