RV Maria S. Merian Explores the Ocean Planet

The RV Maria S. Merian is a state-of-the-art research vessel that has been exploring the ocean's depths since 2019. It's a floating laboratory that's equipped with cutting-edge technology to study the ocean's ecosystem.

The ship is named after the German naturalist Maria Sibylla Merian, who was known for her detailed illustrations of insects and plants. This is a fitting tribute, given the vessel's focus on understanding the complex relationships between marine life and their environments.

The Maria S. Merian has a crew of experienced scientists and researchers who are passionate about uncovering the secrets of the ocean. They're on a mission to gather data and samples that will help us better understand the impact of human activities on the ocean's health.

The RV Maria S. Merian is Germany's second most modern research vessel, named after the naturalist and illustrator Maria Sybilla Merian.

It's a behemoth of a ship, measuring 94.80 meters in length and 19.20 meters in width, with a maximum draft of 6.50 meters.

The Merian is crewed by 24 crew members and can accommodate 22 scientists, making it an ideal platform for multidisciplinary research.

It's equipped with two azimuth thrusters, a lateral pump-jet, and satellite navigation, allowing it to automatically maintain an exact position.

The ship is capable of operating in near-polar regions and can handle drift ice up to a thickness of 80 cm.

Here are some key statistics about the RV Maria S. Merian:

The Merian is also equipped with several laboratories and can accommodate 150 tonnes of additional scientific equipment in accessible containers.

This flexibility makes it an ideal platform for a range of research assignments, from Arctic research to seabed research to a depth of 10 km.

The RV Maria S. Merian is a research vessel that has been on several ocean expeditions. It's equipped with state-of-the-art equipment, including a remotely operated vehicle (ROV) and a autonomous underwater vehicle (AUV).

The ROV is used to explore the seafloor and collect samples, while the AUV is used to map the ocean floor and track changes in the ocean's ecosystem. The vessel's crew is made up of experienced scientists and engineers who work together to achieve the mission's goals.

During one expedition, the RV Maria S. Merian traveled to the Gulf of Mexico to study the impact of oil spills on marine life. The team collected water and sediment samples, which were later analyzed to understand the effects of the spill on the local ecosystem.

The Ocean Planet Expedition is a journey like no other. It's a chance to explore the vast and mysterious ocean that covers over 70% of our planet.

The longest recorded ocean journey was made by the British explorer Captain James Cook, who traveled over 150,000 miles in just 3 years. He discovered new lands and mapped the ocean floor, paving the way for future explorers.

The ocean is home to the largest living structure on Earth, the Great Barrier Reef, which stretches over 1,400 miles off the coast of Australia. It's a coral reef system that's teeming with life.

The deepest part of the ocean is the Mariana Trench, which reaches a staggering depth of over 36,000 feet. That's deeper than Mount Everest, the highest mountain on Earth, is tall.

The ocean plays a crucial role in regulating the Earth's climate, producing half of the oxygen we breathe, and providing a source of food for billions of people. It's a vital component of our planet's ecosystem.

The main goal of our ocean expedition is to collect data on marine life and ecosystems. We want to understand how these delicate systems are affected by climate change.

We'll be studying the distribution and abundance of marine species, including coral, fish, and invertebrates. This will help us identify areas of high conservation value.

The expedition team will also be conducting surveys to assess the health of coral reefs, which are crucial for maintaining marine biodiversity. We'll be looking at factors like coral cover, fish density, and water quality.

Our research will focus on the impacts of ocean acidification and warming on marine life. This is a pressing issue, as these changes can have devastating effects on entire ecosystems.

We'll be using a range of techniques, including remote-operated vehicles (ROVs) and autonomous underwater vehicles (AUVs), to collect data and observe marine life in its natural habitat. These technologies will allow us to explore areas that would be difficult or impossible to reach otherwise.

By studying the ocean's ecosystems, we hope to gain a better understanding of the complex relationships between species and their environments. This knowledge will inform conservation efforts and help us develop strategies for protecting marine biodiversity.

The RV Maria S. Merian is set to embark on a research cruise as part of the EU project ECOTIP. This expedition will take over three weeks, starting in Reykjavik on August 6, 2022, and ending on August 29, 2022.

The research cruise will cover a vast range of scientific disciplines, including marine geochemistry, microplastics, and microbial community dynamics. Over 20 scientists from various universities and research institutions will be on board.

Prof. Dr. Helmuth Thomas, director of the Institute for Carbon Cycles at the Helmholtz-Zentrum Hereon, will lead the expedition. The team's goal is to understand and predict changes in Arctic marine biodiversity and its impacts on fisheries production and carbon sequestration.

The research cruise will sample both the deep sea and the fjords of Kangerlussuaq, Bessel Fjord, and Dove Bay. This will involve experiments such as trace metal and isotope sampling and zoobenthos and plankton studies.
