  • This work has followed two themes: (1) Developing and using the adjoint of the MIT ocean biogeochemistry model to examine the efficiency of carbon sequestration in a global configuration. We have demonstrated the power of the adjoint method for systematic ocean model sensitivity studies. We have shown that the relative efficiency of carbon sequestration in the Atlantic and Pacific basins changes with the period of interest. For decadal to centennial scales, the Pacific is more efficient. On longer timescales the Atlantic is more efficient . (2) We have developed and applied a high-resolution, North Atlantic circulation and tracer model tomore » investigate the role of the mesoscale in controlling sequestration efficiency. We show that the mesoscale eddy field, and its explicit representation, significantly affects the estimated sequestration efficiency for local sources on the Eastern US seaboard.« less
  • An integral part of designing low-level waste (LLW) disposal pits and their associated closure covers in very dry desert alluvium is the use of a radon gas transport and fate model. Radon-222 has the potential to be a real heath hazard. The production of radon-222 results from the radioactive decay (a particle emission) of radium-226 in the uranium-235 and 238 Bateman chains. It is also produced in the thorium-230 series. Both long lived radionuclides have been proposed for disposal in the shallow land burial pits in Area 5 RWMS compound of Nevada Test Site (NTS). The constructed physics based modelmore » includes diffusion and barometric pressure-induced advection of an M-chain of radionuclides. The usual Bateman decay mechanics are included for each radionuclide. Both linear reversible and linear irreversible first order sorption kinetics are assumed for each radionuclide. This report presents the details of using the noble gas transport model, CASCADR9, in an engineering design study mode. Given data on the low-level waste stream, which constitutes the ultimate source of radon-222 in the RWMS, CASCADR9 is used to generate the surface flux (pCi/cm{sup 2}-sec) of radon-222 under the realistic atmospheric and alluvial soil conditions found in the RWMS at Area 5, of the NTS. Specifically, this study examines the surface flux of radon-222 as a function of the depth of burial below the land surface.« less
  • The Subseabed Disposal Project (SDP), managed at and in part conducted by Sandia National Laboratories (SNL) for the US Department of Energy, is designed to evaluate the scientific, technical, environmental and economic feasibility of depositing high-level nuclear wastes (HLW) within the sediments at the bottom of the deep ocean. The work is in part to assist US planners in devising and assessing global disposal options, and in part to assist other nations in assessing the feasibility and consequences of oceanic nuclear waste disposal. At the schematic level, there appear to be many advantages to ocean disposal. First, the sites undermore » consideration are some of the most stable geological formations on the face of the earth, far from the active edges of tectonic plates and generally composed of thick sedimentary layers many millions of years old and many thousands of square kilometers in area. They are generally near the centers of the main oceanic circulation gyres and are therefore remote from the principal oceanic current systems. The deep sediments can be penetrated to 30 m or more meters at burial, and form thereafter an effective first barrier. Most of the radioactive nuclides which would eventually leak from the burial containers are permanently trapped in the sediments by chemical adsorption. As the deep sediments are anomalously poor in biological and mineral resources, radioactive decomposition of the sorbed nuclides promises to be relatively innocuous. Low deep-water temperatures (approx.1/sup 0/C) and high pressures (approx.500 atms.) provide an excellent environment for heat dissipation. Lastly, the sites are geographically remote and are rarely visited by seafarers of any kind. 55 refs.« less
  • Previous studies of perennial plants in the Northern Mojave Desert indicated that leaves of several of them had cation contents two or more times in excess of that of most agricultural plants. The purpose of the present study was to compare the cation-anion status of three such plant species from the Mojave Desert when grown under semicontrolled conditions with additions of three different anion carriers of Na. In the native condition, one of these species is not an accumulator of Na and the other two are. The leaves of the species not accumulating Na usually contain around 6% Ca whenmore » grown under field conditions so that all three species are high in total cations.« less
  • This report presents tentative innovations to enable unmanned vehicle guidance for a class of off-road traverse at sustained speeds greater than 30 miles per hour. Analyses and field trials suggest that even greater navigation speeds might be achieved. The performance calls for innovation in mapping, perception, planning and inertial-referenced stabilization of components, hosted aboard capable locomotion. The innovations are motivated by the challenge of autonomous ground vehicle traverse of 250 miles of desert terrain in less than 10 hours, averaging 30 miles per hour. GPS coverage is assumed to be available with localized blackouts. Terrain and vegetation are assumed tomore » be akin to that of the Mojave Desert. This terrain is interlaced with networks of unimproved roads and trails, which are a key to achieving the high performance mapping, planning and navigation that is presented here.« less
