Did Venus ever have oceans?
The planet Venus can be seen as the Earth's evil twin. At first sight, it is of comparable mass and size as our home planet, similarly consists mostly of rocky material, holds some water and has an atmosphere. Yet, a closer look reveals striking diff.....»»
Another building block of life can handle Venus" sulfuric acid
Venus is often described as a hellscape. The surface temperature breaches the melting point of lead, and though its atmosphere is dominated by carbon dioxide, it contains enough sulfuric acid to satisfy the comparison with Hades......»»
Feeding coral reefs can aid their recovery from bleaching events
Coral reefs will continue to experience severe heat stress as rising temperatures cause the oceans to become unbearably hot—but a new study shows that altering their feeding habits could allow local populations to avoid total extinction......»»
Evaluating changes in dissolved inorganic carbon in the Greenland Sea
To know whether we are complying with emission treaties, all CO2 must be traceable. Incomplete bookkeeping recently sent scientists on a search in the Greenland Sea. Their research is published in the Journal of Geophysical Research: Oceans......»»
Oceanic life found to be thriving thanks to Saharan dust blown from thousands of kilometers away
Iron is a micronutrient indispensable for life, enabling processes such as respiration, photosynthesis, and DNA synthesis. Iron availability is often a limiting resource in today's oceans, which means that increasing the flow of iron into them can in.....»»
Tropical cyclone intensity exacerbated by increasing depth of ocean mixed layer, finds study
Tropical cyclones can have severe consequences for both the marine and terrestrial environments, as well as the organisms and communities who inhabit them. In the oceans, there can be alterations in sea surface temperature that disrupt biological pro.....»»
So where does the oceans" plastic waste come from?
In the form of bottles, tires, packaging and piping, millions of tons of plastic waste are dumped every year in the world's waterways, often ending up in the oceans......»»
Lower shipping emissions may lead to higher global temperatures
Products that we depend on and use every day arrive by way of massive container ships to ports around the world. But the maritime shipping industry is also responsible for polluting the air and oceans with sulfur dioxide, which can negatively affect.....»»
Environment takes center stage as global summits loom
Global warming. Disappearing plant and animal species. Fertile land turning to desert. Plastic in the oceans, on land, and the air we breathe......»»
How the oceans" most abundant bacteria impact global nutrient flows
If you were to collect all the organisms from the ocean surface down to 200 meters, you'd find that SAR11 bacteria, though invisible to the naked eye, would make up a fifth of the total biomass. These bacteria, also known as Pelagibacterales, have ev.....»»
Parker Solar Probe lines up for final Venus flyby
NASA's Parker Solar Probe executed a short maneuver on Aug. 26 that kept the spacecraft on course for the mission's seventh and final planned Venus flyby on Nov. 6......»»
Sharks are abandoning stressed coral reefs in warming oceans, study finds
Gray reef sharks are having to abandon the coral reefs they call home in the face of warming oceans, new research finds......»»
The world is pumping out 57 million tons of plastic pollution a year
The world creates 57 million tons of plastic pollution every year and spreads it from the deepest oceans to the highest mountaintop to the inside of people's bodies, according to a new study that also said more than two-thirds of it comes from the Gl.....»»
New study reveals urgent need for "Blue Justice" in the emerging blue economy
A new study has highlighted a critical issue within the rapidly developing Blue Economy; the need for "Blue Justice"—a new concept that originated from this study. As countries and industries increasingly turn to the oceans for economic growth, thi.....»»
Composite plastic degrades easily with bacteria, offers environmental benefits
Billions of tons of plastic waste clutter our world. Most of it has accumulated on the ground and in the oceans or disintegrated into tiny particles known as microplastics that pollute the air and the water, penetrating vegetation and the bloodstream.....»»
Investigation reveals global fisheries are in far worse shape than we thought—and many have already collapsed
When fish are taken from our oceans faster than they can reproduce, their population numbers decline. This over-fishing upsets marine ecosystems. It's also bad for human populations that rely on fish for protein in their diets......»»
A Rare Coincidence of La Niña Events Will Weaken Hurricane Season
The oceans have produced a rare coincidence of the Pacific and Atlantic Niñas, which will lessen the severity of the hurricane season—though 2024 still remains a highly active year......»»
Land-sea "tag-team" devastated ocean life millions of years ago, reveal scientists
Scientists have revealed how a "tag-team" between the oceans and continents millions of years ago devastated marine life—and altered the course of evolution on Earth......»»
Cultured zooplankton provide new avenue to monitor and rid oceans of microplastic pollutants
Testing for levels of microplastic contamination in marine plankton aims to help develop new ways to assess and manage the rising global pollution problem, Flinders University experts say......»»
Astronomers discover spectacular increase in the deuterium to hydrogen ratio in Venus"s atmosphere
Thanks to observations by the Solar Occultation in the Infrared (SOIR) instrument on the Venus Express space probe of the European Space Agency (ESA), researchers have discovered an unexpected increase in the abundances of two water molecule variants.....»»
How fly fishing strengthens our connection with wildlife and fosters conservation efforts
Whether it's to reset our mental health or simply to take time out from the hurly-burly of work and urban life, many of us head for oceans and rivers to enjoy their restorative capacities......»»
