Metadata

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

Image title	Sensing device called the SeaBird Conductivity, Temperature Depth (CTD). The device has measures conductivity of water to determine salinity, temperature, and depth. Data is transmitted aboard and plots of variables recorded as the device is lowered through water column. Lids on the grey bottles are closed remotely to capture water samples from specific depth for further testing. USEPA photo by Eric Vance. GPS coordinates available in metadata.
