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...

Data for Effect of Mesoscale Oceanic Eddies on Extratropical Cyclogenesis: a Tracking Approach, supplement to: Zhang, Xingzhi; Ma, Xiaohui; Wu, Lixin (2019): Effect of Mesoscale Oceanic Eddies on Extratropical Cyclogenesis: a Tracking Approach. Journal of Geophysical Research: Atmospheres, 124(12), 6411-6422

Xingzhi Zhang
Oceanic eddies populated in the western boundary current regions in the midlatitude, have been found to exert significant influence on atmospheric boundary layer, storm tracks as well as largescale atmospheric circulation. However, mechanisms governing how mesoscale sea surface temperature (SST) anomalies associated with oceanic eddies affect extratropical cyclogenesis remains unclear. Here, we investigate the influence of Kuroshio oceanic eddies on cyclogenesis in the North Pacific in high resolution climate model simulations using a cyclone tracking...

ArcCRUST: Arctic crustal thickness from 3D gravity inversion, links to files in NetCDF format, supplement to: Lebedeva-Ivanova, Nina; Gaina, Carmen; Minakov, Alexander; Kashubin, Sergei (2019): ArcCRUST: Arctic Crustal Thickness From 3‐D Gravity Inversion. Geochemistry, Geophysics, Geosystems, 20(7), 3225-3247

Nina Lebedeva-Ivanova, Carmen Gaina, Alexander Minakov & Sergei Kashubin
The ArcCRUST model consists of crustal thickness and estimated crustal thinning factors grids for the High Arctic and Circum-Arctic regions (north of 67°N). This model is derived by using 3D forward and inverse gravity modelling. Updated sedimentary thickness grid, an oceanic lithosphere age model together with inferred microcontinent rifting ages, variable crystalline crust and sediment densities, and dynamic topography models constrain this inversion. We use published high-quality 2D seismic crustal-scale models to create a database...

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...

Increased extreme precipitation in Chinese deserts from 1960 to 2018, supplement to: Li, Guoshuai; Yang, Hong; Zhang, Ying; Huang, Chunlin; Pan, Xiaoduo; Ma, Mingguo; Song, Minhong; Zhao, Q H (2019): More Extreme Precipitation in Chinese Deserts From 1960 to 2018. Earth and Space Science (ESS), 6(7), 1196-1204

Guoshuai Li, Hong Yang, Ying Zhang, Chunlin Huang, Xiaoduo Pan, Mingguo Ma, Minhong Song & Q H Zhao
Extreme precipitation over drylands, especially deserts, has been often observed. The precipitation changes in Chinese deserts have been rarely studied. Here, we use a daily grid precipitation dataset generated via weather station data (0.25° horizontal grid spacing) to investigate the spatial and temporal changes in extreme precipitation in Chinese deserts. The extreme precipitation based on the changes in the total precipitation (PRCPTOT) and the annual-maximum daily precipitation (Rx1day) in the Chinese desert exhibits markedly increasing...

Metabolite profiles of two Antarctic sister species (Notothenia rossii and Notothenia coriiceps) at different temperatures, supplement to: Rebelein, Anja; Pörtner, Hans-Otto; Bock, Christian (2018): Untargeted metabolic profiling reveals distinct patterns of thermal sensitivity in two related notothenioids. Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 217, 43-54

Anja Rebelein & Christian Bock
Antarctic marine ectothermal animals may be affected more than temperate species by rising ocean water temperatures due to ongoing climate change. Their specialisation on stable cold temperatures make them vulnerable to even small degrees of warming. Thus, addressing the impacts of warming on Antarctic organisms and identifying their potentially limited capacities to respond is of particular interest.The objective of the study was to determine changes in metabolite profiles related to temperature exposure and acclimation. In...

Microwave-induced self-organization in mineral systems. II. Prussian blue (conentrated sol; 2.45 GHz; 450 W; 2 min). Erosion and reticulation

Oleg V Gradov & Margaret A Gradova
In this dataset cycle we consider a multifactor nature of the self-organization procees of soft matter dissipative microstructures from the iron-containing colloidal precursors with different particle size under microwave irradiation. The resulting structures' morphology determined by the dehydration-aggregation procees under the microwave field, as well as their phase state, chemical composition and the degree of crystallinity, are shown to be dependent on the irradiation time, the microwave field power and the particle size of the...

Tropical cyclone cold wake size dataset, supplement to: Zhang, Jishi; Lin, Yanluan; Chavas, Daniel R; Mei, Wei (2019): Tropical cyclone cold wake size and its applications to power dissipation and ocean heat uptake estimates. Geophysical Research Letters, 46(16), 10177-10185

Jishi Zhang & Yanluan Lin
1. Mixing of the upper ocean by the wind field associated with tropical cyclones (TCs) creates observable cold wakes in sea surface temperature and may potentially influence ocean heat uptake. We derive a novel oceanic metric of tropical cyclone size based on its induced cold wake using sea surface temperature data for a period from 2002 to 2011.2. The cold wake size dataset is based on the daily NOAA 1/4° Optimum Interpolation Sea Surface Temperature,...
