Image of the Week – Antarctica’s Summer Solstice

♫ Antarctica’s Summer Solstice It’s winter in the northern hemisphere, but in Antarctica, summer has just begun. At Zucchelli Station the summer solstice occurred
on December 22nd, 2019 at 5:19pm local time. The high temperature that day
was a balmy 34 degrees Fahrenheit. These images from Landsat 8
show the distinct difference in sun angles cause by
the change in seasons. The September image is from
close to the equinox, shadows are longer, causing
the scene to be darker overall while revealing the ruggedness
of the mountains. The December image
is brighter, with shorter shadows and
much less sea ice. Landsat images are useful
for monitoring changes to the sea ice and glaciers
on the frozen continent. ♪♪♪ ♪♪ ♪
