Lessons learned from the “spot the alien” citizen science campaign (2022–2025) in Maltese waters and the second record of Cephalopholis hemistiktos in the Mediterranean
Citizen science offers a validated and increasingly crucial approach to monitoring marine ecosystems. This study evaluates the “Spot the Alien” campaign (2022–2025) conducted in Maltese waters, yielding 441 expert-validated records of non-indigenous, range-expanding, and cryptogenic species. Results demonstrate increased reporting effort and species richness, with notable seasonal and habitat-specific patterns. Significantly, the campaign documented the second Mediterranean record of *Cephalopholis hemistiktos*.
Assessing Mediterranean Sea temperature and salinity trends using Argo float data and reanalysis products between 2012 and 2025
A recent study rigorously assesses Mediterranean Sea temperature and salinity trends from 2012 to 2025, leveraging data from Argo floats and reanalysis products across three key basins. Findings reveal consistent warming, particularly in the Western Mediterranean and Ionian Sea, alongside salinity fluctuations influenced by North Atlantic freshening. Notably, subsurface salinification is also observed. While discrepancies exist due to data density, both datasets confirm ongoing warming and salinification, underscoring the impact of climate change.
First expedition Jaywun research vessel: assessment of microplastics from international waters, Spain to Abu Dhabi, U.A.E
The inaugural Jaywun research vessel expedition has yielded a transboundary assessment of microplastic (MP) pollution across critical international shipping corridors, from Spain to Abu Dhabi. Analyzing 100 surface-water samples collected across six regions—including the Mediterranean Sea, Red Sea, and Arabian Gulf—the study revealed MP concentrations ranging from 4 to 290 particles per liter. Notably, the Arabian Sea exhibited the highest mean concentrations, with polyester and polyethylene terephthalate dominating detected polymers.
