Abstract

This project addresses how marine phytoplankton — microscopic algae that fuel ocean food webs and contribute to global nutrient cycling — respond to differences in resource availability across the ocean. Nutrient supply in surface waters plays a central role in determining phytoplankton growth and overall ocean productivity. However, the ocean harbors a wide variety of phytoplankton species, and their varied…
