Our study focuses on the characteristics of MHWs in the Red Sea during the last 4 decades. Using satellite-derived sea surface temperatures (SSTs), we found a clear warming trend in the Red Sea since 1994, which has intensified significantly since 2016. This SST rise was associated with an increase in the frequency and days of MHWs. In addition, a correlation was found between the frequency of MHWs and some climate modes, which was more pronounced in some years of the study period.

This paper presents the results of the first scientific campaign of a new method to remotely sense the small-scale, fast-evolving dynamics that are vital to our understanding of coastal and shelf sea processes. This work represents the first demonstration of the simultaneous measurement of current and wind vectors from this novel method. Comparisons with other current measuring systems and models around the dynamic area of the Iroise Sea are presented and show excellent agreement.

This study advances the understanding of climate projection variability in the Nemunas River, Curonian Lagoon, and southeastern Baltic Sea continuum by analyzing a subset of climate models with a focus on a coupled ocean and drainage basin model. This study investigates the variability and trends in environmental parameters, such as water fluxes, timing, nutrient load, water temperature, ice cover, and saltwater intrusions in Representative Concentration Pathway 4.5 and 8.5 scenarios.

The biological carbon pump plays a key role in the climate system. Plankton absorb and transform CO₂ into organic carbon, forming particles that sink to the ocean floor. Sediment traps catch these particles and measure the carbon stored in the abyss. However, the particles' surface origin is unknown as ocean currents alter their paths. Here, we train an AI model to predict the origin of these particles. This new tool enables a better link between deep-ocean observations and satellite images.

Using a high-resolution model, we estimated the volume, freshwater, and heat transports along Indian coasts. Affected by coastal currents, transport along the eastern coast is highly seasonal, and the western coast is impacted by intraseasonal oscillations. Coastal currents and equatorial forcing determine the relation between NHT and net heat flux in dissipating heat in coastal waters. The north Indian Ocean functions as a heat source or sink based on seasonal flow of meridional heat transport.

This study examines the seasonal variability in internal tide sea surface height in a global model simulation. We also compare this with altimetry and the seasonal variability in the internal tide energy terms. Georges Bank and the Arabian Sea show the strongest seasonal variability. This study also reveals that sea surface height may not be the most accurate indicator of the true seasonal variability in the internal tides because it is modulated by the seasonal variability in stratification.

We used a simplified model to investigate how changes in abyssal stratification can impact the propagation of vortices in the ocean. Although abyssal stratification is typically considered stable, observations have shown that this is not always a good approximation. We found that changes in deep stratification can introduce variability into the patterns of the vortices. Despite the assumptions made in our model, our results are supported by seafloor observations in the Ionian Sea.
