Rubidium-strontium age studies and geochemistry of acid veins in the Freetown complex, Sierra Leone
Read more of: Rubidium-strontium age studies and geochemistry of acid veins in the Freetown complex, Sierra LeoneThe stratigraphical limits on the age of the Freetown intrusion, Sierra Leone, are very wide, yet the intrusion has not previously been accurately dated by isotopic methods, despite a number […]

sFDvent: a global functional trait database for deep-sea hydrothermal vent fauna
Read more of: sFDvent: a global functional trait database for deep-sea hydrothermal vent faunaTraits are increasingly being used to quantify global biodiversity patterns, with trait databases growing in size and number, across diverse taxa. Despite growing interest in a trait‐based approach to the […]

Assessing the recovery of an Antarctic predator from historical exploitation
Read more of: Assessing the recovery of an Antarctic predator from historical exploitationThe recovery of whale populations from centuries of exploitation will have important management and ecological implications due to greater exposure to anthropogenic activities and increasing prey consumption. Here, a Bayesian […]

Mapping crustal shear wave velocity structure and radial anisotropy beneath West Antarctica using seismic ambient noise
Read more of: Mapping crustal shear wave velocity structure and radial anisotropy beneath West Antarctica using seismic ambient noiseUsing 8‐25s period Rayleigh and Love wave phase velocity dispersion data extracted from seismic ambient noise, we (i) model the 3D shear wave velocity structure of the West Antarctic crust […]

The importance of the Antarctic in atmospheric sciences
Read more of: The importance of the Antarctic in atmospheric sciencesA prime objective of atmospheric science research in Antarctica is to use the special conditions found there to throw new light on global problems and, in particular, to test theories […]

Ozone measurements at British Antarctic Survey stations
Read more of: Ozone measurements at British Antarctic Survey stationsOzone measurements have been made regularly at Argentine Islands and Halley Bay since 1957. A recent critical review of the data revealed inconsistencies in the extraterrestrial constants adopted for the […]

Radio wave doppler studies of the Antarctic ionosphere
Read more of: Radio wave doppler studies of the Antarctic ionosphereThe occurence of propagating wave-like disturbances in the atmosphere at ionospheric heights is well documented, but their causes and role in the energy balance of the atmosphere is poorly understood. […]

Very low frequency electromagnetic phenomena: ‘whistlers’ and micropulsations
Read more of: Very low frequency electromagnetic phenomena: ‘whistlers’ and micropulsationsObservations of natural electromagnetic phenomena, embracing frequencies ranging from millihertz to tens of kilohertz, have made a major contribution to our knowledge of the terrestrial environment extending out to many […]
