ABSTRACT:
Apparatus for obtaining a series of concentrated samples of dissolved, particulate or emulsified substances from seawater. A relatively large measured volume of seawater is pumped through each of a series of in situ sampling chambers containing filtration, adsorption, absorption, or other retentive material. The instrumented housing with appended sampling chambers is preferably suspended from a surface vessel by an electrical cable through which it is remotely controlled and powered to obtain measured samples at various depths. Alternatively, a programmed controller and battery power pack can be attached to obtain an unattended time series of samples from a fixed location either on the sea floor or suspended beneath a buoy.
