A 30-year reconstruction of the Atlantic meridional overturning circulation shows no decline
Climate model and paleo-oceanographic research suggests that the AMOC may have been declining for decades or even centuries before this; however direct observations are sparse prior to 2004, giving only…
Freshwater outflow from Beaufort Sea could alter global climate patterns
The Beaufort Sea, the Arctic Ocean’s largest freshwater reservoir, has increased its freshwater content by 40 percent over the last two decades, putting global climate patterns at risk. A rapid…
Claim: Marine heatwaves becoming more intense, more frequent
Thinning surface layer of ocean leaves waters more susceptible to extreme warming events UNIVERSITY OF COLORADO AT BOULDER Research News When thick, the surface layer of the ocean acts as…
Modern microbes provide window into ancient ocean
Step into your new, microscopic time machine. Scientists at the University of Colorado Boulder have discovered that a type of single-celled organism living in modern-day oceans may have a lot…
Preventing Ecosystem Collapse 3: Seagrass
The good news is most of the human factors that have reduced seagrass meadows can be and are being remedied. Furthermore, rising levels of carbon dioxide will benefit their growth…
Preventing Ecosystem Collapse: Alaska’s Kelp Forests
Although these biological interactions control ecosystem shifts between kelp forests and urchin barrens, climate factors play a role, and in a most positive way. Otters are limited by ice. In…
Computational Hubris
Trillions of plastic debris fragments are afloat at sea, creating the “perfect storm” for microbial colonization. Introduced more than 50 years ago, plastic substrates are a novel microbial habitat in…
Claim: Marine heatwaves are human made
“The recent heatwaves have had a serious impact on marine ecosystems, which need a long time to recover afterwards – if they ever fully recover,” explains Charlotte Laufkötter.A huge increase…
Undersea earthquakes shake up climate science
In a new paper publishing in Science, the researchers show how they are able to make use of existing seismic monitoring equipment, as well as historic seismic data, to determine…
Ocean carbon uptake widely underestimated
Previous estimates of the movement of carbon (known as “flux”) between the atmosphere and oceans have not accounted for temperature differences at the water’s surface and a few metres below.
Algorithms in Ocean Chemistry: a review
For those wanting a deep dive on ocean physical chemistry, this new ebook is a much better and more detailed explanation than I could ever hope to provide
The Oceans Won’t Suffocate!
Unfortunately, scientific journals also succumb to the same profit incentives. Indeed, pictures of thousands of suffocated fish floating belly-up is very disturbing. However, media outlets amplified our fears with headlines…
Florida current is weaker now than at any point in the past century
A key component of the Gulf Stream has markedly slowed over the past century–that’s the conclusion of a new research paper in Nature Communications published on August 7.
Arctic Ocean changes driven by sub-Arctic seas
New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.
First direct evidence of ocean mixing across the gulf stream
New research provides the first direct evidence for the Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for…

There is no escaping from climate change, even in the deep sea
Hokkaido University Even though the deeper layers of the ocean are warming at a slower pace than the surface, animals living in the deep ocean are more exposed to climate…
Study: Ancient ocean oxygen levels associated with changing atmospheric carbon dioxide
A Texas A&M-led study analyzed ocean floor sediment cores to provide new insights into the relationship between deep ocean oxygenation and atmospheric carbon dioxide levels in the 50,000 years before…
HKU marine biologist and international team unveil impacts of heatwave on reef fishes
The University of Hong Kong The marine heatwave of 2016 was one of longest and hottest thermal anomalies recorded on the Great Barrier Reef in Australia, influencing multiple species of…
Climate change could threaten sea snails in mid-Atlantic waters
