    Fram Strait sea ice export variability over the last 80 years (2016)
    PANGAEA
    In:  Supplement to: Smedsrud, Lars Henrik; Halvorsen, Mari H; Stroeve, Julienne C; Zhang, Rong; Kloster, Kjell (2017): Fram Strait sea ice export variability and September Arctic sea ice extent over the last 80 years. The Cryosphere, 11(1), 65-79, https://doi.org/10.5194/tc-11-65-2017

    Description: A new long-term data record of Fram Strait sea ice area export from 1935 to 2014 is developed using a combination of satellite radar images and station observations of surface pressure across Fram Strait. This data record shows that the long-term annual mean export is about 880?000 km**2, representing 10 % of the sea-ice-covered area inside the basin. The time series has large interannual and multi-decadal variability but no long-term trend. However, during the last decades, the amount of ice exported has increased, with several years having annual ice exports that exceeded 1 million km**2. This increase is a result of faster southward ice drift speeds due to stronger southward geostrophic winds, largely explained by increasing surface pressure over Greenland. Evaluating the trend onwards from 1979 reveals an increase in annual ice export of about +6 % per decade, with spring and summer showing larger changes in ice export (+11 % per decade) compared to autumn and winter (+2.6 % per decade). Increased ice export during winter will generally result in new ice growth and contributes to thinning inside the Arctic Basin. Increased ice export during summer or spring will, in contrast, contribute directly to open water further north and a reduced summer sea ice extent through the ice?albedo feedback. Relatively low spring and summer export from 1950 to 1970 is thus consistent with a higher mid-September sea ice extent for these years. Our results are not sensitive to long-term change in Fram Strait sea ice concentration. We find a general moderate influence between export anomalies and the following September sea ice extent, explaining 18?% of the variance between 1935 and 2014, but with higher values since 2004.

    Comparison of the Ca+HF(DF) and Sr+HF(DF) reaction dynamics (1988)

    Notes: A comparative study of the reaction family, Ca and Sr with rovibrationally selected HF or DF, has been carried out under single-collision conditions. A thermal beam of the alkaline earth atoms, Ca or Sr, is fired into a low-pressure gas of HF or DF in which the reagent molecules have been prepared in a selected vibration–rotation state by the use of a tunable infrared light source (optical parametric oscillator). The resulting alkaline earth monofluoride reaction products, CaF or SrF, are detected in a quantum-state-specific manner with a tunable visible light source (dye laser) using laser induced fluorescence. The HF molecule is aligned with its rotational angular momentum pointing preferentially either along or perpendicular to the metal atom beam. For both Ca+HF(v=1) and Sr+HF(v=1) the cross section and the product state distribution are found to be independent of the approach geometry, which is consistent with reaction through a bent transition state. The state-to-state reaction dynamics for Ca+HF(DF) and Sr+HF(DF) show marked differences. The Ca+HF(DF)→CaF+H(D) reaction has attributes of a statistical internal energy distribution, whereas Sr+HF(DF)→SrF+H(D) shows some deviation from this behavior. The findings for Ca+HF(DF) are consistent with a model in which the Ca atom inserts into the HF bond to form a long-lived H–Ca–F intermediate; the findings for Sr+HF(DF) are interpreted as competition between direct reaction and reaction which samples the deep H–Sr–F potential well.

    AN IMPROVED METHOD OF CHOLESTEROL DETERMINATION IN EGG YOLK BY HPLC (1999)

    Notes: An improved method for cholesterol determination in egg yolk is reported in this paper. Egg yolk was first diluted. Cholesterol was then extracted with ether and petroleum ether, and quantified by reverse phase chromatography on a Zorbax ODS column (0.46 × 15cm, 5–6 μm) using a mobile phase of acetonitrile and 2-propanol (4:1) with a flow rate of 0.6 mL/min. A linear correlation was observed between cholesterol concentration at 0.05–0.40 mg/mL and its peak heights with a correlation coefficient of 0.9993 (n = 5). The average recovery was 98.9%, and detection limit was 0.02 mg/mL. No differences in cholesterol concentration were observed between egg yolk samples with and without saponification. Rapid and reproducible quantification of cholesterol in egg yolk can be completed with this simplified method.

    Temperature dependent quenching of A 2Σ+ NO between 215 and 300 K (1995)

    Notes: Collisional quenching of the v'=0 vibrational level of the A 2Σ+ state of nitric oxide has been studied over the temperature range 215 to 300 K for the collision partners CO2, O2, H2O, NH3, H2S, and NO itself. The pressure dependence of the time decay of laser-induced fluorescence furnished the quenching cross sections σQ. The temperature is measured in situ. For all colliders, σQ is large and increases as the temperature decreases; this includes NO and O2 which do not show a temperature dependence above 300 K. The temperature dependence of σQ for each collider can be adequately described by the simple attractive force model of Parmenter and co-workers. © 1995 American Institute of Physics.

    New design of the variable angle infrared spectroscopic ellipsometer using double Fourier transforms (2000)

    Notes: A new type of incidence-angle-variable infrared spectroscopic ellipsometer working in the 2100–10 000 wave number range has been designed and constructed. For the system, the analyzer and polarizer were driven by two microstepping motors having hollow shafts and rotating synchronously with a speed ratio of 2:1, i.e., A=2P. The incidence angle can be varied from 30° to 90° with an accuracy of 0.01°. The doubled Fourier transforms as both functions of the wave number and the azimuthal angles of the polarizer and analyzer were carried out and integrated in the system. Two sets of ellipsometric parameters measured in the experiment have been used to test the data self-consistency of the system. In data reduction, the error arising from the slight anisotropy of the stray light was corrected. In application, the complex dielectric function of the Au film was measured with a data accuracy better that 1% in the entire spectral range. © 2000 American Institute of Physics.

    Effect of reagent rotation on product energy disposal in the light atom transfer reaction O(3P)+HCl(v=2,J=1,6,9)→OH(v',N')+Cl(2P) (1991)

    Notes: A rovibronic-state-to-rovibronic-state experiment has been performed on the reaction O(3P)+HCl(v=2,J=1,6,9)→OH(v',N')+Cl(2P). The O(3P) atoms are produced with a known energy by photolysis of NO2. The HCl(v=2,J) molecules are prepared by IR excitation of thermal HCl using an optical parametric oscillator. All energetically accessible OH rovibrational product levels are probed by laser-induced fluorescence for each prepared HCl rotational level. The OH(v'=0,N') rotational distribution shows a dip at N'=11, the depth of which decreases with increasing HCl rotational excitation. The available energy of reaction is partitioned so that 40% appears as OH vibration (V'), 32% as OH rotation (R'), and 28% as product translation (T'). This energy partitioning does not change with HCl rotation, in contrast to the general expectation for light atom transfer reactions of approximate conservation of internal angular momentum (R→R'). A substantial vibrational inversion is observed, in agreement with the vibrational adiabaticity (V→V') expected for such reactions.
