Partnership on Sea-Level change Along Brazilian Shores (SLABS)

我们提议由来自英国约克大学、巴西圣保罗大学、帕拉帕拉联邦大学<e:1>和巴西帕拉帕尔联邦大学<e:1>的顶尖沿海和海平面科学家合作，重建过去200年来巴西沿海海平面的变化情况。这一时期非常重要，因为它涵盖了驱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。虽然以前已经对这段时间的全球海平面变化进行了估计，但它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解决这种偏见，这两种方法涉及沿海湿地沉积的沉积物和生活在岩石海岸线上的生物，我们的团队在这两种方法上都是世界领先的。我们的伙伴关系将促进伙伴之间的知识和技术技能交流，使我们能够比较和综合我们对过去海平面重建的不同方法。新的海平面记录的发展将使我们能够开始合作解决重大的科学问题，这些问题涉及海平面上升速度从自然上升到人为上升速度的转变时间，以及对全球海平面的不同贡献的演变。

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.
