The coastline along the southern Arabian Gulf between Al Jubail, Kingdom of Saudi Arabia, and Dubai, UAE, appears to have risen at least 125 m in the last 18,000 years. Dating and topographic surveying of paleo-dunes (43–53 ka), paleo-marine terraces (17–30 ka), and paleo-marine shorelines (3.3–5.5 ka) document a rapid, > 1 mm/a subsidence, followed by a 6 mm/a uplift that is decreasing with time. The mechanism causing this movement remains elusive but may be related to the translation of the coastal area through the backbasin to forebulge hinge line movement of the Arabian plate or, alternatively, by movement of the underlying Infracambrian-age Hormuz salt in response to sea-level changes associated with continental glaciation. Independent of the mechanism, rapid and episodic uplift may impact the design of engineering projects such as nuclear power plants, airports, and artificial islands as well as the interpretation of sedimentation and archeology of the area.

Surface exposure dating has become a helpful tool for establishing numeric glacial chronologies, particularly in arid high-mountain regions where radiocarbon dating is challenging due to limited availability of organic material. This study presents 13 newBe surface exposure ages from the Kitschi-Kurumdu Valley in the At Bashi Range, Tien Shan. Three moraines were dated to ~ 15, 21 and > 56 ka, respectively, and corroborate previous findings that glacial extents in the Tien Shan during Marine Oxygen Isotope Stage (MIS) 2 were limited compared to MIS 4. This likely documents increasingly arid conditions in Central Asia during the last glacial cycle. Morphological evidence in the Kitschi-Kurumdu Valley and a detailed review of existing numeric glacial chronologies from the Tien Shan indicate that remnants of the penultimate glaciation (MIS 6) are preserved, whereas evidence for MIS 5 glacier advances remains equivocal. Reviewed and recalculated exposure ages from the Pamir mountains, on the other hand, reveal extensive MIS 5 glacial extents that may indicate increased monsoonal precipitation. The preservation of MIS 3 moraines in the Tien Shan and the southern Pamir does not require any monsoonal influence and can be explained alternatively with increased precipitation via the westerlies.

Hot on the heels of my post about doing work in house, InfoWorld's Deep End column takes a look at build-vs-buy.
Relying solely on support contracts and generic solutions is a good way to self-limit the agility and performance of any business. In short, more gurus equals less hand-wringing and stress all around.In an era when software is eating the world, information agility is key to competitiveness (or, in government terms, "effective service delivery"), when competitors are investing heavily in brain power, why would any organization dumb itself down?

This study tests if burnt soils and sediments can provide reliable records of geomagnetic field strength at the time of burning by carrying out an experiment to reproduce the prehistoric use of fire on a clayish soil substratum. Rock magnetic experiments showed that in the upper 0–1 cm of the central part of the burnt surface, remanence is a thermoremanent magnetization carried by single-domain magnetite and that samples are thermally stable. Fourteen specimens from that area were subjected to paleointensity experiments with the Coe method (1967). An intensity of 42.9 ± 5.7 μT was estimated below 440°C, whereas at higher temperatures magneto-mineralogical alterations were observed. Corresponding successful microwave intensity determinations from two specimens gave a mean value of 47.6 μT. Both results are in reasonable agreement with the expected field value of 45.2 μT. Burnt soils of archeological fires thus have the potential to record accurately the paleofield strength and may be useful targets for archeointensity investigations. Coincident results obtained from two different paleointensity determination methods support this conclusion.

New pollen, micro-charcoal, sediment and mineral analyses of a radiocarbon-dated sediment core from the Serra Sul dos Carajás (southeast Amazonia) indicate changes between drier and wetter climatic conditions during the past 25,000 yr, reflected by fire events, expansion of savanna vegetation and no-analog Amazonian forest communities. A cool and dry last glacial maximum (LGM) and late glacial were followed by a wet phase in the early Holocene lasting for ca. 1200 yr, when tropical forest occurred under stable humid conditions. Subsequently, an increasingly warm, seasonal climate established. The onset of seasonality falls within the early Holocene warm period, with possibly longer dry seasons from 10,200 to 3400 cal yr BP, and an explicitly drier phase from 9000 to 3700 cal yr BP. Modern conditions with shorter dry seasons became established after 3400 cal yr BP. Taken together with paleoenvironmental evidence from elsewhere in the Amazon Basin, the observed changes in late Pleistocene and Holocene vegetation in the Serra Sul dos Carajás likely reflect large-scale shifts in precipitation patterns driven by the latitudinal displacement of the Inter-Tropical Convergence Zone and changes in sea-surface temperatures in the tropical Atlantic.

FY 2012 spending bills. Today, the House will move forward and vote on a motion to begin the conference on the Military Construction-VA (HR 2055) measure, which has been targeted as the vehicle for the nine spending bill omnibus package. Lawmakers hope to complete the conference as early as this Thursday. To achieve this, Congressional appropriators and leadership plan on including the eight other overdue appropriations bills on the Military Construction-VA spending bill which has already passed in both chambers. If successful, this approach would allow Congress to complete the FY 2012 appropriations bills before the current continuing resolution (PL 112-55) expires Dec. 16. Members of Congress from both sides of the aisle and upper and lower chambers have made predictions for the success of this approach ranging from impossible to very probable. Only time will tell if the legislative branch of our government can do its job. Stay tuned…
On 21 Nov, the Co-Chairs of the Joint Select Committee on Deficit Reduction, Representative Jeb Hensarling and Senator Patty Murray, released the following statement. "After months of hard work and intense deliberations, we have come to the conclusion today that it will not be possible to make any bipartisan agreement available to the public before the committee’s deadline. Despite our inability to bridge the committee's significant differences, we end this process united in our belief that the nation's fiscal crisis must be addressed and that we cannot leave it for the next generation to solve. We remain hopeful that Congress can build on this committee’s work and can find a way to tackle this issue in a way that works for the American people and our economy. We are deeply disappointed that we have been unable to come to a bipartisan deficit reduction agreement, but as we approach the uniquely American holiday of Thanksgiving, we want to express our appreciation to every member of this committee, each of whom came into the process committed to achieving a solution that has eluded many groups before us. Most importantly, we want to thank the American people for sharing thoughts and ideas and for providing support and good will as we worked to accomplish this difficult task.We would also like to thank our committee staff, in particular Staff Director Mark Prater and Deputy Staff Director Sarah Kuehl, as well as each committee member's staff for the tremendous work they contributed to this effort. We would also like to express our sincere gratitude to Dr. Douglas Elmendorf and Mr. Thomas Barthold and their teams at the Congressional Budget Office and Joint Committee on Taxation, respectively, for the technical support they provided to the committee and its members."
