On the NH seacost, the ocean plays an important role in our daily lives. Researchers at UNH explore all aspects of the interplay of humans with the sea. At this event we will hear how the ocean chemistry affects the ocean’s ability to absorb carbon dioxide from the atmosphere, how our dynamic coastlines evolve over time and how coastal floods impact the design of our roadway infrastructure.
Earth’s Climate Control: The Role of the Oceans in the Global Carbon Cycle
Prof. Robert Letscher (Assistant Professor of Chemical Oceanography, Department of Earth Sciences &, Ocean Process Analysis Laboratory, UNH)
Earth’s oceans cover 71% of its surface and contain 99% of its habitable volume, making Earth truly the Water Planet. Ocean biology and chemistry play a very important role in regulating Earth’s climate through their influence of atmospheric CO2 levels. Dr. Letscher will discuss his research into the cycling of biological nutrients and carbon in the sea and its link to past, present, and future climate trends.
When “Dry” Infrastructure Gets Wet: Climate Resilience for Precipitation and Flooding
Prof. Kyle Kwitakowski (Assistant Professor, Civil and Environmental Engineering, UNH)
Precipitation and flooding can negatively impact roadways and bridges, causing damage, economic disruption, and loss of life. This is already a problem in many areas of the world, from New Hampshire to sub-Saharan Africa, and is predicted to get worse in the future. Kyle will show examples precipitation and flooding impacts around the world and discuss what we can do to protect our infrastructure and the communities it supports.
From sand grains to coastlines
Prof. Diane Foster (Professor, UNH)
The coastal environment exhibits complex feedback between waves, currents, and beaches. This is visible at scales ranging from sand grains to entire coastlines. Diane will discuss her research on evolving coastlines and the tools ocean engineers use to help predict large-scale beach evolution.
