Our working
days on coastal Lake Hamana are now definitively over. The platform has been
relocated to the Fuji area, where coring operations on Lake Kawaguchi were started.
Unfortunately,
we did not succeed in retrieving all missing core sections on site 3 and site 4
of Lake Hamana, since very strong winds threw a spanner in the works and we
were not able to sail out during the last two days. Nevertheless, we now possess
sediment samples up to a depth of 9 m below the lake floor, from four different
locations along a N-S transect throughout the central basin. Such transect
allows us to map the extent and lateral variations of tsunami deposits, which
will be traced by executing a series of sedimentological, geophysical and
geochemical analyses.
But first… our
cores have to be shipped back to Belgium. This will be done at the end of
November, after the Fuji survey is finished as well.
