Description:
The unique identifier used for each dive transect. For example, ALB18-A1-1 where ALB is the DFW_short_code for Albion Bay; 18 is the year (2018); A1-1 is the randomized transect. For those years with a letter preceding a number, the letter refers to a depth stratum in feet: A=0-15, B=16-30, C=31-45, D=46-60 ft.
