The high productivity off Peru is driven by the complex interplay between upwelled nutrients and the amount of nutrients recycled by remineralisation processes in the OMZ. However, surprisingly little is known about organic matter cycling and its effects on biogeochemical processes in the OMZ. To this end, we will conduct a first comprehensive biogeochemical study on the role of organic matter for the biogeochemical processes (incl. the nitrogen cycle) and the maintenance of the OMZ. The proposed cruise will be performed as part of a third phase of the SFB754 \u2018Climate-Biogeochemistry Interactions in the Tropical Ocean\u2019 (<a href=\"http:\/\/www.sfb754.de\" target=\"_blank\" rel=\"noopener noreferrer\">www.sfb754.de<\/a>).<\/p>\n<p>Chief scientist are Herman W.

Ihr Thema: Die Sauerstoffminimumzone (OMZ) im tropischen S\u00fcdostpazifik. Sie\u00a0 ist eng mit dem K\u00fcstenauftriebssystem vor Peru verkn\u00fcpft. Die daraus resultierende hohe biologische Produktivit\u00e4t vor Peru wird durch das komplexe Zusammenspiel von frisch-aufgetriebenen N\u00e4hrstoffen und die Menge an N\u00e4hrstoffen, die durch Remineralisierungsprozesse in der OMZ freigesetzt werden, gesteuert. Jedoch ist \u00fcberraschend wenig \u00fcber die Remineralisierung von organischem Material und dessen Auswirkungen auf die biogeochemischen Prozesse in der OMZ vor Peru bekannt. Deshalb werden wir eine erste umfassende biogeochemische Studie zur Untersuchung der Rolle des organischen Materials f\u00fcr die biogeochemischen Prozesse (wie z.B. den Stickstoffkreislauf) und die Ausbildung der OMZ vor Peru durchf\u00fchren.<\/p>\n<p>Die Fahrt ist Teil des von der Deutschen Forschungsgemeinschaft gef\u00f6rderten <a href=\"http:\/\/www.sfb.754.de\" target=\"_blank\" rel=\"noopener noreferrer\">Sonderforschungsbereichs 754 &#8220;Klima-Biogeochemische Wechselwirkungen im tropischen Ozean&#8221;<\/a>.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The oxygen minimum zone (OMZ) in the eastern tropical South Pacific is tightly connected to the coastal upwelling system off Peru.
