Scientists believe the formation of the Isthmus of Panama is one of the most important geologic events causing an enormous impact on Earth’s climate and environment. Not only the Atlantic currents were forced northward causing what is known as the Gulf Stream helping to increase climate temperatures in Europe up to 10 degrees C during the winter season. In addition it also played a major role in biodiversity by bridging North and South America.

May 20 article , UCI News. Excerpt - In a study published today [May 20, 2024] in Proceedings of the National Academy of Sciences, the UC Irvine-led team said that widespread contact between ocean water and the glacier – a process that is replicated throughout Antarctica and in Greenland – causes “vigorous melting” and may require a reassessment of global sea level rise projections. #climatecrisis #globalwarming #sealevelrise #glaciers

[World Oceans Day] 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐬𝐞𝐚-𝐥𝐞𝐯𝐞𝐥 𝐫𝐢𝐬𝐞: 𝐢𝐦𝐩𝐫𝐨𝐯𝐢𝐧𝐠 𝐩𝐫𝐞𝐝𝐢𝐜𝐭𝐢𝐨𝐧𝐬 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐬𝐭𝐮𝐝𝐲𝐢𝐧𝐠 𝐭𝐡𝐞 𝐬𝐡𝐚𝐩𝐞 𝐨𝐟 𝐭𝐡𝐞 𝐬𝐞𝐚𝐛𝐞𝐝 Petermann #glacier in Greenland recently lost nearly 40% of its floating ice tongue, while just a few kilometres away, Ryder Glacier had been stable for decades. With the melting of marine glaciers draining into the #ocean constituting one of the largest uncertainties in projections of global #sealevel rise, a team of ocean mappers decided to look deeper into what processes could be influencing the formation and melting of glaciers. They discovered a surprising connection between the shape of the seabed and the size of glaciers. As part of #WorldOceanDay, this video looks at how better bathymetric #data can help improve sea-level rise predictions.

“Algae in the South Atlantic often quickly develop into enormous blooms that float and are carried with the meandering ocean currents. In this image, captured in November 2023, impressive green and blue swirls covering more than 360,000 sq km can be seen around the islands. (This makes it about the same area as Germany, which is 357,600 sq km.) The different colors are the result of sunlight reflecting off the chlorophyll contained in the microscopic plants” “Blooms in this area are quite common owing to the convergence of two strong oceanic currents: the warmer low-nutrient current from Brazil flowing southward and the colder Falkland current that travels northward. When the two currents meet, the resulting turbulence causes upwelling, which can drive large amounts of nutrients to the surface, which is partly responsible for phytoplankton blooms. These blooms are an important food source for many marine species.” https://lnkd.in/gj53QeFM

The massive 6.4 acre area stretches from Miami, Florida up to Charleston, South Carolina. According to the National Oceanic and Atmospheric Administration (NOAA) this is an area larger than the state of Vermont. The findings were described in a study published January 12 in the journal Geomatics.

Fin whales are making a giant comeback. 😍 Two years ago this thrilling footage was shared in the wake of expeditions to Antarctica, and a study reported that Fin whales of the Southern Hemisphere, which were almost brought to extinction by twentieth century industrial whaling, were found in high densities and returning to ancestral feeding grounds, indicating a recovering population. https://lnkd.in/gD27JJxd Now a new study indicates there may be over 50,000 fin whales in the Scotia Sea alone, an estimate which is more than three times higher than previously estimated for the entire Southern Ocean. https://lnkd.in/gmCiuiVj The recovery of a keystone species on this scale is a significant boost to the integrity and functioning of marine #ecosystems in the Southern Ocean. As the first study highlights, the return of these giants could restore #ecosystem functions crucial for atmospheric #carbon regulation in the world's most important ocean region for the uptake of anthropogenic CO2. #conservationsuccess #marineprotection #sdg14
