The historically unprecedented threats to the marine environment posed by increasing
atmospheric carbon dioxide will probably require the use of unconventional, non-passive …

The urgent need for effective climate change mitigation has spurred the exploration of
various negative emission technologies (NETs). Here, we investigate recent advancements …

Since the early 1980s, episodes of coral reef bleaching and mortality, due primarily to
climate-induced ocean warming, have occurred almost annually in one or more of the …

Artificial upwelling, as a geoengineering tool, has received worldwide attention because it
may actualize ocean fertilization in a sustainable way, which could potentially alleviate the …

Abstract Nature-Based Solutions (NbS), a concept introduced in the late 2000s, has
developed rapidly during the last years and is now frequently appearing in a broad spectrum …

Air-lift pumps for artificial upwelling of ocean water are finding increasing use as marine
primary productivity could be enhanced by pumping nutrient-rich deep water to the surface …

The expected increase in global food demand, as a consequence of a rising and wealthier
world population, and an awareness of the limits and drawbacks of modern agriculture, has …

The oceans are the largest carbon pools on Earth, and play the role of a “buffer” in climate
change. Blue carbon, the carbon (mainly organic carbon) captured by marine ecosystems, is …

Ocean artificial upwelling has been suggested to boost primary production and increase
harvestable resources such as fish. Yet, for this ecosystem-based approach to work, an …

Artificial upwelling has been proposed as a means of enhancing oceanic CO2 sequestration
and/or raising fishery yields through an increase in primary production in unproductive parts …
