Abstract: A sampling apparatus that allows multiple uncontaminated samples to be taken from hydrothermal vents and the oceanic or limnological water column. The apparatus includes a sampling nozzle for taking in the sample. A sample collection unit is in fluid communication with the sampling nozzle and includes at least one sampling module for the collection of a predetermined type of sample. A fluid intake module is in fluid communication with the sample collection unit and the sampling nozzle. The fluid intake module includes at least one pump for drawing a sample fluid through the sampling nozzle and sample collection unit. A control module is in electrical communication with the fluid intake module. The control module includes a micro-controller for controlling the fluid intake module and a computer readable memory for storing sampling data for use by a user.
