Abstract: This study was motivated by the need to combine vertical derivative estimates of either potential density or temperature with SOFAR float data for estimating vortex stretching in the main (700 m) and lower thermocline (1300 ...

Abstract: This paper introduces a new approach, contour analysis, for combining independent estimates of a geophysical field to produce a single realization incorporating data from all sources. Contour analysis divides the field ...

Abstract: The terms in the Lagrangian potential vorticity equation are estimated by three different methods using clusters of SOFAR floats in the main (700 m) and lower (1300 m) thermocline of the POLYMODE region. The Lagrangian ...

Abstract: The authors present a numerical method for the inverse Lagrangian prediction problem, which addresses retrospective estimation of drifter trajectories through a turbulent flow, given their final positions and some knowledge ...

Abstract: The present study provides a consistent and unified theory for the three types of linear waves of the shallow-water equations (SWE) in a zonal channel on the ? plane: Kelvin, inertia?gravity (Poincaré), and planetary ...

Abstract: The recently developed ideas of generalized linear stability theory for dynamical systems are applied to time evolving flows of the Gulf Stream using a quasigeostrophic numerical model. The potential for the growth of ...

Abstract: A recipe for a cubic B-spline-based solution for multivariate variational formulation of a data analysis and assimilation problem is provided. To represent a signal whose smallest wavelength is L, the spline scale must be ...

Abstract: The first Lagrangian Analysis and Predictability of Coastal and Ocean Dynamics (LAPCOD) meeting took place in Ischia, Italy, 2?6 October 2000. The material presented at LAPCOD 2000 indicated both a maturing of Lagrangian-based ...

Abstract: The historical dataset provided by 700-m acoustically tracked floats is analyzed in different regions of the northwestern Atlantic Ocean. The goal is to characterize the main properties of the mesoscale turbulence and to ...
