Hr. Oliver et al., TIGGER: NERC-stimulated research into the geological perspective of terrestrial global environmental research, J GEOL SOC, 156, 1999, pp. 341-344
TIGGER was devised to study the geological factors relevant to the NERC TIG
ER programme (Terrestrial Initiative in Global Environmental Research). The
geological initiative concerned itself with the collection of high resolut
ion data to solve issues of global environmental change at different timesc
ales. All of the topics concerned are critical to natural climatic changes
since the Last Interfacial (c. 125 ka sp) and to the methodology of investi
gating these changes. TIGGER I, the SAHEL project. seeks to understand grou
ndwater discharge and recharge since the LGM (Last Glacial Maximum) and the
aeolian dune and lake changes since the Lateglacial in northeast Nigeria,
an area highly sensitive to drought. TIGGER IIa is concerned with proxy rec
ords of climate change over the last two millennia and their application at
a time of relatively low: magnitude climate variation but characterized by
high-resolution data sources. TIGGER IIb has investigated the way that ter
restrial ecosystems have adjusted to variations in climate, carbon dioxide
and surface chemistry over the period 15-11.5 cal ka BF and TIGGER IIc has
attempted to reconstruct longitudinal palaeoenvironmental gradients across
southern Europe during the Last Interglacial/Glacial transition based on mu
ltiproxy studies from across the region, two of which are recorded here. on
e from Kopias in Greece and one from northeast Mallorca.
