GI3033 Environmental Geodesy Syllabus:
GI3033 Environmental Geodesy Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
To introduce concepts of the Earth system and its observation techniques.
To expose the observables of hydrological, oceanographic, cyrospheric and atmosphere.
UNIT I THE EARTH SYSTEM
Systems approach to studying Earth, climate and weather systems, mass distribution, transport and exchange in the Earth system, Impact of physical processes on the geometry and gravity of the Earth, loading theory and the sea level equation.
UNIT II OBSERVATION TECHNIQUES IN GEODESY
Geometric techniques – Total Stations, Strain meters, Tide Gauges, Global Navigation Satellite Systems, Satellite Laser Ranging, Very Long Baseline Interferometry, Satellite Altimetry (radar and laser), Interferometric SAR; Gravimetric techniques – absolute gravimetry, relative gravimetry, Satellite gravimetry – CHAMP, GRACE and GOCE.
UNIT III TIDES AND HYDROLOGICAL OBSERVABLES
Gravitational interaction of the Sun, Moon and the Earth, ocean tides, atmospheric tides, solid Earth tides, Doodson numbers, Water storage change, soil moisture, river runoff and lake levels, groundwater variability.
UNIT IV OCEANOGRAPHIC AND CRYOSPHERIC OBSERVABLES
Sea surface topography and the mean sea level, ocean currents, ocean mass redistribution, ocean bathymetry, Sea ice thickness observations, ice mass balance, glacier thickness and drift.
UNIT V ATMOSPHERIC AND SOLID EARTH OBSERVABLES
Total precipitable water, ionospheric total electron content, atmospheric circulation and mass redistribution, Elastic, viscoelastic and episodic deformation and gravity responses to geodynamic processes like plate tectonics, Earthquakes and volcanic activity. Tsunami early warning, atmospheric / ionospheric seismology.
TOTAL:45 PERIODS
