A mussel farm and a reference site were sampled on four occasions in two years, spanning the entire first year of production. Nitrate reduction rates and sediment-water fluxes of nutrients, methane, dissolved inorganic carbon and oxygen were measured in situ with benthic chamber landers. Sediment cores were collected for measurements of carbon, nitrogen and pigments and sedimentation rates were measured with sediment traps. Currents, illuminance at the seafloor and water column profiles of salinity, temperature and chlorophyll a were measured to describe the environmental characteristics of the stations. The dataset contains 8 files with the following data: - CTD profiles and chlorophyll a concentrations in the water column - Current speed and current directions - Illuminance at the sediment surface - Sedimentation rates (total, organic matter, inorganic matter) - Sediment-water fluxes of oxygen, nutrients, methane and dissolved inorganic carbon - Nitrate reduction rates in the sediment - Sedimentary pigment content (chlorophyll a, fucoxanthin, pheopigments) - Carbon and nitrogen in the sediment solid phase, porosity Full descriptions of the data can be found in the corresponding readme files accessible from the Description tab. Studiens mål var att utvärdera hur en nyligen återetablerad musselodling i As Vig, Danmark, påverkade utbytet av närsalter mellan sediment och vatten. Se utförlig beskrivning på engelska. Datasetet innehåller 8 filer med följande data: - CTD-profiler och klorofyll a-koncentrationer i vattenpelaren - Strömhastigheter och strömriktningar - Ljusmätningar vid havsbotten - Sedimentationshastigheter (total, organiskt material, oorganiskt material) - Sediment-vattenflöden av syre, närsalter, metan, och löst oorganiskt kol - Nitratreduktionshastigheter i sedimentet - Pigmentinnehåll i sedimentet (klorofyll a, fukoxantin, pheopigment) - Kol och kväve i sedimentets fasta fas, porositet Utförlig beskrivning av data finns i de tillhörande readme-filerna under fliken Beskrivning. 2017-06-26 2017-06-30 2018-07-09 2018-07-13 2018-10-22 2018-10-27 2019-02-18 2019-02-23 Denmark Danmark Numeric Text Sampling June 2017 (before settling)Sampling June 2017 (before settling) Provtagning juni 2017 (innan settling)Provtagning juni 2017 (innan settling) Sampling July 2018 (post settling)Sampling July 2018 (post settling) Provtagning juli 2018 (efter settling)Provtagning juli 2018 (efter settling) Sampling October 2018 (peak growth)Sampling October 2018 (peak growth) Provtagning oktober 2018 (max tillväxt)Provtagning oktober 2018 (max tillväxt) Sampling February 2019 (post harvest)Sampling February 2019 (post harvest) Provtagning februari 2019 (efter skörd)Provtagning februari 2019 (efter skörd) Access to data through SND.
