BOEM and Atlantic Sand Assessment Project

The Bureau of Ocean Energy Management (BOEM) and the Lamont-Doherty Earth Observatory (LDEO) will dedicate the Atlantic Sand Assessment Project (ASAP) core storage repository on Tuesday, October 25 at 11:00 a.m. The collection is a result of the BOEM-funded project to create a new inventory of potential offshore sediment resources in Federal waters in the Atlantic. The project involved collecting, analyzing and cataloging sediment cores from federal waters offshore 11 East Coast states from Miami, 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.

Huge Iceberg Broken off Antarctica Heads for Open Ocean

Scientists are monitoring an iceberg roughly six times the size of Manhattan - one of the largest now in existence - that broke off from an Antarctic glacier and is heading into the open ocean. NASA glaciologist Kelly Brunt said on Wednesday the iceberg covers about 255 square miles (660 square km) and is up to a third of a mile (500 meters) thick. Known as B31, the iceberg separated from Antarctica's Pine Island Glacier last November, Brunt added. "It's one that's large enough that it warrants monitoring," Brunt said in a telephone interview, noting that U.S.

Before the close of the inaugural Oceanology International China (OI China) held in Shanghai in early September, more than 70% of the space available for the next show in the series, being held September 3-5 , 2014 at INTEX Shanghai, had been reserved. “Our new show in the long-standing Oceanology International series not only lived up to expectations, but exceeded them,” said Event Director James Coleman of Reed Exhibitions. “4,296 visitors attended over the three days, making 5…

Muddy Footprints: Satellite's View of Ship Pollution

Global NOx Map: Image credit NASA

Long tracks of elevated nitrogen dioxide (NO2) levels show up along certain shipping routes when viewed from NASA's Aura satellite. For more than a decade, scientists have observed “ship tracks” in natural-color satellite imagery of the ocean. These bright, linear trails amidst the cloud layers are created by particles and gases from ships. They are a visible manifestation of pollution from ship exhaust, and scientists can now see that ships have a more subtle, almost invisible, signature as well, according to 'NASA Earth Observatory'.

$1.3 Million Grant for Deepwater Horizon Research

University of Georgia marine scientist Samantha Joye, who is the Athletic Association Professor in Arts and Sciences, and UGA colleagues Patricia Medeiros and Christof Meile have received a $1.3 million grant from the Gulf of Mexico Research Initiative that will enable UGA researchers and scientists from 13 other institutions to understand more thoroughly the ecosystem impacts of the 2010 Deepwater Horizon oil spill. The three-year grant, awarded through a competitive merit-review process by a board comprised of researchers from academic institutions, will allow scientists and emergency responders to better predict and respond to future spills, should they occur.

First Non-Military Standard, Underwater Noise

A new voluntary consensus standard for the measurement of underwater noise from ships is now available from the Acoustical Society of America (ASA) and the American National Standards Institute (ANSI). The new standard will be known as ANSI/ASA S12.64-2009/Part 1, “American National Standard, Quantities and Procedures for Description and Measurement of Underwater Sound from Ships- Part 1: General Requirements”. Noise Control Engineering, Inc. of Billerica, Mass. led the effort to develop the new standard having its Vice President Michael Bahtiarian chair the committee. NCE also provided significant administrative resources to completing the effort. “We started this effort to fill a need for NCE clients designing and building quiet research vessels,” noted Chair Bahtiarian.

Clearwater Collects Data for Stevens' Maritime Lab

Later during the week of June 22, researchers at Stevens Institute of Technology will equip the sloop Clearwater with instrumentation that will provide real-time transmission of position, time, surface water temperature, salinity, and dissolved oxygen concentrations in the northern area of the Hudson River. The installation is the latest component in the Hudson River Environmental Conditions Observing System (HRECOS), which is operated by a consortium of partners in government and the research community. HRECOS provides data in real-time to allow for the immediate assessment of ocean, weather, and environmental conditions throughout the waters of the Hudson River. Earlier this year, Dr. Alan F.

NASA Image: Ship Tracks

On March 4, 2009, the skies over the northeast Pacific Ocean were streaked with clouds that form around the particles in ship exhaust. This pair of images shows how these ship tracks are different from the natural marine clouds in the same area.

Answering the Call From Above

Selecting a "Technology-of-the-Year" for the June 2002 Yearbook edition of Maritime Reporter & Engineering News was no small task, and a decidedly unscientific one, at that. There were no editorial boards, voting slips, gala dinners or plaques. Simply put, the editors of MR/EN arrived on Satellite Communications technology as the centerpiece of its largest edition based on observation, discussion and analysis of the companies that have develop, supply, test and purchase the products and services that fall under its broad category.Words alone cannot summarize the technological revolution that has swept the world during the past decades. Consider for a moment a world without the Internet, e-mail or seamless, high-capacity communication links.

CMC Celebrates Earth Station's 25th Anniversary

COMSAT Mobile Communications' (CMC) Santa Paula, California, earth station is celebrating 25 years of continuous, around-the-clock operations, providing the critical communications link for customers on land, at sea, and in the air. CMC's west coast facility provides Inmarsat satellite communications coverage from western North America, across the Pacific Ocean and into Asia, the Pacific Rim nations, New Zealand, Australia, and the eastern Indian Ocean. The Santa Paula station has served as a principal communications lifeline providing instant communications to ships at sea, aircraft, and to people located in parts of the world where there is no communications infrastructure. For a quarter century, Santa Paula has often provided their sole means of contact with the rest of the world.
