| 520 | 3 |a"We present a climatological analysis of nutrient concentrations for phosphate, silicate, and nitrate+nitrite for the Newfoundland and Labrador (NL) Region based on data collected from 1999-2016. Harmonic analysis of a high sampling frequency hydrographic station (Station 27) provides a depth-dependent description of the seasonal cycle. The climatology quantifies cross-shelf patterns of variation in nutrient concentrations based on surveys of nine oceanographic sections, that are sampled from 1-3 times annually. Overall, mean nutrient concentrations were generally lowest at the surface and increased with depth. Phosphate varied most along transitions in bathymetry, nitrate concentrations increased in deep water towards the shelf break, and silicate concentrations were higher on the shelf compared to slope waters. Spring climatologies showed moderate gradients and some near-surface depletion, summer distributions were characterized by total or near depletion near-surface and stronger gradients deeper than 50m, while the fall was characterized by weakened gradients associated with replenishment in the upper water column. The variable roles that physical and biological processes play across seasons and water column depth were evident at Station 27 and all nine sections"--Abstract, page iv. |
