Atlantic Ocean near Bermuda is warmer and more acidic than ever, 40 years of observation show

Data spanning 40 years shows changes in the subtropical North Atlantic Ocean near the island of Bermuda, including warming by 1°C

Atlantic Ocean near Bermuda is warmer and more acidic than ever, 40 years of observation show
2023-12-08
(Press-News.org) Decade-long ocean warming which impacts ocean circulation, a decrease in oxygen levels that contributes to changes in salinification and nutrient supply, and ocean acidification are just some of the challenges the world’s oceans are facing.

In 1988, a comprehensive sustained ocean time-series of observations, called the Bermuda Atlantic Time-series Study (BATS), began at a site about 80 km southeast of the island of Bermuda. There, scientists take monthly samples of the physics, biology, and chemistry of the ocean’s surface and depths. In a new paper published in Frontiers in Marine Science, researchers have now presented the latest findings from this monitoring effort.

“We show that the surface ocean in the subtropical North Atlantic Ocean has warmed by around 1°C over the past 40 years. Furthermore, the salinity of the ocean has increased, and it has lost oxygen,” said author Prof Nicholas Bates, an ocean researcher at the Bermuda Institute of Ocean Sciences, a unit of the Julie Ann Wrigley Global Futures Laboratory at Arizona State University (ASU) and professor in the School of Ocean Futures at ASU. “In addition, ocean acidity has increased from the 1980s to the 2020s.”

Warm, salty, deoxidized, acidic

At the BATS monitoring station, ocean surface temperatures have increased by around 0.24°C each decade since the 1980s. Added up, the ocean is around 1°C warmer now than it was 40 years ago. In the last four years, ocean temperatures have also risen more sharply than in the previous decades, the researchers found.

Not only have the monitored waters gotten warmer, but also more saline at the surface, meaning more salt is dissolved in the water. Like surface temperature, this saltiness has disproportionally increased during the last few years, the newest data showed. “We suspect this is part of the broader, more recent trends and changes in ocean temperatures and environmental changes, like atmospheric warming and having had the warmest years globally,” Bates said.

At the same time, the data indicated that over the last 40 years the amount of oxygen available to living aquatic organisms has decreased by 6%. Acidity values, too, have changed: the ocean is now 30% more acidic than it was in the 1980s, resulting in lower carbon ion concentrations. This can, among other things, affect shelled organisms’ ability to sustain their shells.

“The ocean chemistry of surface waters in the 2020s is now outside of the seasonal range observed in the 1980s and the ocean ecosystem now lives in a different chemical environment to that experienced a few decades ago,” Bates explained. “These changes are due to the uptake of anthropogenic CO2 from the atmosphere.”

Importance of long-time data

Collecting data over extended time periods is important to predict upcoming shifts in conditions. “These observations give a sense of the rate of change in the recent past of ocean warming and ocean chemistry. They provide key indications of future changes in the next decades,” said Bates. “They also are proof of regional and global environmental change and the existential challenges we face as individuals and societies in the near future.”

The monitoring stations providing the data for the present study are just two out of the several long-term sustained ocean time-series sites located throughout the world’s oceans. Stations off Hawaii, the Canary Islands, Iceland, and New Zealand are also key to monitoring long-term oceanic changes. At some of those stations, similar processes have been observed, highlighting the challenges and complexities of understanding the long-term interactions between warming, salinification, and ocean acidification, the researchers said.

Battle of the AIs in medical research: ChatGPT vs Elicit
2023-12-08
Can AI save us from the arduous and time-consuming task of academic research collection? An international team of researchers investigated the credibility and efficiency of generative AI as an information-gathering tool in the medical field. The research team, led by Professor Masaru Enomoto of the Graduate School of Medicine at Osaka Metropolitan University, fed identical clinical questions and literature selection criteria to two generative AIs; ChatGPT and Elicit. The results showed that while ChatGPT suggested fictitious articles, Elicit was efficient, suggesting multiple references within a few minutes with the same level of accuracy as the researchers. “This ...

First hints of nuclear fission in cosmos revealed by models, observations

First hints of nuclear fission in cosmos revealed by models, observations
2023-12-08
LOS ALAMOS, N.M., Dec. 7, 2023 — The elements above iron on the periodic table are thought to be created in cataclysmic explosions like the merger of two neutron stars or in rare classes of supernovae. New research suggests fission may operate in the cosmos during the creation of the heavy elements. Combing through data on a variety of elements that reside in very old stars, researchers have found a potential signature of fission, indicating that nature is likely to produce superheavy nuclei beyond the heaviest elements on the periodic table. “People have thought fission was happening in the cosmos, but ...

Vocal Fry: A sonic feature of a diverse city #Acoustics23
2023-12-08
SYDNEY, Dec. 8, 2023 – Vocal fry has a bad reputation in American English. A subtype of creaky voice, a feature of speech that sounds gravelly and pulselike, this manner of speech is sometimes used to form judgment about the speaker. In many languages, the creaky tone changes the meaning of words, exhibited in Lango spoken in South Sudan or Jalapa Mazatec spoken in Mexico. Hannah White and her Department of Linguistics colleagues at Macquarie University researched how creaky voice is reflected in Australian English used in Sydney, and what factors influence its prevalence. She will present ...
