The study introduces an innovative method for estimating meridional heat transport (MHT) across latitudes. By combining diverse oceanographic approaches, including remote sensing (gravimetry, altimetry), in-situ observations, and advanced statistical modeling, the study bridges several domains of ocean science. It opens the door for things such as an improved estimation of ocean heat content, surface fluxes, sea level variability, currents and enhanced error characterization in satellite observations. The new method could serve as the foundation for alternative estimates of both MHT and the Atlantic Meriodional Circulation (AMOC) that do not depend on costly, geographically limited in-situ observing arrays, which is especially beneficial if it allows the AMOC to be observed across a range of latitudes.

The article provides critical observations relating to the Thwaites Eastern Ice Shelf and the modified Circumpolar Deep Water. The observed warming has important consequences for implied basal melting and can impact the stability of the ice shelf, with notable subsequent impacts, such as addition of mass into the ocean and thus implied sea level rise. The work calls for further efforts in constraining the uncertainties via a combination of observations, modelling and mechanistic understanding.

This study provides new insights into understanding the vertical structure of mesoscale eddies, furthering our knowledge of their role in ocean property transport

This article is an engaging analysis and contributes to the ongoing discussion on intrinsic sea level variability and presents a novel and valuable contribution to our understanding of intrinsic sea level variability along the U.S. East Coast

The reoxygenation of the traditional hypoxic deep water of Gulf of St. Lawrence is a novel topic; this has not been addressed in the past. If reoxygenation would be implemented, it would represent an encouraging effort in the midst of reports on the dire consequences of climate change and ocean deoxygenation.

This paper highlights the changes in ocean temperatures and currents that are likely to affect the Great Barrier Reef in coming decades - affecting an iconic and unique environment. It uses newly available high-resolution coupled climate model output to assess the ocean warming and analyses the causes and repercussions of such warming due to climate change.
