Our proposed collaborative partnership between leading coastal and sea-level scientists from the University of York in the UK and the University of São Paulo, the Federal University of Paraná, and the Federal University of Pará in Brazil seeks to reconstruct how sea levels have changed along the Brazilian coast over the last 200 years. This period is highly significant as it covers the critical time during which the natural processes that had been driving sea-level change gave way to the dominance of human activities. While estimates of global sea-level change during this time have been made before, they almost exclusively rely on data from the Northern Hemisphere. We will contribute to addressing this bias by reconstructing sea levels using two approaches involving sediments deposited in coastal wetlands and organisms that live attached to rocky shorelines, approaches in which the team are world leaders. Our partnership will facilitate exchange of knowledge and technical skills between the partners, enabling us to compare and integrate our differing approaches to past sea-level reconstruction. The development of new sea-level records will allow us to begin to collaboratively address major scientific questions concerning the timing of the transition from natural to anthropogenically elevated rates of sea-level rise and the evolution of the different contributions to global sea level.

我们计划在英国约克大学、S圣保罗大学、巴拉那联邦大学和巴西帕拉联邦大学的一流沿海和海平面科学家之间建立合作伙伴关系，旨在重建巴西海岸海平面在过去200年中的变化。这一时期意义重大，因为它涵盖了推动海平面变化的自然过程让位于人类活动主导的关键时期。虽然对这段时间内全球海平面变化的估计以前也有过，但他们几乎完全依赖于北半球的数据。我们将通过使用两种方法重建海平面来帮助解决这种偏见，这两种方法涉及沿海湿地中沉积的沉积物和生活在岩石海岸线上的生物，该小组在这两种方法中处于世界领先地位。我们的伙伴关系将促进伙伴之间的知识和技术技能交流，使我们能够比较和整合我们对过去海平面重建的不同方法。开发新的海平面记录将使我们能够开始协作处理重大科学问题，这些问题涉及海平面上升速度从自然上升向人为升高转变的时机，以及对全球海平面的不同贡献的演变。
