BOSCORF has just taken delivery of a Geotek Single Track Core Imaging System (MSCL-CIS). This will allow routine and rapid acquisition of high-resolution core imagery soon after core splitting before colour changes can occur (e.g. through oxidation) to provide very high-quality archival records. It will provide precise depth-registered images that can be correlated with other datasets or used when describing core; and visiting researchers and students will be able to obtain their own high-... |

As the Arctic is warming rapidly, vegetation expands northwards, potentially leading to increasing nutrient inputs in lakes. This can result in increased storage or release of carbon depending on lake biology and regional geography. Lakes and the Arctic Carbon Cycle (LACC) is a NERC-funded project that aims to improve our understanding of the relationships between climate, vegetation, and arctic lakes and their role in the carbon cycle.
LACC will investigate lakes in arctic Alaska... |

This week Elaine McPherson and Charlotte Lloyd (M.Sc. students) from Teesside University have been carrying out a series of flume experiments in collaboration with Dr Charlie Thompson (University of Southampton). They are investigating the effect of sediment flow on the surface topography of submerged bones.
The experimental phase involves the exposure of submerged bone samples to sediment of varying grain sizes using an annular flume. Bones were submerged over a 72 hour period with... |

The lacustrine sediments at Marks Tey, Essex, represent a scientifically important palaeoclimatic sequence as they preserve the most complete record of Marine Isotope Stage 11 (interglacial, 424,000-374,000 years ago) in the UK, which is considered one of the best climatic analogues for the Holocene. Gareth Tye, a Ph.D. student from Royal Holloway, University of London, is currently running Marks Tey varved lake sediments on the BOSCORF ITRAX. The early part of the record... |
