Chironomidae subfossil record from a sediment core of the Anthropocene reveals potential as a paleoclimatic proxy at a Brazilian Tropical Coast site
No full textThis dataset presents sedimentological, geochemical, and subfossil Chironomidae data from a mangrove core collected at Ilha Grande, Rio de Janeiro State, southeastern Brazil (approx. 23°S, 44°W). The record includes head capsule counts of Chironomidae separated into three size fractions (>250 µm, 250–88 µm, and 88–74 µm), along with sediment density, chronological information, and concentrations of major and trace elements (e.g., Al, Fe, Mn, Pb, Zn, Ti, Si, P, S, and others). Linear and power-based air temperature reconstructions (°C) were derived from Chironomidae assemblages using transfer functions developed for tropical regions. The core was sampled in 2023 and dated using combined ²¹⁰Pb analyses with CRS model, covering approximately the last 170 years (1860–2024 CE). Sediment slices of 1 cm were analyzed for biological and geochemical parameters to assess recent environmental and climatic variability in tropical coastal ecosystems. Chironomidae head capsules were extracted using standard subfossil preparation protocols, mounted under optical microscopy, and identified to morphotype level following Walker (2001) and Brooks et al. (2007) with aditional personal modifications. Elemental concentrations were determined via X-ray fluorescence (XRF) spectroscopy, and total density was measured gravimetrically
Master track of ELISABETH MANN BORGESE cruise EMB343 in 1 sec resolution (zipped, 40 MB)
No full textRaw data acquired by position sensors on board RV Elisabeth Mann Borgese during expedition EMB343 were processed to receive a validated master track which can be used as reference of further expedition data. During EMB343 data from the motion reference unit exail Phins Gen.3, the Trimble SPS356 GPS receiver, the Furuno GP-170 and the Furuno GP-150 GPS receiver were used to calculate the mastertrack. 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
Master track of Eugen Seibold cruise ES22C05, Playa Blanca - Playa Blanca, 2022-03-10 - 2022-03-11
No full textThis dataset contains the validated master track of the S/Y Eugen Seibold during expedition ES22C05, with a time resolution of about 10 seconds. This master track can be used as reference for further expedition data. For creating the master track, the 1-second resolution raw data acquired by the GPS position sensor on board S/Y Eugen Seibold were processed, averaging latitude and longitude within equidistant 10-second intervals. Quality control was performed visually and by checking the maximum speed calculated between neighbouring positions. In case of unrealistically high speeds, data points have been removed

Windcube V2 measurements during Meteor cruise M207
No full textThe WindCube 2.0 vertical profiling lidar was placed on the ship to measure horizontal wind speed and direction profiles from 40m to about 300m. This pulsed Doppler lidar was continually measuring in DBS (Doppler-Beam-Swinging) mode, where 4 lines of sight measured each cardinal direction at a 28° angle to obtain the horizontal wind components, and a 5th line of sight measuring the vertical wind speed. The recordings of the lidar device are combined with those of a motion measurement setup, comprising an Inertial Measurement Unit (IMU) and a satellite compass that provide motion data in all six degrees of freedom. Motion data are applied to obtain the corrected wind profile data both on a 1-sec and 10-min level.
For the first part of the campaign, until early February 2024, the lidar was set up to measure at 12 levels up to 200m height. After that the maximum measurement height was adjusted to 290m.
The reported Carrier-to-Noise (CNR) level is used to control the quality the measurement, typically leading to a lower data availability at the top heights
Concentrations of planktic foraminifera and percentages of species from sediment core AMK-6150 (Norwegian Sea)
No full textThe dataset contains micropaleontological data from core AMK-6150 (Norwegian Sea) that covers the last 2900 years. The data include concentrations of planktic foraminifera and percentages of species from core AMK-6150 in relation with core depth and age
Continuous salinity observations at station BEFmate_I3pio, 2017-04 to 2017-12
No full textData presented here were collected between April 2017 to December 2017 in the BEFmate project (Biodiversity - Ecosystem Functioning across marine and terrestrial ecosystems) of the Universities of Oldenburg and Göttingen and the Nationalparkverwaltung Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were established in the back-barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog (Germany). Salinity at different elevation zones was measured using conductivity loggers deployed in dip wells within experimental islands as well as in the saltmarsh enclosed plots. Measurements were obtained using HOBO U24 Conductivity Logger U24-002-C (Onset Computer Corporation, Bourne, MA/USA). All devices were pre-calibrated by the manufacturer. Logged data were retrieved in the field using a Hobo Underwater Shuttle (U-DTW-1) and were read out with the HOBOware Pro (V3.7.28) software. Salinity was derived in HOBOware Pro using temperature-dependent, nonlinear seawater conductivity compensation following the Practical Salinity Scale (PSS-78). Subsequent data processing was done using MATLAB (R2024b). Post-processing and quality control included (a) the removal of data covering maintenance activities, (b) the removal of implausible values using fixe thresholds (salinity > 40 psu and 35 °C and < -5 °C), c) an outlier detection using the Hampel filter method, and (d) visual checks. Identified outliers were removed and synchronously removed across all associated parameters (temperature and salinity)
