04.06.2026 June 2026: FSLEs help in modelling marine floating debris accumulation

Prediction map of floating marine debris accumulation. Yellow and red areas are accumulation zones; red shows a probability of above 50%, yellow areas indicate less than 50% ; black lines are oceanic fronts (from [Le et al., 2026])

Altimetry-computed Finite size Lyapunov Exponents can be used with other data to predict areas where marine floating debris accumulate

01.06.2026 SWOT- guided sampling reveals distinct phytoplankton communities within a fine-scale front

The BioSWOT-Med Sampling Region. The black line indicates the ship’s track throughout the entire cruise. The cross-front transect (purple) was conducted with a specific angular delay to track the front’s spatial evolution. Three 24-hour Lagrangian drifting stations were performed in distinct water masses: the northern mass (A2, May 7, blue star/line), the frontal zone itself (F25, May 6, red star/line), and the southern mass (B2, May 5, green star/line). Background SWOT tracks display absolute dynamic topography (m), as indicated by the color bar. The inset in the bottom right shows a representative cytogram identifying the seven phytoplankton groups detected during the cruise, plotted by side scatter (SWS, 90° light scattering) versus red fluorescence (FLR).

13.05.2026 Swot reveals fine-scale eddies efficiency in modulating ocean interior turbulence

Swot captures small structures previously elusive to nadir altimetry. (a) Swot vorticity derived from the SSH using the geostrophic assumption between 20 and 24 August 2023. (b) Gridded nadir altimetry geostrophic vorticity on 22 August 2023. Note the different color scales. from [Rolland et al. 2026].

Swot reveals that fine-scale eddies are as efficient as larger and more energetic structures in modulating turbulence in the ocean interior[more]
