Talk:Physical oceanography

message: Coriolis section mentions that "A slope of one part in one million in sea surface height, for example, will result in a current of 1 cm/s at mid-latitudes. "
I get that it should be 10cm/s as follows:
Use geostrophic relation fu=(1/rho) dp/dy
To get that u = (1/f*rho) dp/dy
And at the surface pressure is given by p=rho g eta where g is gravity and eta is sea surface height. Substitute in above expression to get current as
u =  (g/f) d eta / dy = 10^5 10^{-6} = 0.1 m/s
Here f is a mid latitude Coriolis parameter such that  g/f =10^5. I'm pretty sure this is correct so I am changing the article.  — Preceding unsigned comment added by 174.30.6.72 (talk) 21:04, 24 December 2015 (UTC)

thread_title: a note

message: OK - so it just got nominated, mis-read that one. Anyway, I've added an outline of sorts for your filling or chopping or whatever. 
I feel the Chemical oceanography article could easily be merged here, but this if developed via this collab. should be separate from the Oceanography overview article. Enjoy - I may be back later to do some fill-in, providing no one strenuously objects to the organization. Vsmith 00:54, 16 September 2005 (UTC)
thread_title:  Collab. of the week - nominee 

message: This section seems to be getting a bit too tactical in nature, and I though it would be better to merge the specific current entries with the Ocean current page. This section could then just be a general overview of what is in the main article. Thoughts? — RJH 20:24, 16 January 2006 (UTC)
thread_title:  Ocean currents 

message: Removed the following from section:
:The biosphere concept concerns life-supporting zones impacted by physical oceanography factors. The thickness of the biosphere on earth is hard to measure. Birds typically fly at altitudes of 650 to 2000 meters and fishes that live deep underwater can be found down to -8,372 meters in the Puerto Rico Trench. 
Not sure that it fits here - esp with the depth limit of the PR trench. Seems more appropriate for Marine biology. Vsmith 01:40, 20 January 2006 (UTC)

message: Congratulations to everyone involved. This article has really amazingly improved since becoming Science Collaboration of the Week. Keep it smart, and let us know when you come across other articles similarly needing help! Best, Samsara contrib talk 10:18, 27 January 2006 (UTC)
thread_title:  Well done! 

message: Oceanography is an important subject requiring attention on Wikipedia.  Many articles require cleaning up and expansion, and there are many missing articles.  Some standardization would be helpful.  Is there any interest in forming an Oceanography WikiProject?  It would be an undertaking, so it's important that there be enough interest to maintain it, but it is something that should happen when possible.  Looking to other WikiProjects for ideas and for illustrating the power of projects to improve areas is helpful, some related WikiProjects I'm involved in that have improved things greatly are Meteorology, Tropical cyclones, and Climate change.

message: At Sea level rise one primary source under review uses the concept of "interior water".  Can any page editors here explain what that is?  Thanks.   The source is this one NewsAndEventsGuy (talk) 12:12, 8 September 2018 (UTC)
replies: text: I cannot locate a technical meaning in a glossary. However,the meaning is the subsurface.SeeScripps website In Carl Wunsch'
Modern Observational Physical Oceanography on p. 83 he writes "The surface and near-surface ocean are complicated 
places...Surface waves which dominate the kinetic energy at the sea surface, span scales from millimeters to 
kilometers..." For him the interior water might mean the ocean below a mile to the benthic.Here the 
meaning of interior water is that which is below the air-sea interface. Church of the Rain (talk) 02:38, 28 September 2018 (UTC)
replies: text: I must be misreading Wunsch. The subsurface is not a mile down even though Wunsch confines the sea surface temperature to meteorology rather that oceanography. The interior waters mean waters below a couple hundred meters or 600 feet.  See NASA website Quoting (Wunsch, 2015, p. 84): "The ocean surface layer is subject to forcing by the atmosphere via winds, atmospheric pressure loads, evaporation, and precipitation.These processes also transfer gases...important in biology and climate. In high winds, such as hurricanes, the air-sea interface itself can vanish, becoming a continuum of air and water." I think oceanographers speak of the interior waters as those beyond the reach of these atmospheric processes.Church of the Rain (talk) 12:37, 28 September 2018 (UTC)
