Mapping Hangzhou Bay's seabed complexity to refine nonlinear seismic models
Mapping Hangzhou Bay's seabed reveals how complex site conditions, seafloor topography, variable marine deposits, and bedrock undulation, can profoundly reshape nonlinear seismic response. By comparing 1D and 2D simulations, this study shows that lateral variability, not just depth, matters. At borehole ZK3, vertical peak ground acceleration ratios between models reached 2.15-2.92. Such empirical evidence underscores the value of integrated, calibrated modeling. For deeper insights into Mediterranean mesophotic systems, see our related study on carbonate production in the Sicilian Channel.
Deeper Insights: Carbonate Production in the Sicilian Channel
The Mediterranean's mesophotic zone remains a scientific gap, but new work from the Sicilian Channel is closing it. Analysis of seafloor samples from the R/V Meteor M191 expedition reveals a clear split: coralline algae thrive on Terrible Bank's shallow, irregular summit, while Nameless Bank's deeper, smoother surface hosts only dead crusts. Aphotic depths shift to cold-water corals and oysters. Topography and hydrodynamics drive this distribution, and the slow accumulation rates, paired with abandoned fishing gear, highlight how fragile these ecosystems are.
