Study Examines Iceberg Shifts In North Atlantic

Some Heinrich events – periodic massive iceberg surges into the North Atlantic that were previously thought to have weakened the global ocean conveyor belt circulation and sent Earth’s climate into the deep freeze – may actually have been caused by changes in atmospheric circulation patterns, say a team of researchers that includes two Texas A&M University professors.

Large Dead Zone Growing in Gulf of Mexico

Ocean experts had predicted a large “dead zone” area in the Gulf of Mexico this year, and according to the results from a Texas A&M University researcher just back from studying the region, those predictions appear to be right on target (read more).

Oceanographers make global splash

It's been a productive season for oceanographers Matthew Schmidt, Ping Chang, Mitch Lyle and Steve DiMarco. Chang is lead author on a recent PNAS article, and Schmidt is lead author on a second one with Chang also contributing. Lyle is a contributing author in a Nature article. And DiMarco has received more than 25 million unique views in media around the world for his recent hypoxia research in the Gulf of Mexico.

 
Three hundred ninety-seven miles of beaches; an abundant source of vacation activities; ample fishing, waterfowl hunting, and birding; major ports that are the economic engine of the community; commercial fisheries—this is the Texas Gulf Coast, an abundance of natural resources with an economic interplay critical to the state of Texas (read more).
 

Science pioneers are blazing a trail to identify pathways oil and gas use to move from deep to surface waters – an entry point for pollutants to damage shorelines and become airborne. Near the Deepwater Horizon spill site, researchers are investigating mixing patterns in the deep ocean by following the path of an inert tracer, trifluoromethyl sulfur pentafluoride, injected at about 1,100 meters depth and recording ocean conditions along the way (read more).

 

AAAS names Thomas Bianchi a Fellow

Prestigious scientific organization will induct Bianchi in February

Washington D.C.—Thomas Bianchi, Department of Oceanography, has been named a Fellow of the American Association for the Advancement of Science (AAAS).

As part of the Section on Atmospheric and Hydrospheric Science, Bianchi was selected as an AAAS Fellow for fundamental contributions to understanding the organic carbon cycling in coastal marine environments and for help in defining the field through his synthesis efforts (read more).

 
The melting rate of certain glaciers in Antarctica is unmistakably accelerating and the most direct link to global warming is in the unknown adjustment of the surrounding Southern Ocean. That leads to not only an uncertain future stability of the icy continent but also raises questions about the pace of sea level rise around the world, according to work by a Texas A&M University researcher (read more).
 

Texas A&M oceanographer guest edits scholarly magazine

As with any profession, scientists yearn for the moment they can look at their work and realized they’ve made it. For one Texas A&M oceanographer, the chance to be a guest editor for the prestigious Oceanography magazine represents the culmination of a career well spent – after years of research in the Southern Ocean aboard the RVIB Nathanial B. Palmer, Dr. Alejandro Orsi was privileged to tell the world about the vessel that made his research possible. (read more)

 

Bombs in Gulf of Mexico Pose Big Problems

Millions of pounds of unexploded bombs and other military ordnance that were dumped decades ago in the Gulf of Mexico, as well as off the coasts of both the Atlantic and Pacific oceans, could now pose serious threats to shipping lanes and the 4,000 oil and gas rigs in the Gulf, warns two Texas A&M University oceanographers.
