Dear Roy, Dear Jonathan,
Thank you for the feedback. I see? that sediment might be ambiguous.
Would "seabed sediment" or "marine seabed sediment" be an acceptable
alternative?
? moles_of_nitrogen_per_unit_area_in_seabed_sediment
This would clarify that the sea floor is meant as location of the
sediment. It would also clarify that not bare rock is meant.
Cheers,
Daniel
