The Dialogue on Science, Ethics, and Religion (DoSER) Program at the American Association for the Advancement of Science invites you to join us:

as we explore new findings in the search for planets and life beyond Earth. No longer science fiction, new extrasolar planets are being discovered at an incredible rate, some potentially habitable. Astrobiologist Stephen Freeland will describe how the burgeoning field of astrobiology is revealing the robust and tenacious nature of life even in extreme conditions on Earth and whether we can expect life elsewhere to be common. Historian Steven Dick will respond with insights on the implications of these new findings for our understanding of the significance of life in the universe.

June 19, 2013

Lecture and Discussion, 2nd floor auditorium
5:30 to 7:00 PM
Reception to follow.

OUTREACH ASSOCIATE

AMERICAN GEOSCIENCES INSTITUTE

The American Geosciences Institute (AGI) invites applications for its Outreach Associate, a paid, full-time position starting immediately. The Outreach Associate reports directly to the AGI Outreach Manager and undertakes a variety of duties for the AGI Outreach and Education departments, including writing and editing, preparing electronic documents and updating Web pages, and various clerical functions. A major responsibility is project support for Earth Science Week, an annual public awareness campaign promoting education in the geosciences. A bachelor’s degree in earth science or earth science education and computer skills (Microsoft Office, HTML, Dreamweaver, Photoshop) are required. Qualified candidates must submit a cover letter, resume, and contact information for three references to Geoff Camphire, Outreach Manager, American Geosciences Institute, 4220 King Street, Alexandria, VA 22302, gac@agiweb.org. Applicants are encouraged to learn more about AGI (http://www.agiweb.org) and Earth Science Week (http://www.earthsciweek.org).

AGI is a nonprofit federation of geoscientific and professional associations that represents more than 250,000 geologists, geophysicists and other earth scientists. Founded in 1948, AGI provides information services to geoscientists, serves as a voice of shared interests in the profession, plays a major role in strengthening geoscience education, and strives to increase public awareness of the vital role the geosciences play in society’s use of resources, resiliency to natural hazards, and interaction with the environment. AGI is an equal opportunity employer.

MiniSipper: A New Concept for High-capacity, Long-duration, Automated In Situ Water Sampling

MiniSipper: A New Concept for High-capacity, Long-duration,

Automated In Situ Water Sampling

Thomas Chapin

(Former Mendenhall Fellow)

Crustal Geophysics and Geochemistry Science Center, Denver, CO

Most environmental water quality monitoring studies rely on hand-collected “grab” samples for water sample collection. However, grab sampling is expensive with significant costs for personnel, equipment, vehicles and travel. Field costs can be especially high if the sampling site is remote, dangerous to access, or snowbound for many months of the year. Grab sampling typically provides a few samples per year and this low temporal resolution sampling rarely captures the details of major transient hydrologic processes such as storm, flood, or seasonal runoff events. Currently available automated samplers could provide water sampling at remote sites, but these samplers are typically large, heavy, collect 24 one liter samples, and are not well suited for operation in freezing conditions.

The USGS has developed a small, light, low-cost, high-capacity, in situ water sampler, the MiniSipper, to overcome the limitations of current automated water samplers. The MiniSipper injects 2 to 10 mL discrete or integrated water samples into a 500’ Telfon sample coil. Nitric acid is added to stabilize each sample and individual water samples are then separated with a gas bubble. Over 250 five mL water samples can be collected with <5% carryover. The MiniSipper collects samples in situ for up to 12 months unattended and even operates under ice for over-winter sampling. After recovery, samples are pumped out of the sample coil and analyzed by high sensitivity multi-element methods such as ICP-MS.

The MiniSipper provides long-duration high-resolution metal data for hydrologic and geochemical processes that are almost impossible to observe with currently available sampling methods. MiniSipper technology is very flexible and MiniSippers has been used for acid mine drainage studies (above and below ground), tracer studies (above and below ground) and for post-wildfire runoff studies. The Borehole MiniSipper is designed for well monitoring, fits down a 2” borehole, and collects weekly samples over an entire year. The MiniSipper has primarily been used for metal analysis but this technology should be applicable to other analytes of interest such as organics, pesticides, nutrients, etc. This presentation will: 1) give an overview of the MiniSipper instrumentation; 2) present results from high-resolution acid mine drainage and post-wildfire monitoring; and 3) discuss applications currently under development such as the Event Response MiniSipper and the Disaster Response MiniSipper. Bring your sampling needs, ideas and problems; perhaps the MiniSipper could offer a solution.

Here are the course descriptions for the first three courses being offered on the Loudoun Campus:

Grain Size Analysis:  This course introduces students to sediment analysis.  It provides hands-on practical experience on how to process and analyze sediment samples in order to determine depositional environment.  Students will learn how to sample, wet sieve, dry sieve, pipette and interpret the data.

Four Week

PREREQUISITE:  GOL-105 or an equivalent course is recommended.

Micropaleontology Techniques:  Provides hands-on techniques for extracting microfossils from a variety of rock types.  Focuses on basic knowledge of microfossil types and their environment of deposition, the correct method needed to obtain sample specimens, and basic data graphing techniques.  Prerequisites: It is recommended that the student has completed GOL 106 or an equivalent historical geology course.

Four Week

Prerequisites: It is recommended that students have completed GOL 106 or an equivalent historical geology course

Core Description:  This course instructs students in the fundamental techniques involved in rock core and sediment collection and description. The student will learn the basic collection methods for subsurface rock and sediment samples, how to identify pertinent features of the samples for various types of geological investigations, and protocols for storage and management of the samples.

Two Week

It is strongly recommended that students have  completed GOL105 or an equivalent physical geology course before enrolling in this class.

Check Loudoun and Annandale Summer course schedules
Each course is worth 1 credit
All require GOL 105 (or equivalent) as prerequisite
Hard Rock Techniques requires GOL 207 (or equivalent) as prerequisite

Prof. Bentley’s talk is entitled “Snowball Earth”.  During a massive planetary ice age that occurred 700 million years ago, ice stretched from Earth’s poles to the equator and the resulting climate change switched the planet from domination by microbial slime to an oxygenated place with the very first animal fossils. Three sites in Virginia record this extraordinary tropical-latitude glaciation, which was only ended when volcanic activity induced global warming. As Prof. Bentley will explain, it’s a big story, a true scientific controversy, and a compelling brain-stretcher of a tale that will make us think about connections between climate, plate tectonics, weathering of rock, animal evolution, and ocean circulation.

Please join us on Saturday, Mayy 25th, at the Fort Valley Library and Community Center, 6190 Woodstock Tower Road, Fort Valley, VA 22652 (540-933-6714).
