This past year proved to be tumultuous for the world’s oceans, marked by ongoing challenges related to overfishing and pollution, as well as the alarming increase in global temperatures that has left many scientists baffled. Johan Rockström, the chief scientist at Conservation International, noted that while strides have been made in addressing environmental issues, the warming of ocean waters continues at a pace that experts struggle to fully understand.
Nonetheless, efforts in marine conservation have seen hopeful developments. Conservationists and local communities have been actively engaged in initiatives aimed at safeguarding marine ecosystems, showcasing a blend of science and advocacy as they tackle pressing issues facing oceanic health.
This year has seen significant advancements in our understanding of ocean biodiversity and conservation efforts. Here are some key highlights from 2024.
A major deep-sea expedition, sponsored by Conservation International, has unveiled the mysteries of an extensive underwater mountain range off the coasts of Chile and Peru. Over the course of a month, scientists investigated the Salas y Gómez and Nazca ridges, utilizing underwater robotics to potentially identify over 100 previously unknown species. Erin Easton, the lead scientist on the expedition, remarked on the astonishing discoveries made within mere meters of exploration.
Globally, whale shark populations, the largest fish species, have been declining sharply due to overfishing, and despite international conservation efforts, their numbers continue to drop. Mark Erdmann, a marine biologist with Conservation International, pointed to a significant concern: collisions with cargo ships. A recent study indicates that climate change may exacerbate this issue by pushing whale sharks away from the equator and into heavily trafficked shipping lanes. An effective mitigation measure that has shown promise is reducing ship speeds, which could help shield these magnificent creatures from further harm.
Tragically, nearly one-third of fishing lines used in the ocean are either lost or abandoned, contributing to a deadly phenomenon known as “ghost fishing,” which threatens countless marine mammals. Edgardo Ochoa, a diving safety officer with Conservation International, has made it his mission to address this issue by retrieving thousands of pounds of lost gear. Recognizing the scale of the challenge, Ochoa has mobilized a team of nearly 100 divers to join in this vital cleanup effort.
In a different realm of conservation, surf breaks around the globe are emerging as crucial players in the battle against climate change. Surrounded by diverse ecosystems—including mangroves, seagrasses, and coral reefs—these areas act as essential carbon sinks. Scott Atkinson from Conservation International is actively engaging the surfing community to advocate for the protection of these ecosystems, highlighting their beauty and significance to both the environment and local economies.
Raja Ampat, an archipelago in West Papua, Indonesia, has been identified as a rare sanctuary for manta rays, with populations thriving thanks to robust marine protections. However, recent studies conducted in partnership with local organizations, such as Konservasi Indonesia, have raised red flags regarding the potential impact of nickel mining on these delicate habitats. With rising demand for the metal, conservationists are increasingly concerned about the ecological ramifications just outside of the archipelago’s protected marine zones.
To combat misconceptions around sharks that often lead to environmental harm, a South African company called SharkSafe Barriers is innovating in the field of marine safety. Supported by Conservation International’s investment fund, CI Ventures, the company has developed magnetic barriers designed to deter sharks while protecting other marine species such as turtles and dolphins, thus addressing safety concerns without exacerbating ecological threats.
As these various initiatives unfold, they underscore a broader movement within marine conservation that balances ecological integrity with human interests. The collective efforts of scientists, conservationists, and local communities remain essential in the ongoing quest to protect our oceans amid mounting pressures.
