Macronutrient concentrations from samples collected using rosette on R/V Melville MV1405 (IRN-BRU) cruise in the California Current System in July 2014

This dataset includes macronutrient concentrations from seawater samples collected on R/V Melville MV1405 while investigating the mosaic of the California Current System in July 2014 using the shipboard rosette. It includes depth profiles of an active upwelling site nearshore over the shelf in northern California (Station 2), a more aged upwelling site offshore of the shelf break in southern Oregon (Station 28), a station in the Santa Barbara Basin that got suboxic in the lower depths of the water column (Station 29), and a set of stations (9, 12 and 15) that show two cyclonic eddies, one two months younger (station 9) than the other (station 15), but both coming from roughly the same place and moving offshore, with station 12 in between them in an offshoot of the California Current.

The chief scientist of the cruise was Ken Bruland. Nutrient samples were analyzed by Tyler Coale. See related datasets for additional macronutrient concentrations and dissolved trace metal concentrations found in GoFlo and surface samples collected on MV1405.

本数据集汇集了2014年7月在R/V Melville MV1405号船调查加利福尼亚洋流系统拼接图时，于船载旋翼采水器采集的海水样本中的宏量营养素浓度。数据包括近岸北部加利福尼亚架上活跃上升流站点的深度剖面（站点2）、位于南部俄勒冈州架外断层的较老上升流站点（站点28）、圣巴巴拉盆地中的一站，该站的水柱下层出现缺氧现象（站点29），以及一组站点（9、12和15），这些站点展示了两个气旋涡流，一个比另一个年轻两个月（站点9），但两者均源自大致相同的位置并向外海移动，站点12位于它们之间的一个加利福尼亚洋流的支流中。此次航次的首席科学家为Ken Bruland。营养素样本由Tyler Coale进行分析。参见相关数据集以获取更多宏量营养素浓度和溶解性微量元素浓度，这些数据来源于MV1405号船采集的GoFlo和表观样本。
