Two Worlds: Above and Below the Sea

Wühre, Limmatquai

Jennifer Hayes is a contributing photographer, author and speaker for National Geographic Partners. She is a scientist turned storyteller submerging more than 11,000 hours beneath the surface from interior Africa, local ponds to the Pacific to both polar regions.

Jennifer believes it is crucial to give a voice to the living world we share our planet with – it is ours to stand up for or lose. #WeAreInThisTogether

Jennifer’s academic passions lead to graduate degrees in marine ecology and zoology studying shark fisheries for her masters degree and sturgeons for doctoral research. Jennifer has translated her love of science into storytelling, working with scientists around the globe to share the their stories. Jennifer is an award winning photographer, author and contributor to numerous publications and books on marine environments. She is a trustee of the Shark Research Institute, Explorer Club National Fellow and Principal Photographer for Elysium Artists for Antarctic, Arctic Expeditions and Coral Triangle Expeditions. Her work has been featured on NPR, CNN, ABC Good Morning America, ABC World News Tonight, National Geographic TV, Wild and Disney Channel.

Jennifer lives in Clayton, NY with her husband and National Geographic photographer David Doubilet along with their five rescue cats and their dog Arthur. The pair co-own UnderSea Images Inc with the focus on connecting people to the miracle of our planet.

Sustainable Development Goal (SDG) 14: LIFE BELOW WATER

Protecting our oceans

Núria Casacuberta Arola

Professor Núria Casacuberta Arola was born and raised near the sea in Barcelona, Spain. Her passion for the ocean was sparked when she had the opportunity to join a research expedition to the Pacific Ocean, to study the effects of the 2011 Fukushima nuclear disaster. As part of a scientific team sent to monitor the release of radioactive material into the Pacific Ocean, Núria contributed her expertise in the environmental sciences and used it to help investigate impacts on the ocean.

Núria believes in the power of collecting evidence and using it to understand the dynamics of the ocean. What makes her research approach distinct is the use of radioactive atoms released into the ocean from industrial processes. The dose of the radioactive contamination that Núria makes use of is not dangerous for animals or humans, but if released in large-​enough amounts, it can be detected thousands of kilometres away from the source region.

Núria’s work also contributes to understanding the role oceans play in regulating the global climate.

How water travels

Part of the research focuses on detecting how the ocean moves: which pathways water masses follow, and how long they travel through ocean basins. By understanding pathways and circulation times, Núria and her team can estimate the capacity of different water masses to store substances such as greenhouse gases.

The role of oceans in mitigating climate change

Her plan is to embark on a journey to bring tracer oceanography to the forefront of ocean research, and to highlight how much oceans are changing as global climate patterns continue to shift. Núria hopes to see society become more aware of how important oceans are for regulating the Earth’s climate, and how crucial it is that they function well for our future, even for people in landlocked countries like Switzerland.

“Oceans play a vital role in regulating our climate. If we understand the dynamics of the ocean, we will also gain knowledge about its relationship with climate change.”

Soft robots modelled on nature

Robert Katzschmann

A trained mechanical engineer, Professor Robert Katzschmann is fascinated by robotics. Puzzled by why most robots aren’t built to mimic the flexibility we see in nature, he set out to develop soft robots which are made of flexible materials.

Soft robotic fish

Robert began by exploring underwater robotics, guided by the natural softness of many aquatic creatures such as octopuses and fish, and inspired by their capacity to create deformable structures capable of being reshaped again and again.

His team has developed a soft robotic fish that mimics the motion of real fish through a cyclic, undulating movement. This behavior makes robotic fish less intimidating than most underwater vehicles, which rely on systems like propellers or jets that tend to disturb the delicate balance of underwater ecosystems.

Robert is using biomimicry – the practice of learning and adapting patterns from nature – to understand marine life, and build better knowledge of underwater species and their behaviours. He is developing a customisable platform for biologists whose work involves the study and imitation of fish species. He is also working on long-​term environmental monitoring applications, where robots are equipped with eDNA filters to collect data on fish species and their habitats. This data helps to identify and track fish in real time.

Rethinking the robot

Convinced that we should reconsider the design and purpose of robots, Robert envisions a future where they are designed to blend into our natural environment, making them suitable for homes and workplaces. Through the use of sustainable and biodegradable materials, robots can be created with minimal environmental impact.

A gadget like a robotic fish can also attract attention from the broader public. Robert is optimistic that this can spur greater interest in ocean life and marine animals, which in turn can help people to rethink their nutrition and consumption habits to help restore habitats and fish populations.

“Creating a sustainable future requires us to understand the impact of our actions as humans and technologists. By designing systems and technologies that minimise our ecological footprint, we can pave the way for a productive yet environmentally conscious future.”

3D-​printing a new home for reef life


rrreefs is an ETH Spin-​Off run by four women – Ulrike Pfreundt, Marie Griesmar, Hanna Kuhfuss and Josephine Graf.

Dr. Ulrike Pfreundt is an expert in tropical ocean ecosystems, she understands ocean dynamics from the point of its smallest inhabitants. After completing her Masters in fine arts, Marie Griesmar learned digital fabrication processes to further develop artificial reef structures.

When Ulrike and Marie met at the ETH Zurich, they were a perfect match. Both have a deep connection with the ocean. Their passion has been reinforced with scuba diving; a way to connect with the underwater world on another level. They’ve witnessed the beauty of coral reefs, but sadly also their degradation. This loss of biodiversity motivated them to learn about reef ecology and to find solutions to sustain those fragile ecosystems.

Rebuilding reef structures using 3D-​printed clay modules

Over the last 30 years, the world has lost half of its coral reefs, and more than 90 % of all reefs are expected to vanish by 2050.

rrreefs‘ mission is to rebuild degraded coral reefs to bring back abundant marine life, that also protect shorelines and strengthen the resilience of coastal communities. Their reef systems provide a new home for reef organisms and promote the settlement of coral larvae. It is a modular system of 3D-​printed rrreef modules made with natural clay.

rrreefs‘ vision for the future is to revive 1 % of coastal coral reefs by 2033. They believe that companies, institutions, and entities have a responsibility towards our planet, and they have a chance to create a positive ecological impact.

Awareness raising for coral reefs

rrreefs‘ research and fieldwork opens a space of possibilities that should inspire hope while creating impact. Anyone who wants to actively contribute to protecting coral reefs can be proactive, whether it is learning about the local challenges on the next dive vacation, collecting trash from the ocean, or supporting organizations like rrreefs from home. rrreefs can be supported by simply donating or by being part of its community to increase awareness towards the loss of coral reefs.

“We created an opportunity for changemakers and pioneers to create a positive ecological impact.”
