The Thematic Sessions are listed below and are followed by the General Sessions.

Evolution of the Arctic Ocean and plate tectonic models for its origin
Conveners Arne Døssing, Carmen Gaina, Kris Meisling & Elizabeth Miller
Despite recent years of intense data collection and interpretation, the geodynamic evolution of the Arctic Ocean remains poorly resolved and highly controversial. Although the history of the Cenozoic Eurasia Basin is fairly well-established, details about various stages in its evolution start to emerge only now. Moreover, models explaining the formation of the Amerasia Basin during the Cretaceous still lack consistency. We propose a multidisciplinary session on the geodynamic and geological evolution of the Arctic Ocean. In addition to establishing the variety of plate tectonic models currently proposed for the formation of the Amerasia Basin and the timing of its opening, we welcome regional-scale studies that focus on the formation and structure of High Arctic lithosphere, including the role of magmatic and tectonic events. The goals of this session are to work towards a mutual understanding of the “boundary conditions” that define the limitations of plate tectonic models of the Arctic region, measure our progress towards consensus for a particular model(s) and timing scenarios, while underscoring the remaining unknowns in this endeavour.

Circum-Arctic onshore/offshore geological sampling
Conveners Gordon Oakey & Christian Knudsen
Ongoing Arctic geoscientific expeditions often include programs to sample the seafloor via dredging or shallow rock drilling. Although total recovery is quite small compared to the vast area and geological complexity, these samples represent the only physical examples of the offshore geology and are invaluable for understanding the development and evolution of the Arctic Ocean. This session will highlight the analytical and scientific results from offshore rock samples as well as results from circum-Arctic onshore samples for comparative analogues. Featured topics may include petrology, age dating, zircon provenance, apatite thermochronology, micropaleontology, etc.

Arctic foreland fold-thrust belts and adjacent foreland basins
Conveners Thomas Moore & Karsten Piepjohn
Fold-and-thrust belts and the foreland basins that accompany them preserve extensive records of the structural deformation and the tectonic events by which they formed. Such belts are numerous in the Arctic, ranging in age from Precambrian to Neogene. This session invites contributions on the timing, deformational style, kinematics, structural evolution, basin analysis, provenance and paleogeography of the frontal parts of the orogenic belts and adjacent foreland basins in the Arctic and welcomes efforts to correlate the underlying tectonic events that caused them across the Arctic region.

Lower Mesozoic Paleogeography of Circum-Arctic basins
Conveners Edward Fleming
The Lower Mesozoic is a very important interval in terms of its economic potential since, according to the USGS, much of the yet-to-find hydrocarbon resources of the Arctic nations are estimated to reside within this interval. Consequently, the Lower Mesozoic has attracted significant attention in recent decades and our increased understanding of it allows us to correlate stratigraphy, provenance and paleogeography across geopolitical boundaries. Correlating strata and paleogeography has implications for how we understand basin development and the interconnected nature of basins that are at present separated by many hundreds of kilometres. Specifically, correlations between different Arctic basins are key to understanding the full impact of the Siberian Traps Magmatism, the northern extent of the Uralian orogen, and the enigmatic “Crockerland” terrane.

ICAM General Sessions

Stratigraphy & Biostratigraphy
Conveners Olga Bogolepova, Victoria Ershova, & Peep Männik
Stratigraphy and biostratigraphy are fundamental to understanding depositional systems and basin evolution in the Arctic. The age and correlation of sediment deposits and sedimentary rocks is essential for accurate paleogeographic reconstructions and constraining the timing of tectonic events such as uplift and subsidence. This session invites all contributions that increase our understanding of stratigraphy and biostratigraphy within the Arctic realm.

Volcanic provinces, Tectonics, & Terrane Correlation
Conveners Valery Vernikovsky & Frances Deegan
The High Arctic is one of the last frontiers of geological exploration on Earth. Fundamental questions remain about the nature of the basement rocks in the ocean basins, about the geology of the borderlands of the Arctic Sea, and about the correlation and plate tectonic evolution of geological terranes. This session invites contributions from the broad range of geological and geophysical research that explores linkages between magmatism, tectonics, and terrane correlation.

Marine Geology & Geophysics
Conveners Bernard Coakley & Matt O’Regan
This session welcomes contributions in marine geology and geophysics that facilitate understanding the geology and geological evolution of the Arctic from a marine perspective. Contributions using datasets generated in connection with the Law of the Sea (UNCLOS 76) are particularly welcome, as are those that address the extent of continental versus marine crust in the Arctic.

Lithosphere Dynamics and Seismology
Conveners Jan Inge Faleide & Randell Stephenson
This session welcomes contributions based on any of a variety of methods that illuminate our understanding of circum-Arctic lithosphere, especially its accretion, modification and deformation through time to explain its present structure. Contributions that integrate across regions, or that combine geophysical approaches with geochemistry and geology are particularly useful. Modelling studies based on observational constraints are also welcome.

Arctic Resources (mineral, metallogeny, and hydrocarbon)
Conveners Sergey Drachev & Erik Henriksen
The Arctic region hosts tremendous mineral reserves, the most notable being oil and gas accumulations, ore minerals, precious metals and diamonds. While the currently challenging economic framework has postponed the most costly projects, this is an opportune time to regroup and develop new approaches and strategies that can result in significant advances in future Arctic exploration. This session on Arctic mineral resources is designed to facilitate an overview of recent exploration trends and discoveries, and to gather industry, academia and government experts from as many Circum-Arctic countries as possible to provide insight into the future of Arctic exploration and subsoil resource management.

Climate and the Cryosphere
Conveners Martin Jakobsson & Christof Pearce
The present extent and dynamics of ice sheets, permafrost, and sea ice on the continental margins in the Arctic has been influenced by Earth’s warming climate over the last century. The historical evolution of the Arctic’s climate and cryosphere over a longer time period than instrumental records provide is archived in sedimentary records and preserved landforms on the continental margin and adjacent high seas. In this session we welcome presentations on the past, present and future evolution and dynamics of the Arctic’s cryosphere and climate. In the context of climate we also include ocean conditions. We welcome studies of instrumental records, geophysical mapping, geological archives and results from numerical modeling.
