Elemental Traces in the Atlantic: The final chapter

Jeremy Jacquot's blog for EARTH, "Elemental Traces in the Atlantic," detailed the scientific journey of the first U.S. GEOTRACES expedition. Read his other blogs here and here, and the original story on GEOTRACES as it appeared in EARTH here. Stay tuned for a wrap-up of the cruise in EARTH early next year.

Elemental Traces in the Atlantic: The art of clean sampling

Follow my blog at EARTH online, "Elemental Traces in the Atlantic," over the next couple of months, where I’ll be writing from the ship and detailing the scientific journey. And stay tuned early next year, when EARTH and I will bring you a wrap-up of the cruise. Read the original story here.

Think of the cleanest, most meticulous person you know and multiply that attention to detail by about an order of magnitude. That’s what it takes to be considered trace-metal “clean.”

Cruising the Atlantic to trace elemental movements

When it comes to the science of climate change, one of the least understood issues is the oceans’ future in a changing global environment. Measurements over the past two decades show that the oceans’ surface waters have been warming since the 1950s, and that large influxes of carbon dioxide have already made the oceans more acidic.

Blogging on EARTH: Climate change threatens Virginia's vacation spots

Each year, millions of visitors flock to Virginia’s natural wonders, such as Shenandoah National Park, and to historical landmarks, like Jamestown, one of America’s earliest colonies. But a new report by the National Resources Defense Council (NRDC) states that many of Virginia’s landmarks are jeopardized by climate change.

Water Wise: An oil plume at depth, and NOAA vs. the White House

There is definitely a deep plume of oil in the Gulf of Mexico, and it was definitely produced by BP’s damaged Macondo well, according to a report published today in Science. Scientists from the Woods Hole Oceanographic Institution (WHOI) in Massachusetts reported unequivocal evidence of a plume at a depth of about 1,100 meters that was at least 35 kilometers long, as of the end of June. The plume, they said, was traveling to the southwest, largely driven by the topography of the seafloor.

Comment: Volcanic versus anthropogenic carbon dioxide: The missing science

“Volcanoes add far more carbon dioxide to the oceans and atmosphere than humans.” So says geologist Ian Plimer of the University of Adelaide in his 2009 best seller “Heaven and Earth: Global Warming — the Missing Science.” With this assertion, Plimer brings volcanic carbon dioxide degassing front and center in the climate change debate, reviving and reinforcing this wildly mistaken notion.

Hazardous Living: Climategate climatologists cleared of wrongdoing

Last November, a thousand private e-mails between prominent climatologists were hacked, resulting in a brouhaha that threatened to discredit the work presented in the Nobel Prize-winning Intergovernmental Panel on Climate Change’s Fourth Assessment Report.
