A new study has shown that the Atlantic Meridional Circulation has been weakening for nearly two decades, which could significantly impact the climate, precipitation, and sea levels in adjacent regions. Long-term observations are helping scientists better predict potential climate changes in the future.
The Arctic permafrost holds vast reserves of organic carbon, which can be released into the ocean as it thaws and influence the climate. Recent studies show that only a portion of this carbon turns into greenhouse gases, while most of it remains on the ocean floor. This finding is crucial for predicting future climate changes.
Scientists have discovered three previously unknown genotypes of Helicobacter bacteria in pygmy sperm whales, which may be linked to diseases of their gastrointestinal tract. This finding raises important questions about the impact of bacterial infections on the health of marine mammals and the overall state of ocean ecosystems.
A mysterious object discovered at a depth of 3,250 meters in the Gulf of Alaska turned out to be the remains of the deep-sea anemone Relicanthus daphneae. This finding highlights that the depths of the ocean are still full of secrets.
Studies show that Nitrosopumilus maritimus microbes are able to adapt to ocean warming and iron deficiency, while maintaining their crucial role in the nitrogen cycle. This adaptability may influence the biochemistry and resilience of marine ecosystems in the face of climate change.
A new study has shown that even during Earth's harshest ice ages, the climate remained variable, resembling modern climate cycles. This discovery changes our understanding of the stability of ancient climate systems.
Coral reefs provide immense benefits to humanity, but due to ocean warming, more than half of the world's reefs have suffered mass bleaching and die-offs. A new study offers the first precise assessment of the scale of this threat and highlights the importance of global monitoring to ensure their preservation.
Calcifying plankton play a crucial role in regulating the climate, yet their impact is often underestimated in current climate models. A new study urges that the diversity and vulnerability of these organisms should be taken into account to improve the accuracy of climate change predictions.
The study found that the endangered Kemp's ridley sea turtles are particularly sensitive to low-frequency noise, which overlaps with the range of human-made sounds in the ocean, making them vulnerable to acoustic disturbances.
Scientists have developed the first system for detecting and comparing short-term but intense periods of underwater darkness—so-called "marine dark waves"—which can seriously disrupt marine ecosystems. This new method will help track such events worldwide and assess their impact on algae, seagrasses, and corals.
In 2025, the world’s oceans reached record levels of heat accumulation, intensifying extreme weather events and impacting the global climate system. The study highlights the urgent need to reduce emissions and take collective action to preserve a stable and favorable climate.
A new study has shown that plastic and oil in the ocean can combine to form a stable hybrid pollutant capable of traveling vast distances. The impact of this "oil-plastic" on ecosystems is still not well understood.
Scientists are concerned about the disappearance of the "zombie" worm Osedax, which plays a crucial role in decomposing whale bones in the ocean. Its absence could signal serious ecological problems and a decline in biodiversity.
A new study has shown that persistent cooling south of Greenland is linked to a weakening of the Atlantic Meridional Overturning Circulation, which could significantly impact the climate of Europe and North America.
Studies have shown that oceanic manta rays dive into deep waters not for hunting, but to recalibrate their “maps” of the ocean and navigate in open waters. These findings help us understand how migratory species cross vast distances and highlight the importance of preserving little-studied deep-sea ecosystems.
