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.

Whole rock geochemical data from the Alpine Fault Zone (NERC Grant NE/J022128/1)

Whole rock geochemical data from the Alpine Fault Zone. These data have been generated from systematic sampling through the Deep Fault Drilling Project - Phase 1 rock cores and from analyses of cuttings retrieved during the Deep Fault Drilling Project - Phase 2. Geochemical analyses on the fault rocks to understand the conditions at which they were deformed. The dataset is associated with the UK component of a major international campaign, the Deep Fault Drilling Project (DFDP). to drill a series of holes into the Alpine Fault, New Zealand.

Alkenone and foraminiferal carbon isotope data from Site 999 (NERC grant NE/H006273/1)

Temperature reconstructions indicate that the Pliocene was ~3 degrees C warmer globally than today, and several recent reconstructions of Pliocene atmospheric CO2 indicate that it was above pre-industrial levels and similar to those likely to be seen this century. However, many of these reconstructions have been of relatively low temporal resolution, meaning that these records may have failed to capture variations associated with the 41 Kyr glacial-interglacial cycles thought to operate in the Pliocene. These data represent new, high temporal resolution alkenone carbon isotope based record of pCO2 spanning 0 to 0.2 and 2.6 to 3.3 million years ago from ODP Site 999 (supplementing our other data repository focused on 2.8 to 3.3 million years ago). Our record allows a) direct comparison of alkenone-derived pCO2 from the Pleistocene to that of the Pliocene and b) comparison of the former to the ice core record. The raw data are sea surface temperature estimates from the Uk'37 proxy, foraminiferal and alkenone d13C values, from which carbon isotope fractionation during photosynthesis (ep) can be calculated. Using nutrient concentrations (growth rate correction) and SSTs, these ep values can be converted into [CO2(aq)] which in turn can be used to calculate pCO2.

The Geochemistry of Fossil Pigment Preservation (NERC grant NE/J023426/1)

These data represent a massive synchrotron based programme to study ancient life. Not all of these data have been processed yet, nor have we published all of the results that we intend to. These data are still very much a work in progress. NERC grant abstract: Building on our previous successes with identifying and mapping the chemical residues of eumelanin and beta keratin, herein we propose an analytical and experimental plan to enhance our ability to detect and image key components of soft tissue. First of all we will perform a series of experiments with extant soft tissue so that we can monitor and determine the breakdown reactions of organic compounds as a function of host lithology, moisture content, and trace metal inventory. Secondly, we will complete an analytical programme, including SRS-XRF imaging, which will include these experimental run products as well as a series of time-stepped fossil samples of varying ages and host lithology so that we may build up a database which allows us to refine our general understanding of reaction paths during fossil degradation. Because the techniques we have developed are non-destructive we now have opened up the possibility for detailed analysis of extremely rare specimens which hold important information but cannot be destructively sampled. Finally, these experimental and analytical results from fossils and comparable extant species will be combined in order to answer several critically important questions in palaeontology, biology, and geochemistry.

Full chemical analysis results of volcanic plume samples during Holuhraun eruption (Iceland), collected in January 2015 (NERC grant NE/M021130/1)

The dataset has been published open-access in Ilyinskaya et al. (2017), Earth and Planetary Science Letters, 472, 309-322 https://doi.org/10.1016/j.epsl.2017.05.025 This study quantifies the air quality impact of Holuhraun eruption 2014-2015 on populated areas in Iceland. Specifically we trace the evolution of the plume chemistry from the eruption site to 2 key areas of population: Reykjahlid, which is the nearest municipality to Holuhraun at 100 km distance, and Reykjavik capital area, which hosts ~60% of Iceland's population, 250 km distance. This dataset is the full chemical analysis of filter pack samples of volcanic gas and aerosol, including trace species (e.g. heavy metals).
