Data from: An in situ approach for measuring biogeochemical fluxes in structurally complex benthic communities
1. The exchange of energy and nutrients are integral components of ecological functions of benthic shallow-water ecosystems and are directly dependent on in situ environmental conditions. Traditional laboratory experiments cannot account for the multidimensionality of interacting processes when assessing metabolic rates and biogeochemical fluxes of structurally complex benthic communities. Current in situ chamber systems are expensive, limited in their functionality, and the deployment is often restricted to planar habitats (e.g., sediments or seagrass meadows) only. 2. To overcome these constraints, we describe a protocol to build and use non-invasive, cost-effective, and easy to handle in situ incubation chambers that provide reproducible measurements of biogeochemical processes in simple and structurally complex benthic shallow-water communities. Photogrammetry tools account for the structural complexity of benthic communities, enabling to calculate accurate community fluxes. We tested the performance of the system in laboratory assays and various benthic habitats (i.e., algae growing on rock, coral assemblages, sediments, and seagrass meadows). In addition, we estimated community budgets of photosynthesis and respiration by corals, rock with algae, and carbonate sediments, which were subsequently compared to budgets extrapolated from conventional ex situ single-organism incubations. 3. The tests highlight the transparency (> 90% light transmission) of the chambers and minimal water exchange with the surrounding medium on most substrates. Linear dissolved oxygen fluxes in dependence to incubation time showed sufficient mixing of the water by circulation pumps and no organismal stress response. The comparison to single-organism incubations showed that ex situ measurements might overestimate community-wide net primary production and underestimate respiration and gross photosynthesis by 20 – 90%. 4. The proposed protocol overcomes the paucity of observational and manipulative studies that can be performed in in situ native habitats, thus producing widely-applicable and realistic assessments on the community level. Importantly, the tool provides a standardized approach to compare community functions across a wide range of benthic habitats. We identify multiple experimental strategies, including the manipulation of stressors/factors, and discuss how the method may be implemented in a variety of aquatic studies.

Mercury concentrations and water chemical variables measured in La Romaine hydroelectric reservoir complex in the summer of 2016, 2017 and 2018.
<p>This dataset includes chemical and physical data measured in situ in water in natural and recently dammed portions of La Romaine River watershed in Northern Quebec, Canada. Samples were collected from 2016 to 2018 in August, as well as in June 2017. For most sites, the samples were collected close to the water surface (30 cm deep) with a peristaltic pump following the clean hands dirty hands sampling protocol to avoid any contamination by trace metals. Filtered samples were collected using an in-line Whatman 0.45 µm filtration capsule attached to the tubing. For June 2017, physicochemical variables collected with a YSI multiprobe, greenhouse gas partial pressure (methane and carbon dioxide), total nutrient concentrations and dissolved metals (iron and manganese) are also included. We used this dataset to explore the distribution in time and space of various forms of mercury and pools of carbon across the dammed watershed of La Romaine and in different aquatic systems (e.g. tributaries, lakes, groundwater, river and reservoir sites). </p>
Data from: Experimental measurements of water molecule binding energies for the second and third solvation shells of [Ca(H2O)n]2+ complexes
Further understanding of the biological role of the Ca2+ ion in an aqueous environment requires quantitative measurements of both the short- and long-range interactions experienced by the ion in an aqueous medium. Here, we present experimental measurements of binding energies for water molecules occupying the second and, quite possibly, the third solvation shell surrounding a central Ca2+ ion in [Ca(H2O)n]2+ complexes. Results for these large, previously inaccessible, complexes have come from the application of finite heat bath theory to kinetic energy measurements following unimolecular decay. Even at n = 20, the results show water molecules to be more strongly bound to Ca2+ than would be expected just from the presence of an extended network of hydrogen bonds. For n > 10, there is very good agreement between the experimental binding energies and recently published density functional theory calculations. Comparisons are made with similar data recorded for [Ca(NH3)n]2+ and [Ca(CH3OH)n]2+ complexes.
