\section{Results}

\begin{itemize}
\item{Integrated $w_i\Delta\theta_i$}
\item{Interpolated $w$ and $\Delta\theta$}
\end{itemize}
\subsection{Endzone $\Delta\theta*<v>$}

A nearly synoptic characterization of the MEF hydrography is provided by an ABE
dive that occurred during (northward at what speed?) flow.  ABE surveyed the N
side of the MEF in ?? hr, transited to the S side in ?? min, and finished the S
side in ?? hr.  It then proceeded to complete the E and W sides.  The resulting
measurements of $\Delta\theta$ (projected onto the control surfaces in figure
\ref{control-volume}) show that the N side is warmer than the S side.

\subsection{Estimates of Instantaneous Lateral Heat Flux}

Address this question: Why can't NoSoMEF T fields from similar phases of tide
be used to estimate instantaneous flux? 

Compare puff model Dth to mean and variance Dth observations?

Discuss and quantify error propagation in HF calculations?  Especially relative to
the precision of the CTD and $\Delta\theta$...
