musick, perhaps you can confirm this? I believe seiche is specific to a type of wave in a lake -- that is, you wouldn't have a seiche in the ocean.
I can't speak to the cause of a seiche, but I believe that one of its characteristics is that it oscillates back and forth across the lake.

from Bean's great list -- fetch
I think an another meaning of fetch (beyond what rkay notes) was discussed in the novel The Perfect Storm. [Anyone have a copy handy?] As I recall, the fetch of a wind is the distance it travels over water: the longer the fetch, the larger the wave it will build up. For that reason, even the largest waves on lakes are nowhere near the size of major ocean waves.

spring tide: When the sun, moon and earth are aligned. neap tide: When at right angles the forces are not aligned. The time between spring and neap is approximately 7 days. Here's a link to a Coastal Navigation site with a marvelous animated illustration, chart, and full tidal story: http://www.sailingissues.com/navcourse6.htmlFrom the site: The earth is also in orbit around the sun (one turn in one year) creating not only another centrifugal force but also a gravitational interaction. These two yield a bulge on the night site (centrifugal) and bulge on the day site (gravitational) both of them moving as the world turns. Therefore, a certain place on this world will experience two high and two low tides each day. With these forces alone, we would not have spring tides and neap tides. Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range (difference in water level between high and low tide) is much larger in a spring tide than in a low tide. The Only WO'N!

tombolo:
A coastal feature that forms when a belt sand and/or gravel is deposited between an island and the mainland. This feature is above sea-level for most of the time.
swash:
A thin sheet of water that moves up the beach face after a wave of water breaks on the shore.

mav's berm: Merriam Webster on-line: berm: a narrow shelf, path, or ledge typically at the top or bottom of a slope; also : a mound or wall of earth
edit: you sneaky thang, DJ! - and you got me thinking with your 'missing link' that you were saying there's no such usage context...

mav's bermMeanwhile, the version I was most familiar with was that of barriers around gun emplacements from interest in the Napoleonic Wars. I know, I know - I should get out more!Did ya click the photo link, mate? The Only WO'N!

>Once you are no longer close-hauled then you're not fetching any more, but veering towards a tight reach (some other time!)rkay you cad!!! Who you calling unfetching and no longer close-hauled.  ____________________________________________ Jackie, I always thought a thermocline was not just a difference in temperature of the water but the visible line that is created where the different waters are separated. I find that the line is a lot easier to see in a lake where there is much less wave action than in the ocean. Most often the waters even have different clarities. __________________________________________ W'ON when did you stop being our Happy Epeolatrist? When did your epeolatricity start waning? Poor sweet thing.

STOP!!!Well I read a entire book about berms. Remember about a hundred topics and five minutes ago yall were talking about berms? Berms are ,as defined by the people who study them, the strips of land that border the sides of a river or creek with topography and eco-systems directly interlinked to the effects of the stream. And doubledamn, I had something important to say about the "coriolis effect" but now I've forgotten it. Oh well...

the photo link, mate?yeah - thanks, very... Napoleonic Milum, isn't the main feature of <berminess> simply describing a bank or mound, and its specific context then determines what other features may apply? and tho' I don't get out enough and do read a *lot, I think I can proudly boast I haver *never read a complete book about berms
