Marine picophytoplankton contribute roughly 20% of global oceanic primary production, including thermally resilient taxa such as Synechococcus , which dominate warm oceans and are projected to benefit from future warming. Tropical populations exist near their upper thermal limits, making them highly vulnerable to further warming, a largely unexplored risk for Synechococcus . Here, we combine high‐frequency in situ observations...

Among the well-known greenhouse gases (GHGs), nitrous oxide (N2O) is the third most impactful, possessing a global warming potential approximately 300 times greater than that of carbon dioxide (CO2) over a century. The distribution of N2O in aquatic environments exhibits notable spatial and temporal variations, and emissions remain inadequately constrained and underrepresented in global N2O emission inventories, particularly f...

After the launch of the Surface Water and Ocean Topography (SWOT) satellite planned for 2022, the region around the Balearic Islands (western Mediterranean Sea) will be the target of several in situ sampling campaigns aimed at validating the first available tranche of SWOT data. In preparation for this validation, the PRE-SWOT cruise in 2018 was conceived to explore the three-dimensional (3D) circulation at scales of 20 km tha...
