Short summary
Distributed optical fibre sensing (DOFS) is a technology that enables continuous, real-time measurements of environmental parameters along a fibre optic cable. Here, we review the recently emerged applications of DOFS in physical oceanography, and offer a perspective on the technology’s potential for future growth in the field.

Short summary
The Rockall Trough carries key ocean currents that affect Europe’s climate and seas. Researchers combined data from underwater sensors and robotic gliders to track water, heat, and freshwater flow from 2014 to 2022. They created a new method to merge this data, producing the first long-term record of one important current. This improves ocean monitoring and helps us better understand climate-related changes.

Short summary
Thwaites Glacier is retreating due to warm ocean water melting it from below, but its thick ice shelf makes this heat hard to monitor. Using hot water drilling, we placed sensors beneath the floating ice, revealing how surface freezing in Pine Island Bay influences heat at depth. Alongside gradual warming, we found bursts of heat that could speed up melting at the grounding zone, which may become more common as sea ice declines.

Short summary
We created the first standardised dataset of in-situ ocean measurements time series from around Antarctica collected since 1970s. This includes temperature, salinity, pressure, and currents recorded by instruments deployed in icy, challenging conditions. Our analysis highlights the dominance of tidal currents and separates these from other patterns to study regional energy distribution. This unique dataset offers a foundation for future research on Antarctic ocean dynamics and ice interactions.

Short summary
A novel seasonal three-dimensional high-resolution hydrographic gridded data set for the northern Antarctic Peninsula (NAP) based on measurements obtained from 1990–2019 by the ship-based Argo profilers and tagged marine mammals is presented. The main oceanographic features of the NAP are well represented, with the final product having many advantages compared to low-resolution climatologies. In addition, new information on the regional water mass pathways and their characteristics is unveiled.
