🧊 Since 2020, the total ice mass in #Antarctica has stopped decreasing. How?

Researchers from the UG & KNMI found that a sharp increase in snowfall is mainly due to ‘atmospheric rivers’ transporting extra moist air to the ice sheet.🌨️

Analysis of a 16-meter sediment core from Lake Yoa in Chad reveals that the "African Humid Period" (14,800 to 5,500 years ago) was not a continuously wet era, but was instead abruptly interrupted by severe, decadal-scale droughts.

The 40,000-year obliquity cycle tied to Earth's axial tilt, which dictated the growth and decay of the Antarctic ice sheet 34 million years ago, directly drove marine biological productivity in the distant subtropical ocean.

'Dark oxygen' discovery on the seafloor is 'fundamentally at odds with thermodynamics' and should be retracted, experts say

In a recent opinion article, marine scientists and electrochemists listed a number of reasons why it's unlikely that metallic nodules on the deep seafloor could produce oxygen in total darkness.

The oceanic tidal pulse extends significantly deeper into terrestrial waterways than previously recognized, serving as a highly dynamic force that continuously alters the physical and biological landscapes of coastal rivers.

First Global Map Reveals the Deep Reach of Ocean Tides into Coastal Rivers

For centuries, the boundary between ocean and river has been conceptualized as a relatively static margin.

No wader boots and reasonable sweaters here, no – you can't be on a field trip without a pipe!

Established in 1903, #Bergen’s marine research courses were the world's first formal academic programs in fisheries science. The initiative brought together leading experts to bridge the gap between practical fishing and scientific research. These courses utilized data from North Atlantic expeditions to provide students with cutting-edge laboratory and field-based training. This innovative approach quickly transformed the Bergen Museum into a pioneering center for #Oceanography and #MarineBiology.

Over 140 foreign scientists and students was drawn to Bergen before 1913. By hosting these diverse researchers, the courses established a collaborative milieu that solidified Bergen's reputation as a global marine hub. The integration of private funding and museum resources proved that marine science was a vital pillar for the city's academic identity. Ultimately, these early courses laid the essential foundation for the world-class marine research environment that Bergen maintains today.
