I. Intro: IA. Heat flux context and history of measurement IB. Regional hydrography: Figure idea: -- akin to Thurnherr 3.2 -- sig2 vs depth showing decreased N near axis -- relative to E and W (and other?) background stations -- is there a E-W or S-N density gradient that implies that a Nward or Wward mean flow is favored? IC. ID. II. MEF heat flux III. Advected MEF heat flux: puff model insights IV. Tidal flows and heat flux measurment V. Implications and future work VI. References Appendices...
