The ocean beneath ice shelves plays a critical role in their evolution and stability. Xiahou et al., describe a 4.5-year record of ocean measurements beneath the central Ross Ice Shelf to evaluate how the cavity seawater changes over time 🌊

The deep parts of the Arctic's Canada and Makarov Basins are among the most isolated waters in the ocean. Pasqualini et al., use tracer measurements to suggest that the last major flushing of deep water happened about 450 years ago 🌊

Icebergs provide a source of fresh meltwater to the polar ocean. Understanding how and when icebergs decay is critical to understanding their role in the climate system. Mamer and Robel investigate the role of surface waves in melting icebergs 🌊

New paper out in @jgroceans.bsky.social.

Upper-ocean heat content in the Western Indian Ocean increases despite declining surface heat flux → driven by heat transport and convergence.

As the upper ocean warms, this might enhance stratification and suppress exchange between the near-surface and deeper ocean layers. Kawai et al., investigate subduction and obduction rates in the North Pacific and find both are increasing 🌊

Team work makes the dream work! We asked our cruise team and they agree - team work is essential for troubleshooting and creating a positive environment for all on board 🚢, laying the groundwork for forging lasting connections that last beyond the cruise! 🧪
