A digital camera is an electronic device that captures photographs and videos by converting light into digital data, storing images on memory cards instead of film. Unlike traditional film cameras, digital cameras allow instant image review, deletion, and editing. Uses CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide Semiconductor) image sensors to convert light into electrical signals.

A vibracorer (also called a vibratory corer) is a specialized sediment sampling device used to collect continuous cores of unconsolidated, water-saturated sediments from marine, estuarine, and wetland environments. It is widely employed in coastal and marine surveys for geologic, geochemical, and environmental studies.
