Ten sample tubes, capturing an amazing variety of Martian geology, have been deposited on Mars' surface so they could be studied on Earth in the future. Less than six weeks after it began , construction of the first sample depot on another world is complete. Confirmation that NASA's Perseverance Mars rover successfully dropped the 10th and final tube planned for the depot was received around 5 p.m. PST (8 p.m. EST) Sunday, Jan.

Explosions from a sinking ship are among the unexpected sounds detected by 50 highly sensitive seismometers placed on the floor of the Atlantic Ocean as part of an international collaboration led by UCL researcher Professor Ana Ferreira. The seismometers, which have now been collected after spending a year at the bottom of the ocean, record the Earth's ground motions on the sea floor and thus capture the Earth's "pulse".

The CO2 levels in the atmosphere continue to rise as we strive to reduce our emissions. Now, an international team of researchers proposes a radical solution: pour crushed stone into the sea and it will empower the water to absorb CO2 from the atmosphere.

News from To mark the meteorological start of winter today (1 December 2023), Leipzig University's Office for University Communications is publishing its first multimedia story entitled "In search of snow's secrets".

Natural Hazard Research and Geoarchaeology team of JGU is investigating coastal developments in Western Greece over the last 11,600 years The ancient Greek historian Strabo referred to the presence of an important shrine located on the west coast of the Peloponnese some 2,000 years ago. Remains of such an Archaic temple have now been uncovered at the Kleidi site near Samikon, which presumably once formed part of the sanctuary of Poseidon.

What can hidden motions underground tell us about earthquakes, eruptions, and even climate change? NASA scientists are using data gathered 400 miles above Earth to find out. Creeping, rising, falling, slipping - some parts of Earth are in perpetual motion. The movements are usually too tiny for human senses to notice, but they offer clues about more significant changes happening inside volcanoes, along fault lines, and where tectonic plates meet and clash.

Using sand and rock, MIT senior Aviva Intveld tells stories of ancient climates. Aviva Intveld, an MIT senior majoring in Earth, atmospheric, and planetary sciences, is accustomed to city life.

Life has existed on Earth for billions of years. Stabilising mechanisms have helped our planet remain habitable to this day.

The lander's team has tried to contact the spacecraft twice without response, leading them to conclude it has run out of energy. NASA's InSight mission has ended after four years of collecting unique science on Mars.

Aix-Marseille Université joined the Interreg Alpine Space project "AlpSatellites", co-funded by the EU.

Researchers from the University of Bonn install extremely sensitive measuring instrument at Todenfeld Observatory Researchers at the University of Bonn have installed a superconducting gravimeter at the Todenfeld observatory a few kilometers from the town of Rheinbach.

The powerful swells can break a container ship in half. Lisa Beal had heard mariners talk about the force of such waves, but she never really believed them, dismissing their accounts as tall sea tales.

Développement durable On the occasion of World Climate Day, physicist Davide Faranda, at the Environmental Transition Institute at Sorbonne University, looks back at the mixed results of COP 27 held in Sharm el-Sheikh, Egypt.

Enhancing and protecting Canada's carbon stocks is essential but insufficient to meet GHG emission targets: expert panel report Enhancing carbon storage in natural ecosystems could put a small but si

SFU professors Kirsten Zickfeld and Karen Kohfeld are part of an expert panel contributing to a new report released this week investigating the potential contribution of nature-based climate solutions (NBCS) to meeting Canada's climate change mitigation commitments. Zickfeld, Kohfeld and other contributing researchers comprise the Expert Panel on Canada's Carbon Sink Potential from the Council of Canadian Academies (CCA).

Those selected for these positions receive additional support to pursue their research and develop their careers.

Internationally recognized atmospheric scientist and Distinguished Senior Researcher at Empa: Dominik Brunner is a scientist who has explored his subject area from many angles - with a weatherproof motivation and curiosity that drives him to this day.

A warming climate is causing a decline in sea ice in the Arctic Ocean, where loss of sea ice has important ecological, economic and climate impacts. On top of this long-term shift due to climate change are weather events that affect the sea ice from week to week. The strongest Arctic cyclone ever observed poleward of 70 degrees north latitude struck in January 2022 northeast of Greenland.

The ocean has always had a special appeal to atmospheric sciences professor Amy Clement. Growing up in coastal Massachusetts, and on Long Island, New York, she often spent free time exploring the beach, or swimming in the Atlantic Ocean.

Snowcapped mountains not only look majestic - They're vital to a delicate ecosystem that has existed for tens of thousands of years. Mountain water runoff and snowmelt flows down to streams, rivers, lakes, and oceans - and today, around a quarter of the world depends on these natural "water towers" to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support.

A UCL-led team of archaeologists found spear tips and other stone tools that have been submerged under the English Channel since the last ice age, providing new clues about our Neanderthal past.

2022 WJ1 was a tiny asteroid on a collision course with Earth. But astronomers saw it coming, and NASA's Scout impact hazard assessment system calculated where it would hit. In the early hours of Saturday, Nov. 19, the skies over southern Ontario, Canada, lit up as a tiny asteroid harmlessly streaked across the sky high in Earth's atmosphere, broke up, and likely scattered small meteorites over the southern coastline of Lake Ontario.

A cosmic drama unfolded over southern Ontario on the night of Friday, Nov. 18, triggering an international collaboration and a meteorite hunt.

Satellite observations and computer simulations are important tools for understanding past changes in Earth's climate and for projecting future changes. However, satellite observations consistently show less warming than climate model simulations from 1979 to the present, especially in the tropical troposphere (the lowest ~15km of Earth's atmosphere).

Utrecht scientists developed the OceanParcels computer program that shows how plastic, bacteria and other particles move around the ocean.

This year's Chesapeake Bay "dead zone” was the 10th-smallest observed since 1985, according to findings released today by the Chesapeake Bay Program and its partners, including the University of Michigan.

The full professor of Geography at the University of Valencia Josep Vicent Boira has studied what the landscape of El Grau of València was like in pre-industrial times through 16 engravings and maps by different authors.

The Government of Canada announced today that Canadensys Aerospace has received a contract to design and build Canada's first lunar rover, which will be sent to the Moon's south pole region as early as 2026.

Terrestrial and aquatic food webs respond differently to changes in the environment. Understanding these differences is fundamental to identifying the species most important to an ecosystem and to effectively protecting biodiversity. This is shown by a study led by the research institutes Eawag and WSL and published in the journal Nature Communications .

Globally, the coastal lagoons of Lagos (Nigeria), Sakumo (Ghana) and Bizerte (Tunisia) —close to large urban centres and without waste and sewage treatment systems— are among the most affected water ecosystems of this nature by microplastic pollution. However, the highest concentrations of microplastics have been detected in Barnes Sound and other small lagoons in a protected area in the north of Florida Bay (USA), a particular case that can be explained by the transport of microplastics carried by hurricanes from polluted areas.
