Temple researchers have made a groundbreaking discovery in Argentina, uncovering a massive cold-water coral reef system that could be one of the largest in the world. This find is a significant contribution to our understanding of deep-sea ecosystems and their importance. Erik Cordes, a professor and chair of the Department of Biology, and Morgan Will, a biology PhD candidate, are leading the charge in this exploration and restoration project. Their work is part of a larger global effort to study and protect these mysterious reefs.
Cordes and Will are collaborating with the University of Buenos Aires and the Argentine Museum of Natural Sciences (CONICET) on a $1.5M research project funded by the G20 Coral Research and Development Accelerator Platform (CORDAP). Their mission is to locate, characterize, and restore cold-water coral reefs off the coast of Argentina. During their recent expedition, they utilized a high-tech remotely operated vehicle (ROV) named SuBastian to explore the ocean floor and uncover the extent of these reefs.
The researchers were amazed by the scale and diversity of the cold-water coral reefs they discovered. Cordes estimates that these reefs cover twice the area of shallow water coral reefs like the Great Barrier Reef. One of the most exciting findings was the presence of Bathelia candida, an uncommon coral species previously known only in the deep seas of South America. The size and extent of the Bathelia coral system in Argentina surprised the team, indicating a potentially significant contribution to global biodiversity.
Cold-water coral reefs are vital ecosystems that support biodiversity and play a crucial role in carbon sequestration and nutrient cycling. They are particularly vulnerable to human activities such as fishing, oil and gas development, and pollution. Cordes emphasizes the importance of creating a baseline for healthy reef conditions to measure the impact of human activities. This baseline will help researchers understand the extent of damage and develop effective restoration strategies.
One of the challenges in reef restoration is the lack of previous experience in deep-sea environments. Cordes and Will are adapting strategies from a project off the coast of Louisiana, where they are restoring reefs damaged by the 2010 Deepwater Horizon oil spill. They are experimenting with building artificial coral skeletons using cement and crushed coral sand to simulate coral habitats and encourage the return of wildlife.
Will's experience on the cruise was particularly memorable, as she had the opportunity to observe structure-forming cold-water corals firsthand. She described the sight of a massive Bathelia mound teeming with life as breathtaking. The project has also fostered international collaboration, with Temple and Lehigh University in the US partnering with the University of Buenos Aires and the Argentine Museum of Natural Sciences. This exchange of knowledge and resources will strengthen the capacity for deep-sea research in Argentina.
Cordes highlights the importance of improving deep-sea research capabilities in Argentina, as the country previously lacked the necessary infrastructure. By sharing their expertise and resources, Temple researchers are contributing to the development of a global network of deep-sea exploration and conservation. The Schmidt Ocean Institute's YouTube channel provides a glimpse into the expedition's findings, showcasing the beauty and importance of these hidden ecosystems.
In conclusion, the discovery and restoration of cold-water coral reefs in Argentina is a significant achievement in marine biology and conservation. Cordes and Will's work not only expands our knowledge of deep-sea ecosystems but also highlights the need for international collaboration and the development of innovative restoration techniques. As we continue to explore and protect these fragile environments, we must also address the human impacts that threaten their existence.
