Shell Oil has funded a proposal by Cquestrate to investigate atmospheric carbon removal by adding lime to sea water. This process is heavily energy intensive, but could still be cost-effective near oil fields that have un-utilized natural gas resources. Instead of flaring the gas, it could be harnessed to create lime from limestone. Notably, the company developing this proccess plans to use an “Open Source” development process so that anyone can use the technology.
Read a Wired article on the process.
Read about the open source methodology, and visit the company’s website.

A new paper in the Proceedings of the National Academies shows that nutrient-rich discharge greatly enhances the biological pump mechanism of carbon sequestration. The sequestration happens as the discharge plume enters deep water off the continental shelf, where excess iron, phosphorous, and silica stimulate diatoms and nitrogen-fixing diazotrophs. The measured carbon sequestration rates are very high in the area of the discharge plume.

The Christian Science Monitor published this article, “Can we engineer a cooler Earth?“, which discusses the need for geoengineering as a stop-gap approach until the world can implement meaningful CO2 emissions cuts. Also mentioned is the need to begin researching how geoengineering could be conducted responsibly.

Katie Fehrenbacher at Earth2Tech covers the relaunch of Planktos under “Planktos-Science.com”.
She notes: “If Planktos Science wants to be a serious company, they should get some serious PR help.”

The July 3rd edition of Time Magazine has a story on OIF and other technologies to actively remove CO2 from the atmosphere. The story goes into significant detail on the reasons why CO2 sequestration is important, and on how OIF would accomplish this. Climos is covered, including a quote by Dr. Margaret Leinen.

Popular Science provides a nice post-mortem on Planktos, which ceased operations last February. The story of Planktos is a good example of the need for effective regulation of OIF activities under the London Convention.
The last page of the article has some nice coverage of Climos and the way forward with OIF. There are quotes by Dr. Ken Buesseler of the Woods Hole Oceanographic Institute, and by Dan Whaley and Margaret Leinen of Climos.
