In all entities from this site (LH-70s-1 (entity_id = 50), LH-70s-2 (entity_id = 51), LH-70s-3 (entity_id = 52)), the depth_sample duplications are for levels at which the line of samples has been shifted laterally along a growth layer (e.g. the sample line had to sidestep to avoid a vug or the same layer had to be sampled across a break in the slab).
