Cover Story: Climate fluctuations and landscape evolution, with their associated impacts on northern coastal ecosystems, likely influenced human populations of Nunatsiavut who have inhabited the region for nearly 7000 years. Results from Oakes Bay West Lake revealed gradual acidification since ca. 4900 cal. yr BP, which is coherent with terrestrial vegetation development and/or neoglacial cooling, interrupted by periods of milder climatic conditions that favoured large sediment inputs. These complementary results allowed for the development of a local palaeoenvironmental framework that contributes to a better understanding of how landscape evolution and climate have influenced human societies through site availability and proximity to marine resources, and how, in turn, their activities impacted their immediate environment. View this paper

Outboard Onset of Ross Orogen Magmatism and Subsequent Igneous and Metamorphic Cooling Linked to Slab Rollback during Late-Stage Gondwana Assembly

  • Timothy Paulsen,
  • John Encarnación,
  • Anne Grunow,
  • Jeffrey Benowitz,
  • Paul Layer,
  • Chad Deering and
  • Jakub Sliwinski

Changes in magmatism and sedimentation along the late Neoproterozoic-early Paleozoic Ross orogenic belt in Antarctica have been linked to the cessation of convergence along the Mozambique belt during the assembly of East-West Gondwana. However, these...

The Contributions of Marine Sediment Cores to Volcanic Hazard Assessments: Present Examples and Future Perspectives

  • Chris Satow,
  • Sebastian Watt,
  • Mike Cassidy,
  • David Pyle and
  • Yuqiao Natalie Deng

The rigorous assessment of volcanic hazards relies on setting contemporary monitoring observations within an accurate, longer-term geological context. Revealing that geological context requires the detailed fieldwork, mapping and laboratory analysis...

Examining the Hydro-Climatic Drivers of Lagoon Breaching and Healing in a Deltaic Barrier

  • Juan Felipe Gómez,
  • Eva Kwoll,
  • Ian J. Walker and
  • Andrés F. Orejarena

As sea-level rise (SLR) and human-made interventions affect coastal currents and sediment transport, coastal barriers have become more vulnerable to the effect of storms, hurricanes, and climate variability. The response of each barrier is unique and...

The First Rock Glacier Inventory for the Greater Caucasus

  • Levan G. Tielidze,
  • Alessandro Cicoira,
  • Gennady A. Nosenko and
  • Shaun R. Eaves

Rock glaciers are an integral part of the periglacial environment. At the regional scale in the Greater Caucasus, there have been no comprehensive systematic efforts to assess the distribution of rock glaciers, although some individual parts of range...
