Abstract
This seminar will use a 17-year time series of hydrographic data collected
from the continental shelf of the western Antarctic Peninsula. These data
were obtained from cruises undertaken as part of the Palmer Long-Term
Ecological Research program. The data set was analyzed to obtain estimates
of heat storage and heat flux for the western Antarctic Peninsula. This
analysis is used to examine the role of changes in ocean heat over the
17-year period in an attempt to explain the wintertime atmospheric warming
that is occurring in this region, which is the largest atmospheric warming
on Earth. The ocean is an obvious source of winter heat that could be
driving this warming.
Biography
Dr. Martinson received a Ph.D. degree from Columbia University. He is
currently a Senior Research Scientist in the Division of Ocean and Climate
Physics at the Lamont-Doherty Earth Observatory. His research focuses on
the role of the polar oceans, particularly ocean-ice interactions, in global
climate. He also does research related to paleoclimate studies and the
development of quantitative data analysis tools.
