As part of the International Biological Program’s (IBP) Tundra Biome project at Barrow, Alaska, the microclimatic regimes of that region are being investi- gated. These sites were resampled by Webber, Craig Tweedie, Robert Hollister, Sandra Villarreal and others in 1999, 2008, and 2010, and assessed for community change by Villarreal as part of the 'IPY Back to the Future: Resampling old research sites to assess changes in high latitude terrestrial ecosystem structure and function project' (NSF Award No. Plot data reported in *_Single_Plots_1972.csv are for 10 plots not relocated in 1999 for repeated measurements. Subzone A (A), Subzone B (B), Subzone C (C), Subzone D (D), Subzone E (E), Treeless Oceanic Boreal (O), Forest-Tundra Transition (FT), Boreal (BO). Forty-three (43) plots were assessed for estimated percent land cover by species and plot data including moisture, topographic position, slope, aspect, shape, and soil data. Each vegetation plot consists of a 1 x 10-m belt with a 1-m x 10-cm strip along the inside. Floristic diversity near Barrow (ca. [5] All 200 residents were Inuit. 2. PhD thesis, The University of Texas at El Paso, El Paso, Texas, USA. In addition to the numerous data synthesis and analysis papers resulting from this repeating sampling activity, Webber also provided insight on the quality of these and other datasets collected using his plant community sampling method at the Alaska AVA Boulder Workshop (Webber 2014). The city's native name, Utqiaġvik, refers to a place for gathering wild roots. 1980, Webber 1978, Webber et al. Point Barrow is an important geographical landmark, mark… Tundra vegetation change near Barrow, Alaska (1972-2010). A region of tundra > 200,000 km2 in area, the arctic slope of Alaska has continuous permafrost, snow cover for 7-9 mo each year, and low relief (Britton 1966). cycle increased by 40% at Point Barrow, AK, and by 20% at Mauna Loa, HI over the period 1960–1993 [Keeling et al., 1996].

From the dense moss carpeted rainforests of southeast Alaska, to the wide-open expanses of the tundra on the North Slope these ecosystems and provide habitat for a variety of fish and wildlife species. Arctic Vegetation Plots for IBP Tundra Biome, Barrow, Alaska, 1972-2010. The Barrow IBP vegetation plot data have been extensively analyzed, updated, and published. 1) is situated near Barrow, Alaska (71018'N, 156042'W). Note that functional type percent covers for 2010 were calculated from species cover data by Sandra Villarreal (2012). Ground-based research and models suggest that release of this carbon as permafrost thaws is going to accelerate global … natural vegetation (NAT) or anthropologically disturbed (DIS). CAFF Proceedings Report #11. The six-sided monument honors pioneer Wiley Post and comedian and homespun philosopher Will Rogers who died in 1935 when their plane went down 15 miles southwest of Barrow during a flight to Seberia. ISBN: 978-9935-431-29-5. The location has been home to the Iñupiat, an Indigenous Inuit ethnic group, for more than 1,500 years. Plot numbers are the same each year. Two of the major Landmarks in the tundra biome are in Alaska, The first is Million Dollar Bridge, it was built in the early 1900's, it's also called The Miles Glacier Bridge, and got its name from the cost to build it which was 1.4 million dollars. Nome’s precipitation levels hit 18.4 inches. On the flip side, the northerly U.S. city called Point Barrow, experiences annual precipitation levels of 4.3 inches. Direct link to the plot archive record in the Arctic Geoecological Atlas: http://agc.portal.gina.alaska.edu/catalogs/10178-alaska-arctic-vegetation-archive-barrow-vegeta. Archaeological evidence indicates that Point Barrow was occupied by the ancestors of the Iñupiat for almost 1,000 years prior to the arrival of the first Europeans. Temperature for the warmest months in the arctic tundra ranges from 3-12° C (37- 57° F). Point Barrow is an important geographical landmark, marking the limit between two marginal seas of the Arctic Ocean, the Chukchi Sea to the west and the Beaufort Sea to the east.[1].

This observatory includes a central facility at Barrow (known officially as Utqiaġvik) and, to the east, the third ARM Mobile Facility at Oliktok Point. One file (.csv format) provides above- and below-ground biomass and leaf area index (LAI) data for a wet arctic tundra meadow (Biome research site 2, Dupontia meadow, vegetation type V) studied from 1970 to 1971 at Point Barrow, Alaska, USA, (71.30 N -156.67 W Elevation 5 m).

ABoVE seeks a better understanding of the vulnerability and resilience of ecosystems and society to this changing environment. It reported 152 residents, of which 143 were Native, 8 were "other race" and 1 was White. There are still summer cabins constructed by locals and used for subsistence hunting and fishing in this area. Climate data in this data set are from the weather station at Barrow, Alaska (71.30 N 156.78 W) at an elevation of 31 m. The study plots for biomass measurements in 1970-1971 were 6 m x 6 m in size. These data are available through the Oak Ridge National Laboratory (ORNL) Distributed Active Climate change in the Arctic and Boreal region is unfolding faster than anywhere else on Earth. R.F. For example, could be land management unit, national park, or mountain range. Will specify the source of the name in the previous field. Figure 1. Country code generated by Turboveg. Point Barrow, a headland nine miles from town, is where the Chukchi and Beaufort seas meet. Forty-three sites, or plots, were originally established in 1972 and were used to characterize 10 plant communities for the IBP project including: 2) Arctophila fulva pond margin (2 plots), 4) Cochlearia officinalis pioneer meadow and creek bed (2 plots). The North Slope of Alaska (NSA) atmospheric observatory is providing data about cloud and radiative processes at high latitudes.
