Photo competition
At NAC there will be a photo competition. Every participant in NAC 2018 can submit one photo on any theme related to the broad field of earth sciences. To submit a photo for the competition, one must be registered for NAC 2018 (see terms and conditions). Submitted photos will be exhibited at the conference and are shown below (click on a photo to see more information).

Siberian sunset on our eddy covariance setup
Slow ice melt in the Arctic sea caused flooding up many of the major Arctic rivers, including at our eddy covariance site in Kytalyk Nature reserve in the NE Siberian tundra. We lost power to the setup, but it made for some spectacular scenery!

Oasis in the Desert

Soil pastrie
The photo tells the history of three different soil formations in northeastern Montana (USA) captured in one landform, in the shape of a pastrie. The oldest soil is the whitish bleached layer, right to the geologist. The white colour may be the product of downward leaching of iron-oxides during prolonged non-depostion at areas in between ancient river valleys. Overlying the leached soil, on top of the hill, is a younger soil formation represented by the black coal seam. The coal (compacted peat) reflects decades of peat accumulation in an ancient forested wetland. The youngest soil formation is currently going on. The exposed bleached layer and coal are barren and weathering therefore acts from all angles, shaping this rock as a pastrie.

All hands on desk/deck!
Here we see ‘all hands on deck’ a positive alternative to the 21st century’s ‘all hands on desk’. These scientists are drilling for peat cores below the North Sea. Coming out of the last glacial cycle, the rising seas eventually submerged the old island, Doggers Bank. An island with a peaty landscape, the peat growth itself can be used as a proxy of sea level rise. Furthermore, these scientists are checking for large reservoirs of trapped methane that, if released could significantly contribute to a warming climate. This is the first ever attempt of mapping sea level rise and trapped methane in the North Sea. A large network of participators rather than spectators is evidence of relevance and that those conducting the science are knowledgable, effective communicators and teachers. A good show is usually measured by the number of spectators but with this image, I propose, empty seats and participation, as a method of measuring good science.

Mysterious fossil creepy creature
An alien, predating our carbon based nature, testimony of a silica-based earth dweller, or the remains of a contemporary floater? This mask might allow us to experience new horizons that could show traces of primeval life based on ‘crystal genes’ (see ‘clay-life hypothesis’ by the late Mr. A .G. Cairns-Smith).

The saw blade damaged the now missing bottom side of the sagged outer envelope. Then the whole brittle structure, in- and outside, was consolidated by resin. Scale: 1 cm

Industrial ice
While the refueling lay-over at Goose-Bay, Canada, was obnoxious, and only the beginning of the transit-trouble I was about to experience due to the heavy snow-falls and strong winds, it did allow me to admire this terrific sight of the frozen rivers and lakes in the North of Canada. The shapes and patterns of tears in the ice were beautiful, and seemed industrial.

Framed forever
This picture was taken at the construction site of the parking garage at Vredenburg (Utrecht). The photo was taken during the process of collecting lacquer peels from Rhine deposits underneath the hearth of the city Utrecht. The lacquer has been applied to the sediment and is partially setting before the back of the lacquer peel is applied.

Wedding Cake
A mature supercell has been roaming across the high plains of eastern Colorado for over six hours. When a storm persists for such a long time, it has complete control of its surroundings and acquires incredible structure. The updraft base has become rain-wrapped and looks like a multi-layered column of clouds, which among storm chasers is occasionally referred to as a 'wedding cake'.
