Road Trip: 2. The Selenga Delta

The three days we spent in the Selenga Delta were pretty jam-packed, covering a large distance, sampling all of the sites shown below.

The reality of sampling the Selenga Delta became apparent rather quickly. Our high aspirations to sample some of the more remote, inner locations in the delta were soon trumped given the time limitations we had and the absence of a small boat complete with engine. The currents in even some of the smallest channels was quite fast and with such high grasses and Phragmites bordering all channels, it was quite hard to orientate oneself.

For starters, just trying to locate any lakes from maps or satellite imagery, given the ephemeral nature of a Delta, was hard enough. Not to mention dragging all our coring equipment and boat across head high Phragmites fields!

Nevertheless, we were very pleased with the different sites that we were able to sample and given the different locations we looked at, feel confident we captured a lot of the delta’s main characteristics. Here are some pics of the different sites we visited. As you can see, the vegetation shows some quite dramatic changes:

Needless to say, apart from the hard work…some very fun moments were had. Despite all the mosquitoes that plagued us at night! To find out about more of our adventures, heading upstream of the Selenga River, stay tuned…
