Hydrochemistry measured on water bottle samples in the northern Benguela during SONNE cruise SO283
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 Angola-Benguela Front regions. The fieldwork took place during the cruise No. SO283 (March 19st - May 25st, 2021) onboard the R/V SONNE...
