Abstract
This note reports methods used in 2019 to obtain and process phytoplankton
data from the Lorn Pelagic Observatory ( 56.5N, 5.5W) for comparison with long-term changes in Sea-Surface Temperature (SST) according to ICOADS. The methods, and some associated issues are illustrated with data for Diatoms and the dino agellate genus Cer-atium. Analyses were also made for `Reliably Identied Phototrophic Armoured Dinoflagellates' (RIPAD) and (oligotrich) Ciliates. Therehas been a signicant upwards trend in SST and a signicant downwards
trend in Diatoms cells/L, over the period from 1970 to 2015 (with no data 1982-1999) and these trends are correlated (table 3). There were no long-term temporal trends in the abundances of the other groups, but RPIDAL and Ciliates cells/L were signicantly inversely correlated with SST. The work is a contribution to the ICEGRAPH project.
