The IBP study area was active between 1970 and 1973, and focused on a study area near Barrow, Alaska at the northernmost point on the Alaskan Coastal Plain (71°18'N 156°40'W) in close proximity to both the Chukchi and Beaufort Seas. Study Area (All latitude and longitude given in decimal degrees). The water around it is normally ice-free for two or three months a year, but this was not the experience of the early explorers. Over thousands of years, the remains of plants (and animals) that never fully decomposed have become part of the frozen soil in Alaska, Canada, northern Europe, and Russia. Run at Point Barrow in April 2019 Methods for quantifying pH vary. The North Slope of Alaska (NSA) atmospheric observatory is providing data about cloud and radiative processes at high latitudes.

In the early 1950s investigations by the U.S. Geological Survey (Brewer 1958) demonstrated the influence of lakes, ocean and buildings on near-surface permafrost temperature regimes and illustrated the characteristic zero curtain during the annual freeze-thaw cycles of 1951 and 1952.

Precipitation in tundra biome cannot exceed 10 inches per year, but there are notable exceptions. Even before the climate changes of the past decade, sea ice near Barrow has rarely been a solid, unbroken sheet stretching to the limitless horizon. Original data from 1972 were classified and community descriptions were published as a report (Webber & Ebert 1973) and as a component of IBP books (Brown et al.

Point Barrow or Nuvuk is a headland on the Arctic coast in the U.S. state of Alaska, 9 miles (14 km) northeast of Utqiaġvik (formerly Barrow).

Below-ground NPP was estimated from below-ground biomass (Webber, 1978) and from longevity of below-ground plant parts (Shaver and Billings, 1975; Billings et al., 1978). There is also a companion file with plot photos, often these photos document multiple sampling events. The mean average temperature vary according to location, with temperatures of -12° C (10° F) in Point Barrow, Alaska located at (71.3 ° N) to -28° C (-18° F) at the Northern region of Greenland (71° N). 2013, Walker and Raynolds 2011).
