Summary: This study developed an integrally-coupled tide-surge wave model to simulate storm tides and waves in the coastal area of Qingdao. The results showed that sea level rise and typhoon intensification had significant impacts on tides within Jiaozhou Bay, with a greater effect during the flood and ebb period. The study also revealed that the effects of sea level rise and typhoon intensification on storm tides and waves varied and were different in Jiaozhou Bay and along the open coast. Therefore, using a coupled model is crucial for estimating the potential maximum risk of storm surges and waves in the coastal area of Qingdao.

Summary: The impact of storm-induced overwashing flows on barrier islands is difficult to predict, but it can lead to erosion, barrier breaching, and inlet formation. By analyzing storm characteristics, barrier morphology, and vegetation, the intensity of overwashing flows can be estimated to assess the likelihood of barrier breaching and erosion.

Summary: Coastal lagoons can attenuate extreme water levels compared to the open sea, but their protective property is expected to decrease due to sea-level rise. This study investigates the non-linear interactions between tides, storm surges, freshwater fluxes, and sea-level rise in idealized lagoons. The results show that maximum water levels inside lagoons can rise faster than sea-level rise due to non-linear attenuation changes, while for strongly choked lagoons, the maximum water levels rise slower than sea-level rise.

Summary: This study examined the impact of climate change-induced sea-level rise on future storm-induced coastal inundation over the Massachusetts coast using a well-validated NECOFS model. The results suggest that with sustained sea-level rise, the northeastern US coast will be more vulnerable to wave runup-induced splashing/overtopping than wind-induced storm surges. The model also indicates that the responses of surge and surface waves to sea-level rise are fully nonlinear, calling for further investigation with a model including wave-current interactions.

Summary: The reciprocal relationship between barrier islands and backbarrier saltmarshes, along with the application of these natural interdependencies to coastal systems management, are discussed in this study. The case study of a marsh creation project on Cedar Island in Virginia showcases interdisciplinary engagement and the design process involved in enhancing barrier-island resilience. Ultimately, the construction of the marsh on Cedar Island aims to provide additional habitat and ecosystem benefits, slow the island migration, and inhibit island breaching, potentially enhancing storm and sea-level rise resilience.

Summary: This study investigates the resilience of gravel barriers to storm surge conditions under future sea level rise scenarios, using the Blakeney Point Barrier System in the southern North Sea. The study finds that different pre-surge barrier morphologies result in different resilience trajectories, and human interventions also affect the resilience of the landscape. However, even unmanaged barrier sections fail to demonstrate resilience to storm surge under moderate to high sea level rise.

Summary: Based on an analysis of global coastal segments, it is estimated that about 3% of the coastline requires protection to prevent coastal migration and large-scale land loss. For the remaining 97% of coastlines, an estimated land loss of 60,000 to 415,000 square kilometers and coastal migration of 17 to 72 million people is projected.

Summary: The objective of this study is to assess the impact of climate change induced rainfall, sea level rise, and urbanization on a fragile coastal aquifer. The study found that sea level rise can help prevent a decline in the groundwater level, but it also reduces the availability of freshwater and increases the possibility of seawater intrusion. Therefore, it is recommended to reduce groundwater pumping from this aquifer.

Summary: This study used aeromagnetic, satellite gravity, and ground gravity data to image the thermal and crustal structures beneath the LLL rift in southeastern Zambia. The results indicate the presence of a large magnetized body and a crust approximately 45 km thick beneath the rift. Analysis of ground gravity data suggests the presence of a large mafic body beneath the crust.

Summary: Offshore freshened groundwater (OFG) has been documented in most continental margins worldwide, predominantly within 55 km of the coast and down to a water depth of 100 m. Factors influencing OFG distribution include topography-driven flow, salinization via haline convection, and permeability contrasts. Advances in geochemical measurements and seismic reflection profiling have improved our understanding of OFG, but key knowledge gaps remain regarding its extent, function, and emplacement timing. Future research using isotopic age tracers and joint inversion of electromagnetic and seismic data is essential for addressing these gaps and assessing the potential use of OFG as an unconventional source of water.

Summary: Seafloor massive sulfide deposits are formed in remote environments, making it technically challenging and expensive to assess their size and composition through drilling. This study demonstrates the use of inverse modeling of geophysical data to enhance geological models and evaluate the resource potential of seafloor massive sulfide deposits. By utilizing magnetic and gravity data collected from the active mound at the Trans-Atlantic Geotraverse hydrothermal vent field, this study was able to determine the thickness and tonnage of the massive sulfide mound through geophysics-based, noninvasive approaches.

Summary: Seismic anisotropy produced by aligned olivine in oceanic lithosphere provides insights into mid-ocean ridge dynamics. In this study, an in situ elastic tensor for oceanic lithosphere is estimated using observational data from the NoMelt experiment. The study compares the elastic model with petrofabric data to infer crystallographic orientations and strain accumulation in the lithosphere. The results reveal significant strain accumulation in the shallow mantle and provide evidence for a specific type of olivine lattice-preferred orientation.

Summary: The Central Appalachian Anomaly (CAA) is a region beneath eastern North America with abnormal seismic velocity, seismic attenuation, and electrical conductivity structure. Through the Mid-Atlantic Geophysical Integrative Collaboration (MAGIC) experiment, new observations from teleseismic earthquakes at MAGIC stations provide insights into the structure and properties of the upper mantle in the CAA region. These observations, combined with previous estimates of attenuation and conductivity, suggest that 1%-2% partial melt is necessary to explain the anomalies in velocity, attenuation, and electrical conductivity beneath the MAGIC array.
