Climate records from different places in black cherry - pine forests in the Havelland, north-eastern Germany

Jonas Geschke
The data has been gathered in order to investigate the influence of the invasive black cherry (Prunus serotina Ehrh.) on bats (Chiroptera: Verpertilionidae) in Scots pine (Pinus sylvestris) forest ecosystems. The bat calls were recorded using automated recording devices (batcorders) in pine forest stands with three different black cherry densities (pine monoculture, light and dense black cherry) for a period of 60 survey nights between the end of July and late September 2016. Three plots...

A trait collection of marine fish species from North Atlantic and Northeast Pacific continental shelf seas

Esther Beukhof, Tim S Dencker, M L D Palomares & Aurore Maureaud
This dataset containing traits of marine fish is based on fish taxa observed during international scientific bottom-trawl surveys regularly conducted in the Northeast Atlantic, Northwest Atlantic and the Northeast Pacific. These scientific surveys target primarily demersal (bottom-dwelling) fish species, but pelagic species are also regularly recorded. The overarching aim of this dataset was to collect information on ecological traits for as many fish taxa as possible and to find area-specific trait values in order to...

Systemic swings in end-Permian climate from Siberian Traps carbon and sulfur outgassing - link to CESM model output, supplement to: Black, Benjamin A; Neely, Ryan R; Lamarque, Jean-François; Elkins-Tanton, Linda; Kiehl, Jeffrey T; Shields, Christine A; Mills, Michael; Bardeen, Charles (2018): Systemic swings in end-Permian climate from Siberian Traps carbon and sulfur outgassing. Nature Geoscience, 11(12), 949-954

Benjamin A Black, Ryan R Neely, Jean-François Lamarque, Linda Elkins-Tanton, Jeffrey T Kiehl, Christine A Shields, Michael Mills & Charles Bardeen
Siberian Traps flood basalt magmatism coincided with the end-Permian mass extinction approximately 252 million years ago. Proposed links between magmatism and ecological catastrophe include global warming, global cooling, ozone depletion, and changes in ocean chemistry. However, the critical combinations of environmental changes responsible for global mass extinction are undetermined. In particular, the combined and competing climate effects of sulfur and carbon outgassing remain to be quantified. Here we present model outputs from global climate model...

Spectral irradiance above and under sea ice from ROV measurements 2011-2017, supplement to: Katlein, Christian; Arndt, Stefanie; Belter, Hans Jakob; Castellani, Giulia; Nicolaus, Marcel (2019): Seasonal Evolution of Light Transmission Distributions Through Arctic Sea Ice. Journal of Geophysical Research: Oceans, 124(8), 5418-5435

Christian Katlein, Stefanie Arndt, Hans Jakob Belter & Marcel Nicolaus
Measurements of solar radiation over and under sea ice have been performed on various stations in the Arctic Ocean during various Polarstern cruises between 2011 and 2017. All radiation measurements have been performed with Ramses spectral radiometers (Trios, Rastede, Germany). All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). One sensor was mounted on a Remotely Operated Vehicle (ROV)...

List of taxa in the OFOS photographic survey images and in Agassiz trawl samples during POLARSTERN cruise PS80 (ARK-XXVII/3, IceArc)

Elena Rybakova, Antonina Kremenetskaia, Andrey Vedenin, Antje Boetius & Andrey V Gebruk
A photographic survey was carried out during the expedition ARK-XXVII/3 to the Nansen and Amundsen basins. The seafloor was photographed using a towed Ocean Floor Observation System (OFOS). Nine transects were performed: four in the Nansen Basin between 83-84°N and 18-110°E at depths 3571-4066 m, and five in the Amundsen Basin between 83-89°N and 56-131°E at depths 4041-4384 m. All images were analysed and stored using the image analysis program and database BIIGLE (BIIGLE.de). Visible...

Differential impact of anthropogenic pressures on Caspian Sea ecoregions, supplement to: Lattuada, Matteo; Albrecht, Christian; Wilke, Thomas (2019): Differential impact of anthropogenic pressures on Caspian Sea ecoregions. Marine Pollution Bulletin, 142, 274-281

Matteo Lattuada, Christian Albrecht & Thomas Wilke
Over the past decades, overall ecological conditions in the Caspian Sea have deteriorated. However, a comprehensive understanding of lake-wide spatial differences in anthropogenic pressures is lacking and the biological consequences of human impacts are poorly understood. This paper therefore aims at assessing the individual and combined effects of critical anthropogenic pressures on the Caspian Sea ecoregions. First, cumulative pressure scores were calculated with a cumulative environmental assessment (CEA) analysis. Then, the individual contribution of anthropogenic...

Foraminifera optical microscope images with labelled species and segmentation labels

Ritayan Mitra, Thomas M Marchitto, Qian Ge, Boxuan Zhong & Edgar Lobaton
The dataset contains foraminifera images of over 1,000 forams taken under 16 different lighting directions with an optical microscope. The species and locations of the samples are also specified. It also contains manual segmentation of over 400 samples from the images described above. The segmentation labels are matched by their name.To capture these images, a visual identification system was developed in order to automate the identification of target microorganisms. The visual system incorporates a controllable...

Livestock grazing intensity in Kazakhstan from 2015 based on NPP and spatial allocation model, supplement to: Hankerson, Brett R; Schierhorn, Florian; Prishchepov, Alexander V; Dong, Changxing; Eisfelder, Christina; Müller, Daniel (2019): Modeling the spatial distribution of grazing intensity in Kazakhstan. PLoS ONE, 14(1), e0210051

Brett R Hankerson, Florian Schierhorn, Alexander V Prishchepov, Changxing Dong, Christina Eisfelder & Daniel Müller
We developed a spatial model that combines fine-scale livestock numbers with their associated energy requirements to distribute livestock grazing demand onto a map of energy supply, with the aim of estimating where and to what degree pasture is being utilized. We applied our model to Kazakhstan, which contains large grassland areas that historically have been used for extensive livestock production but for which the current extent, and thus the potential for increasing livestock production, is...
