Film Featuring DCO Scientists at Lake Dziani Dzaha Part of EGU 2016 GeoCinema

Dziani Dzaha presents an unusual combination of characteristics making it a likely analog for some hydrocarbon-bearing lacustrine rocks of economic importance and possibly certain Precambrian environments, including expanding rift valleys and basins.

A DCO sponsored film produced by Sur une île was selected for screening at the 2016 EGU General Assembly in Vienna, Austria. Dziani Dzaha presents an unusual combination of characteristics making it a likely analog for some hydrocarbon-bearing lacustrine rocks of economic importance and possibly certain Precambrian environments, including expanding rift valleys and basins. A dense population of prokaryotes and cyanobacteria dominates the Dziani Dzaha ecosystem—giving it a permanently green color. Its waters are saline (twice the ocean salinity), alkaline (pH = 9), extremely rich in dissolved inorganic carbon (100 times the amount in seawater), and anoxic below one-meter depth. It also precipitates microbialites, which are organo-sedimentary deposits that accrete as a result of a lake-bottom microbial community, forming the locus for mineral precipitation.

View the documentary at EGU 2016 in room 0.90 on Tuesday, 19 April, 14:00 and Thursday, 21 April 2016, 16:30. Full GeoCinema schedule.
