Data from: Benthos response to nutrient enrichment and functional consequences in coastal ecosystems

Sample were collected in an intertidal mudflat in Isle-Verte Bay (48° 2’ 36.76” N; 69° 21’ 3.736” W, St. Lawrence estuary, QC, Canada) in vegetated areas (Veg) and ice made-tidal pools (UnV).

They were then exposed, in a well-controlled laboratory experiment, to three intensities of nutrient enrichment (N0, N1 and N2) during 30 days. Description of the dataset Data are organized in five tabular data files (.txt files; separator = tab, decimal = ., missing data = NA). Please refer to related publication for experimental design and analytical methods Sediment_characteristics.txt This file includes median sediment grain size (D50; µm), sediment porosity (volume ratio), Sediment organic matter (SOM; %Loss on ignition), Chlorophyll a content (Chl a; µg g-1), phaeopigments (µg g-1), Seagrass leaf biomasse (g) and Seagrass leaf elongation (cm day-1) Macrofauna_density.txt This file includes densities (individuals m-2) of sampled macrofaunal species Bioturbation.txt This files includes bioturbation metrics such as maximum penetration depth of luminophores (MPD; cm), Biodiffusion coefficient (Db; cm2 y-1) and porewater exchange rate (Q; mL m-2 h-1) Oxygen_dynamics.txt This file includes diffusive oxygen uptake (J; mmol m-2 d-1) and oxygen penetration depth (Z; µm) Nutrient_profiles.txt This file includes porewater nutrient (NH4+, NO3- and PO43-; µM) profiles within the sediment column (depth; cm) Benthic_fluxes.txt This file includes oxygen (TOU) and nutrients ((NH4+, NO3-) benthic fluxes (mmol m-2 h-1)
