The surface called "sea floor" means the lower boundary of the ocean. The *parameter* at the sea floor is that adjacent to the ocean bottom, which would be the deepest grid cell in an ocean model and within the benthic boundary layer for measurements.

Suspended sediment means undissolved solid particles. The surface called "sea floor" means the lower boundary of the ocean. The *parameter* at the sea floor is that adjacent to the ocean bottom, which would be the deepest grid cell in an ocean model and within the benthic boundary layer for measurements.

"Mass concentration" means mass per unit volume and is used in the construction "mass_concentration_of_X_in_Y", where X is a material constituent of Y. A chemical species or biological group denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". Suspended sediment means undissolved solid particles. The surface called "sea floor" means the lower boundary of the ocean. The *parameter* at the sea floor is that adjacent to the ocean bottom, which would be the deepest grid cell in an ocean model and within the benthic boundary layer for measurements.
