'To allow scientists to gather data from remote places, as we can’t be there just taking samples every day in these places, we deploy scientific instrumentation, in this case, oceanographic sensors that measure different water parameters. We can trust its data. This sensor is actually a small laboratory that runs a specific protocol to take little water samples. The sensor measures the reaction of the PH and calculates the partial pressure of CO2 in the water. CO2 is one of the anthropogenic impacts of industrialization. It’s a gas whose concentration has been changing significantly in the atmosphere, especially in the last 100 years. When this gas mixes with the ocean, it acidifies the wate...
