Long-term changes in the Earth's climate caused global sea level to
rise or fall, as polar ice melted or froze.
These changes in sea level are recorded in the sedimentary structures
at continental margins.
Much of our knowledge on the history of the Earth's climate comes from
studying seismic reflection profiles of
these structures.
Interpretation of climate signals in margin sediments is complicated by
local tectonic forces that cause
parts of the margins to rise or subside, independent of climactic
changes.
This research cruise is designed to help develop the tools and
understanding that will enable researchers
to separate the climatic and tectonic effects seen in margin sediments.
