CALE is a multinational and multidisciplinary research program investigating the most important questions currently associated with understanding circum-Arctic lithosphere evolution. The project runs for 5 years (2011–2015).
Incorporating the most recent data sets available and integrating on-shore with off-shore geology, CALEwill test existing hypotheses, and confidently formulate new ones, related to understanding the evolution of Arctic lithosphere, such as:
• Where are the plate boundaries associated with the Amerasia Basin?
• How and when did the Canada Basin open?
• What was the pre-drift setting of the Chukchi Borderland?
• How and when did the major ridges in the Amerasia Basin form?
• Where are the Early Tertiary plate boundaries in the Arctic?
• Which tectonic processes formed the Laptev, East Siberian, and Chukchi sea shelves?
• Where are the continuations of pre-Eocene orogens in the Arctic?
• How do these crustal-scale discontinuities influence Arctic tectonic evolution?
• What is the nature, age, internal structure and stratigraphy of the main sedimentary basins?
• How has this tectonic evolution affected the sedimentation history of the Arctic basins?
