    Get PDF
    Cruise report of RV Kilo Moana cruise 1811 on the U.S. margin in the Gulf of Alaska, north Pacific Ocean. The National Oceanic and Atmospheric Administration (NOAA), on behalf of the United States Government, has a requirement to carry out mapping surveys of specific regions on the margins in the Gulf of Alaska, north Pacific Ocean in order to determine the detailed bathymetry of the margins. The data are required to support any potential claim for extended jurisdiction by the United States under United Nations Convention on the Law of the Sea (UNCLOS) Article 76. The requirement is for the collection and processing of full-coverage multibeam sonar data in water depths of approximately 1000 to 5500 m in order to precisely define the location of potential natural prolongations to the continent as defined under UNCLOS Article 76. As part of the NOAA-funded research program, University of Hawaii researchers oversaw data acquisition, and University of New Hampshire (UNH) researchers performed the cruise planning and oversaw processing and archiving of the data collected during the cruise. A full patch test was conducted in deep water in the immediate area prior to commencement of mapping. New sound-speed profiles were collected by 139 XBT casts whenever the sound speed at the transducer differed by more than 0.5 m/s. All soundings are within 0.5% (2 sigma) of water depth, based on cross-line checks. Positions were determined by corrected differential GPS-aided inertial navigation. Sound-speed profiles were calculated from an XBT cast calibrated to an XSV cast during a patch test performed on the cruise prior to data collection. Horizontal_Positional_Accuracy_Report: Horizontal positioning of the vessel was determined using Applanix POS/MV inertial motion unit (IMU) version 5 which was provided with wide-area satellite-based differential positioning using the built-in Fugro Marinestar service as well as GNSS G2 service. Positioning is accurate to better than 0.5 meters (at 95% confidence) during all surveying. All positioning is referenced to the WGS84 Datum. Vertical_Positional_Accuracy_Report: Depth errors are within +/-0.5% of water depth. Process_Description: Raw data are as recorded by Kongsberg Maritime SIS data acquisition system. Depth units: meters Reference ellipsoid: WGS-84 Projection: unprojected geographic longitude, latitude Vertical reference: instantaneous sea level

    A Deep Multicolor Survey. VI. Near-Infrared Observations, Selection Effects, and Number Counts

    Get PDF
    I present near-infrared J (1.25um), H (1.65um), and K (2.2um) imaging observations of 185 square arcminutes in 21 high galactic latitude fields. These observations reach limiting magnitudes of J ~ 21 mag, H ~ 20 mag and K ~ 18.5 mag. The detection efficiency, photometric accuracy and selection biases as a function of integrated object brightness, size, and profile shape are quantified in detail. I evaluate several popular methods for measuring the integrated light of faint galaxies and show that only aperture magnitudes provide an unbiased measure of the integrated light that is independent of apparent magnitude. These J, H, and K counts and near-infrared colors are in best agreement with passive galaxy formation models with at most a small amount of merging (for Omega_M = 0.3, Omega_Lambda = 0.7).Comment: AJ Accepted (Feb 2001). 28 pages, 7 embedded ps figures, AASTEX5.

    Dopamine D_2-receptor activation elicits akinesia, rigidity, catalepsy, and tremor in mice expressing hypersensitive 4 nicotinic receptors via a cholinergic-dependent mechanism

    Recent studies suggest that high-affinity neuronal nicotinic acetylcholine receptors (nAChRs) containing α4 and β2 subunits (α4β2*) functionally interact with G-protein-coupled dopamine (DA) D_2 receptors in basal ganglia. We hypothesized that if a functional interaction between these receptors exists, then mice expressing an M2 point mutation (Leu9'Ala) rendering 4 nAChRs hypersensitive to ACh may exhibit altered sensitivity to a D_2-receptor agonist. When challenged with the D_(2)R agonist, quinpirole (0.5–10 mg/kg), Leu9'Ala mice, but not wild-type (WT) littermates, developed severe, reversible motor impairment characterized by rigidity, catalepsy, akinesia, and tremor. While striatal DA tissue content, baseline release, and quinpirole-induced DA depletion did not differ between Leu9'Ala and WT mice, quinpirole dramatically increased activity of cholinergic striatal interneurons only in mutant animals, as measured by increased c-Fos expression in choline acetyltransferase (ChAT)-positive interneurons. Highlighting the importance of the cholinergic system in this mouse model, inhibiting the effects of ACh by blocking muscarinic receptors, or by selectively activating hypersensitive nAChRs with nicotine, rescued motor symptoms. This novel mouse model mimics the imbalance between striatal DA/ACh function associated with severe motor impairment in disorders such as Parkinson’s disease, and the data suggest that a D_(2)R–α4*-nAChR functional interaction regulates cholinergic interneuron activity.—Zhao-Shea, R., Cohen, B.

    Are megaquakes clustered?

    Full text link
    We study statistical properties of the number of large earthquakes over the past century. We analyze the cumulative distribution of the number of earthquakes with magnitude larger than threshold M in time interval T, and quantify the statistical significance of these results by simulating a large number of synthetic random catalogs. We find that in general, the earthquake record cannot be distinguished from a process that is random in time. This conclusion holds whether aftershocks are removed or not, except at magnitudes below M = 7.3. At long time intervals (T = 2-5 years), we find that statistically significant clustering is present in the catalog for lower magnitude thresholds (M = 7-7.2). However, this clustering is due to a large number of earthquakes on record in the early part of the 20th century, when magnitudes are less certain.Comment: 5 pages, 5 figure

    X-ray CT analysis after blast of composite sandwich panels

    Four composite sandwich panels with either single density or graded density foam cores and different face-sheet materials were subjected to full-scale underwater blast testing. The panels were subjected to 1kg PE4 charge at a stand-off distance of 1 m. The panel with graded density core and carbon fiber face-sheets had the lowest deflection. Post-blast damage assessment was carried out using X-ray CT scanning. The damage assessment revealed that there is a trade-off between reduced panel deflection and panel damage. This research has been performed as part of a program sponsored by the Office of Naval Research (ONR)
