1 Geographic patterns of species distribution At the global scale, the thermohaline ‘conveyor belt’, which rules the ocean circulation, not only redistributes heat (Gage & Tyler, 1991) but also plays a pivotal role in the distribution of pelagic species, which may disperse following these deep‐sea corridors and colonize deep‐sea basins from shallower environments (McClain & Mincks Hardy, 2010). g. , 2008). g. UNESCO, 2009). g. Longhurst, 1998). The boundaries of these assemblages are, how­ ever, sometimes ‘fuzzy’ and may be greatly affected by vertical and/or h­orizontal movements of water masses.

Consideration of these characteristics provides a useful biological context for the sampling techniques that are covered in sub­ sequent chapters of this book. 1 Introduction Progress toward knowledge of the deep ocean and of the living forms which inhabit it has been slow compared to the study of the more accessible shallow marine environments, hampered by obvious technical, logistic and economic constraints. The first global biological survey of the deep sea, where the ocean floor was sampled in a system­ atic way, was undertaken from the HMS Challenger in the years 1872–1876 (Murray, 1895).
