Cruise: Visualizing the Deep off Uruguay
The Rio de la Plata drains into the Atlantic Ocean, delivering sediment-rich contents from the Paraná and Uruguay Rivers, each fed by myriad streams and tributaries. The mixing of fresh water with the nutrient-rich seawater upwelled along the continental shelf fosters remarkable biodiversity. Vulnerable Marine Ecosystems, or VMEs, are critical yet fragile habitats that support a diverse array of species, and human activities pose a significant threat to these ecosystems. Currently, there is only one reported VME in Uruguay. It is home to cold-water coral reefs formed by Desmophyllum pertusum, a slow-growing coral that grows throughout the Atlantic Ocean; experts suspect this ecologically important animal is threatened and in decline. Scientists believe there are more vulnerable ecosystems, but have not had access to the technology needed to describe deep-water areas in Uruguayan waters.
