Description of facility

Pressurized Titanium tank (Karl Erik TiTank) was developed specially to study the impact of CO2 leakage on the marine ecosystem, is a unique experimental vessel. KE-TiTank offers us a continuous monitoring of CO2 l impact on marine ecosystem under fully controlled seawater flow rate, various CO2 fluxes, and various pressures (1 - 30 atm) conditions. Various experiments using TiTank under different conditions that mimic the natural variations, can provide us knowledge needed to improve existing monitoring techniques or to develop innovative monitoring techniques. Various CO2 gradient experiments can provide us novel knowledge needed for early detection of harmful effects of CO2 on marine ecosystem, for management and control of CO2 storage sites, and to develop preventive means for marine resources.

Experiments with TiTank will be highly complementary for Ocean Acidification experiments including mesocosm and benthic chamber experiments.

Both primary effects (effects of high CO2 and low pH) and secondary effects of CO2 (such as changing the mobility and patterns of the distribution of the trace elements / metals in sediment, sediment –water interface and water column) can be studied. See a detailed decribtion (pdf).
