Abstract
Sea surface salinity, sea surface temperature and oil spills in coastal zone observations
are significant geophysical parameters in the Earth’s weather and climate system.
These are critical for understanding dispersion and biogeochemical interaction between
marine and land ecosystems. Coastal habitats such as wetlands, mangroves, seagrass
beds, salt marshes, estuaries, coral reefs and sand beaches provide invaluable benefits
to marine life and humans. Natural calamities such as tropical cyclones, coastal
flooding and turbidity impact coastal ecosystems. Anthropogenic activities like
aquaculture, infrastructure development, tourism services and ship mooring severely
affect coastal habitats. The restoration and conservation of these coastal habitats
are essential to achieve sustainable coastal management to protect natural resources
and the global environment.
Traditional methods of sampling and monitoring the marine habitats have various
limitations as they are very costly and time-consuming as well as have less spatial
coverage making it impossible to investigate the whole ecosystem. With the advancement
of earth observation capabilities in recent decades, remote sensing technology has
expanded to include a wide range of issues including biophysical parameter inversion
and ecosystem process characterization. Remote sensing technology has been extensively
utilized to map the coastline and it has the potential to update maps continuously.
So, this study provides a comprehensive update on the remote sensing technologies
that have been providing immense services to monitor and analyze coastal habitat
changes.
