Globally, seabirds remove a prey biomass equivalent to commercial fishery landings, suggesting likely competition for resources that will vary spatially and seasonally. Using extensive aerial surveys combined with species-specific energetic […]
Plasma waves in the magnetosphere scatter electrons, causing them to precipitate into Earth’s atmosphere, imparting their temporal characteristics to diffuse auroras. In a case study of conjugate radar and satellite […]
One-third of the world’s ocean surface is located in the Southern Ocean, south of 30°S, encircling the Antarctic continent south of 30°S. The ocean circulation in this vast region has […]
The diverse chapters in this book have each, and collectively, highlighted how Antarctica and the Southern Ocean are key features on Planet Earth, and how they exert a marked influence […]
This chapter examines the historical legacy of human activities in and around Antarctica and assesses pollutants from the mid-late 20th century onwards that will have lasting impacts, potentially thousands of […]
Awe-inspiring and culturally unique, Antarctica’s remoteness and extreme conditions have long challenged exploration and understanding. Its vast ice sheet conceals secrets of ancient landscapes and harbours clues to Earth’s past […]
This book presents a state-of-the-art overview of the role that Antarctica and the Southern Ocean play as integral parts of the Earth System. While often characterised as the last great […]
Sea salt aerosol (SSaer) significantly impacts aerosol-radiation and aerosol-cloud interactions, and sublimated blowing snow is hypothesized to be an important SSaer source in polar regions. Understanding blowing snow and other […]
The characteristics of very low frequency (VLF) radio wave propagation in the Earth-ionosphere waveguide are determined particularly through dawn and dusk using phase and amplitude measurements of man-made signals propagating […]
Weather prediction is critical for a range of human activities including transportation, agriculture and industry, as well as the safety of the general public. Machine learning is transforming numerical weather […]
The Tristan albatross Diomedea dabbenena is a Critically Endangered species that breeds exclusively on remote islands in the South Atlantic Ocean. Although the population continues to decline, regular on-the-ground monitoring […]
