Holocene carbon dynamics at the forest – steppe ecotone of southern Siberia (2016)
Journal Article
Mackay, A. W., Seddon, A., Leng, M. J., Heumann, G., Morley, D., Piotrowska, N., Rioual, P., & Swann, G. E. (2017). Holocene carbon dynamics at the forest – steppe ecotone of southern Siberia. Global Change Biology, 23(5), https://doi.org/10.1111/gcb.13583

The forest–steppe ecotone in southern Siberia is highly sensitive to climate change; global warming is expected to push the ecotone northwards, at the same time resulting in degradation of the underlying permafrost. To gain a deeper understanding of... Read More about Holocene carbon dynamics at the forest – steppe ecotone of southern Siberia.

Ecology under lake ice (2016)
Journal Article
Hampton, S. E., Galloway, A. W., Powers, S. M., Ozersky, T., Woo, K. H., Batt, R. D., Labou, S. G., O'Reilly, C. M., Sharma, S., Lottig, N. R., Stanley, E. H., North, R. L., Stockwell, J. D., Adrian, R., Weyhenmeyer, G. A., Roberts, S., & Swann, G. E. (2017). Ecology under lake ice. Ecology Letters, 20(1), 98-111. https://doi.org/10.1111/ele.12699

Winter conditions are rapidly changing in temperate ecosystems, particularly for those that experience periods of snow and ice cover. Relatively little is known of winter ecology in these systems, due to a historical research focus on summer "growing... Read More about Ecology under lake ice.

Biogeochemical cycling in the Bering Sea over the onset of major Northern Hemisphere glaciation (2016)
Journal Article
Swann, G. E., Snelling, A. M., & Pike, J. (in press). Biogeochemical cycling in the Bering Sea over the onset of major Northern Hemisphere glaciation. Paleoceanography, 31(9), https://doi.org/10.1002/2016PA002978

The Bering Sea is one of the most biologically productive regions in the marine system and plays a key role in regulating the flow of waters to the Arctic Ocean and into the subarctic North Pacific Ocean. Cores from IODP Expedition 323 to the Bering... Read More about Biogeochemical cycling in the Bering Sea over the onset of major Northern Hemisphere glaciation.

Insights into the transfer of silicon isotopes into the sediment record (2016)
Journal Article
Panizzo, V. N., Swann, G. E., Mackay, A., Vologina, E., Sturm, M., Pashley, V., & Horstwood, M. (2016). Insights into the transfer of silicon isotopes into the sediment record. Biogeosciences, 13(1), 147-157. https://doi.org/10.5194/bg-13-147-2016

The first δ30Si diatom data from lacustrine sediment traps are presented from Lake Baikal, Siberia. Data are compared with March surface water (upper 180 m) δ30SiDSi compositions for which a mean value of +2.28‰ ±  0.09 (95 % confidence) is derived....
