This all could apply to anybody, so my 2 scents:
Any suggestions for the following would be really helpful:
1. Tips for collecting data-- for example, I noticed that in some
Gazers' data books, they have abbreviations, which makes it easier
and quicker to write down times. I think things happen quickly at the
Silver Globes (from my unofficial observations) as the functions
change between each one.
If you were sitting right there taking the data, then I wouldn't expect any
standard abbreviations to be necessary (that is, you probably wouldn't be
using i.e for "in eruption," or n.s. for "near start," and etc. On the other
hand, there would be nothing wrong with you inventing of some kind of personal
shorthand for use only when recording things.
Things do happen quickly at the Silver Globes, so recording times to
the second would be desirable. Doing it "to the whole minute" would likely miss
some relationships. When I do that sort of thing, I usually write down the
hour only for the very first entry, then continue with minutes:seconds.
2. How long should I stay to get a good picture of what's going on
there? I am not sure I can dedicate an entire day--Lynn, you say "a
few hours". would three hours be about right? Less? More?
This of course depends on what is being studied. In the case of Silver
Globe, then three hours might actually be a bit short -- to me, the control there
would be the frequency of Slit Geyser. Any decent study of that complex ought
to include several Slit eruptions, and sometimes it goes quite a while
between eruptions.
For another example, for something like an update on the activity of
Slide Geyser, three hours would probably be excessive. And boring.
3. Should I watch nearby geysers, too, such as Jewel? Or just
concentrate on the ones I am writing about? There's a nice view of
the Old Road Group from there, I do plan to bring my binoculars!
Not necessary, and certainly I wouldn't look so far afield as the Old Road
area -- unless, of course, something new (rejuvenated Baby Daisy or some such)
was going on. I would also say that any reasonable observation of Jewel would
need eruption time _and_ number of bursts. And watching that could easily
cause you to miss something at Silver Globe.
4. Anything else? I do plan to have a couple of seasoned Gazers read
through the article before publication.
Remeber the modern understanding of names there, as recently discussed here
-- Silver Globe [SG] is the blue pool below (south of) the boardwalk (it is
simply Silver Globe, no "Spring" or "Geyser" or "Pool" in the name); Silver
Globe Cave Geyser [C] is right below the walk to the left (east) of Silver
Globe; Silver Globe Pair Geyser [P] is the pair of holes beyond Silver Globe; and
Slit Geyser [S] (Silver Globe is no longer part of its name) is beyond Pair.
On the other side of the boardwalk, Silver Globe Geyser [GG] is the thing in
the deep hole; BBG-3 [3] is to its east; Avoca Spring [A] is the elongated
spring north of Silver Globe Geyser.
OK, so shorthand again: as necessary, you could probably note the
geysers with the letters that I placed within brackets in the above.
