Sr-isotope variations in a composite sill: crystal-liquid processes and the origin of the Skye granites
Read more of: Sr-isotope variations in a composite sill: crystal-liquid processes and the origin of the Skye granitesSr-isotope data from the Rubh’an Eireannaich sill, one of a suite of composite (mafic-silicic) minor intrusions associated with the 59 Ma Skye Intrusive Centre, NW Scotland, indicate that both crystal-liquid […]

A method for preparing large numbers of otolith sections for viewing by scanning electron microscope
Read more of: A method for preparing large numbers of otolith sections for viewing by scanning electron microscopeIn an investigation of the age structure of a population of Notothenia coriiceps Richardson at the South Orkney Islands, Antarctica, the microstructure of otoliths was examined. Progress is reported on […]

Variation in weaning mass of pups in relation to maternal mass, postweaning fast duration, and weaned pup behaviour in southern elephant seals (Mirounga leonina) at South Georgia
Read more of: Variation in weaning mass of pups in relation to maternal mass, postweaning fast duration, and weaned pup behaviour in southern elephant seals (Mirounga leonina) at South GeorgiaFemale southern elephant seals, Mirounga leonina, assemble in large groups and each gives birth to a single pup which is nursed for some 3 weeks. Weaning mass is highly variable; […]

A comparison of midlatitude Pi 2 pulsations and geostationary orbit particle injections as substorm indicators
Read more of: A comparison of midlatitude Pi 2 pulsations and geostationary orbit particle injections as substorm indicatorsBoth the injection of energetic particles at geostationary orbit and ground magnetic observations of Pi 2 wave activity are characteristic indicators of the onset of the substorm expansion phase. Occurrence […]

The polarisation of whistlers received on the ground near L = 4
Read more of: The polarisation of whistlers received on the ground near L = 4The observed polarisation of the horizontal magnetic components of whistler mode signals received at Halley, Antarctica (L≈ 4.3), is in many cases that expected from a simple model of the […]
