Compare parameters in the date range selected below with those in the same date range one year later.

Data using the 2.5µm filter are available from the end of November 2022. Data from the 10ml settling cell have only been collected from the end of October 2023, so it is not possible to run annual comparisons using this technique yet.

Date range from to

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 (range 0.5-10.5m)
× Sample salinity (range 25-32‰) collected from Jan 2024.
× Temperature (range 6-20°C).
× Wave Power (range 0-50kW/m, 5 day boxcar available)

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

Select species to display:
You can only display data for 2.5µm sampling method, as we do not yet have a full year of data from the 10ml settling cell.
