We recently recovered two ‘Smart Buoy’ systems operated by
Cefas. Several such observing systems have been deployed at various stations
around the Celtic Sea since March of 2014. These systems allow us to understand
variation in the ocean in a way that is similar to weather monitoring. The
sensors can record a variety of variable crossing physics to biogeochemical
themes. These systems allow us to see how weather and climate affect surface
ocean conditions and the growth of marine algae via primary production. It can
measure changes in salinity, primary production nutrients, chlorophyll
fluorescence, dissolved oxygen, and suspended particles. There is also a string
of temperature sensors down to 60 m depth.

We used the ship’s sensor and sampling systems to calibrate
the buoy sensors, both when deployed and recovered to check that everything is
working as expected and calibrate any sensor drift. Together with the sediment
samples being take in the area, these long-term observatory observations allow
us to better understand the variation in way that can be achieved when ships
are not present. This helps bridge understanding between site visits over the
change of seasons.
