Surface water parameters (pH, specific conductivity, salinity, nutrients, oxygen, sulfate and chloride concentrations, DOC/DIC) (Table 4)

Surface water parameters were measured in parallel to the gas measurements and soil coring for microbial analyses. Most surface water variables (pH, specific conductivity, salinity, nutrients, oxygen, sulfate and chloride concentrations, DOC/DIC) were measured in-situ using a multiparameter digital water quality meter or taken to the laboratory as water samples for further analysis. While surface water analysis was only conducted in the drainage ditch before rewetting, it was done along the entire transect after rewetting.

Nutrient concentrations from two benthic chambers and the ambient bottom water during an in-situ incubation experiment in July 2025

The dataset contains dissolved nutrient concentrations from water samples collected during a 16-day in-situ incubation experiment in the Baltic Sea (2025-07-12 to 2025-07-29). Samples were collected using an automated glass-syringe sampler deployed within two benthic chambers of a Biogeochemical Observatory (BIGO, Sommer et al., 2009) at 54° 34.432' N, 10° 10.776' E, at 22 m water depth. In one chamber, 29 g of fine calcite powder were added to the bottom water as part of an enhanced benthic calcite weathering experiment. Seven samples per chamber and from the ambient bottom water were analyzed to assess potential nutrient fluxes associated with the calcite addition and benthic biogeochemical processes.

Mesocosm experiment on the influence of heatwave on plankton

In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact of heatwaves alone, and in combination with other environmental drivers. Here, we conducted a mesocosm experiment and applied an integrated multiple driver design to assess the potential impact of heatwaves under ambient and future environmental conditions on natural coastal plankton communities. To represent future environmental conditions, temperature and pH were manipulated based on the Representative Concentration Pathway 8.5 proposed by the IPCC for 2100, and dissolved N:P ratios were increased to simulate the conditions expected in European coastal zones. Throughout the experiment, we measured abiotic conditions as well as the abundance of bacterioplankton, phytoplankton, and microzooplankton.

Water and sediment analysis from column experiments

This data set contains data from water analyses from column experiments. The water analyses included cations (sodium, potassium, calcium, magnesium, iron and manganese), anions (nitrate, chloride, sulphate, bromide and phosphate) and selected trace elements (arsenic, cobalt, nickel, vanadium and zinc). The column experiments were conducted with two different types of unconsolidated sandy sediments from aquifers in Denmark (Quaternary) and Germany (Cretaceous). In both sediments, the nitrate degradation capacity was almost exhausted. To induce denitrification, 5 mmol ethanol was added to the column experiments. This also caused a decrease in the concentration of trace elements in the water. A sequential extraction procedure was performed to determine the trace element sinks. The data set therefore also contains contents of selected elements (equal to water analyses) from the sequential extraction procedure of the sediment before and after the column tests. The results observed in the laboratory were additionally modeled with Phreeqc. The Phreeqc input data complete the data set.

Molecular and physiological regulation of adventitious root formation in Petunia cuttings in response to nutrient supply and dark exposure

The vegetative propagation of ornamental plants depends on adventitious root formation (ARF) in cuttings, which is related to economic losses in horticulture. Based on the established microarray for transcriptome studies, a biochemical and a transformation platform, Petunia will be used to investigate the molecular physiological regulation behind environmental modulation of ARF in shoot tip cuttings. The concept relies on the fact that ARF depends on establishment of the new sink in the stem base and is restricted by competition with the shoot apex for assimilate and nutrient provision. Leaves are considered as potential source organs and auxin is expected to be a key factor. Project part A follows the hypotheses, that high nitrogen supply to donor plants and dark exposure of cuttings promote ARF by enhanced nitrogen remobilization within the cutting and enhanced translocation and accumulation of the signalling molecules auxin and nitric oxide. In part B it is hypothesized that ARF is restricted by phase specific deficiency of macro- and microelements, which can be met by targeted nutrient supply to the stem base during certain developmental stages. In particular, the role of nitrate and urea in homeostasis of phytohormones is regarded. In both project parts, analysis of auxin and cytokinin levels by GC- and LC-MS/MS will be complemented by histochemical localization of auxin activity via the DR5 auxin reporter. The regulatory role of components will be verified by physiological and pharmacological treatments and in transgenic Petunia with a modified expression of candidate genes.
