WWII WRECKS – A TOXIC LEGACY?
Maritime archeologist Matt Carter discusses what brought him to Chuuk Lagoon and his quest to call attention to the oil leaking from WWII shipwrecks, the focus of the Major Projects Foundation, where he serves as Research Director. The foundation was created with the goal of working with Pacific nations to protect their marine ecosystems from potential oil spills from WWII shipwrecks, and is currently working to determine determining how much oil the ships lost in the Asia-Pacific region still hold. Previously a team of international experts calculated the amount of oil to be anywhere between 150 million and 1.2 billion gallons.

Maritime archeologist Matt Carter discusses what brought him to Chuuk Lagoon and his quest to call attention to the oil leaking from WWII shipwrecks, the focus of the Major Projects Foundation (MPF), where he serves as Research Director. The foundation was created with the goal of working with Pacific nations to protect their marine ecosystems from oil spills from WWII shipwrecks.
What many people know is that between 1939 and 1945, the Japanese military and the Allied powers fought an increasingly bloody war through South-East Asia and out across the Pacific Ocean. What fewer people know is that this maritime war saw the loss of some 3800 ships which sank, taking with them their crew, cargoes, and in some cases huge volumes of toxic heavy fuel oil.
One of the questions that Carter is asked frequently is how much oil could these ships possibly still be holding today? In 2005, a team of international experts came together to answer just that question. Searching through archives for information on these potentially polluting shipwrecks (PPW), they calculated that combined, all of the ships lost in the Asia-Pacific Region could possibly still hold anywhere between 150 million and 1.2 billion gallons of oil!
MPF was established in 2018. After signing a memorandum of understanding with the Secretariat of the Pacific Regional Environment Programme (SPREP), the foundation began reviewing and prioritizing the 3800 WWII shipwrecks sunk in the Asia-Pacific Region, resulting in a priority list of 55 PPW deemed to be the highest environmental risk. Seventeen of these wrecks are located in the world-famous diving Mecca of Chuuk Lagoon in the Federated States of Micronesia.
One of the key tools that the foundation used for investigating the condition of the PPW in Chuuk was photogrammetry, a process where a wreck is scanned by divers taking thousands of overlapping photos which are then run through a 3D software program. The main focus of this photogrammetry work was the wreck of the Rio de Janiero Maru, as oil leaks from the wreck were thought to have impacted nearby mangroves in 2008. Over multiple dives, the foundation surveyed and scanned the shipwreck taking 7350 photos and three hours of video. This was the first time that any of the wrecks in Chuuk Lagoon had been recorded in this way resulting in the 3D model shown below.
From this survey, Carter was able to create a baseline condition assessment of the Rio de Janeiro Maru including a hull integrity assessment that has allowed for a more accurate estimation of the amount of oil that may remain inside the wreck. This information was subsequently incorporated into a ‘Likelihood of Oil Release’ assessment providing MPF and the Chuukese authorities with a greater understanding of the potential threat that this wreck poses.
The survey of the Rio de Janeiro Maru has shown what can be achieved through the combination of marine archaeology, technical diving, and photogrammetry. However, this is only the first of the 55 potentially polluting wrecks throughout the Pacific that MPF and its partners urgently need to assess in order to mitigate the impact that these ticking ecological time bombs will have on the people and marine ecosystems of the region.

“Museums are places of conservation, education, and about protecting something sacred. We need to assign those same values to our oceans.”
“As soon as we sink them, they belong to the sea.“
“The Rising Tide was located within sight of the Houses of Parliament. The politician on a petroleum horse was an obvious metaphor for how fossil fuel companies are embedded into our politician system. I think we really have to start holding people accountable for what they are doing. And that needs to be documented in stone rather than in a few words in a newspaper column that disappears. There are a lot of people whose actions need to be immortalised.”
“It is named a museum for a simple reason. Every day we dredge, pollute and overfish our oceans, while museums are places of preservation, of conservation, and of education. They are places where we keep objects that have great value to us. Our oceans are sacred.”

Jason deCaires Taylor MRSS is an award winning sculptor, environmentalist and professional underwater photographer. For the past 16 years, Taylor has been creating underwater museums and sculpture parks beneath the waves, submerging over 1,100 living artworks throughout the world’s oceans and seas. Themes explored by these artistic installations include, among others, the climate emergency, environmental activism, and the regenerative attributes of nature. The sculptures create a habitat for marine life whilst illustrating humanity’s fragility and its relationship with the marine world. Taylor’s subjects mainly feature members of the local community, focussing on their connections with their own coastal environments.
