Metagenomic insights into surface sediment microbial community and functional composition along a water-depth gradient in a subtropic deep lake [PDF]
Frontiers in MicrobiologyDeep lakes play a critical role in global elemental cycling and serve as habitats for diverse microbial communities. However, studies on the effects of lake stratification on microbial composition and functional potential in surface sediments remain ...

Integrating water depth to predict the threshold of collapse and recovery of submerged macrophytes for lakes with large depth gradients [PDF]
Frontiers in Plant ScienceIntroductionThe nutrient threshold of collapse and recovery of submerged macrophytes have been widely reported for shallow lakes. However, understanding the threshold variation for lakes with water depth (Z) gradients remains limited.MethodsIn this study,

Particle Filtering for Source Depth and Water Depth Joint Tracking in Shallow Water
Journal of Marine Science and Engineering, 2023 Environmental mismatch degrades the performance of source localization and tracking methods in shallow water. One solution is to estimate source parameters and the key environmental parameters simultaneously from the acoustic data.

Bill Length of Non‐breeding Shorebirds Influences the Water Depth Preferences for Foraging in the West Coast of India [PDF]
Ecology and EvolutionBody size, bill length and shape determine foraging techniques, habitat selection and diet among shorebirds. In this study, water depth preferences of different shorebirds with different bill sizes in various habitats including mudflats, mangroves at ...

Water depth modulates the species richness–biomass relationship in submerged macrophytes
Frontiers in Environmental Science, 2023 The effect of biodiversity on ecosystem productivity has been a controversial issue in ecological research. The species richness–productivity relationship is highly variable in natural ecosystems, with a positive relationship being one of the most ...

Assessment of the Offshore Wind Energy Potential in the Romanian Exclusive Economic Zone
Journal of Marine Science and Engineering, 2021 The European offshore wind market is continuously expanding. This means that, together with significant technological developments, new coastal environments should be considered for the implementation of the wind farms, as is the case of the Black Sea ...

Spatially Quasi-Periodic Water Waves of Infinite Depth [PDF]
Journal of Nonlinear Science, 2021 AbstractWe formulate the two-dimensional gravity-capillary water wave equations in a spatially quasi-periodic setting and present a numerical study of solutions of the initial value problem. We propose a Fourier pseudo-spectral discretization of the equations of motion in which one-dimensional quasi-periodic functions are represented by two-dimensional
