Index words: Numerical modeling Lake Michigan Phytoplankton Quagga mussels The disappearance of the spring phytoplankton bloom in Lake Michigan has been attributed in some studies to the direct effect of quagga mussel filter-feeding. We applied a biophysical model to test whether the observed reduction in the spring bloom can be explained by direct effects of quagga mussel grazing. We developed...

Hydrodynamic processes over marsh topography are significantly affected by surface defects such as cuts and rills on channel berms platforms. These meter-scale features often missing in the model representation due to spatial resolution available from data sources, well incomplete grid itself. To minimize artificial hydraulic isolation numerical models, we propose implementing an effective poro...

Predicting the quality of water and air is a particular challenge for forecasting systems that support them. In order to represent the small-scale phenomena, a high-resolution model needs accurate capture of air and sea circulations, significant for forecasting environmental pollution. Data assimilation is one of the state of the art methods to be used for this purpose. Due to the importance of...

To gain a better understanding of the geochemical behavior dissolved manganese (Mn) in marginal seas with respect to distribution and exchange fluxes, more than 200 water samples were collected East China Sea (ECS) May, August, October 2013. The concentration Mn ECS ranged from 1.1 81.5 nM, gradual decrease distance shore. Seasonal varies significantly Changjiang estuary, mainly regulated by fr...

Abstract Delta evolution in the context of no sediment discharge has become a global concern, and an accretion-to-erosion conversion is occurring Yangtze estuary. This could threaten Changjiang subaqueous delta development. Sediment erodibility important indicator vulnerability. However, present future remains unclear. In this study, 37 short cores were collected from delta, critical shear stre...

Abstract. Massive floating macroalgal blooms in the ocean result many ecological consequences. Tracking their drifting pattern and predicting biomass are essential for effective marine management. In this study, a physical–ecological model, Floating Macroalgal Growth Drift Model (FMGDM), was developed. Based on tracking, replication, extinction of Lagrangian particles, FMGDM is capable determin...

Radiation stress is defined as the excess momentum caused by ocean waves, which exerts an indispensable impact on upper-layer conditions waves pass by. Previous research concentrated sea surface cooling typhoons. In this paper, we investigated effect of wave-induced radiation temperature (including (SST) and mixed-layer temperature) under typhoon conditions, well current field. The FVCOM-SWAVE ...

In this study, the effects of different bottom friction coefficient (BFC) parameterization schemes on modelling four principal tidal constituents (M 2 , S K 1 O tides) in macrotidal East China Seas were investigated by using a high-resolution model based FVCOM (Finite Volume Community Ocean Model). The applied BFC include: empirical constant (EC-BFC), sediment-dependent form (SD-BFC), and spati...

Introduction The transport of suspended sediment plays an important role in regulating erosion-accretion estuaries. Yellow River, the second longest river China, which has a large amount and contributes to River Estuary (YRE) every year. water discharge patterns lower reaches have experienced significant changes over recent decades. In particular, water-sediment regulation scheme (WSRS) Xiaolan...
