25 November 2015
On Wednesday, November 25, 2015, at 41˚44’N, 71˚17’W over the course of a 20 hour period, I conducted a durational/observational performance. I marked and measured the various water-lines achieved throughout the day as the water receded from high tide, returned again and receded once more. Artifacts of the performance include a log book (transcribed), tide marking posts, photographs (digital contact sheet pictured), and a 95 foot string.
6:44am (sunrise), 22˚Fahrenheit. +5.8 feet* (first high tide)
7:44am, 27˚Fahrenheit. no data
8:44am, --˚Fahrenheit. +4.55 feet
9:44am, 39˚Fahrenheit. +2.3 feet
10:44am, 45˚Fahrenheit. +1.175 feet
11:29am (zenith). All of the shadows of the posts line up.
11:44am, --˚Fahrenheit. +0.05 feet
12:35pm, --˚Fahrenheit. -0.0333... feet (low tide)
Despite low tide occurring at 35 minutes past the hour measurements will still occur on every 44th minute of the hour, for accuracy, or consistency.
1:44pm, --˚Fahrenheit. 89 feet**
2:44pm, 46˚Fahrenheit. 71 feet
3:44pm, --˚Fahrenheit. 64 feet
4:09 to 4:14pm (sunset), no data.
4:44pm, --˚Fahrenheit. 44 feet
4:55pm (moonrise), --˚Fahrenheit.
5:44pm, --˚Fahrenheit. 22 feet
Post 5 has fallen over, knocked over by the surf. It has knocked over post 11 with it. Both posts float to shore.
Post 7 has fallen now too. It turns up later, 114 feet west.
6:44pm, --˚Fahrenheit.. 12 feet
7-7:17pm, --˚Fahrenheit. No data (second high tide).
I do not measure. I wait. The water will recede again.
* Measurements are given as the amount the water has dropped from the horizontal zero point of 5.8 feet (the expected high tide for the day)
** Measurements post-low tide are given as the distance the waterline is from the zero marker point (the high-tide waterline)
