We thought it was high time we checked in on Mossman's Yolly Bosiger who is embarking on one of the greatest adventures of her life as part of her ongoing work with the Underwater Scholarship Society Australasia.

Yolly has chronicled her experiences on a blog, and here's just a sample of what she has been up to.

In Palau with Tova Bornovski

I had also come to Palau to learn more about work of the Micronesian Shark Foundation and Tova Bornovski had generously agreed to host me and let me dive at her dive shop, Fish n’ Fins, which has got to be one of the most practical and well managed dive shops I have been to.

Having been in operation since 1972, it is also one of the most well established dive shops in Palau and employs over 20 local Palauan dive masters, boat captains and guides.

Tova had suggested that I visit Ongeim’l Tketau (also known as Jellyfish Lake), on my first day and after spending many an afternoon reading about this place in dive magazines, I was over the moon to be getting the opportunity to dive there.

I met Jade Rechelluul, my dive master and soon we were heading out of the harbor. We arrived at the island where we would find Jellyfish Lake and began our 10 min walk to the lake. The walk has recently been rebuilt by the Koror State government and is now a lot easier to negotiate with multiple pieces of camera gear.

We were told to swim to the sunny part of the lake as this is where the jellyfish would be taking advantage of the sunlight to photosynthesise.

Jellyfish lake has two species of jellies: the golden jelly, Mastigias papua etpisoni and the less common moon jelly, Aurelia sp. Like many coral species, golden jellys have developed a mutualistic relationship with microscopic algae (zooxanthelae) which converts sunlight into sugars for the jelly.

The golden jellyfish also capture zooplankton using stinging cells (nematocysts) on their arms. While their sting is much less severe then their lagoon ancestors (making the sting detectable to humans), the golden jelly is still able to actively capture small planktonic organisms using stinging cells.

I swam into the lake and could see 20 – 30 jellyfish in the vicinity. I kept swimming and swimming and then wow, their number just kept growing, more and more until they were positively thousands around me.

It was incredible and I had to be extremely careful so as to not hit them with my fins. Photographing the jellies was so much fun. They was so many of them so it didn’t matter if one jelly was misbehaving.

You could simply move on to the other 10 000 or so and considering that they weren’t going anywhere quickly, there was no urgency in the process. The only real challenge actually was processing the photos later.

Due to the ease of capture, I probably had almost as many photos as there were jellyfish and deciding between these was not the most exiting experience.
