    • On acoustic scattering by a shell-covered seafloor 

      Stanton, Timothy K. (Acoustical Society of America, 2000-08)
      Acoustic scattering by the seafloor is sometimes influenced, if not dominated, by the presence of discrete volumetric objects such as shells. A series of measurements of target strength of a type of benthic shelled animal ...
    • On dynamically consistent eddy fluxes 

      Berloff, Pavel S. (2004-11-04)
      The role of mesoscale oceanic eddies in driving the large-scale currents is studied in an eddy-resolving, double-gyre ocean model. The new diagnostic method is proposed, which is based on dynamical decomposition of the ...
    • On eddy viscosity, energy cascades, and the horizontal resolution of gridded satellite altimeter products 

      Arbic, Brian K.; Polzin, Kurt L.; Scott, Robert B.; Richman, James G.; Shriver, Jay F. (American Meteorological Society, 2013-02)
      Motivated by the recent interest in ocean energetics, the widespread use of horizontal eddy viscosity in models, and the promise of high horizontal resolution data from the planned wide-swath satellite altimeter, this paper ...
    • On estimating the number of species from the discovery record 

      Solow, Andrew R.; Smith, Woollcott K. (Royal Society, 2005-02-04)
      A common approach to estimating the number of species in a taxonomic or other group is to extrapolate the temporal pattern of historical species discoveries or descriptions. A formal statistical approach to this problem ...
    • On latency of multiple zonal jets in the oceans 

      Berloff, Pavel S.; Karabasov, S. A.; Farrar, J. Thomas; Kamenkovich, Igor V. (Cambridge University Press, 2011-09-27)
      Most of the nearly zonal, multiple, alternating jets observed in the oceans are latent, that is, their amplitudes are weak relative to the ambient mesoscale eddies. Yet, relatively strong jets are often observed in dynamical ...
    • On minimising assignment errors and the trade‐off between false positives and negatives in parentage analysis 

      Harrison, Hugo B.; Saenz-Agudelo, Pablo; Planes, Serge; Jones, Geoffrey P.; Berumen, Michael L. (2013-05)
      Genetic parentage analyses provide a practical means with which to identify parent–offspring relationships in the wild. In Harrison et al.'s study (2013a), we compare three methods of parentage analysis and showed that the ...
    • On non-stationarity of ENSO 

      Solow, Andrew R.; Huppert, Amit (American Geophysical Union, 2003-09-13)
      Evolutionary spectral analysis has been used to study changes through time in the variability of ENSO-related time series. However, the significance of estimated evolutionary spectra has not been formally assessed. This ...
    • On predicting abundance from occupancy 

      Solow, Andrew R.; Smith, Woollcott K. (University of Chicago Press, 2010-05-13)
      There is growing interest in predicting the abundance of a species in a region from the occupancy of cells in a uniform grid overlaid on the region. When the number of individuals in each cell follows a negative binomial ...
    • On rectification of randomly forced flows 

      Berloff, Pavel S. (Sears Foundation for Marine Research, 2005-05)
      Nonlinear rectification of the ocean circulation driven by random forcing, which simulates the effect of unresolved eddies, is studied in an idealized closed basin. The results are based on the analysis of randomly forced ...
    • On sea surface salinity skin effect iInduced by evaporation and implications for remote sensing of ocean salinity 

      Yu, Lisan (American Meteorological Society, 2010-01)
      The existence of a cool and salty sea surface skin under evaporation was first proposed by Saunders in 1967, but few efforts have since been made to perceive the salt component of the skin layer. With two salinity missions ...
    • On the Abyssal circulation in the glacial Atlantic 

      Marchal, Olivier; Curry, William B. (American Meteorological Society, 2008-09)
      An inverse method is used to evaluate the information contained in sediment data for the Atlantic basin during the Last Glacial Maximum (defined here as the time interval 18–21 kyr before present). The data being considered ...
    • On the acoustic diffraction by the edges of benthic shells 

      Stanton, Timothy K.; Chu, Dezhang (Acoustical Society of America, 2004-07)
      Recent laboratory measurements of acoustic backscattering by individual benthic shells have isolated the edge-diffracted echo from echoes due to the surface of the main body of the shell. The data indicate that the echo ...
    • On the attribution of a single event to climate change 

      Hansen, Gerrit; Auffhammer, Maximilian; Solow, Andrew R. (American Meteorological Society, 2014-11-15)
      There is growing interest in assessing the role of climate change in observed extreme weather events. Recent work in this area has focused on estimating a measure called attributable risk. A statistical formulation of this ...
    • On the bioeconomics of marine reserves when dispersal evolves 

      Moberg, Emily A.; Shyu, Esther; Herrera, Guillermo E.; Lenhart, Suzanne; Lou, Yuan; Neubert, Michael G. (2015-08)
      Marine reserves are an increasingly used and potentially contentious tool in fisheries management. Depending upon the way that individuals move, no-take marine reserves can be necessary for maximizing equilibrium rent in ...
    • On the boundary conditions applied to the sea-ice coupled model 

      Huang, Rui Xin; Jin, Xiangze (American Geophysical Union, 2007-04-06)
      The formulation of suitable boundary conditions at the water-ice interface during ice formation (melting) is an important aspect of the sea-ice coupled model. The transfer of water and salt through the water-ice can be ...
    • On the calculation of wind stress curl over open ocean areas from synoptic meteorological data with application to time dependent ocean circulation 

      Welch, Christopher Slocombe (Woods Hole Oceanographic Institution, 1972-02)
      The method used by N. P. Fofonoff for estimating wind stress curl from surface atmospheric pressure maps is developed for use with the National Meterological Center analysis grid. A formula is developed relating the wind ...
    • On the characteristics of Circumpolar Deep Water intrusions to the west Antarctic Peninsula Continental Shelf

    • On the circulation of Atlantic Water in the Arctic Ocean 

      Spall, Michael A. (American Meteorological Society, 2013-11)
      An idealized eddy-resolving numerical model and an analytic three-layer model are used to develop ideas about what controls the circulation of Atlantic Water in the Arctic Ocean. The numerical model is forced with a surface ...
    • On the connection between dense water formation, overturning, and poleward heat transport in a convective basin 

      Straneo, Fiamma (American Meteorological Society, 2006-09)
      An isopycnal, two-layer, idealized model for a convective basin is proposed, consisting of a convecting, interior region and a surrounding boundary current (buoyancy and wind-driven). Parameterized eddy fluxes govern the ...

      Zhai, Ping; Pratt, Lawrence J.; Bower, Amy S. (American Meteorological Society, 2015-05)
      The west-to-east crossover of boundary currents has been seen in mean circulation schemes from several past models of the Red Sea. This study investigates the mechanisms that produce and control the crossover in an idealized, ...
