Triggers for the spring phytoplankton bloom

Editor’s Highlight—

 

Within ocean sciences, there is currently considerable interest in mesoscale eddies and their impacts on biology. This paper makes a contribution to this scientific field by examining how mesoscale eddies affect the timing of the spring bloom of phytoplankton in the Japan Sea. By contrasting bloom events in cyclonic and anti-cyclonic eddies, the authors determine important processes needed for initiating blooms. The mechanisms are general and may apply to other regions of the world ocean.

Featured Special Collection

A Census of Atmospheric Variability from Seconds to Decades 

The atmosphere varies naturally on all length scales from millimeters to thousands of kilometers, and on all time scales from seconds to decades and longer.  This special collection of Geophysical Research Letters synthesizes and summarizes that variability through a phenomenological census.  The collection brings together some of the most influential and definitive papers to have been published in this journal in recent years.  The topics covered include turbulence on time scales of seconds and minutes, gravity waves on time scales of hours, weather systems on time scales of days, atmospheric blocking on time scales of weeks, the Madden–Julian Oscillation on time scales of months, the Quasi-Biennial Oscillation and El Niño–Southern Oscillation on time scales of years, and the North Atlantic, Arctic, Antarctic, Pacific Decadal, and Atlantic Multi-decadal Oscillations on time scales of decades.  The collection is accompanied by a Commentary article, which provides an authoritative, concise, and accessible point of reference for the most important modes of atmospheric variability.
