Acronyms used
GMSL
Global mean sea level rise
TG
Tide gauge
VLM
Vertical land movement

Graphing the GMSL over time (1993-2014)
Sea level rise is accelerating
Comparing the adjusted and unadjusted series
Adjusted series is accounting for vertical
land movement (more accurate)
This is because VLM can change the readings of the
TGs which can alter the data about sea level rise
Satellite altimeters
Provide most accurate measurements and
projections of sea level change
Sucessful missions
TOPEX/Poseidon
Jason-1
OSTM/Jason-2
Data collection
TGs are elminated from analysis if they...
Non linear VLM
Earthquake threshold
Red dots in Figure 1 show TGs that were
used in this analysis (bias drift estimation)
