Phytoplankton community structure in relation to vertical stratification along a north‐south gradient in the Northeast Atlantic Ocean
Abstract Climate change is affecting the hydrodynamics of the world's oceans. How these changes will influence the productivity, distribution and abundance of phytoplankton communities is an urgent research question. Here we provide a unique high‐resolution mesoscale description of the phytopla...
