Tidal Modulation of Two-layer Hydraulic Exchange Flows : Volume 3,...

By: A. McC. Hogg; L. M. Frankcombe

Description: Research School of Earth Sciences, The Australian National University, Canberra, Australia. Time-dependent, two layer hydraulic exchange flow is studied using an idealised shallow water model. It is found that barotropic time-dependent perturbations, representing tidal forcing, increase the baroclinic exchange flux above the steady hydraulic limit, with flux increasing monotonically with tidal amplitude (measured either by height or flux amplitude over a...

By: K. Haines; V. N. Stepanov; H. Zuo; M. Valdivieso

Description: ESSC and Dept. of Meteorology, University of Reading, Reading, RG6 6AL, UK. Large-scale ocean transports of heat and freshwater have not been well monitored, and yet the regional budgets of these quantities are important to understanding the role of the oceans in climate and climate change. In contrast, atmospheric heat and freshwater transports are commonly assessed from atmospheric reanalysis products, despite the presence of non-conserving data assim...

Description: Scripps Institution of Oceanography, 9500 Gilman Drive, La Jolla, CA 92093, USA. The concentration of dissolved oxygen in seawater is routinely measured using a standardized titration method that involves analysis shortly after the water sample has been collected. However, none of the existing procedural documents are specific about how soon after collection the titration has to be done. Here, we report on a small number of samples where...

How Does Ocean Ventilation Change Under Global Warming? : Volume 3...

By: F. Zeng; J. L. Russell; A. Gnanadesikan

Description: NOAA Geophysical Fluid Dynamics Laboratory, Princeton, NJ, USA. Since the upper ocean takes up much of the heat added to the earth system by anthropogenic global warming, one would expect that global warming would lead to an increase in stratification and a decrease in the ventilation of the ocean interior. However, multiple simulations in global coupled climate models using an ideal age tracer which is set to zero in the mixed layer and ages at 1 yr/yr...
