Summary: IPCC assessments are a trusted source of scientific evidence for climate negotiations, but the time gap between report cycles creates an information gap. To fill this gap, we compile monitoring datasets based on IPCC report methods to provide annually updated reliable global climate indicators.

Summary: This study reveals the dual cascade of submesoscale currents, including fronts and mixed-layer eddies, in a coarse-graining framework. The dual cascade is captured in a simple mathematical form by writing the cross-scale energy flux in the local principal strain coordinate system. The results show that the forward energy flux at fronts is primarily driven by frontogenesis, while the rotational components are responsible for the inverse cascade.

Summary: Submesoscale baroclinic instabilities have been found to restratify the surface mixed layer and energize submesoscale turbulence in the upper ocean. This study investigates their impact on the large-scale circulation and stratification of the upper thermocline in the North Atlantic Subtropical Mode Water region. Numerical simulations at varying horizontal grid spacings reveal that an 8-km grid spacing is sufficient to capture the bulk impact of mixed layer instabilities on upper-ocean stratification through enhanced vertical buoyancy flux.

Summary: The modulation of leaf energy budget components to maintain optimal temperature is important for plant survival, especially under drying and warming climates. In a study on a semi-arid pine forest, it was found that leaf cooling in droughted trees relied exclusively on sensible energy flux, while in non-droughted trees, both sensible and latent energy fluxes contributed equally. This shift was due to a reduction in leaf aerodynamic resistance. This capacity for a shift in energy flux without increasing leaf temperature is critical for the resilience and productivity of this Mediterranean tree species under drying conditions.

Summary: Sea-level measurements from radar satellite altimetry have achieved a high level of accuracy and precision, allowing detection of global mean sea-level rise and attribution to greenhouse gas emissions. However, recent research suggests that there is still room for improvement in satellite altimetry performance. Reduced uncertainties would enable regional detection and attribution of sea-level change and improve estimates of ocean heat uptake.

Summary: Recent studies have shown that the intensification of Western boundary currents (WBCs) has led to nonuniform warming of shelf waters, with waters poleward of 32 degrees S warming more than twice as fast as those equatorward of 32 degrees S. The increase in lateral heat advection poleward of the WBC separation is the main driver of this phenomenon, with far-reaching biological implications.

Summary: This study examined the long-term trend and interannual variation of ocean heat content in the Bohai Sea, Yellow Sea, and East China Sea. The results showed an uneven spatial distribution of heat content in these regions, with a considerable amount stored on the outer shelf. Heat transport was mainly influenced by the Taiwan Strait, and the rapid warming on the outer shelf was associated with an increased heat transport located between northeast Taiwan and southwest Kyushu.

Summary: Results from a new, global, high-resolution earth system simulation show that recurring intermittent wind events in the Gulf Stream region induce strong latent heat bursts above warm Sea Surface Temperature anomalies, associated with small-scale SST fronts. This study highlights the importance of high-resolution modeling for understanding small-scale air-sea interaction phenomena.

Summary: Oceanic fronts with small lateral scales contribute significantly to vertical heat fluxes in the global ocean. Short-term frontal dynamics, which were previously obscured by energetic internal gravity waves, can now be recovered and accurately estimated by separating internal gravity waves and frontal dynamics.

Summary: We propose improvements to the modeling of the vertical wavenumber spectrum of internal gravity waves in regional ocean simulations. Our study focuses on the sensitivity of the model to mixing parameters and compares the results to observations. The findings suggest that improving the mixing parameters can enhance the representation of internal wave dynamics.

Summary: An unconstrained global ocean simulation in 2020 confirms previous observations of diurnal internal tides by acoustic tomography in the Western North Atlantic. The simulation accurately reproduces the characteristics of K1 and O1 internal-tide standing waves, but shows deviations from observations in terms of barotropic and internal tides. The tomographic data provide a benchmark for improving the representation of tides, internal tides, and dissipation in models.

Summary: Magnetic resonance imaging (MRI) contrast agents, such as Magnevist (Gd-DTPA), have limited blood circulation time due to rapid clearance by the kidney, which hinders the improvement of contrast between tumors and normal tissue. To address this issue, a novel MRI contrast agent using deformable mesoporous organosilica nanoparticles (D-MON) incorporating Gd-DTPA is fabricated. In vivo distribution studies show that the D-MON-based contrast agent can prolong blood circulation time and achieve high-contrast imaging in tumor tissue, surpassing the performance of the clinical contrast agent Gd-DTPA.

Summary: Arctic warming changes the fluxes of nutrients and organic matter from land to sea, affecting air-sea carbon exchange. Using a biogeochemical model, this study examines the role of Mackenzie River discharge in modulating air-sea CO2 fluxes in the southeastern Beaufort Sea from 2000 to 2019. The discharge of six chemical constituents leads to a net CO2 outgassing of 0.13 TgC yr(-1) and a decrease in the coastal carbon sink due to riverine dissolved organic and inorganic carbon. The results indicate that the Mackenzie River influences the capacity of the southeastern Beaufort Sea to act as a sink or source of atmospheric CO2. Accurate representation of land-to-sea biogeochemical coupling is crucial for understanding the Arctic coastal ocean response to the rapidly changing environment.

Summary: In order to improve the seismic performance of precast reinforced concrete structures, a superimposed slab shear wall with innovative construction details was proposed. Five innovative superimposed slab shear walls and one cast-in-place concrete shear wall were designed and tested, considering the effect of axial compression. The results showed that the innovative superimposed slab shear walls had a higher strength capacity and lower lateral-resistant stiffness than the cast-in-place concrete shear wall. The peak strength capacity of the superimposed slab shear wall increased obviously with the enlargement in the axial compression ratio, but degraded rapidly after the peak load. This investigation provides valuable data for future structural seismic performance evaluations and applications of precast superimposed slab shear wall structures.

Summary: In recent decades, changes in sea-ice seasonality in the Arctic Ocean (AO) have had significant impacts on the phenology of phytoplankton blooms. Early sea-ice melt triggers earlier blooms, while delayed formation of sea ice leads to second fall blooms. These changes could have important consequences for Arctic marine ecosystems in a warmer and changing climate.

Summary: The kinetic energy transfer between the atmosphere and oceans, known as wind work, plays a significant role in ocean dynamics. Recent numerical estimates have shown a nearly fivefold increase in global wind work amplitude compared to those reported a decade ago due to the inclusion of a broader range of spatial and temporal scales. However, existing satellite observations do not fully capture this range. The ODYSEA satellite mission, which utilizes a wide-swath measurement approach, performs well in estimating wind work globally, except at latitudes north of 40 degrees N during summer.

Summary: Near Inertial Oscillations (NIOs) are ocean oscillations forced by intermittent winds, most active at mid-latitudes. This study assesses the potential of a new satellite mission concept, OSYSEA, to recover wind-forced NIOs from co-located winds and currents. Results show that NIOs can be accurately recovered using the ODYSEA spatial and temporal resolution.
