Description:

General description

This dataset include the data collected during two experiments carried out in May and August 2019 to investigate the mechanisms involved in the benthic response to nutrient enrichment 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 (D_b; 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 PO₄^3-; 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)
