Fortunately Glasgow has only been inundated with a flood of international oceanographers 🌊. Expect to hear us in your pubs, restaurants and streets talking about #ClimateChange, #MarineEcology, #OceanCirculation, #mCDR and, yes, #SeaLevelRise. Thanks for having us and feel free to ask us questions!

AMOC Failure Once Unfolded in Under Twenty Years Extreme Ice Age eruptions triggered rapid collapses of the Atlantic circulation, driving sudden climate shifts across the Northern Hemisphere

🌊 The AMOC Has Collapsed in Decades Before ⚠️

Climate records show the Atlantic circulation can drop fast. One massive eruption once pushed it into a weak state that lasted millennia.

Does the Gulf Stream Keep Europe Warm? Europe's mild climate is not caused by the Gulf Stream alone. The warm water that reaches Europe is carried mainly by the North Atlantic Current, the northeast extension of the Gulf Stream and part of the Atlantic Meridional Overturning Circulation. Atmospheric westerly winds explain most of Europe's winter warmth relative to the same latitudes in eastern North America, with ocean heat transport providing an important but secondary contribution.

Does the Gulf Stream singlehandedly warm Europe? Not quite - wind patterns and the North Atlantic Current do the heavy lifting. Want the full climate picture? #AMOC #EuropeClimate #GulfStream #NorthAtlanticCurrent #OceanCirculation

Under Antarctica's Ice, Scientists Uncover a Hidden Network of Over 300 Giant Canyons With Serious Implications for Ocean Circulation A new scientific atlas has just redrawn the map of Antarctica’s seafloor—and what it reveals could alter how researchers model sea-level rise, ocean circulation, and the continent’s past. The study, published in Marine Geology and led by researchers from the...

Most detailed map of Antarctic submarine canyons reveals climate role • Muser Press Submarine canyons off Antarctica are larger, deeper, and more complex than previously thought – and their role in regulating climate may be more significant

New #map reveals 332 submarine canyons under Antarctic seas – some over 4,000 m deep – with major implications for #oceancirculation, #icemelt and #climatechange. 'Marine Geology' | DOI: doi.org/10.1016/j.ma...

A new high resolution mapping exercise has revealed hundreds more Antarctic submarine canyons.

The study shows they may have a much greater influence on ocean circulation, ice-shelf thinning and climate change.

5/7 "Unlikely isn't impossible," cautions co-author Jonathan Baker. Their models suggest the AMOC could collapse if a strong Pacific circulation developed, but in all scenarios, this remained too weak to counteract the stabilizing Southern Ocean upwelling.
