Long-term persistence of the floating bull kelp Durvillaea antarctica

Long-term field experiments were used to evaluate the spatial (latitude) and temporal (season) effects on floating capacity and performance of D. antarctica.The in situ experiments were started during austral winter 2014 (July) and late spring-summer 2014/2015 (December) at each locality. These experimental sets were henceforth named as winter and

Solar forcing on antarctic terrestrial climate: A study by

With a view to difficulties with explaining the physical mechanism of solar forcing on the Earth''s climate, we applied a new approach of determining and quantifying an influence of solar-related events on water vapor variability by correlating the total electron content (TEC) and precipitable water vapor (PWV), both derived from ground-based GPS observations this

Renewables in Antarctica: an assessment of progress to

One of the first uses of solar energy in Antarctica was to heat water and melt ice. As solar PV panels became more efficient and cheaper, they began to be incorporated into the production of electricity in Antarctica. For example, Wasa Station (Sweden) uses solar energy to provide both heating and electricity.

Mapping Renewable Energy among Antarctic Research Stations

In Antarctica, the renewable-energy sources used in hybrid systems are wind or solar power, both of which are non-dispatchable. The use of non-dispatchable energy sources may be problematic, owing to potential rapid shifts in

A case study of relationship between GPS PWV and solar

Water vapor plays an important role in the global climate system. A clear relationship between water vapor and solar activity can explain some physical mechanisms of how solar activity influences terrestrial weather/climate changes. To gain insight of this possible relationship, the atmospheric precipitable water vapor (PWV) as the terrestrial climate

Long-term persistence of the floating bull kelp Durvillaea antarctica

The bull kelp raft samples found at King George Island in January 2017 and 2019 were assessed for evidence of viability, and many were found to be reproductively mature (Table S2; Fraser et al.8). Indeed, D. antarctica appears well suited to long-distance dispersal in sub-Antarctic and Antarctic waters; experimental research along the coast of

Mapping of sea ice production for Antarctic coastal polynyas

Active sea‐ice production in Antarctic coastal polynyas causes dense water formation, finally leading to Antarctic Bottom Water (AABW) formation. This study gives the first mapping of sea ice production in the Antarctic Ocean, based on heat‐flux calculation with ice thickness data derived from satellite data. The highest ice production occurs in the Ross Ice

Long-term observations of mean winds and tides in the upper

Southern hemisphere observations at 44°S, described by Fraser (1990), showed no solar cycle dependency of the mean zonal wind but possibly a decreasing semi-diurnal tidal amplitude with decreasing solar activity. The significance of this trend was relatively low given the limited amount of data used in the study. For Antarctic latitudes

Long-term evolution of the Sulzberger Ice Shelf, West Antarctica

In Antarctica, ∼75% of the Antarctic coastline is covered by ice shelves, which are floating extensions of the Antarctic Ice Sheet (Rignot et al., 2013).Mechanical disturbances triggered by tsunamis may have an impact on stabilities of these ice shelves (Bromirski et al., 2010, 2017; Surawy-Stepney et al., 2023).For instance, tsunami signals were found in a time

Solar energy explains fast yearly retreat of Antarctica''s sea ice

A research vessel in Antarctica on June 3, 2017, the first day researchers saw the sun rise above the horizon on their journey home after weeks of polar darkness. New research shows that solar radiation drives the relatively fast annual retreat of sea ice around Antarctica at the end of each calendar year.

Where is the first Australian solar farm in Antarctica?

Home > News and media > 2019 > First Australian solar farm in Antarctica opens at Casey research station The first Australian solar farm in Antarctica will be switched on at Casey research station today.

How many solar panels are there in Antarctica?

The first Australian solar farm in Antarctica was switched on at Casey research station in March 2019. The system of 105 solar panels, mounted on the northern wall of the ‘green store’, provides 30 kW of renewable energy into the power grid. That’s about 10% of the station’s total demand.

Can solar power be used in Antarctica?

Although advancements in technology are now making solar a more viable option for use in the polar regions, there is already a history of solar power supporting scientists in the Arctic and Antarctica. For example, the British Antarctic Survey’s Halley VI research station is powered by a combination of solar panels and wind turbines.

How does solar radiation affect Antarctica?

New research shows that solar radiation drives the relatively fast annual retreat of sea ice around Antarctica at the end of each calendar year. Ben Adkison In the Southern Hemisphere, the ice cover around Antarctica gradually expands from March to October each year.

What is solar power harvesting in Antarctica?

Introduction Solar power harvesting in Antarctica started in the early 1990s, when NASA and the US Antarctic Program tested PV at a field camp to generate electricity . Since then, the collected data have revealed that the installed capacity has increased to over 220 kWp nowadays.

Can solar panels run in Arctic and Antarctica?

In fact, some studies suggest that cooler temperatures can help solar panels run more efficiently. Instead, solar panels rely on solar radiation to produce energy. So, the question isn’t whether the Arctic and Antarctica are warm enough, but whether they get enough sun exposure. The fact is that we can use solar panels at the poles.
