Biologically relevant macronutrients, nitrate + nitrite, silicate, phosphate and ammonia, were measured at all sites throughout the study. Nitrate + nitrite values (NOx) at the surface showed clear seasonal trends, peaking over winter and drawing down to near zero in summer and autumn. Phosphate concentrations also reached a peak in winter, which was associated with Southern Ocean influence. Median ammonium concentrations at all sites were generally
本研究在所有采样站点均测定了生物相关的大量营养盐，包括硝酸盐+亚硝酸盐、硅酸盐、磷酸盐与氨（铵）。表层水体中的硝酸盐+亚硝酸盐浓度（NOx）呈现清晰的季节变化趋势：冬季达到峰值，夏季与秋季则降至接近零的水平。磷酸盐浓度同样在冬季达到峰值，这与南大洋的影响相关。所有采样站点的铵态氮浓度中位数总体上
