Stable isotopes, Mg/Ca ratios and sea surface temperatures on foraminifera fr...
The complex deglacial to Holocene oceanographic development in the Gulf of Guayaquil (Eastern Equatorial Pacific) is reconstructed for sea surface and subsurface ocean levels... -
Respiration rate and ammonium excretion data for the squat lobster Pleuroncod...
Sampling was conducted during RV Meteor cruise M93 in austral summer 2013 in an area from 11ºS to 14ºS and approximately 120 km offshore to within 10 km of the Peruvian coast.... -
Nitrogen fuelling of the pelagic food web of the Tropical Atlantic
We estimated the relative contribution of atmospheric Nitrogen (N) input (wet and dry deposition and N fixation) to the epipelagic food web by measuring N isotopes of different... -
Mixed layer heat and salinity budgets during the onset of the 2011 Atlantic c...
The mixed layer (ML) temperature and salinity changes in the central tropical Atlantic have been studied by a dedicated experiment (Cold Tongue Experiment (CTE)) carried out... -
Nitrogen cycling driven by organic matter export in the South Pacific oxygen ...
Oxygen minimum zones are expanding globally, and at present account for around 20-40% of oceanic nitrogen loss. Heterotrophic denitrification and anammox-anaerobic ammonium... -
Oxygen variance and meridional oxygen supply in the Tropical North East Atlan...
The distribution of the mean oceanic oxygen concentration results from a balance between ventilation and consumption. In the eastern tropical Pacific and Atlantic, this balance... -
Nitrogen fixation and nitrogen gene abundance of METEOR cruises M77/3 and M77/4
Nitrogen fixation, the biological reduction of dinitrogen gas (N2) to ammonium (NH4+), is quantitatively the most important external source of new nitrogen (N) to the open... -
Nitrogen isotope, total organic carbon and element concentration data for pis...
Piston core M77/2-024-5 was retrieved during the M77/2 cruise of Research Vessel Meteor in December 2008. Total organic carbon concentrations were determined using a Carlo Erba... -
XRF-scanned elemental concentrations from sediment cores off Peru
We present a high-resolution marine record of sediment input from the Guayas River, Ecuador, that reflects changes in precipitation along western equatorial South America during... -
Zooplankton data of M83/1
Oxygen-deficient waters in the ocean, generally referred to as oxygen minimum zones (OMZ), are expected to expand as a consequence of global climate change. Poor oxygenation is... -

Oxygen-deficient waters in the ocean, generally referred to as oxygen minimum zones (OMZ), are expected to expand as a consequence of global climate change. Poor oxygenation is... -
Tracer release experiments in the tropical North Atlantic
Lateral diffusivity is computed from a tracer release experiment in the northeastern tropical Atlantic thermocline. The uncertainties of the estimates are inferred from a... -
Benthic foraminiferal denitrification rates and nitrate storage
The discovery that foraminifera are able to use nitrate instead of oxygen as energy source for their metabolism has challenged our understanding of nitrogen cycling in the... -
Mn/Ca and Fe/Ca systematics in benthic foraminifera from the Peruvian OMZ
In this study we present an initial dataset of Mn/Ca and Fe/Ca ratios in tests of benthic foraminifera from the Peruvian oxygen minimum zone (OMZ) determined with SIMS. These... -
Distribution of neodymium isotopes and concentrations during M77/3 and M77/4
The radiogenic isotope composition of the Rare Earth Element (REE) neodymium (Nd) is a powerful water mass proxy for present and past ocean circulation. The processes... -
Nitrogen isotope gradients off Peru and Ecuador related to upwelling, product...
We present new nitrogen isotope data from the water column and surface sediments for paleo-proxy validation collected along the Peruvian and Ecuadorian margins between 1°N and... -
