This app allows users to explore limnological data from three lakes in the Poconos Mountains region of Pennsylvania, USA. Lake Giles is a blue lake (oligotrophic), Lake Lacawac is a brown lake (dystrophic), and Lake Waynewood is a green lake (eutrophic). Data on these lakes have been collected since 1988, resulting in an extensive limnological data set. Through user-selected controls in this app, graphs and tables are generated to visualize long- term trends. The table below includes geographic and limnological descriptors of the lakes. Water chemistry values are July averages from the three most recent years of the dataset.

Data Use Policy

By accessing these data, data users agree to contact the data authors to ensure appropriate collaboration and/or co-authorship prior to using these data in publications. The Global Change Limnology Laboratory has made every effort to ensure the accuracy of the data provided here. However, the data set is extensive and complex, and we cannot guarantee that it is error-free. These data are part of ongoing data collection; thus users should be aware that these data sets and occasionally methods are periodically updated. These data are provided "as-is", and users take responsibility for any damages that occur due to misuse or misinterpretation of these data. Users are encouraged to carefully consider the original data set, including methods and other metadata, when drawing conclusions.

Summary of long-term summer data

Points are a summer average (May-August) of long-term abiotic data collected in three lakes in the Poconos region of Pennsylvania (USA). Significant trends (p<0.05, Mann-Kendall nonparametric trend test) are denoted by a solid black line. A dashed line indicates a non-significant trend.

Methods and metadata can be found at the Environmental Data Initiative.

Daily averages of high frequency data

Data were collected with high frequency sensors in three lakes in the Poconos region of Pennsylvania (USA). Sensors include miniDOT (temperature and dissolved oxygen), miniPAR (PAR irradiance), and Cyclops-7 loggers (chlorophyll and cDOM) . Data displayed are daily averages. Heat maps are created by interpolating between sensor depths and take longer to render.

Summary of long-term summer zooplankton data

Long-term zooplankton data can be viewed by summer month or as a summer average (May-August). Significant trends (p<0.05, Mann-Kendall nonparametric trend test) are denoted by a solid black line. A dashed line indicates a non-significant trend.
