Chemical characterization of Punta de Fuencaliente CO2 seeps system (La Palma Island, NE Atlantic Ocean): a new natural laboratory for ocean acidification studies
We present a new natural carbon dioxide (CO2) system located off the southern coast of La Palma Island (Canary Islands, Spain). Like others CO2 seeps, these seeps can be used as an analogue to study the effects of ocean acidification (OA) on the marine realm. With this aim, we present an accurate ch...
