Argentina’s Deep Sea Is More Biodiverse Than Scientists Thought
extent until this expedition. The team found Bathelia reefs 600 kilometers (373 miles) further south than its known range, at 43.5° latitude.ROV pilots filmed the remains of a deceased whale that had dropped to the seafloor, called a whalefall, at about 3,890 meters deep during a dive on the Salado-Colorado Kilometer scarp in the Argentine Basin. Whale falls offer up thousands of years of nourishment to a place accustomed to scarcity. From large scavengers to invisible microbes and bone-eating Osedax worms, there is something for all creatures that happen upon a whale fall. Once organic matter has

Arctic Sea Ice Hits Record Low Maximum Extent for the Year
Arctic sea ice has likely reached its maximum extent for the year, at 14.33 million square kilometers (5.53 million square miles) on March 22, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder.The 2025 maximum sea ice extent is the lowest in the 47-year satellite record, falling short of the previous record low of 14.41 million square kilometers (5.56 million square miles) set on March 7, 2017.“This new record low is yet another indicator of how Arctic sea ice has fundamentally changed from earlier decades,” said NSIDC senior
Kraken Robotics Acquires 3D at Depth
in water depths of more than 300m, and capabilities like non-contact vibration and temperature measurement. 3D at Depth’s expertise in Remote Operations also enables scalable, fully remote metrology solutions.3D at Depth’s headquarters and production facility are based in Longmont, Colorado with offshore service operations based out of Houston, Texas, and satellite offices in Norwich and Aberdeen, UK.
NOAA Scientist Dismissals Spark Protests
More than 1,000 demonstrators gathered outside the National Oceanic and Atmospheric Administration (NOAA) building in Boulder, Colorado, on Monday, protesting sweeping layoffs imposed by the Trump administration. According to two current employees, the cuts affected more than 10% of the scientific workforce at the facility.The rally was spearheaded by former U.S. Congressman David Skaggs, a Democrat from Colorado, after whom the NOAA building in Boulder is named. Skaggs, initially expecting only around 100 participants, was surprised by the large turnout, with police estimating attendance at over 1,000.
Warming Predictions Point to Need for Adaption as well as Decarbonization
other extremes. This study suggests that, even in the best case scenario, we are very likely to experience conditions that are more severe than what we've been dealing with recently," said Stanford Doerr School of Sustainability climate scientist Noah Diffenbaugh, who co-authored the study with Colorado State University climate scientist Elizabeth Barnes.For the new study, Diffenbaugh and Barnes trained an AI system to predict how high global temperatures could climb, depending on the pace of decarbonization. They trained the AI with temperature and greenhouse gas data from vast archives of climate
Arctic Sea Ice Could Reach Turning Point by 2027
The first summer on record that melts practically all of the Arctic’s sea ice, an ominous milestone for the planet, could occur as early as 2027.That’s according to an international research team, including University of Colorado Boulder climatologist Alexandra Jahn and Céline Heuzé from the University of Gothenburg in Sweden. The team used computer models to predict when the first ice-free day could occur in the northernmost ocean.When the Arctic Ocean has less than 1 million square kilometers of ice, scientists say the Arctic is ice free.In September, the National Snow and

It was described and named, meaning scientifically proven to be new, by local researchers from the universities of Stellenbosch and Cape Town, and experts from Santa Barbara Museum of Natural History and the University of Colorado Boulder.The rare and miniature isopodFinally, the third new species is Pseudionella pumulaensis. This is a parasitic isopod – a tiny crustacean.It was discovered in Pumula, KwaZulu-Natal, a region known for its high biodiversity. This isopod has a rather sinister survival strategy: it attaches
Arctic Sea Ice Reaches Seventh Lowest Extent on Record
Arctic sea ice has likely reached its minimum extent for the year, at 4.28 million square kilometers (1.65 million square miles) on September 11, 2024, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder.The 2024 minimum is ranked seventh lowest in the 46-year satellite record. The last 18 years are the lowest 18 Arctic sea ice extents in the satellite record.The overall, downward trend in the minimum extent from 1979 to 2024 is 12.4 percent per decade relative to the 1981 to 2010 average. From the linear trend, the loss of sea ice is about 77
