Having so little land mass means that there are _much_ fewer opportunities for erosion beds where one can easily look for fossils. You have to use, perhaps, short sonar/radar and hunt for such things in oceanic shallows. Much less convenient. -=Will _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com *************************************************************************** To unsubscribe from this list send mail to majordomo@lists.ient.com with the line 'unsubscribe blue_planet' as the body of the message.

The distances at which British Columbian divers could clearly decern another diver varried form 0 to 85 feet. The average was about 30-40 feet or 10 meters. I don't know what depth this was at. In short visibility underwater is extremely limitted. I know more specific information is fairly widely available, I just don't have it to hand right now. If somebody knows the depths at which various colours fade due to the non-penetration of lightrays of those wave-lengths I would be grateful. --dave ----- Original Message ----- From: James Kiley To: Sent: Tuesday, July 17, 2001 11:36 AM Subject: [BLUE PLANET] - Possibly idiotic question > > So, in a typical chunk of Poseidon ocean, what's the visibility like at > various depths?

They theorised that the great red spot is stable because it gobbles up other storms, and never burns itself our because it never crosses land, hence it is constantly fed from the energy of the fluides below it. Now, given that there is no large land mass for a hurricane to burn out on, would there not be a constant, perminant storm somewhere in the belt?, perhaps in the northern hemisphere, where there is even less land. How fast such a "buckle" on the storm belt would move, I have no idea. Since storms are (I believe) linked to coriolis effect, then such a storm may not be able to cross the equator, so it would remain north of the equator. Areas of shallows may also reduce the storms intensity. Anyone here with more knowledge on this? Thanks, H __________________________________________________ Do You Yahoo!?

The MG, I believe, already mentions some storms that do that. And yes, it's more likely in the northern stormbelt, because of less land. Still, there are a number of instabilities. The land does warp storm systems, which cascade to warp other storm systems, etc. Coastal shallows will breed storms, which can disrupt and scatter other storm systems. Coastal shallows breed El Nino effects and tradewinds, which will also interfere with storm systems. A storm tracking west along the equator will hit an upsurging storm system on the eastern sides of shelves. This can cause it to loose energy as rain, even if there is no actual land there. The shallows themselves cause an atmospheric elevator (as hot damp air rises). Hmm. So to recap, where there are shallows, storms will tend to gain energy but also get scattered north and south. If they veer too far north or south, they hit arid weather systems at 40 degrees, which sucks their energy. If they keep going, they run into anticyclones at about 55 degrees, which also disrupts them. -=Will _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com *************************************************************************** To unsubscribe from this list send mail to majordomo@lists.ient.com with the line 'unsubscribe blue_planet' as the body of the message.
