| Summary: | Large chlorophyll anomalies are observed after the 2011 Japanese tsunami
using the NASA MODIS instrument onboard the TERRA and AQUA satellites. These
anomalies are observed both along the eastern coast of Japan, where the
tsunami wave hit with maximum force, and in the deep water surrounding the
epicentral region. Although both satellites show agreeing spatio-temporal
patterns, larger anomalies are detected using the AQUA satellite. A temporal
analysis shows increased chlorophyll concentrations immediately after the
tsunami, and higher values are observed for nearly one month before reversing
to pre-tsunami levels. |
