Conwy catchment - Llyn Conwy water temperature profile data (2006 - 2008)

In-lake temperature data for a peatland headwater lake of the Conwy catchment, North Wales are presented from November 2006 until December 2008. The Lake for which the data represents is Llyn Conwy situated on the Migneint blanket bog within Snowdonia National Park. The data is from a temperature string suspended from a buoy anchored above the deepest part of the lake. Temperature is recorded at 2m intervals throughout the lake profile from 1 to 19m. The purpose of this data is to investigate water column stability and to determine when, and to what degree stratification/mixing occurs and to make inferences about the effect of this on productivity, nutrient and chemical cycling. Note: there are gaps in this data set due to equipment/battery failures and/or freezing of the lake surface which meant it was not accessible.

Provenance & quality

In-lake temperature measurements were taken hourly and recorded automatically on to a CR10X data logger. The sensors used were high-precision platinum resistance thermometers (PRTs), encapsulated in a stainless steel sheath. The equipment was accessed via boat bi-monthly to download the data to a laptop which was then transferred on to the CEH shared drive which is in turn backed up each evening. The data was then integrated into a master file along with a diary entry for the visit detailing any relevant information or observations. This metadata was then used to help quality check the raw data, along with plotting the data to identify outliers that may be indicative of equipment failure.
