Climate - Biogeochemistry Interactions in the Tropical Oceans (SFB 754)

Collaborators:Logo SFB 754

GEOMAR
several institutes at Kiel University

The Collaborative Research Center (SFB 754) addresses the relatively newly recognized threat of ocean deoxygenation, its possible impact on tropical oxygen minimum zones and implications for the global climate-biogeochemistry system. The overall goal of the SFB 754 is to improve understanding of the coupling of tropical climate variability and circulation with the ocean's oxygen and nutrient balance, to quantitatively evaluate the nature of oxygen-sensitive tipping points, as well as to assess consequences for the Ocean's future.

The importance of submarine groundwater discharge for the southwestern Baltic Sea (SGDBALTIC)Logo SGDBALTIC

Collaborators:
Alfred-Wegner Institute, Bremerhaven
Helmholtz Centre for Environmental Research, Leipzig

This project investigates the occurrence of submarine groundwater discharge in the southwestern Baltic Sea and the potential impact of SGD on the coastal environment (EU FP7 funded).

Transport and Fluxes across the benthic boundary layer – subproject within the special research project SFB 754 “Climate - Biogeochemistry Interactions in the Tropical Ocean” (further information: http://www.sfb754.de/en/?Home)


Groundwater/seawater along the south African coast and its effects on sustainable coastal and water resource management (SPACES).

Collaborators: Logo SPACES
Helmholtz Centre for Environmental Research, Leipzig (project coordinator)
Weihenstephan-Triesdorf University of Applied Sciences
Leibniz Institute for Baltic Sea Research, Warnemünde
Council for Scientific and Industrial Research, Western Cape, South Africa

This collaborative project investigates the groundwater/seawater interaction (GSI) along the South African south coast between False Bay and East London with the focus on the impact of groundwater discharge on coastal environments and its effects on marine biota. Furthermore the vulnerability of aquifers due to land use changes and due to groundwater overexploitation is studied (BMBF funded).

Biogeochemistry of trace metals and their isotopes in the southeastern Atlantic. RV Meteor cruise M121.M121

Principal investigators:
Prof. Dr. M. Frank
Prof. Dr. E. Achterberg
Prof. Dr. Andrea Koschinsky

This cruise is part of the internationally coordinated program GEOTRACES. The main goal of the cruise is to determine in detail the distributions of trace elements and their isotopes (TEIs) in the water column of the SE Atlantic in order to constrain TEI supply and removal mechanisms, their biogeochemical cycling, and their interaction with the nitrogen cycle in the study region. The focus of our group will be on the distribution radium isotopes to investigate the origin and fluxes of TEIs. (DFG funded).
