Water exchange in the Baltic Sea: a historical view of research approaches from basin scales to submesoscale

open access: yesFrontiers in Earth Science
At the beginning of the 20th century, Knudsen illustrated that the mean observed salinity of the Baltic Sea could be realistically estimated, assuming an inflow of saline Kattegat water equals the net freshwater supply, also called the Knudsen theorem ...

Heavy hydrogen in the stratosphere [PDF]

open access: yes, 2003
We report measurements of the deuterium content of molecular hydrogen (H2) obtained from a suite of air samples that were collected during a stratospheric balloon flight between 12 and 33 km at 40º N in October 2002. Strong deuterium enrichments of up to

High-resolution simulations of the final assembly of Earth-like planets 2: water delivery and planetary habitability

open access: yes, 2007
The water content and habitability of terrestrial planets are determined during their final assembly, from perhaps a hundred 1000-km "planetary embryos" and a swarm of billions of 1-10 km "planetesimals." During this process, we assume that water-rich ...
