“Hypoxic zones are areas in the ocean of such low oxygen concentration that animal life suffocates and dies, and as a result are sometimes called “dead zones.” One of the largest dead zones forms in the Gulf of Mexico every spring. This data visualization discusses the causes of hypoxia in the Gulf of Mexico.”

“Applications are invited for the position of post-doctoral researcher to study soil carbon cycling at broad spatial scales and coordinate activities of the National Soil Carbon Network (NSCN). This position is jointly funded by the USDA Forest Service, US Geological Survey, and Northern Institute of Applied Carbon Science. General responsibilities will include:

  1. “Database development: Support the development of a coherent, searchable, and expandable database with an advanced analysis environment. This database will be oriented to a wide range of individual investigators, small networks, and national agencies interested in spatially explicit soil C information.
  2. “Data synthesis: Test the efficacy of the database and interface by combining data from multiple large datasets and individual users, comparing multiple data input forms (isotopes, spectral analysis, etc), and producing a distinct synthesis product related to soil C distribution and vulnerability.
  3. “Community organization: Support NSCN workshops focused on data-sharing, protocol-development, and advanced website engineering for database interaction and community discussion; disseminate Network products and draw increased participation and collaboration through the web and NACP activities.

“A PhD in soil science, biogeochemistry, ecology, environmental engineering, or related field is required, as is a proven capacity to modify and run models and to design and manipulate large databases. The candidate should have strong interpersonal and organizational capabilities related to multi-investigator and large-scale studies. Experience with any of the following will be an asset: GIS, ecosystem modeling (CLM, CLM-CN, CASA, IBIS, DayCENT, etc), uncertainty analysis, or software engineering.”

Geographic Patterns of Hydrogen and Oxygen Isotopes in Human Hair

sci-policy-hd…from Science Insider

[Reaction about the scientific validity of a plan by the U.K. Border Agency to use DNA and isotope analysis of tissue from asylum seekers to evaluate their nationality and help decide who can enter the United Kingdom…]

Jane Evans, NERC Isotope Geosciences Laboratory: I can’t imagine how you use [isotope evidence] to define nationality….It worries me as a scientist that actual peoples’ lives are being influenced based on these methods.

James Ehleringer, University of Utah: In 2008 we published a paper establishing a relationship between the hydrogen and oxygen isotope of human hair and geographic patterns…To the best of my knowledge, we are the only laboratory that has taken the hair isotope patterns and explicitly placed them onto a GIS display (i.e., map). As you see from that map, there are not unique relationships in the USA, only banding patterns. I am unaware of any substantive regional and/or global pattern analyses other than those out of our lab. Thus, I find it surprising that scientists in the UK have not only acquired the data to develop global maps but also that this technique has been refined to the point that it is a viable, reliable screening tool with the specificity implicit in the document. There are not unique global distribution patterns for hydrogen and oxygen isotopes of water. Instead there are repeatable patterns across continents in a general sense. We would expect hair hydrogen and oxygen isotopes to exhibit the same pattern.  Thus, a unique specificity that would be appropriate for the proposed application seems unlikely. Now the additional analyses of heavy isotopes in hair may further constrain the possible regions of origin, but I do not believe that our science has reached the point where we can be specific at the country or within country scale.

“Now to the bigger challenge…Hydrogen and oxygen isotopes of hair reveal recent regional geographic patterns. Assuming that hair grows at about 1 cm per month,  a 10-cm hair length might record the last 10 months of that person’s travel…this 10-month period is not necessarily synonymous with where that person may have originated from.”

NOAA’s Free Habitat Digitizer Extension for ArcGIS

HabitatDigitizerMap“The Habitat Digitizer Extension is a GIS tool designed to use a hierarchical classification scheme to delineate features by visually interpreting georeferenced images such as aerial photographs, satellite images, and side scan sonar. The extension allows users to create custom classification schemes, digitize polygons, lines, and points using standard ArcGIS editing tools, and attribute the features using a dialog containing the user-created scheme. The extension allows new hierarchical classification schemes to be easily created, modified, and saved for use on future mapping projects. There are several advantages to using classification schemes with a hierarchical structure: the detail of habitat categories can be expanded or collapsed to suit user needs, the thematic accuracy of each category/hierarchical level can be determined, and additional categories can be easily added or deleted at any level of the scheme to suit user needs.

“This GIS tool has been useful in many benthic habitat mapping projects of the Biogeography Branch; see related project links below.”

Puget Sound Maps the Future of Renewable Energy

…from Vector One

“Washington State’s oldest local energy utility, Puget Sound Energy (PSE), adapted quickly with a program that rewards customers with qualifying renewable energy systems. PSE continues to push the envelope for innovative ways of thinking about renewable energy and conservation programs. The utility is recognized by the American Wind Energy Association as the second-largest utility owner of wind energy facilities in the United States and owns two commercial production wind power plants. PSE has garnered national recognition for a variety of energy efficiency achievements recently, including the prestigious platinum-level Energy and Water Management Award by the Secretary of the Navy and the U.S. Environmental Protection Agency’s 2009 ENERGY STAR for its efforts in energy conservation.

“PSE has been supplying energy to customers for more than 100 years and today serves more than 1 million electric and approximately 750,000 natural gas customers around the Puget Sound region. To meet the electrical energy needs of its customers over the next 20 years, PSE implemented a 2009 integrated resource plan that directs the utility to add 1,100 megawatts (MW) of renewable wind generation and 1,064 MW of efficient energy to its existing generation portfolio of hydroelectric, wind, gas, and coal power plants. As energy efficiency becomes a leading resource addition, the utility has to become more innovative in targeting customers with energy savings potential and increasing their engagement with its energy efficiency programs. Geographic information system (GIS) technology is playing an increasing role in refining PSE’s understanding of its customers and their potential efficiency gains.”
