Abundance Estimation

2009
Publisher Summary This chapter covers the abundance estimation, the range of techniques by which the size of a population of marine mammals can be estimated. When it is difficult to estimate absolute abundance with an acceptably low bias, relative abundance indices are often used instead.

Isotopic Abundances in Comets

2003
Isotopic ratios in comets provide keys for the understanding of the origin of cometary material, and the physical and chemical conditions in the early Solar Nebula. We review here measurements acquired on the D/H, 12C/13C, 16O/18O, 14N/15N, 32S/34S ratios in dust and gases, and discuss their cosmogonic implications.
