Radiocarbon dating at 1 cm resolution revealed event layers in a 40 cm core that X-ray and CT missed; some match recorded earthquakes of the 13th–20th centuries.
Researchers also recorded fewer calves and more entanglements; Olaf Meynecke says early sea ice melt and less food may be factors.
Geological records and simulations show that two earthquakes triggered subaqueous delta collapses in an Italian lake; the authors link the delta's instability to human-driven erosion.
A global simulation for 1960–2019 sorted land by groundwater recovery after drought: 57% resilient, 15% vulnerable, 26% unstable, where repeated droughts cut recovery capacity.
Researchers at Pukyong National University link the decline of Todarodes pacificus to marine heat waves. The current catch is one-sixteenth of the 2002 level.
Samples from 38 stations show that the molecular composition of dissolved organic matter in the Weddell Sea is set before dense shelf water mixes with warmer off-shelf water.
Researchers at Pukyong National University linked the collapse of the Japanese flying squid fishery in the East Sea to warming and heatwaves. Their projections show zero catch by the 2040s.
A review in The Innovation says high-spectral-resolution lidar on China's DQ-1 and Europe's EarthCARE replaces assumptions with measurement of subsurface plankton.
Seabed sediments from the Amundsen Sea show that glacial debris from the main West Antarctic outlet glaciers almost vanished in all earlier warm periods, the authors report.
Nitrogen isotopes in fossil plankton shells show Southern Ocean algae used about 40% less nutrients at the Eocene peak; a model links this to at least half of the CO2 rise.
Divers and land teams found a harbour section probably from the Augustan period and a building possibly used for wine production; samples should identify the quarry.
Researchers scanned three North Rim caves in 25 days and found that groundwater follows joint sets and rock dip, which links present-day flow paths to regional faulting and uplift.
Net sampling and sonar recorded steep drops in fishes, crustaceans and cephalopods after the 2010 spill. The authors found no natural cause and point to the spill.
Researchers dated hemipelagic mud from the Kumano Trough by radiocarbon of organic carbon at 0.5–1 cm steps. Some age anomalies match historical earthquakes, others match no known event.
Italian startup Sizable Energy completed offshore tests of seabed brine storage, a pumped-hydro analogue at sea. An integrated demonstrator with a data center is scheduled for the first half of 2027.
A team led by Tetsuro Hirono of Osaka Metropolitan University found traces of fault clay fluidization in 15-million-year-old rock, which may explain very large seafloor slip.
Satellite tags on 34 North Atlantic swordfish recorded 29 confirmed dives below 1,000 m. Their pattern fits environmental profiling during long migrations, though the mechanism is unresolved.
Two nearly complete Late Triassic skeletons show an armoured amphibian that, according to the authors, lived in fully marine conditions, without access to land or fresh water.
University of Copenhagen researchers dated eye lens tissue of female Arctic sharks by radiocarbon, since cartilage has no growth rings. Adults live over two hundred years.
A formation of rose coral Pachyseris covers about 5.7 hectares at depths of 14 to 65 meters. Genetic tests will show whether it is one organism or many fused colonies.
