Tracking down climate change with radar eyes
Over the past 22 years, sea levels in the Arctic have risen an average of 2.2 millimeters per year. This is the conclusion of a research team after evaluating 1.5 billion radar measurements of various satellites using specially developed algorithms.

Super salty, subzero Arctic water provides peek at possible life on other planets
Researchers have discovered thriving communities of bacteria in Alaskan 'cryopegs,' trapped layers of sediment with water so salty that it remains liquid at below-freezing temperatures. The setting may be similar to environments on Mars, Saturn's moon Titan, or other bodies farther from the sun.

DNA analysis reveals cryptic underwater ecosystem engineers
They look like smears of pink bubblegum on the rocks off British Columbia's coast, indistinguishable from one another. But a new DNA analysis of coralline algae has revealed a wealth of different species -- a diversity that could hold the key to protecting critical underwater habitats like kelp forests.

Coral skeleton crystals record ocean acidification
The acidification of the oceans is recorded in the crystals of the coral skeleton. This is a new tool for studying past environmental changes and combating climate change. Such is the main conclusion of a study led by the Spanish scientist Ismael Coronado Vila, from the Institute of Paleobiology in Warsaw (Poland).

Researchers discover ice is sliding toward edges off Greenland Ice Sheet
Ice on the Greenland Ice Sheet doesn't just melt. The ice actually slides rapidly across its bed toward the ice sheet's edges. As a result, because ice motion is from sliding as opposed to ice deformation, ice is being moved to the high-melt marginal zones more rapidly than previously thought.

New research helps predict locations of blue whales so ships can avoid them
A new model based on daily oceanographic data and the movements of tagged whales has opened the potential for stakeholders to see where in the ocean endangered blue whales are most likely to be so that ships can avoid hitting them.

Coral reefs shifting away from equator
Coral reefs are retreating from equatorial waters and establishing new reefs in more temperate regions, according to new research. The researchers found that the number of young corals on tropical reefs has declined by 85 percent -- and doubled on subtropical reefs -- during the last four decades.

A clearer picture of global ice sheet mass
Fluctuations in the masses of the world's largest ice sheets carry important consequences for future sea level rise, but understanding the complicated interplay of atmospheric conditions, snowfall input and melting processes has never been easy to measure due to the sheer size and remoteness inherent to glacial landscapes.

Paris Agreement does not rule out ice-free Arctic
A research team reveals a considerable chance for an ice-free Arctic Ocean at global warming limits stipulated in the Paris Agreement.

Istanbul: Seafloor study proves earthquake risk for the first time
Istanbul is located in close proximity to the North Anatolian fault, a boundary between two major tectonic plates where devastating earthquakes occur frequently. Using an autonomous measuring system on the seafloor, researchers have now for the first time measured deformation underwater and detected a considerable build-up of tectonic strain below the Marmara Sea near Istanbul.

Indian Ocean causes drought and heatwaves in South America
Researchers have revealed that atmospheric waves originating from convection over the Indian Ocean had a dramatic impact on climate conditions over South America and South Atlantic, leading to drought and marine heatwaves. Importantly, these conditions are not a one-off and are likely to happen again.

Hundreds of sharks and rays tangled in plastic
Hundreds of sharks and rays have become tangled in plastic waste in the world's oceans, new research shows.

Scientists discover the biggest seaweed bloom in the world
The record-breaking belt of brown algae stretches from West Africa to the Gulf of Mexico -- and it's likely here to stay, says a team.

More 'reactive' land surfaces cooled the Earth down
In a new study, researchers show that a paradigm on a global temperature drop that started around 15 million years ago cannot be upheld. With the help of a computer model they explain the Earth's cooling with an increased 'reactivity' of the land surface that has led to a decrease in carbon dioxide in the atmosphere, reducing the Earth's natural green house effect.

Remote but remarkable: Illuminating the smallest inhabitants of the largest ocean desert
The South Pacific Gyre is an ocean desert. However, due to its vast size the microbial inhabitants of the South Pacific Gyre contribute significantly to global biogeochemical cycles. In an unparalleled investigation, scientists have now made a comprehensive inventory of the microbial community of the South Pacific Gyre. This insight was achieved through the development of a novel tool that enables the on-board analysis of the ocean's smallest inhabitants.

How to protect corals facing climate change
The best way to protect corals threatened by climate change is to conserve a wide range of their habitats, according to a new study. The finding likely applies to conservation efforts for many other species in the ocean and on land, including trees and birds.

New measurements shed light on the impact of water temperatures on glacier calving
Calving, or the breaking off of icebergs from glaciers, has increased at many glaciers along the west coast of Svalbard. Now, researchers have shown that, whilst subsurface water temperatures are the most important driver of frontal mass loss, they are not as important as previously thought.

New study solves mystery of salt buildup on bottom of Dead Sea
New research explains why salt crystals are piling up on the deepest parts of the Dead Sea's floor, a finding that could help scientists understand how large salt deposits formed in Earth's geologic past.

Corals in Singapore likely to survive sea-level rise
Marine scientists found that coral species in Singapore's sedimented and turbid waters are unlikely to be impacted by accelerating sea-level rise.
