Final call for 2015 Award Nominations
The Oct. 31 deadline for 2015 Award Nominations is closing in. Thank you to those who have already submitted nominations or are in the final preparations, your nominations are invaluable to the process. If you haven't participated yet, please take the time to consider the accomplishments of your valued colleagues by nominating them. With your help, we can ensure the award committees have a diverse and deserving pool of candidates to consider. Your participation in the awards program by being a nominator or by writing a supporting letter of recommendation not only benefits the nominee, it also benefits the geochemical community.
Analab manufacture corrosion resistant laboratory appliances such as acid vapour cleaning stations, hotplates, and sample preparation devices. Our devices can be used with a wide range of acids and bases (HF to NH4OH). We are represented in North America by Isomass Scientific.
Please visit us at GSA 2014 in Vancouver, Booth 1018.

Earth's magnetic field could flip within a lifetime
University of California, Berkeley
Imagine the world waking up one morning to discover that all compasses pointed south instead of north.
It's not as bizarre as it sounds. Earth's magnetic field has flipped — though not overnight — many times throughout the planet's history. Its dipole magnetic field, like that of a bar magnet, remains about the same intensity for thousands to millions of years, but for incompletely known reasons it occasionally weakens and, presumably over a few thousand years, reverses direction.
Mature forests store nitrogen in soil: May help protect waterways from excess nitrogen from industry
Ecological Society of America via ScienceDaily
Ecologists working in central Pennsylvania forests have found that forest top soils capture and stabilize the powerful fertilizer nitrogen quickly, within days, but release it slowly, over years to decades. The discrepancy in rates means that nitrogen can build up in soils. Forests may be providing an unappreciated service by storing excess nitrogen emitted by modern agriculture, industry, and transport before it can cause problems for our waterways.
Pre-AGU 2014 CIDER Workshop
This one-day workshop serves as a kick-off for the CIDER 2015 summer program and as a retrospective on the CIDER 2014 summer program. It will be held Dec. 14, just before AGU in Berkeley, California. The workshop is open to all, and we particularly encourage those that have not experienced CIDER but would like to find out more about it. The registration deadline is Nov. 12.
