Holocene sedimentation in the Soline Channel (Mljet Lakes, Adriatic Sea)

A 103 cm long core from the Soline Channel (Mljet Island, Adriatic Sea), which is at present a surface connection between the peculiar marine Mljet Lakes and the open sea, indicates substantial changes of the sedimentary environment in the Holocene. In the layer dated to 4, 600 B.P., 25-30 cm below the bottom (which is at 2.8 m depth), freshwater algae represented by species of Chara/Nitella were found along with the gastropod Limnea stagnalis. This dominantly brackish sediment extends from 10 to 60 cm below the bottom. Above that interval marine sediment was found and below it quartz dominated subareal or freshwater sediment. This indicates that the surface marine connection between Mljet Lakes and the sea was established after deposition of freshwater/brackish sediments i.e. not earlier than ca. 4 kyr B.P.
