More than 15 scientists and filmmakers from National Geographic Pristine Seas have embarked on a significant expedition to Tuvalu, where they will study the marine environments with the aim of enhancing ocean conservation efforts. This months-long research initiative will focus on diverse aquatic ecosystems ranging from deep sea to lagoons and coral reefs, many of which remain largely unexplored.
This expedition is being conducted in partnership with the Tuvalu Government, which will receive valuable data to develop ocean management plans and make informed decisions about protecting specific areas of their territorial waters. As Tuvalu is currently drafting its National Ocean Policy, this collaboration comes at a pivotal moment for the nation, which is facing the detrimental effects of climate change, including rising sea levels and coastal erosion that threaten both its marine biodiversity and coastal communities.
Tuvalu, a nation comprising six low-lying atolls and three reef islands, is home to a rich variety of marine life, including species like silky sharks, giant clams, bumphead parrotfish, tuna, and Hawksbill turtles. “The ocean is our livelihood, our home and our connection to our ancestors,” remarked Tuvalu’s Prime Minister Feleti Teo, emphasizing the cultural importance of ocean health to the nation.
The Pristine Seas team will utilize advanced submersible technology, including the Argonauta, to explore the deep ocean, capturing real-time data on marine species and habitats for the first time in many areas of Tuvalu’s waters. They will also employ baited remote underwater video systems and conduct SCUBA surveys to assess and estimate the populations of various marine species, including endangered ones like the humphead wrasse and Herman sea cucumbers.
Currently, Tuvalu has only one marine protected area—the Funafuti Conservation Area—which covers a mere 33 square kilometers. The findings from this expedition are anticipated to help identify new marine protected areas that can enhance ecological resilience against climate challenges. “A healthy coral reef ecosystem can protect families and communities from the destructive effects of sea-level rise, flooding, and coastal erosion,” stated Keiron Fraser, expedition leader for this initiative.
Further, the expedition will include educational outreach, allowing local students and educators to interact with scientists and filmmakers, learning about marine science and potential career pathways in this field.
Pristine Seas’ broader Global Expedition, which started in 2023, aims to support Pacific communities and governments in their conservation efforts over a span of five years, making this expedition in Tuvalu the tenth stop on its mission. Past research has shown that understanding the interconnectedness of marine life across regions is vital for effective ocean protection, a sentiment echoed by Whitney Goodell, who noted how different ocean areas are interlinked.
This expedition not only strives to protect ocean biodiversity and contribute to long-lasting environmental stewardship but also brings hope for sustainable futures for communities that rely on healthy marine ecosystems.
