Land subsidence monitoring and analysis in Qingdao, China using time series InSAR combining PS and DS

Geomatics Natural Hazards and Risk, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 6, 2025

With the accelerated urbanization process in Qingdao, urban land subsidence has damaged infrastructure and hindered sustainable development. To prevent disasters caused by subsidence, large-scale, long-term monitoring, mechanism analysis, risk assessment are essential. This study proposes an improved time series Interferometric Synthetic Aperture Radar (InSAR) method, extracting Permanent Scatterers (PS) Distributed (DS) based on a two-layer network. Using Sentinel-1 dataset, Qingdao's from 2019 to 2024 was monitored. The results were validated using multi-source data, comprehensive analysis of spatiotemporal distribution causes conducted ,alongside matrix Hurst index. Results show that combining PS DS increases measurement density. From 2024, generally stable, with mainly along Jiaozhou Bay , reaching maximum rate −84 mm/year due reclamation. Two mechanisms identified at Bridge: linear seasonal cyclic subsidence. revealed most sampling points seven areas remain dangerous state. systematically investigated evaluated stability, provided insights solutions for prevention control.

Freshwater faces a warmer and saltier future from headwaters to coasts: climate risks, saltwater intrusion, and biogeochemical chain reactions

Biogeochemistry, Journal Year: 2025, Volume and Issue: 168(2)

Published: March 10, 2025

Abstract Alongside global climate change, many freshwater ecosystems are experiencing substantial shifts in the concentrations and compositions of salt ions coming from both land sea. We synthesize a risk framework for anticipating how change increasing pollution saltwater intrusion will trigger chain reactions extending headwaters to tidal waters. Salt ‘chain reactions,’ where chemical products one biogeochemical reaction influence subsequent ecosystem responses.

Forecasting climate and human alterations to coastal and estuarine dissolved organic matter

Limnology and Oceanography Letters, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 25, 2025

Abstract River networks serve as conduits for dissolved organic matter (DOM) and carbon (DOC) from inland to coastal waters. Human activities climate change are altering DOM sources, causing hydrological biogeochemical shifts that impact DOC concentrations changing the transport transformation of DOC. Here, we synthesize current knowledge concentrations, associated changes during along inland‐to‐coastal gradients, focusing on impacts estuarine We project continued land‐use changes, management, sea‐level rise will result in more microbial labile DOM, higher an overall decoupling quantity quality. Understanding how these vary among river is essential forecast water quality, ecosystem health, global cycling.

Gulf Stream Near Cape Hatteras Modulates Sea Level Variability Along the Southeastern Coast of North America

Geophysical Research Letters, Journal Year: 2025, Volume and Issue: 52(7)

Published: April 1, 2025

Abstract Studies suggest a strong link between low‐frequency sea level variability in the South Atlantic Bight (SAB) and open ocean dynamics. However, mechanisms driving this connection remain unclear. By analyzing high‐resolution, three‐dimensional baroclinic reanalysis, we identify pathway that links dynamics to SAB coastal through shelf edge near Cape Hatteras. Gulf Stream meanders region induce fluctuations propagate along entire shelf. Using an idealized barotropic model, further demonstrate topographic waves mediate propagation of signal onto Moreover, is driven by zonal wind stress Northwest Atlantic, which likely modulated North Oscillation. These findings offer new insights into regional prediction contribute broader climate research efforts.
