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.

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
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.

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.

Marine heatwaves pose a serious threat to marine ecosystems that will become increasingly important with climate change. Here we show in the Southwest Pacific that dynamical forecasting systems are able to forecast long, large-scale marine heatwaves occurring in austral winter, but have less skill in predicting smaller, shorter events, and summer events. We discuss the implications for operational forecasts dedicated to help marine managers to prepare and mitigate some of their impacts.

Marine heatwaves—periods of unusually warm ocean temperatures—are becoming more frequent and intense with climate change. These events can harm marine ecosystems, especially in vulnerable regions like French Polynesia. Here, we used satellite sea surface temperature data and ocean reanalysis to characterize past events. We investigated their characteristics, variability linked to El Niño Southern Oscillation, and the physical mechanisms driving their onset and decay across the region.

Short summary
To detect past marine heatwaves events and analyse their characteristics, scientists use one of the available sea surface temperature products, relying on different data ingested and procedures. Here, we compare marine heatwaves statistics computed using six products in the tropical Pacific over 1993–2021. We highlight significant differences and provide uncertainties. Our results advocate for the use of multiple products in marine heatwaves studies to increase the robustness of the conclusions.

This paper characterizes historical (1981–2023) marine heatwaves in the tropical southwestern Pacific, where they pose a challenge for marine resource dependent Islands. Heatwaves are distinguished as a function of their spatial extent, signature at the coast, and seasonality, to allow a better understanding of their impacts on ecosystems. Marine heatwaves are getting longer and more frequent, with greater spatial extents. Our results aim to inform the Pacific Islands on their vulnerability.

Measuring oceanic vertical velocities accurately is a challenge in today’s physical oceanography. Our work shows intense wind-induced coastal events involving upward or downward water movements that have been detected using an acoustic current profiler. These data has also been validated with other in situ and satellite observations. A brand new method to identify and filter out biology-induced velocities is also presented, giving an interdisciplinary point of view of such coastal processes.

Due to ocean warming, coral reef ecosystems are strongly impacted by dystrophic events and corals experiencing increasing frequencies of bleaching events. In situ observation remains the best alternative for accurate characterization of trends and extremes in these shallow environments. This paper presents the coastal temperature dataset of the ReefTEMPS monitoring network, which spreads over multiple Pacific Island countries and territories (PICTs) in the western and central South Pacific.

The land-to-ocean flux of particulate organic carbon (POC) is difficult to measure, inhibiting accurate modeling of the global carbon cycle. Here, we quantify the POC flux between one of the largest rivers on Earth (Congo) and the ocean. POC in the form of vegetation and soil is transported by episodic submarine avalanches in a 1000 km long canyon at up to 5 km water depth. The POC flux induced by avalanches is at least 3 times greater than that induced by the background flow related to tides.

Extreme weather events can have a major impact on ocean physics and biogeochemistry, but their study is challenging. In May 2019, an intense storm occurred in the north-western Mediterranean Sea, during which in situ multi-platform measurements were performed. The results show a strong impact on the surface phytoplankton, highlighting the need for high-resolution measurements coupling physics and biology during these violent events that may become more common in the context of global change.

Cyclonic storm surges constitute a major threat to lives and properties along the vast coastline of the Bengal delta. From a combination of cyclone and storm surge modelling, we present a robust probabilistic estimate of the storm surge flooding hazard under the current climate. The estimated extreme water levels vary regionally, and the inland flooding is strongly controlled by the embankments. More than 1/10 of the coastal population is currently exposed to 50-year return period flooding.

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.
