Journal Sullivan, F. Barrow, Alaska July 30 (at) 2 juvenile longparr. Pitelka and I tried out the pin drop apparatus behind the lab. The braces kept the meter stick too high above ground. The pins would not reach to the soil surface. Pitelka suggested fiping this first and then trying later this afternoon. Chamberlain and I lowered the overall height of the apparatus to 21 cm. After lunch Pitelka and I measured transects - 2 meter each and surveyed them with the pin-drop ap. method: 1. Place end of p.d. ap. against stake. 2. Drop pin to surface of ground. 3. Record all vegetation touched by the point of the pin as it descends. Record as to species and whether tiving or dead. 4. Continue 3 above at each 5 cm interval. We surveyed the 5 transects this afternoon. Weather turned cooler and overcast in late afternoon. Tundra is wet when one kneels or squats to do the above work. July 31 Rained hard last night and early this morning. Checked snap-trap lines: captured 2 juvenile Lemmus. The rain had sprung a majority of the traps and it took 3 hours to reset them. It was still raining, windy and cold while working on the lines (0800-1100). Cleared around moon and then a very strong wind sprang up.
