    Description: In laboratory experiments on field-collected animals (June-August 2021), we investigated the influence of three realistic artificial light at night (ALAN) regimes on food consumption rates and feeding rhythmicity in the sea urchins Arbacia lixula and Paracentrotus lividus and the snail Cerithium spp. from the Adriatic Sea (Pula, Croatia). Food consumption was assessed in assays with algal pellets, while feeding rhythms were documented with 24 h time-lapse photography. Both was done in animals that had been acclimated to ALAN for two weeks and in non-acclimated animals. We observed short-term and potential long-term alterations in the feeding rhythms of Cerithium spp. and Paracentrotus lividus, respectively, but found no lasting effects on consumption rates. Effects were less pronounced when ALAN was applied only part-night. Data contains (1) information about place and time of the animal collection, (2) details about the laboratory experiments, (3) measured food consumption rates under ALAN, (4) day-/night feeding behaviour under ALAN derived from time-lapse photography, and (5) consumption rates under red light. Data for all three species is provided.

    Trace element and stable isotope data of subaqueous grown speleothems (Hells Bells) from the northeastern Yucatán Peninsula (2022)
    PANGAEA
    Details
    Publication Date: 2023-08-22
    Description: This dataset provides geochemical data (trace elements and stable isotopes) of subaqueous grown speleothems (Hells Bells) from the north-eastern Yucatán Peninsula. These secondary carbonates were collected from three different sinkholes (cenotes) southwest of Cancún, Quintana Roo, Mexico (20.51–20.52°N, 87.01–87.07°W) at water depths between -29.4 m a.s.l and -37.3 m a.s.l. Samples were collected in situ and their elevation was measured with a dive computer (+-0.1m). For samples taken from the bottom of the cenotes, we cannot assign a corresponding water depth since we have no information about their original position on the cave ceiling. Major and trace elements were determined by ICP-OES. Stable carbon and oxygen isotope measurements were carried out by a ThermoFinnigan MAT253Plus gas source mass spectrometer equipped with a Thermo Fisher Scientific Kiel IV carbonate device.

    Description: This dataset contains 80 U-Th ages of subaqueous grown speleothems (Hells Bells) from the north-eastern Yucatán Peninsula.

Samples were collected in situ and their elevation was measured with a dive computer (+-0.1m). For samples taken from the bottom of the cenotes, we cannot assign a corresponding water depth since we have no information about their original position on the cave ceiling. The measurements were carried out by a multi-collector inductively coupled plasma mass spectrometer (ThermoFisher Neptune Plus).

    Description: The magnetotelluric impedance tensor elements and errors were calculated with the software BIRRP (Chave &Thomson, 2004; doi:10.1111/j.1365-246X.2004.02203.x). Magnetotelluric measurements were conducted from December 2010 to January 2011 at the Walvis Ridge, offshore Namibia. Coordinates of the MT stations are included in the EDI files and cover an area at ~8°E - 12°E, ~18°S-22°S. Station deployment and recovery was conducted on the two cruises MSM17/1 and MSM17/2 on German research vessel Maria S. Merian as part of the SPP1375 priority program SAMPLE. The SAMPLE project focused on the processes linked to continental margin formation.

    Star Photometer Data (AOD) 2010 - 2021 from Ny-Ålesund, Svalbard (AWIPEV) (2021)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The star photometer at AWIPEV is a permanent installation and fills the measurement gap of the sun photometer during polar night by using the brightness of defined stars. The instrument data is only available in clear sky conditions. In this regard the data should represent the real aerosol conditions. Only aerosols that are advected and processed within clouds or hygroscopic growth cannot be measured by this instrument. To minimize measuring errors bright and, as a local advantage, circumpolar stars are chosen for photometry. The three stars gamma Gem, beta UMa and alpha Lyr are used for both types of measurement. The star alpha Aql has only been used for two star measurement yet. The measuring principle of a star photometer is the same as for the sun. There are two different possibilities to determine the AOD (aerosol optical depth) using a star photometer. One star measurement requires a calibration at very clear nights, just like Langley calibration for sun photometers. For the two star measurement a calibration is not needed in advance. But on the other hand the second method is much more effective by atmospheric inhomogeneities and horizontally stratified layers. In this data set AOD, Angstrom-Exponent and modified Angstrom-Exponent (Graßl, Ritter 2019, Remote Sensing, https://doi.org/10.3390/rs11111362) are given for the star photometer at AWIPEV for the time 10 Nov. 2010 to 21. Feb 2021. The variables are in netcdf format for each measurement day. The used instrument for the entire measurment period was star04.
