New Zealand's territory in the Antarctic, the Ross Dependency is justly famous for the diversity of its weather phenomena.
Imagine a world where summer means 24 hours of daylight, winter 24 hours of darkness – and between these two remarkable seasons, a feast of sunsets and sunrises the likes of which you will find nowhere else on earth.
After the relenting darkness and intense cold of the Antarctic winter, and two months of winter darkness in June and July, the sun gradually returns to this isolated region from early August onwards. The region then witnesses weather phenomena that are spectacular and dramatic. This is the Ross Dependency – a slice of the Antarctic under the stewardship of New Zealand.
From August to October, those people fortunate enough to be stationed at the Ross Island bases have the opportunity to observe – and photograph – hours of dramatic views as the sun skims along the horizon for hours on end, accentuating this ruggedly beautiful landscape. Breathtaking sunsets take place, punctuated by vicious blizzards that can rage for days at a time.
Delicate pink alpenglow illuminates the slopes of Mount Erebus, the active volcano that dominates Ross Island. This alpenglow looks warm and inviting but in fact October is the coldest time of year, with evening temperatures plummeting to as low as -40 degrees. To the south of New Zealand's research facility at Scott Base, the Black and White Islands are silhouetted against a ghostly yellow glow, and rugged ice towers push skyward in the Ross Sea, the pillars of sea ice around Ross Island painted in yellow evening light. Mother of pearl clouds (or nacreous clouds) occasionaly light up the night sky.
By November, the sun no longer sets and there is continual daylight through until February and it's not until autumn that the night skies return. At this time of year sea smoke forms over the waters of McMurdo Sound and the Ross Sea, reflecting the extreme temperature differences between the water (-1.9°C) and the air (-20°C).
Few people have the chance to witness these magical events. Though this issue you had the opportunity to see them for yourself.
