During the Spring Bloom the Plankton?

Spring brings warmer temperatures and increased sunlight, creating a thermocline that traps nutrients at the ocean surface. This allows phytoplankton to absorb energy and take in the nutrients they need to photosynthesize and multiply. The warming of the surface layer keeps this water less dense, so it stays afloat.

What season does phytoplankton bloom?

The spring bloom is a strong increase in phytoplankton abundance (i.e. stock) that typically occurs in the early spring and lasts until late spring or early summer. This seasonal event is characteristic of temperate North Atlantic, sub-polar, and coastal waters.

What is a bloom of plankton?

A bloom takes place when a species of phytoplankton reproduces at a rapid rate, multiplying quickly in a short amount of time. Sometimes more than one species blooms at the same time. Phytoplankton are photosynthetic organisms that live suspended just beneath the water's surface.
