In the introduction to his new book, conservation biologist David Shiffman quotes Senegalese forestry engineer and conservationist Baba Dioum: “In the end we will conserve only what we love; we will love only what we understand; and we will understand only what we are taught,” Dioum says.
A healthy ocean is critical to all life on Earth, and the UN Ocean Conference is a step in this direction. However, the ocean’s health is declining – from overfishing to acidification.
Beijing could be the key to unlocking a positive outcome at the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), writes American marine biologist Sylvia Earle.
Manta rays and whitetip reef sharks glide past socially distanced visitors at Rio de Janeiro’s hangar-sized AquaRio aquarium. In a laboratory upstairs, above the main gallery, a new experiment is underway, one that marine scientists hope will enhance the survival prospects of the world’s coral r ...
A study published in January in the journal Science found that the oceans are heating up faster than predicted, resulting in rising sea levels, acidification and deoxygenation that are destroying coral reefs and have the potential to bring forth more extreme weather events.
Draped in a colourful saree and shirt, Lakshmi Murgesan dives into the azure waters off India's southern coast to collect seaweed, which is being hailed by scientists as a miracle crop that absorbs more carbon dioxide than trees.
The greatest single climate-induced threat facing the world’s 44 small island developing states (SIDS) is rising sea waters which could obliterate some of the low-lying states, including Maldives, Marshall Islands, Kiribati, Nauru, Solomon Islands, Tuvalu, Palau and Micronesia.
Oxygen levels in the world’s temperate freshwater lakes are declining rapidly — faster than in the oceans — a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality.
Scientists have discovered the world’s largest known subterranean fish in a cave in northeastern India. The “troglomorphic fish” was discovered last year, according to recently released research. “The largest individual seen in the cave was in excess of 400 mm [15.8 inches] in standard length ma ...
Polychaetes are segmented worms that live in nearly all marine habitats, from the shallow seashore or estuaries to the deep sea. They are very abundant, often making up as much as 70% of the animals found in an area. Not only are there many of them, but they are very important in contributing to ...
The International Seabed Authority must commit the mining industry to a sustainable future.
Every Saturday, a group of Cook Island Māori youth slide into scuba gear, grab sticks from the ironwood trees (Casuarina equisetifolia) growing along Rarotonga’s beachfront, and head to the reef surrounding the island. Their mission; to dive for invasive taramea (crown-of-thorns starfish, Acanth ...
A glance at the map of India is enough to understand how vast and wide-ranging the country’s biophysical environment is — from alpine meadows on the Himalayan slopes to coral reefs along the ocean floors.
Overfishing and smuggling of this crucial animal are affecting biodiversity and the livelihood of local fishers in Sri Lanka.It’s after sunset in Jaffna when Anthony Vigrado dives into the waters of Palk Bay, scanning the seafloor to collect what seems to be prized treasure. What he comes back w ...
An investigation is under way into why thousands of dead crabs and lobsters are washing up on the Tees estuary and neighbouring north-east beaches in recent weeks.
Only a handful of people have spotted the dazzling blanket octopus in the wild, making it one of the rarest sights in the marine world.
A hidden forest of algae sponges and hydroids photographed at low tide; a stunning night image of green button polyps under ultraviolet light; and a beautiful shot of a honeycomb moray eel stuck on a ledge on a rocky shore.
The deep blue covers 70 per cent of the earth and has been a source of intrigue for centuries, swallowing ships and submarines and setting the stage for tales of mythical sea monsters or hidden cities.
Seaweed could help feed the world and reduce the impact of the climate emergency, a UN adviser on food has suggested.
As human industry belches out more carbon dioxide, the chemistry of our oceans is changing. The resulting acidification is endangering coral reefs and the myriad creatures that depend on them. Science writer and one-time ocean researcher Juli Berwald wondered how ocean acidification affects jell ...
When conservation ecologist Rob Harcourt went surfing off the coast of Sydney, Australia, he immediately knew the water was warmer than usual.
In the 1980s, farmers in Bangladesh went from paddies to ponds, letting salt water flood their land. Now millions are left counting the cost
IT'S EARLY August and the research vessel Barba sails at 80 degrees north along the coastline of Svalbard. The endless Arctic sun lies low on the horizon, the ocean is calm, and the temperate a mild 5 degrees.
At the beginning of the dive, you’re in the ocean’s epipelagic, or sunlight zone: the shallow waters where light still penetrates and photosynthetic organisms live. But as you dive deeper and deeper, the sunlight above you fades. The ocean around you gets darker and darker, colder and colder.
