I want to establish a heading for Marc J. Russell, author of Verification of bay productivity measurement by remote sensors. (ocm76884043). There is already a record for this title in OCLC with the heading Russell, Marc J.

I know that this is the same person listed as author of the thesis: Net ecosystem metabolism in Texas shallow water estuaries (ocm68816448)
Russell, Marc James |d 1975

and likely Marc Russell (ocm54855207 and ocm54488377)

I'm unsure how to determine which version of the name to use. Can someone please tell me if I can use the fullest form as found on the thesis?
Russell, Marc James, |d 1975
Russell, Marc J. |q (Marc James), |d 1975
Russell, Marc J.

Thank you for your help.
