Summary
Introduction
Plankton have inhabited the Earth's oceans for hundreds of millions of years as evidenced by the fossil record. The exterior covering of identifiable dinoflagellates, for example, are well preserved in Mesozoic rock strata. Pelagic diatoms possess siliceous frustules with identifiable species dating from early Cretaceous sediments (see Falkowski et al., 2004). Given the extent of fossil plankton, it is apparent that a drifting mode of life has been a successful means for survival in the sea for much of life's history.
With the importance of plankton in marine ecosystems, it is surprising that biological oceanographers have only recently begun to use drifting, or more formally Lagrangian, techniques. However, as with other aspects of biological oceanography, the Lagrangian ‘tools’ for studying plankton are relatively recent, and have often followed technique development by physical oceanographers and engineers. The main goal of this chapter is to summarize how biological oceanographers have applied Lagrangian and related methods to further our understanding of oceanic plankton distributions and dynamics, as well as biogeochemical processes. Our target audience is physical oceanographers and mathematicians who will hopefully gain some benefit from this exercise, while biological oceanographers may also be encouraged to further consider Lagrangian approaches in their field studies. We include studies on bacterio-, phyto-, zoo-, and ichthyoplankton and discuss the advances made in specific sub-disciplines of biological oceanography through the use of Lagrangian techniques. This review is timely in that new, low power sensors are now being adapted for deployments on a variety of Lagrangian platforms.
