Remembering Kristina Gjerde: A Pioneer in High Seas Conservation

Kristina Gjerde, a prominent marine conservationist, passed away on December 26, 2025, from pancreatic cancer, just days before the United Nations treaty she helped negotiate to protect high seas biodiversity came into effect. Her death marks a significant loss for the environmental community, particularly in the realm of ocean conservation.

The High Seas Treaty, formally known as the Biodiversity Beyond National Jurisdiction Agreement, was adopted by the United Nations in 2023 after years of negotiations. This landmark agreement aims to establish marine sanctuaries in the high seas, which constitute approximately two-thirds of the world's oceans and are beyond national jurisdiction. The treaty's goal is to conserve 30 percent of the ocean by 2030, addressing the urgent need for biodiversity protection in these vast waters.

Kristina Gjerde, who was 68 at the time of her death, transitioned from a commercial maritime lawyer to a dedicated conservationist following a transformative snorkeling trip in the South Pacific. Her commitment to ocean science and advocacy positioned her as one of the earliest and most effective voices for high seas protection. Gjerde's contributions were instrumental in the treaty's development, and her passing comes at a pivotal moment as the treaty is set to take effect.

Following Gjerde's death, her husband, Adam de Sola Pool, confirmed the news and highlighted her profound impact on marine conservation. The United Nations and various environmental organizations have expressed their condolences, recognizing her as a trailblazer in the fight for ocean protection. The treaty's implementation is seen as a testament to her legacy and dedication to preserving marine biodiversity.

While the High Seas Treaty represents a significant step forward, it faces challenges in implementation. Critics have raised concerns about the enforcement of restrictions and the potential for continued overfishing and pollution in these areas. The effectiveness of the treaty will depend on international cooperation and commitment from the 60 countries that have ratified it, including Morocco, which was the last to do so before the treaty's activation.

As the High Seas Treaty comes into effect, the global community will need to focus on establishing the necessary frameworks for marine sanctuaries and ensuring compliance with conservation goals. Gjerde's legacy will likely continue to inspire future efforts in marine conservation, emphasizing the importance of protecting the world's oceans for future generations.
