• The Climate History of the Eastern Mediterranean as Recorded in Mollusk Shells

      Kaufman, Aaron; Magaritz, Mordeckai (American Journal of Science, 1980-01-01)
      An 18O/16O versus 14C age curve was constructed for unrecrystallized Holocene marine shell samples from Israel that were shown to be homogeneous populations. The surprisingly large variation in the oxygen isotopic composition (1.2 per mil) between 2600 and 4000 years ago is most probably due to variations in the isotopic composition of the water. This implies that either the excess of evaporation over precipitation or the Nile river discharge must have varied significantly during the Holocene.
