Hypolimnion Temperature and Oxygen Measurements from Esthwaite Water, 2005-2009

Fortnightly measurements of hypolimnion temperature and dissolved oxygen concentration from Esthwaite Water in Cumbria, UK. The dataset covers a five-year period from January 2005 through December 2009, collected by the UK Centre for Ecology & Hydrology.

Use Cases

• Analyze long-term trends in hypolimnion temperature (TEMP) to study lake thermal structure changes over the 2005-2009 period.
• Model the relationship between hypolimnion dissolved oxygen concentration (DO) and seasonal temperature variations.
• Use the fortnightly sampling frequency to assess the rate of oxygen depletion in the lake's deep water layer.
• Correlate temperature and oxygen measurements from the 13.5-15m depth range with meteorological or catchment data.

Strengths

• Provides a continuous five-year time series from 2005 to 2009.
• Measurements are taken at a consistent depth range of 13.5 to 15 meters.
• Data collected through a structured, long-term monitoring program with fortnightly sampling.
• Originates from a recognized research organization, the UK Centre for Ecology & Hydrology.

Limitations

• The dataset is limited to a single lake (Esthwaite Water), restricting geographical generalizability.
• Data is over a decade old, ending in 2009, which may not reflect current lake conditions.
• Contains only two primary physical/chemical variables (temperature and oxygen), limiting multivariate analysis.
