11:30 am - 1 pm NESTA Earth and Space Science Educator Luncheon

Join other Earth and space science educators for a sit-down lunch including a lecture by Prof. Steven Hovan (Indiana University of Pennsylvania), who will speak about "Dust in the Wind – The Geological Record of Ancient Atmospheric Circulation".

Abstract - The atmospheric wind pattern is closely tied to global climate changes of
the Earth's past. As global climates warm and cool, winds respond by
changing strength and zonal patterns migrate accordingly. But how exactly
do we capture the geological record of ancient winds? Hovan's research
involves tracking the strength and location of ancient atmospheric
circulation using dust carried to the oceans by the winds. Dust blows
from the continents and is carried to the oceans where it eventually
settles as part of the the debris we call seafloor sediments. Once
isolated, different characteristics of the dust material can be used to
track ancient winds and their response to sudden or long-term climate
