Talos Dome Ice Coring Project (TALDICE)

The TALos Dome Ice CorE (TALDICE) is a European ice core research project (Italy, France, Germany, Switzerland, United Kingdom) aimed at retrieving an ice core reaching back through the previous two interglacials (about 250,000 years), from a peripheral dome of East Antarctica, and want to reconstruct a reliable chronology, thanks to the presence of numerous layers of volcanic dust given the proximity of several volcanoes.

Talos Dome is an ice dome (159°11'E - 72°49'S, 2316 m asl) on the edge of the East Plateau of Antarctica, about 290 km from the Southern Ocean, 250 km from the Ross Sea, 275 km from Mario Zucchelli Station, 550 km North of Taylor Dome , 1500 km NW of Simple Dome, and 1100 km East of Dome C.

The TALDICE project started in the field in November 2004 and ended on December 23, 2007, at the final depth of 1620.20 m.

Ice Thickness 1795 m

Mean annual temperature -41°C

Mean annual atmospheric air pressure 721±10 hPa

Purpose: The main science objectives of the TALDICE project are the following: Determine temporal/spatial patterns in environmental parameters that relate to the ocean surface conditions (e.g., sea ice, marine biological productivity, storm activity) in the Southern Ocean/Ross Sea region; Reconstruct the sequence of events (including forcings and responses) through the last two glacial-interglacial transitions across Antarctica at high resolution; Synchronise the TALDICE records using high-resolution measurements of CH4, CO2, volcanic and dust stratigraphies, and isotopic compositions of air components, as well as absolute dating of volcanic layers; Identify climate modes and teleconnection patterns under different climate boundary conditions (orbital forcing, greenhouse gas concentration, land ice masses); Compile high-sensitivity evidence of subdued rapid climate/environmental transitions throughout the Holocene; Reconstruct snow accumulation changes at inland and coastal sites and identify changes in ice volume and local ice sheet altitude, from the Last Glacial Maximum through the Holocene to the present.
