The detection of candidate kelp-associated RDOC signals throughout the global ocean provides molecular-level evidence of the long-distance export of macroalgae-derived RDOC to the pelagic and deep ocean, highlighting a major, previously unrecognized pathway of long-term storage of macroalgae-derived DOC in global oceans, although the precise fraction exported to the deep ocean remains to be quantified.

Revista con revisión por paresUso en el mundo realAn eastward-propagating coupled mode amplifying the early growth of extreme El Niño events
Here, by analyzing the 1982/1983, 1997/1998, and 2015/2016 events together with a large ensemble of climate model simulations, we identify an unusually early and reproducible ocean-atmosphere precursor to extreme El Niño: a slow, eastward-propagating coupled mode that develops in the western-central equatorial Pacific during boreal winter and spring.

We find that although the historical assessment reveals an improvement in the global average BWI score from 2000 to 2021, future projections under high-emission climate scenarios (SSP5-8.5) indicate disproportionate losses across 143 countries.

Revista con revisión por paresUso en el mundo realFácil de leerCoupled increases in pelagic fish productivity and export productivity during the Paleocene-Eocene Thermal Maximum
We find a widespread increase in pelagic fish productivity, particularly in the Pacific and North Atlantic, that closely tracks export productivity in trend and spatial pattern, suggesting this increase was fueled by enhanced carbon export from the surface ocean.
Revista con revisión por paresHypoxia and acidification antagonistically suppress nitrification but enhance its N 2 O production in coastal waters
Here, we demonstrate that along the estuarine-coastal continuum, the co-occurrence of hypoxia and acidification suppresses nitrification rates but stimulates nitrification-derived N 2 O emissions—although their combined effect is lesser than the sum of their individual effects.

Revista con revisión por paresUso en el mundo realThe impact of financing cost differences on global energy and industry decarbonization
Compared with assuming a uniform low-risk CoC, accounting for developing countries’ investment risks increases global mitigation costs through 2100 for staying well below +2 °C by around 9% and shifts cost-effective mitigation efforts to lower-risk regions.

Our case study contrasted Sweden’s fragmented rivers with modelled free-flowing conditions and found that the observed fragmented rivers may favour specific fish life history strategies, that ecosystem functioning has shifted towards more baseflow-dominated flow compared with free-flowing rivers and that restoring all rivers to free-flowing conditions would result in more similar rivers nationally.
