  1. #Panama’s #ocean lifeline vanishes for the first time in 40yr
    For decades, the #GulfOfPanama has relied on strong seasonal winds to trigger #upwelling, bringing cool, nutrient-packed water to the surface. But in 2025, this dependable event didn’t happen. Researchers point to unusually weak winds as the likely culprit, reducing ocean productivity and warming coastal waters. The surprise disruption highlights how vulnerable these critical systems may be to #climatechange.

  3. Panama’s Missing Pacific Upwelling

    Strong seasonal winds blowing from the Atlantic typically push water away from Panama’s Pacific coast, allowing deeper, colder waters to rise up. This upwelling cools reefs and feeds phytoplankton blooms, both of which support the rich marine life found there. But in early 2025, the upwelling didn’t occur.

    Normally, coastal ocean temperatures drop to about 19 degrees Celsius during upwelling. Instead, temperatures only reached 23.3 degrees at their coolest. Wind seems to be the missing ingredient: winds from the Atlantic side were short-lived and 74% less frequent than in typical years.

    That lack of upwelling is expected to carry consequences to Panama’s economy. About 95% of the country’s fishing catch comes from the Pacific side, so any drop in fish populations will be felt. The open question remains: was the missing upwelling a singular extreme event or a harbinger of a new normal? (Image credit: R. Heuvel; research credit: A. O’Dea et al.; via Eos)

  5. Tausende tote Fische an den Stränden rund um Rostock - untersucht werden Fisch- und Wasserproben aus der betroffenen Region auch am Thünen-Institut für Ostseefischerei.
    Institutsleiter Christopher Zimmermann erklärt im Interview mit dem NDR, welche Ursache für die toten Tiere vermutet wird, was das Sterben für die Fischbestände bedeutet und ob eine Gefahr für Badende besteht.

  7. ‼️ Im Golf von Panama blieb 2025 erstmals seit Beginn der Aufzeichnungen das saisonale #Upwelling aus.

    Normalerweise fördern Küstenwinde von Januar bis April kaltes, nährstoffreiches Wasser an die Oberfläche.

    Ursache für das Ausbleiben war schwächere #Passatwind-Aktivität. #Satellitendaten zeigen deutlich erhöhte #Oberflächentemperaturen.

  9. CW: An Annual Blast of Pacific Cold Water Did Not Occur, Alarming Scientists


    Each year between January and April, a blob of cold water rises from the depths of the #GulfOfPanama to the surface, playing an essential role in supporting #marine life in the region. But this year, it never arrived.

    When the #tradeWinds reach the Gulf of Panama they push hot surface water away from the coast, which makes room for cold water to rise from the deep.

  18. Large-scale ocean circulation is critical to our planet’s health and climate. In this process, seawater near the poles cools and sinks into the deep ocean, carrying dissolved carbon and nutrients with it. Later, that cold water gets pushed back up to the surface elsewhere, where it warms, and the cycle repeats. Although the theory behind this circulation has been around for decades, it’s been difficult to observe the rise, or upwelling, of water from the depths. But a recent study used a fluorescent, non-toxic dye to measure upwelling directly.

    Researchers deployed 200 liters of dye just above the floor of a marine canyon near Ireland, then monitored the dye’s movement for several days at a depth of 2200. They found that turbulence along the slope of the canyon drove upwelling at speeds of about 100 meters per day, much faster than global rates. The authors suggest that this kind of topographically-enhanced upwelling could be a major factor in setting overall ocean circulation. (Image credit: visualization – NASA, ship – S.

  22. The Southern Ocean upwelling is a mecca for #whales and #tuna that’s worth celebrating and protecting theconversation.com/the-southe

    "The Great Southern Australian Coastal #Upwelling System is an upward current of water over vast distances along #Australia’s southern coast. It brings nutrients from deeper waters to the surface. This nutrient-rich water supports a rich #ecosystem that attracts iconic species like the southern #BluefinTuna and #BlueWhale"
