Regional sea level rise has been regarded a key factor in understanding of climate change impact to coastal communities. As a vulnerable island to sea level rise and storm surges, the province of Prince Edward Island (PEI) in Canada lacks sufficient long-term island-wide historic record of sea level data. This has become a major challenge for further studies on coastal environments and climate change adaptation. To overcome this limitation, here we reconstruct a long-term hourly sea level dataset using the existing long-term records of limited permanent tide stations and short-term records of widely-distributed temporary stations. With comprehensive statistical analysis and modeling, the historical sea level records furthest between 1911 and 2023 are reconstructed with an hourly time step. This new dataset significantly extends the availability of long-term sea level data along with the shoreline of PEI, which can be used for further studies on coastal change assessment and coastal hazard adaptation in the context of climate change.

Antibiotics threaten scleractinian corals, but their accumulation patterns and physiological effects on corals in natural reefs remain unclear. This study investigated antibiotic occurrence in seawater and two coral species, Galaxea fascicularis and Pocillopora damicornis, and explored the physiological effects of bioaccumulated antibiotics in a fringing reef of the South China Sea. Nineteen antibiotic components were detected in seawater, with total antibiotic concentrations (ΣABs) ranging from 17.

As a transitional zone where rivers meet the sea, estuaries are influenced by river transport and ocean tides, resulting in complex variations in parameters such as organic matter content, pH, and sediment salinity. This paper primarily explores the vertical migration patterns of polychlorinated biphenyls (PCBs) under complex conditions, focusing on the soil sediments in the Dagu River estuary area. We designed an indoor soil column leaching experiment to investigate how soil organic matter content, pH, and salinity affect the vertical migration of PCBs in soil.

Coastal areas undergo continuous transformations, altering their geometry under the influence of external forces like tides, waves, and extreme events. Thus, monitoring the impact of extreme weather events on coastal regions is crucial to prevent potential cascading hazards. Here, we utilized time-series optical and SAR satellite data and tide records, coupled with sophisticated analytical techniques, to analyze erosion processes, sediment transport, and vertical land movement (VLM) at an embayed sandy beach (i.

Article Synopsis
- Brown algae show great potential as a nutritious food source with significant levels of protein, carbohydrates, and minerals that can help meet dietary needs.
- Analysis of eight species from India's coasts revealed high amounts of essential minerals like calcium, iron, and magnesium, which contribute to the Recommended Dietary Allowance.
- The study also found strong antioxidant properties in these algae, suggesting they may help reduce chronic disease risk and enhance overall health.
