The context of the observed sea level evolution during the altimetry era (since 1993) is discussed with regards to the
past sea level variation in Church and White (2011) and Meyssignac and Cazenave (2012).
However, the
mean sea level variations inferred from the remnants of the Roman era suggest that a similar high rate of increase may have occurred more than 2,000 years ago.
The WASA group (1998) similarly investigated the storm related
sea level variations at gauge stations in the south - eastern part of the North Sea.
This section focuses on global and
regional sea level variations, over time spans ranging from the last decade to the past century; a brief discussion of sea level change in previous centuries is given in Section 5.5.2.4.
Zonal asymmetry in SAM - associated winds might have contributed to the asymmetry of
decadal sea level variations in the southern ocean during most of the twentieth century.
2500 years of
past sea level variations This week, a paper will appear in the Proceedings of the National Academy of Sciences (PNAS) with the first global statistical analysis of numerous individual studies of the history of sea level over the last 2500 years (Kopp et al. 2016 — I am one of the authors).
Figure 3: Global
mean sea level variations (light line) computed from the TOPEX / POSEIDON satellite altimeter data compared with the global averaged sea surface temperature variations (dark line) for 1993 to 1998.
The map of regional mean sea level trends provides an overview of variations in the rates of relative local mean sea level observed at long - term tide stations (based on a minimum of 30 years of data in order to account for long -
term sea level variations and reduce errors in computing sea level trends based on monthly mean sea level).
Part IV of the Climate Etc. series on sea level rise focuses on the satellite era (since 1993), including the recent causes
of sea level variations and arguments regarding the acceleration (or not) of recent sea level rise.
2500 years of past
sea level variations This week, a paper will appear in the Proceedings of the National Academy of Sciences (PNAS) with the first global statistical analysis of numerous individual studies of the history of sea level over the last 2500 years (Kopp et al. 2016 — I am one of the authors).
Historical and archaeological evidence (prior to the instrumental period) of
sea level variations is also discussed.
To establish scientific cooperation focusing on: (a) Monsoon and ocean variability, climate change and
sea level variations, (b) Marine ecosystem studies, including algae blooms and (c) Coastal zone management including impact on society.
