Compare selected parameters starting on a given date with those in subsequent years.

This graphical utility allows you to compare parameters from a set start date with those from one year later. Data using the 2.5µm filter are available from the end of November 2022 to the end of March 2025. Data from the 10ml settling cell have been collected from the end of October 2023.

Type of sample: 2.5µm quantitative. 10ml settling cell.

Compare selected data for the period starting for the period of month(s) with that for the following year(s).

Include physical parameters: See footer for notes.
× River Wyre height at St Michaels (range 0.3-5m, 5-day boxcar available)
× Sunlight hours PCM at Bradford (range 25-250 hrs)
× Tide height at Fleetwood when the sample was collected (range 0.5-10.5m)
× Sample salinity (range 25-34‰) collected from Jan 2024.
× Sample turbidity (range 20-150 JTU) collected from May 2024.
× Seawater temperature (range 6-20°C).
× Wave Power (range 0-50kW/m, 5 day boxcar available)

Use 5-day boxcar values (available for wave power and river height)
