Mine water characterisation and monitoring borehole GGA05, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA05 at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Mine water borehole GGA05 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Main mine working void and overlying sandstone roof. The mine working is a water-filled void and initial hydrogeological indications from the test pumping are of a very high yielding borehole. Borehole GGA05 has ERT and DTS cables installed between the borehole casing and the rock wall and has a hydrogeological data logger installed within the borehole

Borehole GGA02, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA02 at the UK Geoenergy Observatory in Glasgow, as well as summarising an initial geological interpretation. Mine water borehole GGA02 at the UK Geoenergy Observatory in Glasgow encountered the Glasgow Upper and Glasgow Ell mine workings and was screened across an interval interpreted as a completely collapsed Glasgow Main mine working and overlying sandstone roof. Unfortunately, grout entered the inside of the casing in the final stages of borehole construction, cementing up the screened section and resulting in GGA02 being repurposed as a cased, sensor testing borehole. New sensors can be tested inside the uPVC casing to 67.2 m drilled depth. Hydrogeological testing of GGA02 was not possible. Borehole GGA02 has a number of types of sensor cabling installed. Fibre-optic DTS cable is installed between the bedrock uPVC borehole casing and the rock wall with capability to work in passive (monitoring) mode to 72.65 m drilled depth. Fibre-optic cabling is also installed on the outside of the steel superficial deposits casing with the ability for use in active or passive mode. Electrical resistivity tomography cable with the deepest sensor placed at 85.58 m drilled depth is available for cross-borehole monitoring and imaging with the adjacent borehole GGA01

Mine water characterisation and monitoring borehole GGA04, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA04 at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Mine water borehole GGA04 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Upper coal and overlying sandstone roof. The borehole was drilled within an area of stoop (pillar) and room mine workings and is interpreted to have hit a coal pillar or partially collapsed pillar and a possibly fractured sandstone roof. It can be used for characterising and monitoring a fractured rock mass within a mine working area. Initial hydrogeological indications from the test pumping indicate that borehole GGA04 is high yielding. Borehole GGA04 has ERT and DTS cables installed between the borehole casing and the rock wall and has a hydrogeological data logger installed within the borehole

A stationary free boundary problem modeling electrostatic MEMS

A free boundary problem describing small deformations in a membrane based model of electrostatically actuated MEMS is investigated. The existence of stationary solutions is established for small voltage values. A justification of the widely studied narrow-gap model is given by showing that steady state solutions of the free boundary problem converge toward stationary solutions of the narrow-gap model when the aspect ratio of the device tends to zero

Mine water characterisation and monitoring borehole GGA01, UK Geoenergy Observatory, Glasgow.

This report and accompanying data release describe the ‘as-built’ borehole GGA01 at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Mine water borehole GGA01 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Upper mine working and overlying sandstone roof. The mine working is interpreted to be filled with a loosely packed mine waste. Hydrogeological evidence from test pumping indicates that the borehole is very high yielding. Borehole GGA01 has ERT and DTS cables installed between the borehole casing and the rock wall and has a hydrogeological data logger installed within the borehole

Environmental baseline characterisation and monitoring borehole GGA06r, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA06r at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Environmental baseline characterisation and monitoring borehole GGA06r at the UK Geoenergy Observatory in Glasgow is screened across a coarse sand and gravel in the superficial deposits. The borehole has proved to be low yielding on initial hydrogeological testing and has a hydrogeological data logger installed

Mine water characterisation and monitoring borehole GGA08, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA08 at the UK Geoenergy Observatory in Glasgow. They also describe initial hydrogeological testing completed after borehole construction and provide an initial geological interpretation. Mine water characterisation and monitoring borehole GGA08 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Main mine working and overlying sandstone roof. The mine working is interpreted as a roadway with a void, mine waste and wood encountered. Initial hydrogeological indications from the test pumping suggest borehole GGA08 is very high yielding. Borehole GGA08 has ERT and DTS cables installed between the borehole casing and the surrounding rock, and a hydrogeological data logger installed within the borehole

Environmental baseline characterisation and monitoring borehole GGB05, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGB05 at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Environmental characterisation and monitoring baseline borehole GGB05 at the UK Geoenergy Observatory in Glasgow is screened across a sandstone beneath rockhead, and thought to be around 5 m above recorded stoop and room mine workings in the Glasgow Upper coal. Initial hydrogeological indications from the test pumping suggest that borehole GGB05 is moderately yielding. There is a hydrogeological data logger installed in the borehole

Environmental baseline characterisation and monitoring borehole GGB04, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGB04 at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Environmental baseline characterisation and monitoring borehole GGB04 at the UK Geoenergy Observatory in Glasgow is screened across a sand and gravel unit in the upper part of the superficial deposits. Hydrogeological evidence from test pumping indicates that the borehole is very low yielding. There is a hydrogeological data logger installed in the borehole

Genomic analysis of Kazachstania aerobia and Kazachstania servazzii reveals duplication of genes related to acetate ester production

Kazachstania aerobia and Kazachstania servazzii can affect wine aroma by increasing acetate ester concentrations, most remarkably phenylethyl acetate and isoamyl acetate. The genetic basis of this is unknown, there being little to no sequence data available on the genome architecture. We report for the first time the near-complete genome sequence of the two species using long-read (PacBio) sequencing (K. aerobia 20 contigs, one scaffold; and K. servazzii 22 contigs, one scaffold). The annotated genomes of K. aerobia (12.5Mb) and K. servazzii (12.3Mb) were compared to Saccharomyces cerevisiae genomes (laboratory strain S288C and wine strain EC1118). Whilst a comparison of the two Kazachstania spp. genomes revealed few differences between them, divergence was evident in relation to the genes involved in ester biosynthesis, for which gene duplications or absences were apparent. The annotations of these genomes are valuable resources for future research into the evolutionary biology of Kazachstania and other yeast species (comparative genomics) as well as understanding the metabolic processes associated with alcoholic fermentation and the production of secondary ‘aromatic’ metabolites (transcriptomics, proteomics and metabolomics).Mandy Man-Hsi Lin, Michelle E.
