5,000-year-old underwater peat reefs off Mozambique teem with marine life
Scientists have discovered 5,000-year-old submerged peat forests off the coast of Mozambique that now function as thriving marine ecosystems. These ancient terrestrial remains provide essential structure for seagrasses, sponges, and fish, effectively acting as a nursery for marine life.
Why it matters
This discovery offers new insights into how rising sea levels from the last Ice Age transformed terrestrial landscapes into unique, carbon-rich marine habitats.
Sometimes, drowning can give someone (or something) a new lease on life. This is a 5000 year old story of a drowned forest off Mozambique, which have now become living reefs.Off the coast of Mozambique, beneath the shallow waters near Bazaruto, scientists have found the remains of forests that died thousands of years ago, but are now supporting life in the sea. This new study published in Scientific Reports describes the ancient terrestrial forests ‘reborn’ as modern marine ecosystems under shifting sea levels.Forests that became seabedThe story begins with sea-level change. After the last Ice Age, melting ice raised global sea levels, gradually flooding low-lying coastal land. In the Bazaruto region, swampy forests and peaty ground were submerged.
