The problem takes a volume of water that can be represented as a three-axis array. The X and Y directions have a modulus of 500, the Z 20. We then need to access this volume by specifying any two X,Y,Z points to extract data that represents acoustic transmission loss between the specified points. The data returned would be a vector of sound amplitudes and time delays. An array of frequency vs transmission loss might also be required for each point.
The number of elements for a fully populated array is huge (2.5e+13). There are ways to reduce the number of elements, maybe by the sources being in a smaller patch than the receivers. It might also be possible to use a polar grid about each source coordinate with perhaps 50 radials. It's thought that the total array size could be pared to 10-TB or less.
It is very interesting that so much specific information is posted. Do we all have to be killed now?
Since I was just today in the car listening to an article in audible.com's version of scientific american... My vote is modeling sound in widely varying ocean conditions to see if it's really possible that navy sonar or other man made noise from generic shipping is really killing whales? -- Brian K.
