The mesopelagic layer of the oceans, also known as the Twilight Zone, extends between ~200 and 1000 m depth and is one of the vastest contiguous ecosystems on Earth. It plays a pivotal role in global biogeochemical cycles and climate, and hosts a massive biomass of zooplankton and small fish. However, scientific understanding and predictive capacity of biogeochemical...

During the last century, the North Atlantic sea surface temperature exhibited super imposed long-term warming trend and multidecadal fluctuations. This multidecadal variability is referred to as the Atlantic Multidecadal Variability (AMV). The AMV has been pointed as the source of marked climate anomalies and associated human impacts over many areas of the globe. This...
