ABSTRACT
The information obtained from the modern Earth-observing satellites, enables comprehensive studies of
seasonal dynamics of ecosystems in different regions of the World Ocean. The properties of physical
environment (sea surface temperature, measured by AVHRR radiometers; currents estimated from
altimetry data; wind and precipitation measured by meteorological satellites) combined with biological
data derived from ocean optics, reveal principle features of phytoplankton seasonal cycles in diverse
ocean environments. The peculiarities of these cycles depend on local bottom topography, hydrological
regime, wind forcing, etc; in coastal regions river discharge is of great importance. The examples of
different types of seasonal cycles of phytoplankton are presented, and the mechanisms influencing the
phytoplankton growth are discussed. The peculiar region is the Northwest Atlantic near Newfoundland
