The causes of apparent sea level changes, or whether tectonic movements, were responsible for changing coastlines, have been points of debate ever since it was recognised that unexplained changes did occur. Today it is clear that changing climates, are the result of changing conditions at the polar caps. Long term variations of climate are slow, but predictable. Short term variations are sudden and unpredictable, and in turn have catastrophic effects. In particular the heat absorbing capacity of the ice caps [Albedo] when the ice becomes colored, can have a sudden erratic influence upon the immediate world climate, and on sea levels. .[ A hypothesis for the change of ocean levels depending on the albedo of the polar ice caps - M.R.Bloch - Palaeogeography, Palaeoclimatology, Palaeoecology ]

SEA LEVELS

When investigating the salt trade and coastal salt production it has become evident that flooding and at other times lowering of the sea level, made the filling of solar evaporation pans very difficult. This seems to have been due to erratic changes of sea levels particularly in the Mediterranean, where salt production had been relatively easy because of a very small and predictable tide level, during certain periods, and impossible at other times. The evidence that has accumulated has indicated flooding of salt fields on coasts according to a curve:-

    Eustatic changes in sea levels, have greatly affected salt production


    At the end of the last ice age, approximately 8000 BP, it is estimated, the sea level rose by more than 60 m. The eustatic changes of the oceans in prehistoric and historic times are recognised as erratic and steep. A hypothesis is proposed to explain these erratic changes with Albedo changes of the polar ice caps, caused in turn by erratic volcanic and terrestrial dust fall-out. Ash layers in the Antarctic ice cores are connected with historic dislocations of salt production on ocean coasts and of maritime civilisations. Albedo changes through the dusting of the ice caps are proposed to be the cause for the decline of glaciation periods generally. Such albedo changes are connected with volcanic activity on the one hand, and loess formation on the other, and caused in turn by the growth of the ice caps.

    CLIMATE and VOLCANIC OUTBREAKS

    The post glacial eustatic level changes of the oceans are explained through ALBEDO [Datasets] changes of the Antarctic ice cap. Erratic Albedo changes are caused mainly by fallout of volcanic dust. The history of erratic volcanic activity in pre-historic and historical times should be compared and correlated to the eustatic changes of the ocean levels


    RUAPEHU errupts again The latest news of the most dangerous of volcanoes to the civilised world. Ice CoresIce core evidencenow from many sources, confirms past, and future probability of catastrophic changes in the rise and fall of the world's sea levels. In the last 2000 years, major volcanic eruptions have indirectly shifted climates, and increased sea levels, specifically in the Mediterranean, causing havoc to Roman salt making.

    One of the most dangerous Volcanoes in the southern Hemisphere, with the potential of spreading its ash over the Antarctic, causing the ice cap to melt.

      Ash - most probably from volcanoes, coloured the Antractic, and changed its Albedo, The Ice cores today are the evidence and a warning of a future catastrophy. -. It almost certainly was a factor in a catastrophic rise of 72 m at the Dead Sea from 60 BC - 90 BC.

      Index of warnings and data If we are prepared to investigate the historical references of salt production, perhaps we could prepare for similar events in our own era.
