Microbial and abiotic nitrous oxide cycling in the water column of meromictic, iron-rich Lake La Cruz, Spain, 2015-2017

Jana Tischer, Jakob Zopfi, Claudia Frey, Andreas Brand, Kirsten Oswald, Corinne Jegge, Caitlin H Frame, María R Miracle, Xavier Sòria-Perpinyà, Eduardo Vicente & Moritz F Lehmann
We investigated the microbial and abiotic N2O cycle in the water column of iron-rich, meromictic Lake La Cruz, Spain, during two sampling campaigns in March 2015 and March 2017. At the deepest point of the lake, we used a profiling in situ analyzer equipped with several probes and optodes to detect physicochemical parameters. In addition, we collected water column samples via an in situ pump in order to analyze concentrations of N, S, and Fe...

This dataset contains the results of the fluorescent dissolved organic matter characterisation (FDOM) and water mass optimum multiparameter analysis from the MAFIA cruise (Migrants and Active Flux In the Atlantic ocean). Samples were collected in the tropical and subtropical Atlantic during the MAFIA cruise (April 2015) on board the BIO Hespérides. Seawater samples for biogeochemical analyses were collected at 13 stations (from the Brazilian coast to the Canary Islands), from the surface down to 3500...

Late Cretaceous cyclostratigraphy for the subtropical western South Atlantic, Espírito Santo Basin

Thiago Pereira dos Santos, Fellippe Roberto Alves Bione, Igor Martins Venancio, M C Bernardes, Andre L Belem, Luana P Lisboa, Daniel R Franco, Rut A Díaz, Manuel Moreira, Noele F Leonardo, Igor V Souza, André L D Spigolon & Ana Luiza Albuquerque
Well-log data was acquired in a Late Cretaceous section of the Espírito Santo basin (western South Atlantic). Cyclostratigraphic techniques were used to explore the eventual pacing of orbital cycles in the deposition of sequences. The frequency ratio method was used to interpret the orbital cycles and based on this a long-eccentricity signal was interpreted and extracted to create a floating time-scale. Using a seismic horizon associated Cretaceous-Paleogene transition, a strong shift in the natural gamma-ray...

Chemical composition of deep sea manganese deposits determined at Kennecott Corporation during the 1967-1969 period

James E Andrews & Günther Friedrich
During the 1967-1968 period chemical analysis of both major and trace elements was performed on manganese nodules, crusts and micronodules on a large number of cores taken by the Lamont-Doherty Observatory during various cruises of the R/V Vema and the R/V Robert D. Conrad. Methods of analysis were a combination of Wet chemistry and Atomic Absorption Analysis (AAS). Most of the samples are related to buried deposits inside sediment columns. This data was released to...

Kay Helfricht, Clemens Hiller, Andrea Fischer & Stefan Achleitner
Discharge monitoring based on water level and surface velocity measurements was established at the Getschner bridge across the Jambach stream on 25 June 2019. This gauging station is located at an elevation of 2010 m a.s.l. and provides continuous data for the avalanche-free season, which usually lasts from June to November. Over this period, the station covers the runoff pattern from the onset of high mountain snowmelt in spring until the discharge stagnates again at...

Finn Süfke, Marcus Gutjahr, Lloyd D Keigwin, Brendan T Reilly, Liviu Giosan & Jörg Lippold
In this dataset we present new high resolution Pb isotope data alongside elemental concentration and ARM (anhysteretic remanant magnetization) data for four core sites in the arctic Mackenzie Delta area as well as the Amundsen Gulf. Cores were recovered with a piston corer during USCGC Healy cruise HLY1302. Cores are characterized by high sedimentation rates of up to 1 m/ka and reach back until 15 ka and therefore the late Heinrich Stadial 1. We also...

Carola Ferronato, Valeria A Guinder, Maria Paz Chidichimo, Celeste López-Abbate & Martín Amodeo
The species composition and structure (e.g. abundance and biomass) of protistan plankton (cell size > 5 µm) and in situ chorophyll a were assessed in a shallow (<50 m depth) inner shelf area of the Argentine Shelf called El Rincón (38º-41°S). Surface water samples (5 m depth) for plankton quantification were taken with Niskin bottles during four oceanographic cruises (two in early austral spring and two in late austral summer- early fall), onboard the vessel...

Forest canopy microclimate regulation during the drought year 2018 at the Leipzig Canopy Crane site

Ronny Richter
Tree canopies are considered to effectively buffer climate extremes and to mitigate climate change effects. Droughts, which are predicted to become more frequent in the course of climate change, might alter the microclimatic cooling potential of trees. However, our understanding of how microclimate at the tree canopy level is modulated by environmental and tree characteristics and their interactions is still limited. Here, we investigated canopy temperature regulation for five mature co-occurring tree species for two...

Abundances and indices for soil microbial biomarkers (brGDGTs and isoGDGTs) in eleven soil profiles along a Serengeti transect

Mark D Peaple, Sarah J Feakins, Jessica E Tierney, Naomi E Levin, Christoph Häggi, Emily J Beverly, Samantha Baker & Brittany Garza
Soil profiles were collected along a transect across the Serengeti ecosystem, in Tanzania from 2-3S and 34-35.5E, 1153 to 1677 m above sea level and 0 to 1.6 m soil depth. The samples are modern soils and the temporal span of the soil depth profiles is unconstrained, likely centuries to millennia. The survey is intended to observe soil microbial lipid biomarkers that are commonly used as proxies for temperature and pH and to assess their...

Maria Hörhold, Melanie Behrens, Sonja Wahl, Anne-Katrine Faber, Alexandra Zuhr, Hannah Meyer & Hans Christian Steen-Larsen
Snow samples were taken on a daily basis along a 100 m wind-parallel transect at the EastGRIP ice core deep drilling site. The snow was collected in the morning at 11 positions with 10 m spacing into four cumulative samples – each for one depth interval. The depth intervals are top 0.5 cm , top 1 cm , top 2 cm and top 5 cm . Each day, undisturbed snow was sampled and the exact...
