Pelican has been in Albion Dockyard for maintenance and is now ‘shipshape and Bristol fashion’, an expression that, according to our captain Ben Wheatley, was coined here, as a reflection of the superb craftsmanship of shipwrights in this historic dock.
Before leaving, we commissioned a TriLux fluorescence sensor on loan from Chelsea Technologies. For me, it is always a delight to ‘play’ with a new instrument, and this one did not disappoint: easy to operate, no-nonsense data logging and seamless plug-and-play with our laptop. ‘Shipshape’, too!
We’ll use TriLux for spot sampling of depth profiles along a Secchi disk to determine key algal parameters involved in photosynthesis (chlorophyll a and phycoerythrin), as well as turbidity.
We will contribute our data to the Secchi Disk Foundation, who research the global distribution of primary producers that underpin the marine food web.
