Reconstructing Deep-Ocean Circulation During Cenozoic Climate Transitions From The Marine Sediment Record, Brian Romans
Reconstructing Deep-Ocean Circulation During Cenozoic Climate Transitions From The Marine Sediment Record, Brian Romans
Sustainability Seminar Series
Ocean circulation plays a critical role in the Earth’s climate system through the storage and transfer of heat and carbon dioxide. The North Atlantic and Southern Ocean are of particular interest because these are regions where deep-water components of global circulation develop. Dr. Romans uses the deep-sea sedimentary record to reconstruct past ocean circulation and its relationship to past climatic and tectonic conditions. He integrates information from a broad range of spatial and temporal scales, from seismic-reflection data that reveals regional sedimentation patterns to high resolution records based on quantitative grain-size analysis from cores. Dr. Romans will present research from …
The Role Of Island-Marsh Couplings In The Long-Term Sustainability Barrier Islands In The Face Of Accelerated Sea-Level Rise, Christopher Hein
The Role Of Island-Marsh Couplings In The Long-Term Sustainability Barrier Islands In The Face Of Accelerated Sea-Level Rise, Christopher Hein
Sustainability Seminar Series
Barrier islands are one of the most ubiquitous features of the coast . . . at least here along the US East Coast, which accounts for >10% of the world’s barrier islands. Little more than large, partially vegetated, subaerial sand bars, barrier island provide for recreation, ecosystem services, and protection of mainland communities from storm impacts. They are also some of the most dynamic features on earth, constantly changing in the face of waves, tides, wind, and currents. With examples from northern Massachusetts and the Virginia Eastern Shore, this talk will focus on the long-term sustainability of barrier islands, and …
