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.
区域海平面上升被视为理解气候变化对沿海社区影响的关键因素。作为一个易受海平面上升和风暴潮影响的岛屿，加拿大爱德华王子岛省（PEI）缺乏全岛范围内足够的长期海平面历史数据记录。这已成为进一步开展沿海环境和气候变化适应研究的重大挑战。为克服这一限制，我们利用现有有限的永久潮汐站长期记录和广泛分布的临时站点短期记录，重建了一个长期每小时海平面数据集。通过全面的统计分析和建模，以每小时为时间步长重建了1911年至2023年期间最远的历史海平面记录。这个新数据集显著扩展了PEI海岸线沿线长期海平面数据的可获取性，可用于在气候变化背景下进一步开展沿海变化评估和沿海灾害适应研究。
