When considering underwater photography, we usually think about images of wonderful coral reefs, colourful fish, clear waters and undersea landscapes. In fact, 70 percent of our planet is covered by water on its surface, and, even though 97 percent of this is saltwater, the remaining three percent is freshwater in rivers, streams, lakes, ponds, marshes and groundwater.

Austrian Lakes: Grübl See & Grüner See

We were lucky to be some of the last few divers to enjoy the crystal clear waters of Grüner See before diving was banned in 2017. Photo by Marco Daturi.

Austria offers divine diving at high altitudes in freshwater lakes. Marco Daturi takes us to two beautiful lakes found in the mountains of Styria­­—one that continues to enthrall and one which has recently been closed for conservation and protection.

Pacific Northwest: Sockeye Salmon

We walked nearly a mile along the riverbank before finding a place where we could easily enter with our heavy equipment. The rotting carcasses of dead fish lay along the banks, and the associated stench was overpowering. It was late September 2010, and we had come to photograph an enormous migration of sockeye salmon, the largest run of sockeye in a century.
