Cape Ochi-ishi Station is located at the eastern coast of Hokkaido, at the base of Nemuro peninsula.
The city of Nemuro (located ~20 km east, population 35,000) is the nearest city. Cape Ochi-ishi has a considerably cold climate with average yearly temperature of about 5°C. Most of the cape is marshland, designated as a nature preserve; the monitoring station is located at the southern tip of the cape, and is approximately 50 m above sea level.
Hourly measurements of halocarbons have been performed at Cape Ochiishi since 2006. A fully automated preconcentration/gas chromatograph/mass spectrometer system measures ~50 trace gases, including halocarbons.
