In late
April, an international team of researchers working under the auspices of the
Integrated Ocean Drilling Program (IODP) launched the New Jersey Shallow Shelf
Expedition in the early hours one morning, taking advantage of the high tide to
sail to the continental shelf just off the New Jersey shore. There, they will
conduct coring operations to collect geological sediments that will inform them
about Earth cycles that relate to sea level change, the mechanisms that force
it, and that have impacted the geography of the shoreline over time.
“Researchers
have drilled on the coastal plain and the continental slope to learn about sea
level change from its highest to lowest levels over the last 35 million years,”
says co-chief scientist Gregory Mountain of Rutgers University, Dept. of Earth
and Planetary Sciences. “Access to the records in our current drill target will
provide us with missing information that bridges those two sets of records. The
new samples will enable us to determine time, rate and magnitude of changes
that have occurred over the last 35 million years and lead us to improve our
understanding of coastal response to sea level rise, one aspect of climate
change.”
The
expedition is funded primarily by a consortium of 17 European countries called
the European Consortium for Ocean Research Drilling (ECORD), in partnership
with the U.S. National Science Foundation, Japan Ministry of Education,
Culture, Sports, Science and Technology, The People’s Republic of China, The
Republic of Korea, Australia, India, and New Zealand. Additional support for
this expedition was provided by the International Continental Scientific
Drilling Program.
“This is
the first expedition that afforded an opportunity for IODP and ICDP to co-fund
a drilling project that results in sediment records that both research groups
are eager to acquire,” explains ECORD managing agency director Catherine Mével.
“This expedition completes the transect from land to sea initiated 15 years
ago.”
The
Integrated Ocean Drilling Program is an international marine research program
dedicated to advancing scientific understanding of the Earth through drilling,
coring and monitoring the sub-seafloor.
