“🗺 Did you know that in 2017, only 6% of the world’s seafloor had been mapped to modern standards? Considering the ocean spans some 70% of the Earth’s surface, that’s a significant gap!
But over the past five years since Seabed 2030 launched, we’ve been able to map almost 25% of the ocean floor.
By discovering more about the seabed, we gain a greater understanding of our environment and can ensure its protection. After all, we can’t protect what we don’t know…”

RT by @foiresearch: It takes two to TANGO!

What do we know about #underwaternoise?

Partners from 🇩🇰 and 🇸🇪 set out to find out through the #EMFF-funded TANGO project.

The project focuses on the impact re-routing shipping lanes has on the #marineenvironment.

The Times reported in 2020 that dichlorodiphenyltrichloroethane, banned in 1972, is still haunting the #MarineEnvironment today. Significant amounts of #DDT-related compounds continue to accumulate in #California condors and local dolphin populations, and a recent study linked the presence of this once-popular #pesticide to an aggressive #cancer in sea lions.
