Perpetual Planet Amazon Expedition

At the river mouth

With support from the Rolex Perpetual Planet Initiative and National Geographic Society, Angelo Bernardino and Margaret Owuor have been uncovering the mysteries of Brazil’s mangroves at the mouth of the Amazon River, one of the least-understood ecosystems on the planet.
Knee-deep in sticky mud, eyes squinting against the driving rain, marine ecologist and National Geographic Explorer Angelo Bernardino works quickly to extract core samples from the soil. He is deep inside a mangrove forest at the mouth of the Amazon River and the tide is coming in fast. In a few hours, this patch of dry land could be under several metres of water.
