Riparian vegetation structure data for 15 Wessex chalkstream sites, England, UK

J. Redhead & J. Murphy
A measure of the extent and complexity of riprian vegetation upstream of chalkstream sites derived from Light Detection and Ranging (LiDAR) data for 15 discrete chalkstreams distributed along a white chalk geology extending from Dorset in the south west, through Wiltshire, to Hampshire in the north east. For each site there is an estimate of the minimum, maximum, mean and standard deviation height of vegetation along the banks for a range of distances upstream from...

Fish biomass and density data for 3 intensively studied Wessex chalkstream sites, England, UK

J.I. Jones, A. Arnold, J. Pretty, C. Duerdoth, J. Murphy, A. Hawczak, L. Scott, R. Lauridsen & W. Beaumont
Density and biomass of fish taxa from three chalkstreams in the Wessex chalk area: Nine Mile River, River Till and River Wylye. Data were collected on five occasions, between October 2012 and October 2013. The density of fish taxa at each of the three streams was estimated using benthic fish sampling and multi-pass electrofishing. The mean biomass of individuals of each taxon at each site on each occasion was then applied to the density estimates...

Temporal variation in temperature and light availability in the Hampshire Avon, United Kingdom [Macronutrient Cycling]

J.F. Murphy, A. Arnold, C.P. Duerdoth, A. Hawczak, O. Pacioglu, J.L Pretty & J. I. Jones
The dataset contains measurements of temperature (°C) and light availability (Lux) in rivers in the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. The stream sites monitored were chosen to reflect a gradient of base flow index. Data were obtained via direct, field-based measurements every 15 minutes from February 2013 to (max) December 2014 with sensors tethered to the bed of the river at each site.

Abundance, biomass and elemental composition (CNP) of consumers in the Hampshire Avon [Macronutrient Cycling]

J. I. Jones, A. Arnold, C.P. Duerdoth, A Hawczak, J.F. Murphy, O. Pacioglu, J.L. Pretty, I. A. Sanders, W.R.C. Beaumont, R.B. Lauridsen & L. Scott
The dataset contains measurements of the annual average abundance, biomass and elemental composition (C, N, P) of consumers (fish and invertebrates) in six rivers within sub-catchments of the Hampshire Avon of contrasting geology (clay, sand, chalk).

Benthic organic matter biomass data for three intensively studied Wessex chalkstream sites, England, UK

C. Duerdoth, A. Arnold, J. Pretty, J. Murphy, A. Hawczak & J.I. Jones
Ash-free dry mass (AFDM) of three distinct size fractions of organic matter (>1cm, >1mm and > 0.025mm) collected in quantitative samples of the benthic substrate determined from up to 10 replicate samples at three chalkstream sites in the Wessex chalk area (Nine Mile River, River Till and River Wylye) on each sampling occasion. Data were collected on seven occasions on the Wylye and Nine Mile River and on five occasions on the Till, between October...

Benthic biofilm chlorophyll a content and biomass data for 3 intensively studied Wessex chalkstream sites, England, UK

J. Pretty, O. Pacioglu, C Duerdoth, A. Arnold, J. Murphy, A. Hawczak & J.I. Jones
Chlorophyll-a content and ash-free dry mass of quantitative samples of the biofilm on benthic substrate from three chalkstream sites in the Wessex chalk area (Nine Mile River, River Till and River Wylye). Chlorophyll a content and biomass were determined from up to 10 replicate samples at each site on each sampling occasion. The data are presented as means with standard deviation. Data were collected on seven occasions on the Wylye and Nine Mile River and...

Riparian vegetation structure data for three intensively studied Wessex chalkstream sites, England, UK

J. Redhead & J. Murphy
A measure of the extent and complexity of riprian vegetation upstream of chalkstream sites derived from Light Detection and Ranging (LiDAR) data for three chalkstream sites within the Wessex chalk area (River Till, River Wylye and Nine Mile River). For each site there is an estimate of the minimum, maximum, mean and standard deviation height of vegetation along the banks for a range of distances upstream from the sampling location. Information on the extent and...

Cover of Land Cover Map 2007 broad habitat classes in the upstream catchment of the 20 Wessex chalkstream sites, England, UK

J. Murphy & T. Oliver
The data consists of a matrix of 12 land cover classes by 20 stream sites with the area of each land cover class given in km2. The areal coverage (km2) of each of 12 land cover classes was recorded for each of 20 chalkstream catchments in southern England. The 20 discrete chalkstream catchments are distributed along the white chalk geology extending from Dorset in the south west, through Wiltshire, to Hampshire in the north east,...
