Its objective is to promotethe effective control of all sources of marinepollution and to take all practicable steps toprevent pollution of the sea by dumping ofwastes. Currently, 86 States are Parties to thisConvention.Robert G. Dean, Professor Emeritus in theCoastal and Oceanographic EngineeringProgram, civil and Coastal EngineeringDepartment, University of Florida, Gainesville,Florida, made his speech about “Sea LevelAcceleration: Based on Analysis of TideGauge Records” and surprisingly conclude thattheir analyses of long term U. S. gages show asmall negative acceleration during the 20 thcentury and Acceleration results from long termworldwide gages are consistent with findingsbased on U. S. gages. It is surprising that withmost of the anthropogenic effects occurring inthe 20 th century, there is not corresponding sea level acceleration and he mentioned that othereffects dominant over Green House Gas emissions and global Warming during the 20 thcentury.Prof. Yoshimi Goda, Professor Emeritus fromYokohama National University and ECOHCORPORATION, presented "CoastalProtection Planning against Sea Level Rise"and he wrapped up by mentioning that the sealevel rise is a slow but confirmed process andadaptation plan should be revised every ten (10)years. Protective facilities should be capable offuture improvement, so Dikes/seawalls need tobe heightened and reinforced as the design waterlevel and wave heights are raised.
