a relative 150 scientists from NASA Studying the depths of the oceans to find out future oxygen levels including A Spanish: Carmen
150 scientists, 3 ships and 70 high-generation instruments are assigned to the expedition to explore the places where the sun’s rays cannot reach. Among the Spanish researchers, Elena Ceballos.
The researcher’s work from the University of Seville, on the NASA-funded Ocean Twilight Zone mission developed in the North Atlantic, has involved studying the auroral zone, which is key to oxygen production on Earth. “The device I used is an autonomous robot that we can send to a depth of 2,000 metres,” he explains.
The largest lung on the planet
The marine strip inaccessible to light accounts for nearly 60% of the planet’s surface. the The largest lung on the planet Because of its great extension and species diversity. This is why knowing future oxygen levels is so important to predict, among other things, the extent of long-term organic carbon storage or the effects of Climate change.
The oceans absorb 30% of carbon dioxide (CO2). from the atmosphere. First, carbon dioxide dissolves at the surface of the water and then ocean circulation transports it to the sea floor, where it accumulates over time.
Impact on marine animals
However, experts warn that the first results of excess carbon dioxide in the oceans have already been observed. The most obvious are: sea level rise, acidification of the water and its effects on marine animals.
