+1 for Roy's choice.
Can you explain the following for the acoustically naive? "I assume the data would need some additional description to denote the vertical extent of the measurement, such as cell_bounds and cell_methods='Z:sum'."

'two-way' is a possible alternative to 'roundtrip' but I think the former carries unfortunate seismic semantic implications, so 'roundtrip' is better for IES. Including 'in_sea_water' is also essential to clearly distinguish it from seismic data.
