“Nalareksa 0.3: Acidic-tive” installation was part of M.A.R.I.N. Ecolocated: Littoral Lives exhibition for ISEA2009. The instruments for the first time was used to analyze salt water sample taken from Belfast harbor where M.A.R.I.N catamaran was docked during its’ participation in ISEA2009. For the installation several sensors were developed on the instruments to create sounds effects from the main sound generator which is the physical impact of air and water.

As already known, people became realizes of climate changes as the result of the significant increase in anthropogenic greenhouse gases (gas emission caused by fossil fuels usage for transportation) and deforestation in concentrations via enhanced greenhouse effects. CO2/CO in large concentrations are created reducing benefit elements such as O2/O3 concentration for humans. Continue reading →
