THE MARS PROJECT LAUNCHES NEW WEBSITE

Since the spectacular discovery in 2011, a group of dedicated scientist and advanced divers has been engaged in documenting the impressive wreck site in order to unlock the many mysteries surrounding Mars and its violent destiny.

It was the largest and fiercest warship in the world, named Mars after the Roman
god of war. It went up in a ball of flames during a brutal naval battle in 1564,
consigning more than 800 Swedish and German sailors and a fortune in gold and
silver coins to the bottom of the Baltic Sea.

Since the spectacular discovery in 2011, a group of dedicated scientist and advanced divers has been engaged in documenting the impressive wreck site in order to unlock the many mysteries surrounding Mars and its violent destiny. The new website will provide lots of information to the public about the historic importance of the wreck and the exciting process to uncover its truths.

During the last ten years, many groundbreaking digital documentation techniques have been developed, but in an effort to further enhance the possibilities, The Mars Project now seeks corporate sponsorship and private donations to secure the success of the field studies and to optimize the amount and the quality of data gathered every year.

Anybody interested in enhancing the field of maritime archeology by developing methods, techniques, and technology suitable for the underwater world should is welcome to get involved. Any contribution –large or small – will secure the ongoing scientific documentation of the Mars wreck site, and generally advance the field of maritime archeology.

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.
