High-frequency dissolved oxygen, water temperature, wind speed, and radiation data; stream and in-lake nutrient concentration data; and daily metabolism and nutrient loading estimates for 16 lakes in North America and Northern Europe.

These data were used in the analysis provided in a manuscript by Corman et al. (in review). In lakes, ecosystem structure and processes are influenced by gross primary production (GPP), ecosystem respiration (R), and net ecosystem production (NEP). The rates of these metabolic processes are often controlled by resource availability, which often reflects catchment loads. Although the relationship between catchment loads and in-lake nutrient concentrations may be well defined in specific lakes, we explored how watershed vs. in-lake predictors of metabolism compare across lake types. To do this, we combined stream loads of carbon (C), nitrogen (N), and phosphorus (P) with high frequency in situ monitoring of lake metabolism and in-lake C, N, and P concentrations from 16 lakes spanning a range of latitudes (39 to 64 degrees N), inflowing stream (0 - 6 streams), and trophic status (oligotrophic to eutrophic). The data package includes high-frequency dissolved oxygen, water temperature, wind speed, and solar radiation data as well as daily estimates of GPP, R, and NEP derived from those data. In addition, the data package includes in-lake and stream concentrations of dissolved organic carbon, total nitrogen, and total phosphorus and stream discharge data. The package also includes estimates of daily carbon, nitrogen and phosphorus loading to each lake derived from the stream concentrations and discharge.

本数据集应用于Corman等人待审稿手稿中的分析工作。湖泊生态系统的结构与过程受总初级生产力（Gross Primary Production, GPP）、生态系统呼吸（Ecosystem Respiration, R）以及净生态系统生产力（Net Ecosystem Production, NEP）调控。上述三类代谢过程的速率通常受资源可获得性制约，而资源可获得性往往反映了集水区的输入负荷。尽管在特定湖泊中，集水区负荷与湖内营养盐浓度的关系已有明确阐释，但本研究对比了不同湖泊类型下，流域与湖内代谢预测因子的表现差异。为开展此项研究，我们整合了碳（C）、氮（N）、磷（P）的溪流输入负荷数据，以及16个涵盖39°N至64°N纬度范围、0至6条入湖溪流且营养状态从寡营养到富营养的湖泊的高频原位监测数据，监测内容包括湖泊代谢过程与湖内C、N、P浓度。本数据集包含高频溶解氧、水温、风速与太阳辐射数据，以及基于上述数据推导得到的总初级生产力、生态系统呼吸与净生态系统生产力的日估算值。此外，本数据集还包含湖内与溪流中的溶解有机碳、总氮、总磷浓度数据，以及溪流径流数据。同时，本数据集包含基于溪流浓度与径流数据计算得到的各湖泊每日碳、氮、磷输入负荷估算值。
