Post-glacial Sea Level rise on the Isthmus of Panama

Digital Object Identifier: 10.25573/data.11919276<br>The Isthmus of Panama is a narrow strip of land that connects the continents of North and South America and separates the Atlantic (Caribbean) and Pacific oceans. It is rich in native biodiversity, with tropical rain and cloud forests, island archipelagos, coral reefs, mangrove and estuarine ecosystems.<br><br>In this study our aim is to model how post-glacial sea-level rise changed the land- and sea-scapes of the Isthmus of Panama. This helps provide more precise historical context to better understand modern biogeographical patterns of both terrestrial and marine ecosystems on the Isthmus. In collaboration with the GIS unit at the Smithsonian Tropical Research Institute we combined bathymetric and topographic data with historical sea level data of the Western Atlantic and Tropical Eastern Pacific to produce digital elevation models, maps, and animated videos showing the changing land and sea-scapes of the Isthmus through time.<br><br>A more detailed description of the project and methods can be found here: https://storymaps.arcgis.com/stories/1d730fe1f6e443eab423a5aeea51dfb9<br>Aaron O'Dea Lab - Max TitcombSmithsonian Tropical Research Institute<br>References: <br>O’Dea A, Aguilera O, Aubry M-P, Berggren WA, Budd AF, Cione AL, Coates AG, Collins LS, Coppard SE, Cozzuol MA, de Queiroz A, Duque-Caro H, Eytan RI, Farris DW, Finnegan S, Gasparini GM, Grossman EL, Johnson KG, Keigwin LD, Knowlton N, Leigh EG, Leonard-Pingel JS, Lessios HA, Marko PB, Norris RD, Rachello-Dolmen PG, Restrepo-Moreno SA, Soibelzon E, Soibelzon L, Stallard RF, Todd JA, Vermeij GJ, Woodburne MO, Jackson JBC. 2016.

巴拿马地峡（Isthmus of Panama）是连接北美与南美大陆的狭长陆地带，分隔了大西洋（加勒比海）与太平洋。该区域拥有丰富的本土生物多样性，涵盖热带雨林、云雾林、群岛、珊瑚礁、红树林与河口生态系统。

本研究旨在模拟冰期后海平面上升如何重塑巴拿马地峡的陆地与海洋景观，为理解该区域陆地及海洋生态系统的现代生物地理格局提供更精准的历史背景。本研究与史密森尼热带研究所（Smithsonian Tropical Research Institute）的地理信息系统（Geographic Information System, GIS）部门合作，将水深测量数据、地形数据与西大西洋及热带东太平洋的历史海平面数据相结合，生成了数字高程模型、地图与动画视频，直观展示巴拿马地峡随时间变化的海陆景观。
