Our Snorkelling and Diving Day at Silfra, Iceland in August 2014 (summer)

Located in the Þingvallavatn Lake in the Þingvellir National Park in Iceland, Silfra is a rift that is part of the divergent tectonic boundary between the North American and Eurasian plates.

For divers, the glacial water is very cold at 2-3 degrees C, but the payoff is very clear vis - similar to some of Mount Gambier's sinkholes on a good day.

The water in Silfra is pure, filtered and great to drink - Mt Gambier's sinkhole water is generally alkaline, coming through limestone - Silfra's water is filtered through volcanic basalt (and other rock).

Silfra is ice-free all year but the surrounding countryside is covered in snow during the winter. We dived with Dive.is .

The rock colours were amazing

Now she is getting comfortable...

Blairgowrie Pier, Port Phillip Bay

My first foray into underwater still photography was by accident - forgot to switch to video mode. Cannot change this setting in the deep diving casing of the Sony Action Cam. Images taken in January 2015,

Lots of sponges beneath this pier making it one of the best in the Bay (my favourite is Mornington due to its depth, dark places, and large schools of a variety of fish)...
