Marine transgression and regression, i.c. movements of the sea relative to the land, occurred in south‐western Scotland during the Holocene epoch. Wigtown Bay may have been more extensive than now, and the (now abandoned) Lochar Gulf may have been in existence at the beginning of the Epoch. Holocene marine transgression in S. Ayrshire began after 8400 B.P. Commencement of marine transgression from place to place along the northern shore of the Solway Firth was diachronous: between 9400 and 7200 B.P. Culmination also was diachionous; the Lochar Gulf was abandoned by the sea by 6600 B.P., but transgression continued in the eastern Solway Firth until about 5600 B.P., and near the head of Wigtown Bay until 5000 B.P. or later. A pause in regression of the sea from its maximum occurred about 2000 B.P. Comparison of curves for relative movements of sea level suggests that land uplift in S.W. Scotland between 9200 and 6000 B.P. was rapid compared with contemporaneous land uplift in N.W. England, Sweden, and the Netherlands.
