Submesoscale feedback suppresses marine heatwaves.
Article in Science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Marine heatwaves (MHWs) are devastating extreme ocean temperature events whose frequency and severity have surged under global warming, threatening marine ecosystems and fisheries. Yet, the fundamental mechanisms that control their intensity and persistence remain incompletely understood. Here, using a submesoscale-permitting global model simulation validated by long-term observational and reanalysis data, this study reveals a previously overlooked submesoscale feedback that exerts a critical control on MHW severity. It is demonstrated that the submesoscale-induced vertical heat flux suppresses the intensity and persistence of atmosphere-driven MHWs in winter via a negative feedback mechanism. Enhanced air-sea net heat flux strengthens stratification and shoals the mixed layer, weakening submesoscale vertical heat transport by 19.4%, reducing MHW intensification by 18.1%, and accelerating decay by 21.7%. This missing regulatory mechanism indicates that models ignoring the submesoscale feedback likely overestimate MHW severity, with critical implications for future climate projections.
