Abundance and physical controls of Mediterranean micro-estuaries
Estuaries, critical transitional zones between freshwater and marine environments, are frequently studied as larger systems, leaving smaller micro-estuaries comparatively understudied. This research defines and investigates the abundance of Mediterranean micro-estuaries—vital coastal features facing increasing anthropogenic and climate-driven pressures. Utilizing a decade of hydrographic data and GIS analysis across seven East Mediterranean sites, we identified 243 micro-estuary-like systems, many previously undocumented.
[OC] A short explainer on the North Atlantic warming hole: heat transport, freshening, stratification, and AMOC
The North Atlantic warming hole, a region of unusually cold sea surface temperatures south of Greenland, has garnered significant attention. This explainer video clarifies frequently misunderstood aspects of this phenomenon, distinguishing between sea-surface temperature and total ocean heat content, and addressing the role of freshening and stratification. It also cautions against generalizing localized subsurface warming and emphasizes that while the warming hole may reflect shifts in ocean heat transport, it doesn't inherently signal imminent AMOC collapse.
Non-tidal sheared turbulent mixing observed in the Halmahera sea
The Indonesian Throughflow (ITF) significantly influences Earth’s climate through turbulent mixing within Indonesian seas. Recent research, utilizing moored current meter data in the Halmahera Sea, reveals that non-tidal sheared turbulence, driven primarily by Internal Gravity Waves (IGWs), dominates below 500 meters – accounting for over 80% of vertical shear. While the Gregg-Henyey-Polzin (GHP) turbulence parameterization accurately models dissipation in the upper 300 meters, its performance degrades deeper, highlighting the need for refined models incorporating IGW characteristics.
Climate warming drives multidimensional reorganization of global zooplankton community structure and function: an updated review
Climate warming is fundamentally reshaping global zooplankton communities, impacting their structure and function through a complex interplay of environmental stressors—ocean warming, acidification, and intensified stratification, among others. This updated review synthesizes empirical evidence, highlighting how these drivers influence species distributions, body sizes, and ecosystem processes like carbon cycling and nutrient regeneration. Taxonomic and regional variability significantly affect these responses, demanding integrated approaches combining long-term observations and advanced modeling.
