Abstract

Following up our work reported in the year pilot study report (Mackay et al. 1993), a total of 31 surface sediment cores were collected from Lake Baikal in the summer of 1993, in accordance with the original project proposals. Of these only 22 are suitable for quality stratigraphic work at the ECRC. These cores were taken from selected sites along the length of the lake, but owing to problems with ship-time and equipment, the southern basin was not fully sampled at this time. Consequently, earlier this year in March, we undertook a further expedition to collect more cores from the southern basin. This involved working from the lake whilst frozen. and hence necessited new techniques: 1700 m 'Kevlar' rope was purchased and a new winch refurbished, the latter being funded by The Royal Society. A further 7 cores were collected, 6 of which are suitable for stratigraphic work. These cores will also be used to check core replicability. There now remains one area, approximately 5 km from the eastern shore of the southern basin, following a transect towards the middle of that basin, where we still need to collect several cores (ca. 3) and this will be done early next year in March 1995.
