[narrator] By analyzing
the isotopic composition and thickness of
these growth rings, scientists can determine how much rain fell
during that time period. A large ring, for example, would indicate a period
of high precipitation. In this way, teams across the
Eastern Mediterranean, have managed to put together
a 150,000 year record of rainfall. And the results
are illuminating. And the results
are illuminating. Those isotopes show
that in that period between the late Bronze Age and the beginning
the of Iron Age, there was no growth
in the stalagmite. From that we can understand, this period was
a drought period

[narrator] By analyzing
the isotopic composition
00:00:03.534 --> 00:00:05.733
and thickness of
these growth rings,
00:00:06.002 --> 00:00:07.534
scientists can determine
00:00:07.534 --> 00:00:10.567
how much rain fell
during that time period.
00:00:11.301 --> 00:00:13.001
A large ring, for example,
00:00:13.001 --> 00:00:16.267
would indicate a period
of high precipitation.
00:00:17.534 --> 00:00:18.467
In this way,
00:00:18.467 --> 00:00:21.134
teams across the
Eastern Mediterranean,
00:00:21.134 --> 00:00:27.000
have managed to put together
a 150,000 year record of rainfall.
00:00:27.000 --> 00:00:28.347
And the results
are illuminating.
00:00:28.347 --> 00:00:30.002
And the results
are illuminating.
00:00:30.002 --> 00:00:32.767
Those isotopes show
that in that period
00:00:32.767 --> 00:00:34.534
between the late Bronze Age
00:00:34.534 --> 00:00:36.534
and the beginning
the of Iron Age,
00:00:36.534 --> 00:00:38.567
there was no growth
in the stalagmite.
00:00:39.002 --> 00:00:41.002
From that we can understand,
00:00:41.002 --> 00:00:43.267
this period was
a drought period.
