Temperature Logs for Steamboat Geyser
Steamboat, located in Norris Geyser Basin, is one of Yellowstone's most famous geysers. Eruptions occur sporadically, but are well worth the wait. Columns of hot water reach heights up to 100 meters. This is followed by a raucous steam phase that can last for over a day, loudly discharging steam nearly 200 meters into the atmosphere.
Steamboat has proven more active during the early 21st Century than any time since the early 1980s. Between late 1991 and 2000, there were no eruptions. However, since May 2000, Steamboat has erupted 7 times... most recently on May 23, 2005.
The last 8 eruptions of Steamboat Geyser occurred on:
12 October 1991,
2
May 2000 (shown in image), 13 September 2002, 26 April 2002,
26 March 2003, 27 April 2003, 22 October 2003, and 23 May 2005.
Yellowstone Park staff monitor the outlet channel Steamboat Geyser. The temperature logs record the interesting "preplay" of water leaving Steamboat's vent and entering its runoff channel.
There are two sets of data: Steamboat Channel and Steamboat Boardwalk.
The file names represent the feature (SB or SC, the year and the
month).
About the data:
The data columns represent the following:
j2ksec: seconds after Jan 1, 2000
date and time: YYYY-MM-DD hh:mm:ss.sss
temp: Temperature in degrees centigrade
Please note: The time is in UTC (Greenwich mean time). To convert to Mountain Standard time (MST) you need to subtract 7 hours. To convert to Rocky Mountain Daylight time (MDT) you need to subtract 6 hours. Each file represents one month, starting at midnight MST on the first day of the month. Thus they start at 7:00 AM UTC.
