But what sets them apart, and what can be done to limit their impact on the ecosystem? Leopoldo Moro, a biodiversity specialist for the Canary Islands Government and a supporter of RedPROMAR explains that the project was launched in 2015, but the idea emerged four years earlier. “Behind the RedPROMAR app is a huge team of validators and loads of active participants. We’re the ones steering the ship, but the strength of the vessel relies on all of our collective effort. Rogelio Herrera was the driving force behind many initiatives, one of which was that first platform for detecting and reporting jellyfish.”

Seawater does not cool down in winter, and there is a greater influx of tropical species

They are monitoring one indicator: the rise in surface water temperatures in the Canary Islands and Macaronesia. Leopoldo Moro refers to AMOC, the Atlantic Ocean circulation system, and the impact of climate change on its functioning. The water here doesn’t get very cold in winter and migrating tropical species are establishing themselves at an astonishing rate.

He claims that, thanks to the big data they have obtained, they can draw conclusions that scientists were previously unable to reach when they had limited data.
