Reconstruction shows increased global warming trends since 1850s
To better understand how temperatures have increased, an international team led by researchers at Sun Yat-Sen University in China has released a newly merged global surface temperature dataset, including reconstructed land and marine measurements from the 1850s to 2018. The study provides evidence that there was a consistent increased warming trend compared with previous estimations. (2021-01-28)

Arctic ocean expedition advances climate modeling
In-situ cloud, radiation, and surface energy budget data collected by a September 2014 expedition of the Japanese Research Vessel Mirai from a stationary point in the ice-free Arctic Ocean were used to investigate the skill of regional climate models. Although most near-surface meteorological parameters were adequately captured by most models, certain important discrepancies were identified, such as the failure to capture unstable low-level cloud stratification, and the partitioning of ice clouds and liquid clouds.

Nuclear war could trigger big El Niño and decrease seafood
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy - at least in the equatorial Pacific.

How will seafarers fare once automated ships take over? Scientists predict the future
Researchers from the Korea Maritime and Ocean University show that automation in the shipping industry will lead to an overall increase in shore-based jobs. However, they warn that this will have to be complemented with concerted policy measures to provide the necessary technical training to job seekers and veteran seafarers who will need to adapt to the new technological paradigm.

Increasing ocean temperature threatens Greenland's ice sheet
Scientists at the University of California, Irvine and NASA's Jet Propulsion Laboratory have for the first time quantified how warming coastal waters are impacting individual glaciers in Greenland's fjords. Their work, the subject of a recent Science Advances study, can help climate scientists better predict global sea level rise from the increased melting. (2021-01-25)

Antarctica: the ocean cools at the surface but warms up at depth
Scientists from the CNRS, CNES, IRD, Sorbonne Université, l'Université Toulouse III - Paul Sabatier and their Australian colleagues, with the support of the IPEV, have concluded that the slight cooling observed at the surface of the Southern Ocean hides a rapid and marked warming of the waters, to a depth of up to 800 metres. These results were obtained thanks to unique data acquired over the past 25 years. (2021-01-21)

Stuck in a rut: Ocean acidification locks algal communities in a simplified state
Researchers from the University of Tsukuba have found that ocean acidification limits algal communities to a state of low diversity and complexity. Communities grown in waters rich in carbon dioxide (CO2) were dominated by turf algae, and had low biodiversity, ecological complexity and biomass. Communities grown under acidic conditions and then transferred to waters that weren't CO2-enriched increased their biodiversity and complexity, showing that they can recover if CO2 emissions are significantly reduced.

Human-induced climate change caused the northwestern Pacific warming record in August 2020
A new study led by National Institute for Environmental Studies researchers, published in the journal Geophysical Research Letters, revealed that the record-warm sea surface temperature over the northwestern Pacific in August 2020 could not be expected to occur without human-induced climate changes. Such extremely warm condition is likely to become a new normal climate in August by the mid-21st century, needing the prompt implementation of adaptation measures for anthropogenic global warming.

'Ocean 100': Small group of companies dominates ocean economy
Most of the revenues extracted from use of the world's oceans is concentrated among 100 transnational corporations. Dubbed the ''Ocean 100'' by researchers at Duke University and Stockholm University, these ''blue economy'' companies collectively generated $1.1 trillion in revenues in 2018, according to research published Wednesday in the journal Science Advances. If the group were a country, it would have the world's 16th-largest economy, roughly equivalent to the gross domestic product (GDP) of Mexico. (2021-01-13)

A new study conducted at the New England Aquarium finds that as climate change causes the ocean to warm, baby sharks are born smaller, exhausted, undernourished, and into environments that are already difficult for them to survive in. (2021-01-12)

New analysis highlights importance of groundwater discharge into oceans
An invisible flow of groundwater seeps into the ocean along coastlines all over the world. Scientists have tended to disregard its contributions to ocean chemistry, focusing on the far greater volumes of water and dissolved material entering the sea from rivers and streams, but a new study finds groundwater discharge plays a more significant role than had been thought. (2021-01-08)

Study reveals jellyfish create a 'virtual wall' to enhance performance
New discovery finds that Jellyfish create a ''ground effect,'' similar to how air squeezes between an airplane and ground during take-off, which builds pressure and a force that boosts performance. Never before has it been proven that an animal can create this phenomenon away from a solid boundary, let alone the open ocean. (2021-01-08)

The new face of the Antarctic
In the future, the Antarctic could become a greener place and be colonised by new species. At the same time, some species will likely disappear. (2021-01-06)

In changing oceans, sea stars may be 'drowning'
New Cornell University-led research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress - literally 'drowning' in their own environment - as elevated microbial activity derived from nearby organic matter and warm ocean temperatures rob the creatures of their ability to breathe. (2021-01-06)

Hawai'i drought during El Niño winter? Not always, according to new research
El Niño events have long been perceived as a driver for low rainfall in the winter and spring in Hawai'i, creating a six-month wet-season drought. However, a recent study by researchers in the University of Hawai'i at Mānoa revealed the connection between Hawai'i winter rainfall and El Niño is not as straightforward as previously thought.

Ocean heatwave has triggered new toxic algal blooms on the US west coast
Ocean warming has created a toxic hotspot of harmful algae on the west coast of the US, shows a new study led by the US National Oceanic and Atmospheric Administration's (NOAA) Northwest Fisheries Science Center. The neurotoxins produced by these algae poison marine wildlife and humans, and researchers and local communities are learning to forecast and adapt to these recurring environmental hazards. (2020-12-14)

The moon controls the release of methane in Arctic Ocean
The moon controls one of the most formidable forces in nature - the tides that shape our coastlines. Tides, in turn, significantly affect the intensity of methane emissions from the Arctic Ocean seafloor. High tides may even counter the potential threat of submarine methane release from the warming Arctic. (2020-12-14)
