RELATERTE DOKUMENTER

From Figure 1 it is apparent that two of the targets, T2 and T3, were thought to have small disruptive preferences relative to the remaining (and non-disruptive) T1, serving as

The impact of sea-ice processes on DC T since ice formation due to calcium carbonate precip- itation and dissolution (DC TCaCO3 : gray), bacterial respiration (DC TBR : red),

The presented data comprise ridge geometry, ice block dimensions from ridge sails, ice structure in the ridge and values on the ridge porosity and the degree of

In the absence of Mg(II) both major and minor groove binding are observed, while in the presence of Mg(II) the preferred binding site is the minor groove.. The minor groove

Further, thicker clouds will increase the relative difference between open water and ice with snow due to higher degree of backscattering; incident irradiance over the thick ice
