A comprehensive database of paleoclimate records is needed to place recent warming into the longer-term context natural climate variability. We present a global compilation quality-controlled, published, temperature-sensitive proxy extending back 12,000 years through Holocene. Data were compiled from 679 sites where time series cover at least 4000 years, are resolved sub-millennial scale (median spacing 400 or finer) and have one age control point every 3000 with cut-off values slackened in...
Student engagement is intrinsically linked to two important metrics in learning: student satisfaction and the quality of experience. One ways that can be influenced through careful curriculum design. Using knowledge many students are ‘assessment-driven’, a low-stakes continuous weekly summative e-assessment was introduced module. The impact this had on measured by studying activity within module virtual learning environment. It found introduction e-assessments led significant increase...
Student engagement is an important issue in higher education, and related to the quality of student experience. Increasing one way enhancing at a education institution. An institution able influence number ways, being through curriculum design. The use low-stakes continuous weekly summative e-assessment had positive on optional level 5 (second year) undergraduate geography module. Students considered their increased was direct consequence this assessment method. It also found that students...
Background: The relative frequency of wind- and animal-pollinated plants a non-randomly distributed across the globe numerous hypotheses have been raised for greater occurrence wind pollination in some habitats towards higher latitudes. To date, however, there has no comprehensive global investigation these hypotheses.Aims: Investigating range role biotic abiotic factors as determinants variation animal vs. pollination.Methods: We analysed 67 plant communities ranging from 70º north to 34º...
Early-Holocene warming in Iceland caused rapid glacial ice melt which led to exposed landscapes on soils developed and floras quickly established. Our chironomid-based records from northern suggest temperatures were up 2—2.5°C warmer than present throughout the first two millennia post deglaciation (~10 500 8500 cal. BP) while sedimentary isotopic data indicate development of within local environment this period before catchment conditions started stabilise around 8400 BP. The trend over was...
Abstract Mitigation of diffuse water pollution from agriculture is concern in the United Kingdom, so that freshwater quality can be improved line with environmental objectives. Targeted on‐farm mitigation necessary for controlling sources to rivers; a positive impact must also delivered at subcatchment and catchment scales before good ecological status achieved. A farm on River Sem Hampshire Avon Demonstration Test Catchment was selected monitoring due its degraded farmyard, track, drainage...
The aim of this research was to create a decadal-scale terrestrial quantitative palaeoclimate record for NW Iceland from lake sediments the last millennium. Geochemical, stable isotope and chironomid reconstructions were obtained sequence constrained by tephra deposits on Snæfellsnes peninsula, western Iceland. Obtaining proved problematic, but qualitative showed clear trends associated with past summer temperatures, sedimentological records provided evidence changes in precipitation,...
ABSTRACT A multiproxy Lateglacial environmental record is presented for a ca. 3.5‐m lacustrine sequence retrieved from small basin (ca. 2 km ) at Thomastown Bog in County Meath, Ireland. Sediment chemistry, pollen, chironomid and stable isotope data provide detailed picture of catchment lake system changes the end last glacial (GS‐2a) to early Holocene that correspond closely existing local regional models climate change. Concomitant adjustments independent proxy records are matched NGRIP...
This study explored the disposal strategies of menstrual sanitary products through in-depth semi-structured interviews with women aged 18–30 years. There have been many educational campaigns to improve solid waste disposal, but inappropriate and blockages are still a major problem for water industry. While quantitative studies exploring self-reporting flushing norms conducted, there is evidence suggest that these results may not take into account complex set socio-cultural factors associated...
Abstract. Subfossil chironomids in short cores from two lakes western Iceland were analysed and a chironomidmean July air temperature transfer function applied to produce chironomid-inferred reconstructions for the recent past. These compared with local meteorological data order evaluate technique Iceland. The chironomidinferred showed similar patterns magnitudes of change those recorded instrumental data, but chironomid slightly underpredicted observed temperatures. This suggests that are...
Abstract. The River Rother, West Sussex, is suffering from excess sediment which smothering the river bed gravels. This thought to be exacerbating issues of pollution and degradation ecosystems. project aims identify severity, extent, possible causes potential mitigation options available reduce these pressures on river. Data have been collected ten sites investigate amount stored in gravels cores obtained four small reservoirs establish rates sedimentation contribute construction a temporal...
Glacial geomorphological mapping from the southern margin of Skálafellsjökull, southeast Iceland, depicts a topographically diverse mountainside, influencing glacier dynamics, landform formation and retreat since Little Ice Age maximum in ∼1890. The glacial landforms present are typical Icelandic temperate glaciers, comprising recessional push moraines, including sawtooth associated fluting. Study area A demonstrates an abandoned lobe confined by steep V-shaped topography, displaying...
De Geer moraines (DGMs) have the potential to generate very high-resolution spatial and temporal ice margin reconstructions (~annual in contrast 100-500 years, current state-of-the-art). Existing studies suggest that DGMs likely form annually a sub-aqueous, ice-marginal environment whereby basal sediments are advected deposited at grounding-line during seasonal advances. However, there also been suggestions of crevasse-fill origin challenges this regularity. Whilst spatiotemporal properties...
Abstract Field courses are widely regarded as integral to geography degree programmes, providing students with opportunities for experiential learning, often in unfamiliar international environments. Yet, this key area of pedagogy appears increasingly unsustainable and complex Higher Education Institutions (HEIs) within the context urgent need decarbonisation, increasing financial costs, institutional challenges comprehensively embedding necessary Equality, Diversity Inclusion (EDI)...
De Geer moraines (DGMs) may act as valuable ice margin indicators; however, to date, their variable mode of formation has presented challenges for this utility. Morphometric investigations provide useful insights into processes, which can be developed using sedimentological and geophysical methods. Here we present ground penetrating radar (GPR) data DGMs located in southwest Finland. Individual lithofacies were identified interpreted sediment architectural elements. These correlated with...
