Many ocean microbes have the genetic potential of consuming taurine, a key organosulfur compound, but it is unclear how this activity is linked to the worldwide decline in oxygen levels. Here, we found by 13C-DOS qSIP that taurine was only used as a C source in hypoxic waters of the Mariager Fjord.

This photo was taken in 1911 using glass plate technology by Herbert Ponting who was part of Scott's Antarctic expedition, The composition and detail are exquisite with the band of white snow/ice creating a perfect frame around the two people and the ship in the distance Iconic imo
Photograph from 1911 taken by Herbert Ponting whilst with Scott's Antarctic Expedition

The monochrome photo is taken from within a cave. The walls of the cave are made of ice. The cave entrance is in the mid distance with two figures standing looking out towards a distant ship. Between them and the ship there is first a 'beach' of ice before the sea itself. The ship could be up to 800 metres away

What makes the photo so special is that where the figures are at the cave entrance there is a band of very white snow and ice (contrasting with the comparatively dark inside of the cave) that creates a stark framework in which the men and the ship are captured. It is made even more dramatic by the fact that the cave entrance is at least 30 metres high and is in the shape of a distorted elipse with the tail sloping off to the right at the top of the elipse

The photo being in monochrome in a largely white environment makes the photographers skill all the more laudable
