This work writen in French describes the Dutch zoological and hydrographic expedition to Indonesia from March 1899 to February 1900 which was headed by Max Carl Wilhelm Weber. During the expedition, Weber, has found manganese nodules on one spot between the islands of Letti and Timor, at a depth of 1224 metres, in a mud containing a strong proportion of terrigenous material, far from being a pelagic deposit as was expected by the preceeding results...

Underway (U)CTD data were collected during an August-September 2018 expedition to the Arctic Ocean aboard the RV Akademik Tryoshnikov, and was a joint expedition between the German-Russian project CATS (Changing Arctic Transpolar System) and the US-Russian project NABOS (Nansen and Amundsen Basin Observing System). The UCTD was operated mostly in yoyo-mode during selected transects between the shelf and the basin across the continental slope of the Eurasian Basin while the ship was transiting with 8...

To investigate the history of vertical movements in Mauritania, 22 samples were collected from the Precambrian crystalline basement, which sporadically outcrops 100 to 500 km east of the shoreline of the Atlantic margin. The large majority of the samples were taken from granitic intrusions exposed in the Reguibat Shield in the north and along the N-S trending Mauritanides belt.

We present the new Atmospheric Raman Temperature and Humidity Sounder (ARTHUS). We demonstrate that ARTHUS measurements resolve 1) the strength of the inversion layer at the planetary boundary layer top, 2) elevated lids in the free troposphere during daytime and nighttime, and 3) turbulent fluctuations in water vapor and temperature, simultaneously, also during daytime. Very stable and reliable performance was demonstrably achieved during more than 2500 hours of operations time experiencing a huge variety of...

This dataset includes daily summaries of weather, snow, and preferential-flow conditions at the Snow and Ice Research Center, Nagaoka (Japan) -- snow seasons 2006 through 2018.The summary comprises 29 candidate predictors (features) of preferential flow as estimated by a weather-snow station, manual snow pits, and a snow model (SNOWPACK) and four metrics of preferential-flow characteristics measured by a multi-compartment lysimeter made by nine 1-m2 cells (standard deviation of mean snowpack runoff, coefficient of variation of...

In contrast to the vigorous deep ocean circulation system of the north- and southwestern Atlantic Ocean, no systematically sampled datasets of dissolved radiogenic neodymium (Nd) isotope signatures exist to trace water mass mixing and provenance for the more restricted and less well ventilated Angola Basin and the Cape Basin in the southeastern Atlantic Ocean, where important parts of the return flow of the Atlantic Meridional Overturning Circulation are generated. Here, to improve our understanding of...

Fterr = fraction of terrestrial organic carbon (Fterr), which is calculated from the Norg/Corg ratio.MT Index = index for the variable input of terrigenous versus marine organic matter.

Ocean acidification (OA) has potential to affect marine phytoplankton in ways that are partly understood, but there is less knowledge about how it may alter the coupling to secondary producers. We investigated the effects of OA on phytoplankton primary production, and its trophic transfer to zooplankton in a subtropical eutrophic water (Wuyuan Bay, China) under present day (400 μatm) and projected end-of-century (1000 μatm) pCO2 levels. Net primary production was unaffected, although OA did lead...
