Guest Scientist: Alexey Kaplan—“Developing Knowledge of Climate during the Past 150 Years”In the first part of today’s program, Dr.
Kaplan explores how we have learned about climate and climate
change through a historical survey that begins with ship
observations of ocean surface, analyses of sea surface
temperatures, sea level pressure and surface winds from 1850s
to the present observation of global scale climate variability
possible through satellites. Guest Scientist Rusty Lotti Bond—“The LDEO Deep-Sea Core Repository”Next, we visit Rusty Lotti Bond, Curator of the Lamont-Doherty Deep-Sea Sample Repository, the largest collection of material from the below the ocean floor. You can learn more about this collection at http://www.ldeo.columbia.edu/CORE_REPOSITORY/RHP1.html For more than fifty years, the Repository collection of sediment samples has provided material for scientists worldwide to research many facets of our earth's systems. Deep-sea cores contain microfossils and minerals that can be used as environmental indicators, or reveal climate change. Variations of color and texture resulting from changes over time in the sediment are clearly visible in the cores. The dynamics and significance of these changes will be explored in the workshop.
