How much life is there in a drop of seawater?
For a better understanding of the impact of human activity on Europe’s seas and coasts.
A habitat rich in biodiversity – Europe’s coasts and oceans are home to a wide variety of plants and animals and are essential for the stability and sustainability of larger ecosystems.
There is a growing awareness of the effects of human activities on natural habitats, pollution, the decline in biodiversity and climate change. To gain a better understanding of humans’ impact on European coasts and oceans, ZEISS accompanied EMBL1 on the unique research expedition TREC (Traversing European Coastlines) across Europe.
An expedition to tackle ecological challenges
Exploring biodiversity, understanding ecosystems and studying the effects of changing environmental conditions on organisms – these are the goals of TREC, a scientific journey initiated by EMBL along the European coast.
Samples were taken from coastal habitats and the diversity of organisms is studied from viruses, bacteria and protists to multicellular groups such as algae and animals.
The vision for TREC is really serving big society environmental problems like climate change, but also biodiversity decline and loss. Chemical pollution is a big pillar of TREC.
From Roscoff to Bilbao
Mobile truck laboratories equipped with state-of-the-art technologies (including ZEISS microscopes) visited over 100 sites in 24 European countries between April 2023 and July 2024. Within this period, researchers collected biological samples and environmental data on 115 land-sea transects. The expedition thus combined ocean research with parallel sampling of soil, sediment, shallow water and selected model organisms in different habitats.
The primary objective of TREC is the systematic and standardized sampling and multimodal acquisition of environmental metadata. The aim of gathering this data was to conduct the first Europe-wide consensus of European coastal ecosystems and to record the impact of humans on the environment and on microscopic and macroscopic organisms.
We need to act immediately and internationally because ecosystems don't stop at national borders. We are facing challenges that are planetary challenges like climate change.
Gaining knowledge and conducting research
Along the TREC route, in cooperation with schools, young people had the opportunity to delve into this topic.
Bringing together people from different countries with expertise in different disciplines facilitated discussions about the challenges of the present and the future. Knowledge and progress were shared with the public through a variety of scientific workshops on a wide range of topics from demonstrating the power of molecular biology in addressing societal challenges through to highlighting the connection and interaction between humans and their planet.2
Inspiring the explorers of tomorrow and generating enthusiasm for science is also the goal of “A Heart for Science”, an international ZEISS initiative that aims to get young people aged 12 to 18 interested in STEM. ZEISS employees have been participating along the route as part of this cooperation to raise awareness of the importance of science for sustainability among the younger generation.
Focus on environmental research
-
Biosciences incorporate all fields of study and research that address the organisms and mechanisms of life. This includes biology, medicine, chemistry, biophysics, nutritional science, agriculture, environmental sciences, biodiversity research and more.
-
Understanding the influence human activity has on ecosystems and the decline in biodiversity is key to comprehending how humans are contributing to climate change. This is the aim of the TREC expedition. A multitude of samples were taken from the air, soil, water and at the intersects along the European coast. Researchers are intending to publish the data worldwide.
-
Expanding our scientific knowledge is not just key to improving the health of the ecosystems, getting the population involved in this research and interpreting the results can also give rise to a change in the way people treat the seas, oceans and coastal regions. Programs such as Nexus Island enable people to interact with researchers and to experience science for themselves. Through “A Heart for Science”, young people get the chance to dive into natural sciences and explore how research can help to solve societal issues.
Sustainability initiatives at ZEISS
ZEISS is committed to contributing to the environment and encouraging sustainable practice in the day-to-day operations. Based on the global sustainability goals adopted by the United Nations, ZEISS has derived three focus topics – value for society, climate action and circular economy – and is initiating concrete measures based on these focus topics worldwide.
