Uraren azidotasunari buruzko ikerketa Bizkaiko hiru estuariotan: Urdaibai, Plentzia eta Nerbioi-Ibaizabal
Oceans cover around a 70% of the planet surface and play a key role in the Earth’s major processes. In the last 200 years, CO2 emissions have increased due to human activities. Atmospheric CO2 concentration has increased from the preindustrial level of 280 ppm to around 415 ppm nowadays, and accordi...

Oceans cover around a 70% of the planet surface and play a key role in the Earth’s major processes. In the last 200 years, CO2 emissions have increased due to human activities. Atmospheric CO2 concentration has increased from the preindustrial level of 280 ppm to around 415 ppm nowadays, and according to some studies, it may reach values of 936 ppm by 2100, if emissions continue unabated. The increase of CO2 concentration has two main effects: the rise of the global temperature, known as the intensification of the greenhouse effect; and ocean acidification. Oceans absorb CO2 excess, lowering its concentration in the atmosphere but decreasing the pH of the water. Besides seawater, the necessity of researching other interesting water systems, such as estuaries, has been signaled. The effects of CO2 increase have not been widely studied in these systems, which are considered very important since they are the habitat for a lot of species of animals and plants.
