1986_2003gsbbag - Nitrogen mineralization was determined on LTER and Sag River tussock tundra using the buried bag method. Yearly bags have been deployed every August since 1990.
-
1987_2002gsext - Plant available NH4, NO3, and PO4 was determined at sites near ARC LTER Toolik acidic tundra and at a toposequence along the floodplain of the Sagavanirktuk River using 2 N KCL and weak HCL extracts. This file complies data collected at different times from 1987 through 2001 and includes initial extracts taken for buried bag method of net nitrogen mineralization.
-
1991gsext - Extractable NH4-N and NO3-N (2 N KCl), PO4-P (0.025 N HCl) and pH (0.01 M CaCl2) were measured on soils from a transect along the Dalton road. Sites are Gus Shaver flowering sites and Arctic LTER sites.
-
1993gsbulk - Carbon, nitrogen and phosphoruscontent in thawed soils are described for four arctic tundra vegetation types located near the Toolik Field Station.
-
1993_to_currentsoilthaw - Late season thaw depth was measured in the ARC LTER experimental plots (Moist Acidic Tussock, Moist Non-acidicTussock, Moist Non-acidic Non-tussock, Wet Sedge) at Toolik Lake, AK using a thaw probe.
-
1997lgextnuts - Plant available NH4, NO3, and PO4 was determined at three site (LTER Toolik acidic tundra, LTER Toolik nonacidic tundra, and Sagwon acidic tundra) and three community combinations (tussock, watertrack, and snowbed), three times during the season. pH was also determined in July and strong acid phosphorous in August.
-
1997shextsoilcats - Extractable soil cations (K, Ca, Mg, Na) for intertussock O and B horizon soils on moist acidic and non-acidic tundra.
-
1997shtotsoilnuts - Total soil cations (Al, Ca, K, Mg, Na, P) for intertussock O and B horizon soils on moist acidic and non-acidic tundra.
