Global Lake Status Data Base (GLSDB)Entry ID: GLSDB
Abstract: The Global Lake Status Data Base (GLSDB: Kohfeld and Harrison, 2000, Harrison
et al., 2003) is a long-standing international effort to compile the geomorphic
and biostratigraphic data for changes in lake status, in order to document
changes in regional water balance during the last 30,000 14C kyr. Developed
with data-model comparisons as a primary objective, the GLSDB ... contains data
both from closed-basin lakes in now-arid regions and from currently overflowing
lakes in temperate and wet tropical regions. The GLSDB contains continuous
records of lake status through time, so that site chronologies can be modifed
and data extracted for any time interval required. Here, we present the data
for the mid-Holocene (6000 yr B.P. on the radiocarbon time scale) and the last
glacial maximum defined as 18,000 yr B.P. on the radiocarbon time scale,
equivalent to 21,000 yr B.P. on the calendar time scale) derived from Kohfeld
and Harrison (2000) and including updates published in Yu et al. (2001) and
Harrison et al. (2003).
The current version of the GLSDB (Version 2) has records for 599 modern sites,
413 sites at 6000 yr B.P., and 103 sites at 18,000 yr B.P. Please note: the
data sets contain information about the quality of the dating control at each
time period (DC6 = dating control at 6000 yr B.P., DC18 = dating control at the
last glacial maximum) using the COHMAP dating control schemes, as described in
Yu and Harrison (1995). We stongly recommend that you only use sites with a
dating control <7 in making data-model comparisons at 6000 yr B.P. and <7 in
making data-model comparisons at 18,000 yr B.P. (as is done in the maps shown
above). Sites with no explicit dating control should be included. If you do
this, you should have 599 modern sites, 394 6000 yr B.P. sites, 70 18,000 yr

Use Constraints If you wish to use the global data set, you should cite Kohfeld and Harrison
(2000), Yu et al. (2001) and Harrison et al. (2003) as the sources of the
original data. If you wish to have lake status maps for other time periods in
the last 30,000 years, you should contact Sandy Harrison directly.
