Hydrochemistry measured on water bottle samples in the northern Benguela duri...
We present data on distribution of inorganic nitrogen compounds i.e. nitrate, nitrite and ammonium, and also phosphate and silicate in the northern Benguela and the... -
Porewater analyses from Meteor cruise M157 multicores and gravity cores
Porewater analyses from all M157 multicores and gravity cores are presented here. For each site, both shipboard and shore-based analyses are included. Shipboard analyses include... -
Physical oceanography on the Namibian Shelf obtained by CTD measurements duri...
The focus of hydrographic investigations during the cruise was on the impact of short term upwelling variability on oxygen and nutrient supply to the shelf, and on the response... -
Trace gases air daily means during METEOR cruise M157
The high surface productivity triggered by nutrient-rich Benguela upwelled waters results in significant enrichment of organic carbon in the sub-surface waters due to enhanced...
