Millions of species live in the sea. Biodiversity contributes to the health of the ocean, regulates the climate, and provides valuable resources. Protecting biodiversity is crucial for the survival of our planet.
The ocean is home to millions of species. This incredible diversity helps maintain the ocean’s health, regulates the climate, and provides valuable resources. Protecting marine biodiversity is essential for the survival of our planet.
All ecosystem services of the ocean are vital for both humanity and nature.
The ocean forms the largest continuous habitat on Earth and is home to millions of different plants, animals, and microorganisms.
Ecosystems can withstand the pressure arising from climate change and human interventions only to a certain extent.
Today, many ecosystems are disturbed or even destroyed, but some can be restored - for the benefit of people and nature.
Seagrass meadows, their ecosystem services, their protection and their restoration are presented clearly and concisely in the information series ‘Discover’ of the GEOMAR Research Centre.
The European oyster plays a vital role in maintaining ecosystem functions in its habitat. Currently considered extinct in the German North Sea, it is being reintroduced through a project at the Alfred Wegener Institute (AWI).

This policy paper (2023) for the UN Decade on Ecosystem Restoration (2021-2030) addresses the restoration of marine and coastal ecosystems, outlines the context, identifies challenges, and provides recommendations for action.
Marine biodiversity is under pressure. The HIFMB Transfer Office for Marine Biodiversity Change provides facts and expertise from science for politics, marine conservation and management.
Dive into one of the most biodiverse marine regions in the world: In this video, the Centre for Tropical Marine Research (ZMT) shows the importance of coral reefs for humans and the effects of climate change on these unique ecosystems.
What is the state of biodiversity in Germany? The BMBF Research Initiative for the Conservation of Biodiversity (FEdA) provides facts, a comprehensive database, and recommendations to counteract biodiversity loss.
This focus area of the Alfred Wegener Institute (AWI) provides up-to-date knowledge on changes in biodiversity, the impacts of climate change, and advisory services at the North Sea Office.
The Wadden Sea is currently changing more rapidly than it has in thousands of years. This focus area of the Alfred Wegener Institute (AWI) vividly illustrates the changes caused by introduced species.
This information video presents the Humboldt Current upwelling area off the Pacific coast of South America, which provides millions of tonnes of fish and seafood every year and is considered a hotspot of marine biodiversity.
The biodiversity and ecosystem functions of the deep sea are far from being fully explored. This contribution to the information series ‘Discover’ by the GEOMAR Research Centre presents fascinating findings about the largest habitat on earth.
Research videos show fascinating habitats and biodiversity in the deep sea, explanatory films and expedition reports complete the ‘MARUM TV’ offering from the Center for Marine Environmental Sciences at the University of Bremen.
Living conditions in the Arctic have changed as rapidly in recent decades as in hardly any other ecosystem on Earth. This thematic focus from the Alfred Wegener Institute (AWI) provides the facts.
Can coral reefs regain their functions after coral bleaching? What factors contribute to the recovery of species-rich ecosystems? This summary of an international study by the Centre for Tropical Marine Research (ZMT) provides answers.
This database contains various threats faced by over 120 species of marine mammals worldwide, including whales, seals, polar bears, sea otters and manatees, provided by the University of Veterinary Medicine Hannover (TiHo).
Why cephalopods are better adapted to climate change than other marine animals, and what the significance of their spread in the North Sea could be for fish stocks and the fishing industry, is explained in this article.
Invasive species pose major challenges to ecosystems worldwide. The Centre for Tropical Marine Research (ZMT) reports on how an app can help with research into invasive lionfish in Brazil.

The health of the seas and oceans is deteriorating. The trend can only be reversed if marine protection and sustainable use are pushed forward consistently.
If nutrients are present in sufficient quantities, marine life follows its usual course. However, when they are excessively introduced large blooms of algae can occur.
Untapped ore deposits lie in the depths of the oceans; plans for extraction are underway, yet the impact on the delicate deep-sea ecosystems remains largely unknown.
Fish and seafood are among the most widely traded foods in the world; but only sustainable management can ensure their preservation and their contribution to tackling the climate and biodiversity crises.
The ocean absorbes a huge amount of heat at its surface, which is stored at increasing depths. This leads to an increase in water temperature, impacting the climate and the marine life.
The absorption of carbon dioxide from the atmosphere leads to fundamental changes in the chemistry of the ocean, impacting biological processes across a variety of life forms.
The ocean's pollution issue is growing exponentially. An increasing production and disposal of plastics contribute to the problem.
Things are getting louder underwater: construction noise, engine noise and explosions can harm marine life and disrupt their communication or even make it impossible.
Every six years, experts assess the environmental state of Germany’s marine areas. The comprehensive 2024 report reveals that the German North Sea and Baltic Sea are in poor condition.
The precautionary principle and the polluter pays principle are important foundations for the regulations on the protection of coasts and oceans.
The world’s seas oceans are losing oxygen – one of the most vital building blocks of life. The main causes: ocean waters are steadily warming, and excessive nutrient input in many coastal areas is driving widespread imbalance.
