In 2016, ornithologist Steven Emslie was studying penguin colonies along the shores of Antarctica’s Ross Sea, when he heard about pebble mounds associated with guano deposits on Cape Irizar, a rocky outcrop surrounded by water and ice. Guano forms as the corrosive poop of generations of nesting birds […]
The joint U.S.-European Sentinel-6 Michael Freilich is the next in a line of Earth-observing satellites that will collect the most accurate data yet on sea level and how it changes over time. With millimeter-scale precision, data from this mission will allow scientists to precisely measure sea surface height […]
The U.S.-based shark research team Ocearch tagged their largest great white in the Northwest Atlantic so far and named her after a Mi’kmaw grandmother figure. Nukumi, pronounced noo-goo-mee, was tagged on Friday morning near West Ironbound Island, south of Lunenburg, N.S. She’s more than five metres long, weighs 1,606 kilograms and is […]
A river’s only consistent attribute is change. As the Greek philosopher Heraclitus remarked, “No man ever steps in the same river twice.” Although this dynamic nature is often out of sight and mind, forgetting about it has led to many a historical catastrophe. Recently, UC Santa Barbara geomorphologist […]
A pair of previously captive beluga whales have taken their first swim in their new open-water sea sanctuary off Iceland’s south coast. The whales — called Little White and Little Grey — were captured in Russian waters and sold to Changfeng Ocean World aquarium in Shanghai over ten […]
The Greenland ice sheet is on track to lose mass at about four times the fastest rate observed over the past 12,000 years. At its current trajectory, such melting would dump huge quantities of freshwater into the sea, raising global sea levels and disrupting ocean currents, scientists concluded […]
The climate crisis is heating up nights faster than days in many parts of the world, according to the first worldwide assessment of how global heating is differently affecting days and nights. The findings have “profound consequences” for wildlife and their ability to adapt to the climate emergency, the researchers said, […]
Vaquita porpoises have puzzled scientists since their discovery in 1958. Regrettably, their populations have gotten much smaller over time due to illegal fishing practices. In this post, we highlight that while these “little cows” may be difficult to protect, we should try everything we can to save them. […]
Coral reefs are some of the richest hotspots of biodiversity on the planet. The warm water reefs of the Pacific Ocean and Caribbean Sea are well know, but they don’t only occur in warm waters. In some of the oceans coldest, darkest depths they are thriving. The deep […]
Great documentary! Cocos Island protrudes from the Pacific Ocean – a lone volcano peeking out of the blue grey waters, off the Costa Rican coast. The island has many similarities with the fictional Treasure Island, penned by Scottish author Robert Louis Stevenson, himself an intrepid traveler. Maybe he […]
