NERC EDS UK Polar Data Centre. https://doi.org/10.5285/3d7b47b5-eb0b-40d9-948a-1ae05bd62250 Fieldwork was undertaken at Blaso epishelf lake, Northeast Greenland between 19th July and 11th August 2017. Tidal variation was measured using a water pressure transducer between the 24th July to 8th August 2017. The tidal measurements are therefore presented as three measurement intervals: Interval 1 (25th July - 29th July), Interval 2 (29th July - 2nd August), and Interval 3 (2nd August - 12th August).

This uses a silicon strain gauge to measure water pressure variations, with a manufacturer: cited accuracy of 0.05 percent full scale (FS) and a resolution of 0.0034 percent FS. Water pressure variations were corrected for barometric (atmospheric pressure) variations using measurements from a VanWalt BaroSCOUT instrument and the Aqua4Plus software package. The LevelSCOUT was secured to a stake submerged in the western end of the lake (79.59083 N, -22.6075 W), and the BaroSCOUT was secured to a stake on the lakeshore less than 50 m away. Overnight on 28/29th July 2017 the tidal pressure transducer stake was impacted by windblown lake ice floes. The transducer continued to record tidal information but with anomalously high-water depth readings due to the tilted stake. On 2nd August the lake ice had moved and the stake was re-positioned to the vertical at the same site. The tidal measurements are therefore presented as three measurement intervals: Interval 1 (25th July - 29th July), Interval 2 (29th July ? 2nd August), and Interval 3 (2nd August - 12th August). The breakpoints of the record are: Interval 1: Record 4 to Record 1273 Interval 2: Record 1275 to Record 2491 Interval 3: Record 2495 to 3475 Data headings are: Record_number: sequential numbering Device_date_time: timezone is UK Local_date_time: Measurement times are all corrected by -3 hours to correct from UK (device time) to local Greenland time Corrected_pressure_h2o: Pressure recorded by submerged transducer, corrected for atmospheric variations Pressure_cm_h2o: pressure measurement on submerged LevelScout Temperature_degC: temperature of water SensorPressure_cm_h2o): air pressure from BaroScout used to correct LevelScout for air pressure variations Barometric_date_time: time of barometric reading used to correct LevelScout Data collection: VanWalt LevelSCOUT VanWalt BaroSCOUT Aqua4Plus software package Data quality: The data are not tied to a benchmark.
