An EPFL scientist has made a major breakthrough in the understanding of coral bleaching – a process that causes corals to lose their color and eventually leads to their death. The process is triggered by warmer ocean temperatures, and, according to the study, it begins much earlier than previous ...
Just as forests are called as the ‘lungs of the earth’, wetlands are the ‘kidneys’ that regulate water and filter waste from the landscape. The kidney comparison aside, wetlands are the primary sources of freshwater, buffers of floods and droughts, recycler of nutrients and chemicals, and inextr ...
A quarter of the carbon emissions that are warming the Earth dissolve into oceans, making them more acidic. Carbon emissions and warming are also causing ocean heat waves, which in turn is bleaching the world's coral reefs.
How the larvae of colorful clownfish that live among coral reefs in the Philippines are dispersed varies widely, depending on the year and seasons—a Rutgers-led finding that could help scientists improve conservation of species.
A more acidic ocean could give some species a glow-up.

Upwelling regions account for just 1% of the world’s oceans, yet they are responsible for producing roughly half of the global fishing industry’s annual harvest—worth an estimated $362 billion as of 2016. These nutrient-dense, cool-water regions play a vital role in global ecosystems, supporting ...
The coral reefs at the Red Sea reserves are in grave danger as a result of rising environmental violations including illegal fishing by trawlers, whose nets threaten Egypt’s national wealth of coral reefs and wildlife and have harmed sea turtle and dolphin populations.
“A jewel of biodiversity”. That’s how scientists have described a newly discovered reef complex off the coast of east Africa, where corals appear to be thriving despite the climate crisis.
Researchers at UC Santa Barbara have investigated the dynamics of ecosystems in parts of the ocean that have no dissolved oxygen to sustain animals or plants, which are known as ocean anoxic zones. In these areas, only microbes that are adapted to the environment can survive.
Under the sea ice, the Arctic Ocean is one of the quietest places on Earth. But it can be very noisy when the ice is forming and breaking up or during storms and when glaciers are calving.
Scientists have discovered a climate crisis refuge for coral reefs off the coast of Kenya and Tanzania, where species are thriving despite warming events that have killed their neighbours.
Fishermen, swimmers and seafood enthusiasts may already know the dangers of "red tides," but a recent study in Frontiers in Climate shows that climate change is increasing the frequency of one type of highly toxic algal bloom off the US west coast.
The Nature Conservancy has completed a significant new project: a region-wide publication of maps of all shallow water coral reefs in the Caribbean. Now, the Caribbean has a clear picture of the habitats found beneath its waves.
Coral reefs could bounce back from bleaching caused by soaring temperatures new research suggests, but only in the right conditions. Coral reefs have provided researchers with some hope that at least one element of nature could ‘bounce back’ from soaring temperatures and a global heatwave induce ...
In 2018, a map named after an oceanographer went viral. The so-called Spilhaus projection, in which Earth is viewed from above the South Pole, was designed to show the connected nature of the ocean basins.
Private mining firms and arms companies are exerting a hidden and unhealthy influence on the fate of the deep-sea bed, according to a new report highlighting the threats facing the world’s biggest intact ecosystem.
The barrier reefs are dying, and climate change is putting the ocean and subsequently, the best surf spots, in jeopardy. Australia’s Great Barrier Reef is the world’s most extensive ecosystem, but is one of the World Heritage Sites that is under threat, and has “lost more than half its coral in ...
Stabilising reef surfaces, remediating reefs after a ship grounding, and other science-based actions that help corals grow are among the suite of innovative actions that can improve the Great Barrier Reef’s health and resilience.
Huon Aquaculture has been savaged after another mass salmon outbreak in Tasmania that could threaten native marine life, with conservationists labelling escape management practices in the state “a circus”.
The Prince Albert II Foundation, the Oceanographic Institute, and biodiversity specialist Biotope have joined efforts to study the seahorse population off the Monaco coastline.
The Covid-19 pandemic brought into sharp focus the relationship people around the world have with the ocean. As lockdowns eased, people flocked to the seashore and the beaches as the oceans’ appeal to the inner stirrings of both body and soul became more pronounced.
