This book contributes to the current discussion on global environmental changes by discussing
modifications in marine ecosystems related to global climate changes. In marine ecosystems
rising atmospheric CO2 and climate changes are associated with shifts in temperature
circulation stratification nutrient input oxygen concentration and ocean acidification
which have significant biological effects on a regional and global scale.Knowing how these
changes affect the distribution and abundance of plankton in the ocean currents is crucial to
our understanding of how climate change impacts the marine environment.Ocean temperatures
weather and climatic changes greatly influence the amount and location of nutrients in the
water column. If temperatures and currents change the plankton production cycle may not
coincide with the reproduction cycle of fish.The above changes are closely related to the
changes in radiative forcing which initiate feedback mechanisms like changes in surface
temperature circulation and atmospheric chemistry.
