Studies on lichen-dominated systems. VIII. The instrumentation of a raised-beach ridge for temperature and wind speed measurements
The instrumentation of a research site on a raised-beach ridge, 5 km inland from Hudson Bay, is described. Fine thermocouples and hot-film anemometers were used to measure air and thallus temperature, and wind speeds, respectively. Replicate sensors were monitored through automatic stepping switches...

| Summary: | The instrumentation of a research site on a raised-beach ridge, 5 km inland from Hudson Bay, is described. Fine thermocouples and hot-film anemometers were used to measure air and thallus temperature, and wind speeds, respectively. Replicate sensors were monitored through automatic stepping switches of new design and strip chart recorders. The circuit diagram of the stepping switch is described. The satisfactory operation of the entire system indicates that it is not difficult to maintain this type of electronic equipment in remote sites and opens up considerable possibilities for ecological work in fairly inaccessible areas. |
