Short summary
Oceanic eddies are giant swirling currents that help transport heat, nutrients, and pollutants across the ocean. However, their life cycle has never been observed in detail. Using new satellite data, we tracked an intense eddy in the Gulf of Mexico, describing its life cycle from birth during a 6-month period. Our observations reveal small-scale turbulence surrounding it and interactions with other structures that shape its evolution, validating decades of numerical studies.

The ocean around Iceland is a key region for water mass transformation that drives global ocean circulation. We use 29 years of hydrographic data to examine the spatial and temporal variability of mixed layer depth and stratification, identifying three distinct regions: South, North, and Northeast. We present a comprehensive view of seasonal to multi-decadal variability in upper ocean structure and its link to a changing North Atlantic under global warming.

Short summary
The surface ocean is turbulent from several hundred to a few kilometres. The more the current field is turbulent, the more traveling waves over the underlying current that are scattered. In this paper we focus on an isolated eddy where spontaneous instabilities have occurred, resulting in the emergence of smaller structures. Thanks to the wave scattering we have been able to retrieve the underlying surface current gradients normally not retrievable with traditional current measurements.

The Atlantic ocean circulation that helps regulate climate is expected to weaken this century. Long-term measurements in the subtropics now show signs of weakening, but northern data are shorter and more variable. By combining several observing systems, we reconstructed northern circulation since 2004 and found strong ups and downs, but no clear long-term weakening so far.

Short summary
We found extreme drops in oxygen levels in the tropical Atlantic linked to surprisingly long-lived, small subsurface eddies. These eddies are hidden beneath the surface (undetectable by satellites) and are unusually stable, even in the highly dynamic ocean near the equator. Using long-term measurements and computer models, we show that these features can strongly influence oxygen supply and potentially impact marine ecosystems.

Short summary
Temporal variability of the semidiurnal internal tide around New Caledonia is investigated using regional modeling. An important contribution to temporal variability not linked to the spring–neap tide cycle is due to the presence of mesoscale eddies both at the generation sites and in the propagation direction. The incoherent tide has a widespread signature in sea surface height (SSH), challenging the SSH observability of mesoscale to submesoscale dynamics.

Short summary
A unique dataset of glider observations reveals tidal beams south of New Caledonia – an internal-tide-generation hot spot in the southwestern tropical Pacific. Observations are in good agreement with numerical modeling output, highlighting the glider's capability to infer internal tides while assessing the model's realism of internal-tide dynamics. Discrepancies are in large part linked to eddy–internal-tide interactions. A methodology is proposed to deduce the internal-tide surface signature.

Short summary
New Caledonia is a hot spot of internal-tide generation due to complex bathymetry. Regional modeling quantifies the coherent internal tide and shows that most energy is converted in shallow waters and on very steep slopes. The region is a challenge for observability of balanced dynamics due to strong internal-tide sea surface height (SSH) signatures at similar wavelengths. Correcting the SSH for the coherent internal tide may increase the observability of balanced motion to < 100 km.

Short summary
Eddies are ubiquitous in the ocean and alter physical, chemical, and biological processes. However, how they affect organic carbon production and consumption is largely unknown. Here we show how an eddy triggers a cascade effect on biomass production and metabolic activities of phyto- and bacterioplankton. Our results may contribute to the improvement of biogeochemical models used to estimate carbon fluxes in the ocean.

Short summary
The EUREC4A field campaign, designed to test hypothesized mechanisms by which clouds respond to warming and benchmark next-generation Earth-system models, is presented. EUREC4A comprised roughly 5 weeks of measurements in the downstream winter trades of the North Atlantic – eastward and southeastward of Barbados. It was the first campaign that attempted to characterize the full range of processes and scales influencing trade wind clouds.

Editorial statement
The Surface Water and Ocean Topography (SWOT) wideswath altimeter is providing unprecedented observations of the ocean surface, enabling characterisation of mesoscale eddies at high latitudes with a resolution fine enough to capture the relevant spatial scales. Eddies are smaller in high latitudes due to the change in the Coriolis parameter. The eddies in these latitudes are, however, important influencing deep-water formation, carbon uptake, and sea-ice melt. The paper shows that the new SWOT satellite enables robust, quantitative eddy detection in polar and subpolar oceans, opening the door to global eddy climatologies in areas previously inaccessible.

Short summary
We use new observations from the Surface Water and Ocean Topography Mission (SWOT) satellite to reveal the structure of ocean eddies in the Labrador Sea at unprecedented resolution. By comparison with ship-based measurements, we show that SWOT reliably detects these features even at high latitudes, where conventional altimetry is limited. Our results provide the first detailed view of mesoscale eddies in the Labrador Sea and highlight SWOT's potential in polar regions.
