The transmitter for certain channels could be located
at a lower elevation on the broadcast tower, or even behind other broadcast towers.
«Going into the study, we were sure that we would detect a functioning and viable microbial ecosystem in the permafrost soils of University Valley as we and others have done in Arctic and Antarctic permafrost, including in other sites
at lower elevations in Antarctica.
The advance increases the glaciers area
at low elevation where ablation is highest, returning the glacier to equilibrium.
A decade after a stand - replacement forest fire on the Metolius watershed in Central Oregon, almost no trees have begun to regenerate on one of the dry
sites at lower elevation.
24 21.2 World Climates Highland Climates In general, highland climates are cooler and wetter than nearby
areas at lower elevations.
Herbivore activity was
greater at lower elevations and higher temperatures and at high concentrations of foliar P, with up to 20 % of foliar productivity diverted to herbivores over the year.
We will hike 1 — 2 hours per day (1 — 2 miles) on uneven trails over moderate
grades at low elevations in hot and humid conditions.
Early in the melt season (April - June 15), ablation is dominated by
melt at the lower elevation range (> 1500m) in alpine basins (Pelto, 1996; Fountain and Tangborn, 1985).
There are scrub oak and Jeffrey
pine at the lower elevations, the latter smelling sweet and faintly of vanilla as they heat up in the bright sunlight.
The elevation of marsh species is important; those
species at lower elevations experience longer and more frequent tidal floods and therefore have the opportunity for more sediment deposition to occur.
A massive ice sheet almost completely covers Greenland, and as summertime temperatures climb and sunlight hours lengthen, parts of the ice sheet surface usually melt, especially
at lower elevations near the coast.
-- In larger
rivers at lower elevations, warming trends may result in more frequent fishing season closures and disease outbreaks, such as the mountain whitefish (Prosopium williamsoni) kill on the Yellowstone River in the fall of 2016 (MFWP 2016, Wright 2016).
This parasite is a problem in the Americas, the affected region stretching from the Gulf Coast and Eastern seaboard of North America,
especially at low elevations, into Quebec and Ontario.
Ablation peaks in May
at low elevation Snotel sites, in June at high elevation Snotel sites, and in August on glaciers.
That's almost 0.6 C
warmer at the lower elevation in the same city and the same weather at the same time, a similar shift to the Wellington St increase in the chart above.
High - altitude puzzles That's crucial because glaciers at the highest altitudes, where temperatures are more likely to stay below freezing, are behaving differently than their
counterparts at lower elevations.
But there were also more than 20 communities outside the park's boundaries that spent most of the year cultivating crops and raising
livestock at lower elevations.
They used some records from ponderosa pine and Douglas fir trees, which
thrive at lower elevations and in years with heavy snowfall.
Small
arrays at lower elevations have probed the sky since the 1980s, but atmospheric moisture made observations difficult at wavelengths shorter than 3 millimetres.
The great ice sheets of Greenland and Antarctica, which rise to over 13,000 feet above sea level, accumulate ice over most of their surfaces and melt
only at their lower elevations near the edges.
«Most glaciers have thinned several hundred
feet at low elevations in the last 40 years, and about 60 feet at higher elevations,» team member Keith Echelmeyer reports.
While the specific cause of the Yosemite toad's decline is unknown, meadow restoration across the high Sierras is of importance to land managers focusing on watershed health to maintain clean and sustainable water supplies for the
populations at lower elevations.
Ruiz, who contributed to the report, noted that an analysis of weather records at one páramo research station showed increases in minimum temperatures were almost twice that of lower elevations, while increases in maximum temperatures jumped to nearly three times the
average at lower elevations.
These plants tended to grow at sites experiencing less snowfall — such as
plots at lower elevations, or along ridges and slopes instead of coves and valleys, where snow tends to accumulate.
Like many mountain ecosystems, Niwot Ridge serves as an important «water tower,» regulating downhill water flow as snowmelt replenishes lakes and
streams at lower elevations.
The laser analysis yielded a composition very close to that of Mars soil and unlike the lakebed sedimentary compositions
observed at lower elevations and earlier in the mission.
First Klaus regales me with tales of a recent development drive of the 2017 NSX in the Alps, where the foremost challenge on the narrow mountain passes proved to be pavement slick with cow manure, as the farmers were busy bringing their cattle to new
pastures at lower elevations before the onset of winter.
