Gulf Watch Alaska Forage Fish Component: Nutrients data from CTD Sampling Stations in Prince William Sound, Alaska 2012-2015

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. Nutrient samples were collected during the summer in Prince William Sound, Alaska (2012-2015) at every station. The water samples for inorganic nutrient concentration (µM) analysis were frozen in clean 60 ml HDPE sample bottles, and later processed at the University of Washington Marine Chemistry lab using established protocols (UNESCO 1994). The analysis of the concentration of these samples are provided in this dataset (NO2, NO3, PO4, and SIOH4). We collected water samples from surface (0 meters), 10 meters, and bottom depth in conjunction with conductivity-temperature-depth profiles.

本数据集隶属于阿拉斯加海湾观测（Gulf Watch Alaska, GWA）长期监测计划的远洋监测组分。2012年至2015年夏季，研究人员于阿拉斯加威廉王子湾的全部监测站位采集营养盐样本。用于无机营养盐浓度（μM）分析的水样被分装至洁净的60毫升高密度聚乙烯（HDPE）样品瓶中冷冻保存，后续于华盛顿大学海洋化学实验室依照既定规程（UNESCO 1994）完成处理与分析。本数据集包含这批水样的浓度分析结果，涵盖亚硝酸盐（NO₂）、硝酸盐（NO₃）、磷酸盐（PO₄）与硅酸（SIOH₄）。本次采样同步采集了表层（0米）、10米水深及底层水深的水样，并同步获取了温盐深剖面数据。
