1. Physical Oceanography Analysis of Puerto Morelos Field Work
Seasonal and fortnightly variations in submarine groundwater discharge

2. 2. Seasonal and fortnightly variations in submarine groundwater discharge
Power spectra of water surface elevation and vertical velocities
Turbulent Kinetic Energy analysis to obtain dissipation rates
Seasonal comparison of wet vs. dry periods

3. Motivation! Why do we care?? SGD impacts our groundwater supplies!
(cue descriptive graphic)
Some culprits:
Sea Level Rise
Over pumping
Pollution
