Caption

Figure 6.9 The chronology of the sea-level over the past 18,000 years deduced from ¹⁴C dating of peat and the shells of shallow-water marine organisms. All locations are in shallow areas of the Earth's crust, where major earth movements have been negligible. Although there is a wide scatter in the data, the points define a trend for global sea-level change.

Description

This scatter graph plots sea-level depth over time using data from 6 regions.

The horizontal axis is at the top and is labeled "years before present". It is marked in years from 0 to 20,000 at intervals of 1000 years.

The vertical axis is labeled "depth below present sea-level (m)" and is marked in meters from 0 to 100, at intervals of 10 meters.

The 6 locations are represented by different small symbols given in a key.

solid triangle = Texas

cross = Holland

solid dot = East Argentina

square = South-west Louisiana

open dot = Florida

open triangle= Sri Lanka

The general trend is an increase in depth as the past time increases. The increase is small in the recent past, up to 7,000 years ago at a depth of just over 10 meters then it increases more sharply to the lowest point marked at just under 18,000 years and 90 meters. The earliest data, from about 12,000 years and earlier is from Texas.

The trend is quite clear, although the band is wide, there are no data points in other areas of the graph.

An example of the wide scatter is shown in the Texas data, there are three points at about 45 meters over a spread of about 3,500 years. There are also three points at 13,000 years, two are at 60 meters, the other is at 70 meters.
