First Nippon Foundation-GEBCO Seabed 2030 Project Meeting

The first Nippon Foundation-GEBCO Seabed 2030 Project regional mapping meeting for the Atlantic and Indian Oceans took place this month at the Lamont-Doherty Earth Observatory of Columbia University. The meeting in Palisades, NY, was chaired by Dr Vicki Ferrini, who leads the Seabed 2030 Atlantic and Indian Ocean Regional Data Center.  In order to better raise awareness of complementary mapping efforts in the region, the session was coordinated to coincide with a US Federal Agency Working Group on Coastal and Ocean Mapping, as well as a meeting of the leads of the Atlantic Ocean Research

Case Study: Mapping a Glacial Landslide

; In October of 2015, a massive landslide was detected at Tyndall glacier in southeast Alaska, sending an estimated 145 million tons of valley wall into Taan Fiord. The landslide’s significant mass created a seismic signature that was detected by seismologists thousands of miles away at Columbia University in New York. Taan Fiord is an arm of Icy Bay in southeast Alaska. Over thousands of years, Tyndall Glacier eroded the valley walls creating very steep sidewalls. Over the past several decades, Tyndall Glacier has retreated, no longer supporting those sidewalls. The steepening and then debuttressing

, Florida, to Massachusetts beginning in 2015. The core analysis provides important information on thickness of sediment layers, composition of sediment layers, organic material content, and overall compatibility with beach sands.  LDEO is a world-renown earth sciences institution located at Columbia University’s campus in Palisades, N.Y. The Lamont-Doherty Core Repository, established nearly 70 years ago, contains one of the world’s most important and unique collections of scientific samples from the deep sea. The dedication and tour will include remarks by Renee Orr, Chief of BOEM&rsquo

How Do Desert Storms Affect Ocean Phytoplankton?

winds sweep these particles as far as the Pacific, where dust ultimately settles in the open ocean. This desert dust contains, among other minerals, iron — an essential nutrient for hundreds of species of phytoplankton that make up the ocean’s food base.   Now scientists at MIT, Columbia University and Florida State University have determined that once iron is deposited in the ocean, it has a very short residence time, spending only six months in surface waters before sinking into the deep ocean. This high turnover of iron signals that large seasonal changes in desert dust may have dramatic

The high diversity of phytoplankton has puzzled biological oceanographers for a long time. There are over 200,000 species of of these tiny marine plants that use sunlight and nutrients to grow and reproduce at the ocean's surface. (Courtesy of Samantha DeCuollo,University of Rhode Island)

Coexisting in a Sea of Competition

, and all of those species of microscopic marine plants that form the base of the marine food web need the same basic resources to grow—light and nutrients.   A study by a team of scientists from the Woods Hole Oceanographic Institution (WHOI), University of Rhode Island (URI), and Columbia University, published April 13 in the Proceedings of the National Academy of Sciences reveals how species of diatoms—one of the several major types of marine phytoplankton—use resources in different ways to coexist in the same community.   "The diversity of phytoplankton has puzzled
