Spatial patterns of phytoplankton composition and upper-ocean biogeochemistry do not follow carbonate chemistry gradients in north-west European Shelf seas
A key difficulty in ocean acidification (OA) research is to predict its impact after physiological, phenotypic and genotypic adaptation has had time to take place. Observational datasets can be a useful tool in addressing this issue. During a cruise in June-July 2011, measurements of upper-ocean bio...

A key difficulty in ocean acidification (OA) research is to predict its impact after physiological, phenotypic and genotypic adaptation has had time to take place. Observational datasets can be a useful tool in addressing this issue. During a cruise in June-July 2011, measurements of upper-ocean biogeochemical variables, climatically active gases and plankton community composition were collected from northwestern European seas. We used various multivariate statistical techniques to assess the relative influences of carbonate chemistry and other environmental factors on these response variables. We found that the spatial patterns in plankton communities were driven more by nutrient availability and physical variables than by carbonate chemistry. The best subset of variables able to account for phytoplankton community structure was the euphotic zone depth, silicic acid availability, mixed layer average irradiance and nitrate concentration (59% of variance explained).
