Biophysical Interactions Stimulate the Spring Phytoplankton Bloom in the North Pacific Subtropical Recirculation Gyre Open
Although previous studies have found that restratification caused by mixed layer eddies induces early spring blooms near fronts under the nutrient‐replete conditions of the subarctic ocean, the genesis of the spring bloom in nutrient‐deple…

Lateral nitrogen input during summer in Sagami Sea with a deep trough enhances particulate organic carbon export Open
In deep bays linked to the open ocean, efficient carbon sequestration occurs through the sinking of particulate organic matter produced in the euphotic zone. Nutrient conditions in the surface layer of temperate bays, which are crucial for…

Archaean green-light environments drove the evolution of cyanobacteria’s light-harvesting system Open
Cyanobacteria induced the great oxidation event around 2.4 billion years ago, probably triggering the rise in aerobic biodiversity. While chlorophylls are universal pigments used by all phototrophic organisms, cyanobacteria use additional …

Nitrogen Isotopes of Sinking Particles Reveal the Seasonal Transition of the Nitrogen Source for Phytoplankton Open
In the high‐productivity subarctic ocean, phytoplankton growth is assumed to rely mainly on nitrate, based on snapshot observations conducted in spring or summer. However, the year‐round utilization of nitrate and ammonium by phytoplankton…
