I have the pleasure, rather than the responsibility, of being the leader of Black and Bloom. All my scientific Christmases have come at once with this project. We have a great team of established academics, four exceptionally talented post docs, and an expanding group of, currently three, bright, able and motivated post grads. Our international project partners are eminent in their fields, and very generous with their help and support. What is there not to like about fronting up for this group of researchers?
Black and Bloom will undertake transformative work on the combination of physical, chemical and biological factors that control the albedo of the Greenland Ice Sheet. My contribution to the project science will be to help define the geochemical and biogeochemical factors which impact of the growth of pigmented microorganisms in the snow and ice. I have a long standing interest in the rock-water-microbe interactions, a spectrum of which will be occurring in the different microbiological niches on the surface of the ice sheet. I am particularly interested in how the microbes acquire and recycle nutrient from atmospheric and snow/ice sources. This is likely to be one of the key drivers, following the presence of liquid water, of microbial growth and pigmentation.
I am a very proud Welshman. My interests include rugby (Wales, Ebbw Vale and Bath), the mighty Wolves, Mets and Fins, music, poor photography, cooking, bird watching, bridge, allotmenteering, red wine and real ale.
Black and Bloom’s Microbiologists
Professor Alex Anesio – Package Leader
Alex is Professor of Biogeochemistry in the Bristol Glaciology Centre at the University of Bristol. He gained his PhD in Limnology from Lund University, Sweden in 2000. His research combines molecular and biogeochemical approaches to determine microbial functionality and activity in the cryosphere. His previous research demonstrated that microbial activity at the surface of glaciers and ice sheets are responsible for significant carbon and nitrogen fixation with implications for biogeochemical cycles at local and global scales. He is one of the advocates that glaciers and ice sheets are one of the biomes of Earth. He is author in over 65 peer-reviewed papers and has previously secured funding as PI from NERC, The Royal Society, The Leverhulme Trust and The Nuffield Foundation. Recently, he is also the coordinator of an Innovative Training Network, which includes 13 beneficiaries and 15 PhD students (H2020-MSCA-ITN-2015) with funding from the EU for investigating microbial communities and processes in the Arctic.

Alex Holland – PhD student of the MicroArctic Innovative Training Network
Alex is a PhD student of the MicroArctic Innovative Training Network (European Commission’s Marie Sklowdowska Curie Actions program, project 675546) based at the University of Bristol within the School of Geographical Sciences. She obtained her bachelors in Geology from the University of South Carolina where she studied the organic geochemical variability of different types of supraglacial impurities on two Alaskan glaciers. For her PhD, Alex is investigating nutrient cycling within supraglacial habitats throughout the arctic. Specifically, she is interested in the sources and sinks of inorganic and organic nutrient stocks, and how these interact with supraglacial microbial communities to determine the overall nutrient landscape of surface ice and the implications for down-stream ecosystems. Alex will join the Black and Bloom team during field work on the Greenland Ice Sheet in addition to her other MicroArctic field sampling campaigns.
Miranda Nicholes – PhD student
Miranda is a PhD student working on the Black and Bloom project at the University of Bristol. During her undergraduate degree in Geography at the University of Bristol, she focused her dissertation research on the microbiology of cryoconite holes. She investigated whether the presence of different dominant minerals affected the type of microbial community which developed within cryoconite holes. For her Master’s dissertation, she then focused on the release of dissolved organic carbon resulting from the viral lysis of bacteria cells. These two projects caused her to catch the glaciology bug (excuse the pun!) and she was thrilled to be accepted onto the Black and Bloom Project. Within the project, Miranda will be assessing the bacterial assemblages present within Greenland Ice Sheet surface ice, and how these interact with ice algal communities and nutrient stocks to influence supraglacial dynamics.
Black and Bloom’s Particulate Experts
Professor Liane G. Benning – Package Leader
firstname.lastname@example.org email@example.com @lianegbenning lianegbenning.wordpress.com
I am extremely proud to be part of this exciting project. Together we will tackle one of the fundamental problems affecting our extremely fast changing planet – the melting of the Arctic. We have an impressive combination of skills on the team and I look forward not just to the field work but also to the results from the lab work.
I am based both at the Cohen Laboratories in the School of Earth and Environment at the University of Leeds where part of this NERC grant is hosted, but am also building a new interface-geochemistry group at the German Research Centre for Geosciences, GFZ in Potsdam, Germany.
In my group we study various molecular level microbe-mineral-fluid interactions. Further info can be found here here. With respect to the Arctic, where I have worked since 2003, we focus on evaluating mineral transformations in iceberg and glacial meltwaters to quantify the global element cycle. My current focus is on bio-geo weathering and microbial succession in glacial forefields, bio-colonisation of snow and ice, the genomic makeup of algae on snow and ice, and the effects that algae have on albedo,. For Black and Bloom, the Leeds and GFZ teams will focus on aerosol inputs, microbe-particulate interactions and various ‘omics’ of the microbial communities on the Greenland Ice Sheet. Besides the NERC funding for Black and Bloom and Arctic Soils I also co-lead or am part of 3 large EU Training Networks on microbe-mineral-fluid interface reactions (CO2-react, Micro—Arctic and MetalAid).

His skill sets include competence in standard hydrometeorological techniques, ground penetrating radar (GPR), GIS, image analysis and, increasingly, tools for microbiological investigations (e.g. flow cytometry).
Dr Joseph Cook – Post-Doctoral Research Associate
firstname.lastname@example.org, @tothepoles, http://tothepoles.wordpress.com, ORCHID ID: 0000-0002-9270-363X
Joseph is responsible for measuring and modelling the spectral reflectance and albedo of the ice sheet surface as it evolves over melt seasons. This is important because the reflectivity of the ice determines how much solar energy is absorbed and used to melt ice. As ice melts, water can accumulate in spaces between ice crystals and impurities gather on the ice surface, causing the reflectivity of the ice to decrease. At the same time, algal growth adds dark matter to the ice and also exacerbates water and impurity accumulation. Joseph’s field measurements and radiative transfer modelling will quantify these processes and advance our understanding of the role of microbes in the melting of ice sheets.
Joseph has been studying the interactions between biology and ice surface albedo since 2008, primarily focusing upon cryoconite (biologically engineered granules that provide habitats for remarkably diverse ecosystems on ice surfaces). His recent work has shown how cryoconite sculpts ice into comfortable habitats for microbial activity by exploiting their own low albedo. Previous projects have taken him into the field in Greenland, Iceland and Svalbard.
