Biometric data illustrating species-specific growth response of coccolithophores to Palaeocene-Eocene environmental change (NERC Grant NE/H017291/1)

These data were produced within the objectives of the NERC grant (alongside collaborator Gibbs at NOC, Southampton) and predominantly comprise biometric data collected under light microscope at x1500 magnification from the coccolithophore taxon Coccolithus pelagicus, a heavily calcified taxon with a long fossil record. The data was collected as part of a collaborative research effort bringing together the modern and fossil consortia within the UK Ocean Acidification research programme. The data are from batch culture experiments on both modern sub-species of C. pelagicus and provide cell size, coccosphere size, coccolith size and number of coccoliths per cell. The same parameters were measured from C. pelagicus from North Atlantic field and sediment trap samples from inside and outside bloom conditions. Again, the same parameters were also measured from C. pelagicus from exceptionally well-preserved fossil material from several shelf and off-shelf marine locations including New Jersey, Tanzania, California and the Bay of Biscay.

Statement

Using light microscopy (LM) we imaged and measured 1173 fossil coccospheres from across the PETM interval. Coccosphere images were collected from Bass River onshore Ocean Drilling Program core, New Jersey, Lodo Gulch, central California, Kilwa, Tanzania Drilling Project Site 14, and Deep Sea Drilling Project (DSDP) Site 401 in the Bay of Biscay. Biometric measurements were made on images taken under crossed polarised light at x1600 magnification, with a colour digital camera (Olympus DP71), using CellD software supported by Olympus. Three biometric parameters of the coccospheres (fossil and modern) were measured: 1. the number of coccoliths comprising each coccosphere (CN), 2. external coccosphere diameter including coccoliths (Ø), and, 3. coccolith size, which was measured from the tube cycle and converted to coccolith length (CL).
