Biogeochemical, hydro- and hydro-chemical and ecological data collected from terrestrial and riverine sites from across mixed geologies in the Hampshire Avon collected by the role of lateral exchange in modulating the seaward flux of C, N, P project

This data series includes continuous monitoring data for both hydrological and hydrochemical variables at four instrumented riverine sites and continuous CO2 exchange data for three instrumented terrestrial sites. In addition to these continuous monitoring data sets there are data sets from intensive campaigns at six sites aimed at characterising the cycling of both carbon and nitrogen in both riverbed sediments and terrestrial soils with additional data on the microbiology driving some of the key processes in the cycling of carbon and nitrogen. For the riverine sites there are also ecological macroinvertebrate and fish data, including abundance and their elemental composition.

This data series was collected as part of the Lateral Exchange consortium project (NE/J012106/1), under the NERC Macronutrient Cycles programme. Our overall aim was to capture how the processing of the life supporting elements (C,N,P) is governed by the different pathways by which macronutrients are travelling from grassland fields through river systems and out to the coast in different parts of the landscape - including on clay, sand and chalk geologies. An overall summary of our aims, approach and key findings can be found in the Supporting Documentation.

The consortium was led by Prof. Mark Trimmer (Queen Mary, University of London) along with co-investigators at the Universities of Essex, York, Lancaster and Imperial College London and ran from October 2012 to December 2015.
