title: Optical properties of porewater dissolved organic matter and bulk characteristics of bottom waters and sediments of the Baltic Sea

description: Pore water dissolved organic matter fluorescence (FDOM) parameters were collected by Rhizon samplers from the water 2 cm above the sediment and the top 10 cm of the sediment cores, which were recovered using GeMax sampler, parameters (pH, Salinity, Oxygen) measured using deepening probes in the bottom water 2cm above the sediment surface. Porosity and loss on ignition index were evaluated via slicing the top 10 cm of the sediment cores recovered by GeMax sediment corer at 2 cm intervals. These samples were collected between 2020 and 2021 during cruises onboard RV Oceania (Institute of Oceanology of the Polish Academy of Sciences), which took place in spring, autumn, and winter, to the Central and Southern Baltic Sea, i.e., Eastern Gotland Basin, Bornholm Basin, and Gdansk Basin. The pore water fluorescence was collected to characterize dissolved organic matter quality within sediments. Loss on ignition index was used to evaluate the organic matter content within sediments. Bottom water parameters and porosity were collected for auxiliary station characterization.

title: Molecular weight of dissolved organic matter in sediments of the Baltic Sea

description: Pore water dissolved organic matter average weighted apparent molecular weight (AMW) and abundancies of molecular weight (MW) fractions obtained by Gaussian decomposition of size exclusion chromatograms from pore water samples collected using Rhizon samplers from the water 2 cm above the water-sediment interface and the top 10 cm of the sediment cores at 2cm interval. The sediment cores were recovered using a GeMax sampler. These samples were collected between 2020 and 2021 during cruises onboard RV Oceania (Institute of Oceanology of the Polish Academy of Sciences), which took place in spring, autumn, and winter, to the Central and Southern Baltic Sea, i.e., Eastern Gotland Basin, Bornholm Basin, and Gdansk Basin. The pore water dissolved organic matter molecular weight was used for further evaluation of the sediment flux of dissolved organic carbon. The molecular weight fractionation was used for characterizing pore-water dissolved organic matter in the Baltic Sea sediments. AMW (Da) - averaged weighted apparent molecular weight. Molecular weight was measured by size exclusion chromatography (SEC) using a Shimadzu Nexera X2 UFLC system equipped with a TSKgel SuperAWM-H column. Dissolved organic matter was eluted with 0.15 M ammonium acetate (pH 7), and two sequential detectors were used. Absorbance was measured between 240 and 600 nm at 2 nm intervals using a Shimadzu SPD-M30. Retention times were converted to apparent molecular size based on a calibration curve using polystyrene sulfonate standards. For AMW, a spectral slope value between 275 and 295 nm (S275-295) was evaluated for each absorbance spectrum using log-transformed linear regression during SEC analyses at every second of retention time. The retention time was then converted into apparent MW after calibration and weighted average molecular weight (MW) was inferred. Abundances of low molecular weight (LMW), medium molecular weight (MMW), and high molecular weight (HMW) in the Dalton*Absorbance Unit were calculated by fractionation of MW chromatograms using absorption at 350nm signal. For this, each SEC-absorbtion chromatogram was fitted with three Gaussian peaks using "peakfit" function in MATLAB (MathWorks®). The three peaks were referenced as LMW for peaks centered at retention times equivalent to MW ~100-500 Da, MMW for the peaks centered at retention times equivalent to MW of ~500Da -1 kDa, and HMW for peaks centered at retention times equivalent to MW larger than 1 kDa for further analyses. The areas under the Gaussian peaks were referred to as abundancies of corresponding MW fractions.

title: Dissolved organic carbon and dissolved inorganic nutrients in the pore waters of the Baltic Sea

description: Pore water dissolved organic carbon (DOC) and inorganic nutrients were collected by Rhizon samplers from the water 2 cm above the sediment and the top 10 cm of the sediment cores with a 2 cm interval. The sediment cores were recovered using a GeMax sampler. These samples were collected between 2020 and 2021 during cruises onboard RV Oceania (Institute of Oceanology of the Polish Academy of Sciences), which took place in spring, autumn, and winter, to the Central and Southern Baltic Sea, i.e., Eastern Gotland Basin, Bornholm Basin, and Gdansk Basin. The pore-water DOC (µmol/L) - dissolved organic carbon concentrations in µmol per LiterDOC samples were analyzed by high-temperature catalytic oxidation (Pt) (680 °C) oxidation using a total organic carbon analyzer (TOC-L, Shimadzu) equipped with a nondispersive infrared detector. The quality of the results was confirmed by daily analyses of certified reference material (CRM) (North Atlantic water) obtained from the Hansell Laboratory, University of Miami (recovery: 98.9%, RSD: 0.9%).; \nAmmonium (NH^(+)4 (µmol/L)), nitrate and nitrite mixture (NO^(-)x (µmol/L)), and phosphate (PO^(3-)4 (µmol/L)) concentrations analyses were performed after Hansen and Koroleff (2007) using the SEAL AA500 AutoAnalyzer (Seal Analytical). The quality of the measurements was controlled by repeated measurements of two different CRMs, QC3179, Sigma Aldrich, and HAMIL-20.2, Environment Canada. Therefore, the detection limits of 0.33 µmol L-1 for NO^(-)x, 0.27 µmol L-1 for NH^(+)4 and 0.1 µmol L-1 for PO^(3-)4 were determined with an accuracy of 98.8%, 98.6%, 98.8% and 99.0% and a precision of 0.7%, 1.1%, and 0.5% for NO^(-)x, NH^(+)4 and PO^(3-)4, respectively. b.d.- below detection.

title: Sediment Dissolved Organic Carbon Release in the Baltic Sea

description: Dissolved organic carbon (DOC) flux evaluated by Fick's first law of diffusion. The values were evaluated using the pore water dissolved organic matter, average weighted apparent molecular weight of DOM measured in samples collected by Rhizon samplers from the water 2 cm above the sediment and the top 10 cm of the sediment cores at 2 cm intervals. The porosity was evaluated as sediment water content was obtained from sediment samples collected via slicing of the upper 10 cm of sediment cores over 2 cm intervals. The sediment cores were recovered using GeMax sediment corer. These samples were collected between 2020 and 2021 during cruises onboard RV Oceania (Institute of Oceanology of the Polish Academy of Sciences), which took place in spring, autumn, and winter, to the Central and Southern Baltic Sea, i.e., Eastern Gotland Basin, Bornholm Basin, and Gdansk Basin. The reported DOC sediment fluxes are the final product.
description: DOC diffusive flux calculations, DOC concentrations in the near-sediment waters and pore water DOC concentrations, porosity and average weighted molecular weight (AMW) of the dissolved organic matter from the near bottom waters (~2cm above sediment surface) and the uppermost slice of the sediment core (0 to 2 cm depth) were used. The fluxes (JDOC) were evaluated according to the Fick's first law of diffusion: J_DOC=-ϕ×Ds×ⅆC/ⅆz; where ϕ is the sediment porosity, ⅆC/ⅆz is the gradient of DOC concentration over the investigated depth interval (0 to 2 cm) and Ds is a bulk sediment diffusion coefficient. Ds was previously demonstrated to be dependent on the sediment formation resistivity factor (F). Ds was calculated using F which equals ϕ^(−3). AMW was calculated from Size Exclusion chromatograms for each sample, and the AMW evaluated for the pore water at 0-2 cm at each station was incorporated into Ds:\nDs=1.1×10^(-3) AMW^(-0.81)/ϕF.

title: Spectral reflectance measurements of dry and wet plastic materials, asphalt, concrete klinker from SWIR-1751 nm to SWIR-2500 nm around Spuikom, Belgium

description: Lambertian-equivalent hyperspectral reflectance measurements were completed on 26 June 2019 on the east shore of the Spuikom lagoon in Ostend, Belgium between 10:00 – 12:00 local time (UTC + 2 hrs) under natural sunlight. An ASD spectroradiometer covering the wavelength ranges 350 nm to 2500 nm was operated in reflectance mode and was fitted with an 8° field-of-view lens. Relative reflectance was derived by white referencing using the 99% white Lambertian plaque, the calibration reflectance factor of the panel is also provided with this dataset. Each relative reflectance measurement over a sample was taken as an average of 30 continuous scans. The measurement sequence involved a white reference measurement followed by a sequence of 10 random point sampling of the sample and then another white reference. We did concrete bricks near the dry land target that had a pattern of faded red and gray bricks. We did first 10 over gray and the second 10 over red bricks. We measured over the asphalt in the road next to the sail club and adjacent to the dry target. The plastic targets included small boats, polyethylene terephthalate (PET) water bottles and low-density polyethylene (LDPE) PMD plastic bags.
