回顾2015年，《国家地理》（National Geographic）过去一整年每天都在官网刊登一张照片，将之称为「每日一图」（Photo of the Day），照片的来源可能是该杂志的摄影记者，或者网路社团「Your Shot」成员的作品，到了年底，当然回顾一年的照片，挑选出20张最佳「每日一图」。
今天我们看到的照片张张精采，20张最佳「每日一图」中有13张是「Your Shot」成员作品，包括用Go Pro拍摄的企鹅张嘴疯狂照也入选，「Your Shot」成员Clinton Berr在南极研究企鹅时，捕捉到这超逗趣的画面，原来企鹅一点都不温驯！让我们看看其他精采照片。
Wikipedia : Phytoplankton are the autotrophic components of the plankton community and a key factor of oceans, seas and freshwater basin ecosystems. Most phytoplankton are too small to be individually seen with the unaided eye. However, when present in high enough numbers, some varieties may be noticeable as colored patches on the water surface due to the presence of chlorophyll within their cells and accessory pigments such as phycobiliproteins, xanthophylls, etc.) in some species.
Last night’s aurora borealis in Iceland with moonlight.
Cabo Pulmo, Baja, Mexico. Amazing example of what a Marine Protected Area can do. The fish biomass in this reserve has bounced back and the ecosystem is returning to a healthy state.
Taken a few days ago at the Apostle Island Ice Caves. Part of the beauty of this place is the silence of it. You hear nothing except the occasional creaking of the ice (which can make you jump if it’s right under you – lol) There were a few times when I just stopped and enjoyed the quiet … In this spot the only sounds were the water drops splashing.
The photo was taken along the frozen shores of Lake Superior at the Apostle Islands National Lake Shore near Bayfield Wisconsin. You can only reach the location by walking across a frozen Lake Superior, which does not happen often. Access was limited to only 9 days this past winter. The entire shore is beautiful, but what drew me to this particular ice flow was how the setting sun was shining through the ice giving it a soft yellow glow. I could hear the water dripping down the flow here, and was captivated not only by the view but the sounds. I thought the sun through the opening would make for a nice composition. As I was framing the shot another hiker came into view, which helped with scale and added interest for me. It was a quiet moment is a beautiful place.
Taken at Jellyfish Lake – a marine lake located in Eil Malk, which is part of Palau’s famous Rock Islands, a UNESCO World Heritage Site. These jellyfish populated marine basins thousands of years ago through rock fissures and gradually became isolated in an environment devoid of predators. In the absence of predators, these jellyfish evolved into having substantially less stinging cells.
This photo was taken in February 2015 on Lake Baikal. In ety photo expedition goal was to show the Baikal ice particular and unusual.
