Effects of filtration timing and pore size on measured nutrient concentrations in environmental water samples

open access: yesLimnology and Oceanography: Methods, Volume 21, Issue 1, Page 1-12, January 2023., 2023
Abstract Nutrient monitoring is important for informing management decisions to mitigate eutrophication in aquatic systems. Many nutrient monitoring programs use filter pore sizes that allow microorganisms to pass into samples and/or wait extended times between sample collection and filtration/preservation, allowing microbial processes to alter ...

Origin and fluxes of atmospheric REE entering an ombrotrophic peat bog in Black Forest (SW Germany): Evidence from snow, lichens and mosses [PDF]

open access: yes, 2006
The fate of the Rare Earth Elements (REE) were investigated in different types of archives of atmospheric deposition in the Black Forest, Southern Germany: (1) a 70 cm snow pack collected on the domed part of a raised bog and representing 2 months of ...

Comparing UAS LiDAR and Structure-from-Motion Photogrammetry for Peatland Mapping and Virtual Reality (VR) Visualization

open access: yesDrones, 2021
The mapping of peatland microtopography (e.g., hummocks and hollows) is key for understanding and modeling complex hydrological and biochemical processes. Here we compare unmanned aerial system (UAS) derived structure-from-motion (SfM) photogrammetry and

Bacterial Community Composition and Dynamics Spanning Five Years in Freshwater Bog Lakes

open access: yesMsphere, 2017
Lakes are excellent systems for investigating bacterial community dynamics because they have clear boundaries and strong environmental gradients. The results of our research demonstrate that bacterial community composition varies by year, a finding which

Simulation of boil-off gas recovery and fuel gas optimization for increasing liquefied natural gas production

open access: yesEnergy Reports, 2023
In a natural gas liquefaction plant, boil-off gas (BOG) is generated in both liquefaction and loading processes. During the holding mode (no loading operation), the fuel gas supply, including the BOG generated in the liquefaction process, is less than ...

Regional patterns and controlling factors in plant species composition and diversity in Canadian lowland coastal bogs and laggs [PDF]

open access: yesMires and Peat, 2016
Inventories of natural assemblages of plant species are critical when planning ecological restoration of bogs. However, little is known about the regional variation in plant communities at the margins (laggs) of bogs, even though they are an integral ...

Geographic object‐based image analysis (GEOBIA) of the distribution and characteristics of aeolian sand dunes in Arctic Sweden

open access: yesPermafrost and Periglacial Processes, Volume 34, Issue 1, Page 22-36, January/March 2023., 2023
Abstract Current climate change in the Arctic is unprecedented in the instrumental record, with profound consequences for the environment and landscape. In Arctic Sweden, aeolian sand dunes have been impacted by climatic changes since their initial formation after the retreat of the last glacial ice sheet.
