Benthic stable carbon and oxygen isotopes of Cibicidoides wuellerstorfi from ODP Hole 130-806B 0-4 m.y
ODP Leg 130 - Site 806B benthic stable carbon and oxygen isotopes have been measured using the epibenthic foraminifer species Cibicidoides wuellerstorfi in cores cores 1H to 11H of Hole B, only. Stratigraphy is based on correlation to the benthic oxygen isotope stack of Lisiecki and Raymo 2005 (Paleoceanography vol 20, PA1003, doi:10.1029/2004PA001071)
Calibration function of 141 surface sediment samples from the South Atlantic and the Atlantik sectorof the Southern Ocean
We provide a new multivariate calibration-function based on South Atlantic modern assemblages of planktonic foraminifera and atlas water column parameters from the Antarctic Circumpolar Current to the Subtropical Gyre and tropical warm waters (i.e., 60°S to 0°S). Therefore, we used a dataset with the abundance pattern of 35 taxonomic groups of planktonic foraminifera in 141 surface sediment samples. Five factors were taken into consideration for the analysis, which account for 93% of the total variance of the original data representing the regional main oceanographic fronts. The new calibration-function F141-35-5 enables the reconstruction of Late Quaternary summer and winter sea-surface temperatures with a statistical error of ~ 0.5°C. Our function was verified by its application to a sediment core extracted from the western South Atlantic. The downcore reconstruction shows negative anomalies in sea-surface temperatures during the early–mid Holocene and temperatures within the range of modern values during the late Holocene. This pattern is consistent with available reconstructions.Fil: García Chapori, Natalia Luz. Consejo Nacional de Investigaciones Científicas y Técnicas.

Master track of MARIA S. MERIAN cruise MSM127 in 1 sec resolution (zipped, 122 MB)
Raw data acquired by position sensors on board RV MERIAN during expedition MSM127 were processed to receive a validated master track which can be used as reference of further expedition data. During MSM127 the motion reference unit Kongsberg SeaTex AS MRU-5 combined with Kongsberg SeaTex AS Seapath 320 and the GPS receivers Trimble SPS855 and SAAB R4 were used as navigation sensors. Data were downloaded from DAVIS SHIP data base (https://dship.bsh.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track
Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV MARIA S. MERIAN during cruise MSM127
Raw multibeam bathymetry data were collected aboard RV MARIA S. MERIAN during cruise MSM127 MAURIBO using a Kongsberg 12kHz EM 122 multibeam echosounder. The expedition took place during 18.03.2024- 20.04.2024 from Las Palmas to Las Palmas (Gran Canaria) in the Northern Atlantic. Data were recorded in the EEZs of Mauritania and Western Sahara and outside. The main objective of the MSM127 (Bremen Cluster expedition MAURIBO) research expedition was aimed at obtaining long sedimentary records by using the Bremen sea floor drill rig MeBo70. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Data acquisition was done by MARUM, provision of the data is supported by the DAM Underway Project and published according to the FAIR principles
