The distribution, abundance and community structure of marine birds in southern Drake Passage and Bransfield Strait, Antarctica
Read more of: The distribution, abundance and community structure of marine birds in southern Drake Passage and Bransfield Strait, AntarcticaWe studied the distribution and abundance of marine birds in Bransfield Strait and southern Drake Passage during January and February 1985. We identified clusters of bird species, “communities” with similar […]

Ion cyclotron absorption at the second harmonic of the oxygen gyrofrequency
Read more of: Ion cyclotron absorption at the second harmonic of the oxygen gyrofrequencyThe ray paths of unstable electromagnetic waves generated inside the plasmapause during magnetic storm conditions are followed using the HOTRAY code. Unducted waves which are preferentially generated in the field […]

Quasielectrostatic and electrostatic approximations for whistler mode waves in the magnetospheric plasma
Read more of: Quasielectrostatic and electrostatic approximations for whistler mode waves in the magnetospheric plasmaThree model electron distribution functions representative of the region between the plasmapause and the geostationary orbit are constructed. These models are used to compare numerical solutions of the hot electromagnetic […]

Ray tracing of auroral Z mode radiation, AKR and auroral hiss
Read more of: Ray tracing of auroral Z mode radiation, AKR and auroral hissWhile observed frequency bandwidths of auroral Z mode radiation cannot be directly accounted for in terms of direct cyclotron maser instability generation, ray tracing in a hot plasma indicates that […]

Effects of density gradients on the growth and damping of electrostatic electron cyclotron harmonic waves
Read more of: Effects of density gradients on the growth and damping of electrostatic electron cyclotron harmonic wavesThe HOTRAY ray tracing code is used to study the refraction of electrostatic waves into Z mode radiation, and to calculate the path integrated growth rate. A plasma density model […]
