ABSTRACT:
A method includes providing a sampling device having a sampling chamber therein, a pump operatively coupled to the sampling chamber, and a drive means coupled to the sampling chamber; situating the sampling device against an underwater boat hull having contaminants attached thereto, wherein situating the sampling device against the underwater boat hull causes water to be disposed within the sampling chamber; activating the pump to remove a portion of the water from the sampling chamber, wherein negative pressure is created within the sampling chamber and a watertight seal is formed between the sampling chamber and the underwater boat hull; activating the drive means to remove a sample of the contaminants from the underwater boat hull, wherein the sample of the contaminants is collected in the sampling chamber; deactivating the mechanical drive means; and sealing the sampling chamber, wherein the sample of the contaminants is stored within the sampling chamber.
