Mean concentration ± SD (mmol m-3) of nitrate, nitrite, phosphate, silicate, and ammonia within 20 m from the seabed, and 20–40 m from the seabed from three CTD casts (casts A, B, and D in Fig 9) collected in DFO’s Emerald Basin Vazella Conservation Area (see Fig 9).

The difference in nutrient concentration between these layers is also shown.
