Lamont-Doherty Open House 2018 was a great success and so much fun! The Core Repository was teeming with people all day. We had a great diversity of researchers at different stations in the repository, showing off their research and hosting hands-on activities for students of all ages to participate in. We can't wait for Lamont-Doherty Open House 2019 on Saturday, October 5th. Mark your calendars and check the Open House website for updates!

The incoming first year graduate students have arrived on campus! Today they toured around campus and they are headed out on a camping trip in Vermont for the next couple of days before they start classes on Tuesday. Welcome to all and welcome back to campus for some, including our own Clara Chang (front row, left) who has been working in the Core Repository for the last three years. We're excited to have you all on campus and thanks for stopping by the Core Repository!

A BOEM-funded Hurricane Sandy initiative is creating a new inventory of potential offshore sediment resources in federal waters in the Atlantic.

The project involved collecting, analyzing and cataloging 189 sediment cores offshore 11 East Coast states from Miami, Florida, to Massachusetts beginning in 2015. These cores are now part of the Lamont-Doherty Core Repository's collection.

Coastal managers, scientists and others will be able to access the physical core samples and the new data, which will be shared through Lamont’s System for Earth Sample Registration (SESAR) at Ultimately, the full set of ASAP metadata will be accessible through Lamont’s main database, the Index to Marine and Lacustrine Geological Samples (IMGLS), Data sets available include core descriptions and photographs as well as grain size analysis.

BOEM has recently published summary reports on efforts by state agencies and state universities to update maps and consolidate databases related to offshore sediment resources. These activities were made possible through cooperative agreements between BOEM and 13 Atlantic states from Florida to Maine in 2014. Summaries of the cooperative agreement reports are available at the Marine Minerals Program’s revamped website:

The mission of BOEM’s Marine Minerals Program is to facilitate access to and manage the Nation’s (OCS) non-energy marine  minerals, particularly sand and gravel, through environmentally responsible stewardship of resources, prudent assessments of exploration and leasing activities, coordination with governmental partners, engagement of stakeholders, strategic planning, and mission-focused scientific research to improve decision-making and risk management.

We have a lot of projects going on at the Core Repository this summer, as well as a few new faces.  Alex and Deandra will be working on our Carbonate Project this summer, creating high resolution carbonate transects of the Atlantic and Pacific Oceans from our core collection.  Deandra is a recent graduate of Ithaca College, and Alex just finished his first year at Carleton College. 

Frank just finished his first year at Cornell University. He is working on our educational outreach materials! Here he is photographing microfossils retrieved from our collection. 

Ellen, Kateri, and Ian are local high school students who will be organizing our coral collection this summer.

The Core Repository is proud to show off its brand new Visualization Hyperwall system for use with Corewall core description and data visualization software, scientific data processing, and educational scientific visualizations! And best of all, it is accessible by anyone using the corelab facilities!

The Hyperwall is a 3 x 2 array of six 30" Ultrasharp (2560x1600) Dell Monitors powered by a MacPro configured with 12 Intel Xeon cores at 3.06Ghz, 64GB of RAM, and dual high-performance ATI Radeon HD 5770 1GB graphic cards.

The Hyperwall running Corewall - sediment core images are superimposed with data such as density, natural gamma, and magnetic susceptibility.

Open House is nearly upon us (October 6)! Come and find out the how’s and why’s of sediment cores: how we get them from the bottom of the oceans and why they are invaluable to climate research. They’re more than just mud!
The Core Repository is happy to welcome Angel Mojarro as our new lab technician, core sampler and all around right-hand man! Angel graduated from Brown University '11 with a Bachelor of Science in Geology where he studied the evolution of the El Nino Southern Oscillation since the Last Glacial Maximum. In his first few weeks, Angel has had a steep learning curve and proven that he is more than up to the challenge. Welcome Angel!

Climate scientist Braddock Linsley is back from American Samoa, where he and Stanford colleagues Robert Dunbar and David Mucciarone, collected possibly the oldest continuous Porites coral records. The three coral samples they recovered go back an estimated 550 years; the group collected the corals while scuba diving on a massive, exposed Porites reef off the island of Ta'u. Cores from this colony may help scientists track climate change in the Western Pacific Warm Pool and South Pacific Convergence Zone as far back as the early 1400s, at the start of the Little Ice Age. The corals may also provide context for current changes in climate and ocean currents, allowing scientists to test the hypothesis that rain belts along the equator are becoming more active.

Ocean Floor Reveals Past Climate Changes 
Voice of America, January 9, 2012
Maureen Raymo, director of Lamont-Doherty's Core Repository, speaks about the significance of sea floor sediments in studying the environmental impacts of climate change.
Nichole Anest has been promoted to curator of Lamont's extensive library of seafloor sediments, replacing Rusty Lotti who retired last year. With a geology degree from Rutgers, Anest came to the Core Repository in 1998 and wrote descriptions of the sediment cores and isolated plankton fossils that could be used to measure past fluctuations in the earth's climate. She was soon running the X-ray machine and other tools to analyze the cores. Over the next decade, she would process, analyze and catalog new cores while keeping all the lab machines running. The Core Repository is now undergoing a major renovation under its first director, paleoclimataologist Maureen Raymo. "The fact that every core potentially holds new insights into the Earth's past still amazes me," said Anest. "The past year has been overwhelming at times with the moving of most of our collection, but when the dust settles, we will have a fabulous new space to study cores as well as state of the art facilities to analyze their secrets."

Big changes are underway at the Lamont-Doherty Core Repository. This past summer was spent moving our entire dry core collection from the first floor space in the Core Laboratory building (where they have been for almost 50 years) to the old ODP East Coast Repository space in the basement of the Geoscience Building. The bright new space reunites the dry cores with the wet core collection currently housed in “Reefer 4”. Within a few months, the core sampling operation will also relocate to this new location and currently a major renovation of the laboratory space, funded by LDEO, is underway. Future sampling of all of Lamont’s cores (both wet and dry) will take place in this new and beautiful space.
Meanwhile, the renovation of the second floor of the New Core Lab building is in full swing -- it is getting a $9 million facelift funded by NSF. This will transform the second floor into the new Lamont Center for Biogeochemistry. This renovation will provide a dozen new, state-of-the-art labs for both organic and inorganic geochemistry and be home to most of the analytical space for our division. Under a separate NSF award, four new mass spectrometers were purchased this year for measuring stable isotope ratios on carbonates, water, and organic compounds, and Prof. Brad Linsley is the new director of this analytical facility. With all this activity we’ve been on a hiring spree over the last couple of years, and many new faces can be found around the Core Laboratory and Geoscience Buildings.
In August, Rusty Lotti, who served as the repository curator for 26 years, retired after 37 years of fabulous service to Lamont. Her dedication to the preservation of the core collection helped make our facility one of the best in the world for archiving and analyzing deep-sea sediments. Repository employee Nichole Anest is serving as Interim Curator and is working closely with the new repository Director, Prof. Maureen Raymo, in planning for the future.
Finally, if you are reading this you have visited our new web site. We are working to continually add content and improve our user and data interfaces. Please feel free to send suggestions to the Curator.
