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...

Distribution of mangroves in the Galapagos islands, GIS and Google Earth layers, supplement to: Moity, Nicolas; Delgado, Byron; Salinas-de-León, Pelayo (2019): Mangroves in the Galapagos islands: Distribution and dynamics. PLoS ONE, 14(1), e0209313

Nicolas Moity & Byron Delgado
We provide here the most accurate cover for mangrove forests in the Galapagos Islands. We mapped mangroves using freely available Google Earth Very High Resolution images based on on-screen classification. The mangrove cover corresponds to 2014 since the images we used were mostly from this year. We obtained an area of 3657.1 ha of fringing mangrove that covers 35% of the coastline. Eighty percent of mangrove cover is found in Isabela island, and 90% in...

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,...

Aerial images of eroding permafrost coastline, Qikiqtaruk - Hershel Island, Yukon, Canada, supplement to: Cunliffe, Andrew M; Tanski, George; Radosavljevic, Boris; Palmer, William; Sachs, Torsten; Lantuit, Hugues; Kerby, Jeffrey T; Myers-Smith, Isla H (2019): Rapid retreat of permafrost coastline observed with aerial drone photogrammetry. The Cryosphere, 13(5), 1513-1528

Andrew M Cunliffe, George Tanski, Boris Radosavljevic, William Palmer, Torsten Sachs, Jeffrey T Kerby & Isla H Myers-Smith
Permafrost landscapes are changing around the Arctic in response to climate warming, with coastal erosion being one of the most prominent and hazardous features. Using drone platforms, satellite images, and historic aerial photographs, we observed the rapid retreat of a permafrost coastline on Qikiqtaruk – Herschel Island, Yukon Territory, in the Canadian Beaufort Sea. This coastline is adjacent to a gravel spit accommodating several culturally significant sites and is the logistical base for the Qikiqtaruk...

Microwave-induced self-organization in mineral systems. I. Prussian blue (2.45 GHz; 450 W; 3 min)

In this dataset cycle we consider a multifactor nature of the self-organization processes 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 processes under the microwave field, as well as their phase state, microchemical composition and the degree of crystallinity, are shown to be dependent on the irradiation time, the microwave field power and the particle size and the...

3D Lava flow mapping at Etna volcano from Pléiades-derived DEM differences, supplement to: Ganci, Gaetana; Cappello, Annalisa; Bilotta, Giuseppe; Hérault, Alexis; Zago, Vito; Del Negro, Ciro (2019): 3D Lava flow mapping of the 17-25 May 2016 Etna eruption using tri-stereo optical satellite data. Annals of Geophysics, 62(2), 1-6

Gaetana Ganci, Annalisa Cappello, Giuseppe Bilotta, Alexis Hérault, Vito Zago & Ciro Del Negro
We present two 2-meter Digital Elevation Models (DEMs) of Mount Etna obtained from tri-stereo Pléiades images acquired on 24 December 2015 and 18 July 2016. The 3D processing of the Pléiades imagery was performed using the free and open source MicMac photogrammetric library (http://micmac.ensg.eu) developed by the French IGN (Institut Géographique National).The covered area is almost the same for both the DEMs (about 15 × 15 km) and includes the summit area of Etna volcano...

TLS snow distribution maps of the Weisssee snow research site (Kaunertal, Austria), supplement to: Fey, Christine; Schattan, Paul; Helfricht, Kay; Schöber, Johannes (2019): A compilation of multitemporal TLS snow depth distribution maps at the Weisssee snow research site (Kaunertal, Austria). Water Resources Research, 55(6), 5154-5164

Christine Fey, Paul Schattan, Kay Helfricht & Johannes Schöber
The data set comprises the inter- and intra-annual snow depth distribution recorded by TLS scans at Weisssee snow research site in Austria between November 2014 and May 2018. The data set comprises 23 snow-on digital elevation models (DEM), one snow-off DEM, and the difference raster calculated between a snow-off and snow-on scans.The relative accuracy of the TLS scans was determined by measuring the distance between snow-free planes from the snow-on and snow-off scans and shows...

Number of microplastic particles on periwinkle pedal mucus in experimental setups, supplement to: Gutow, Lars; Bartl, Kevin; Saborowski, Reinhard; Beermann, Jan (2019): Gastropod pedal mucus retains microplastics and promotes the uptake of particles by marine periwinkles. Environmental Pollution, 246, 688-696

Lars Gutow, Kevin Bartl, Reinhard Saborowski & Jan Beermann
The rapid dissemination of microplastics in many habitats of the oceans has raised concerns about the consequences for marine biota and ecosystems. Many adverse effects of microplastics on marine invertebrates are consequences of ingestion. Accordingly, the identification of mechanisms that facilitate the uptake of microplastics is essential for the evaluation of possible implications for marine organisms and food webs. Gastropods produce mucus for locomotion. Gastropod pedal mucus naturally retains formerly suspended micro-organisms, such as bacteria,...

The Cryosphere, 12(12), 3853-3859

Sue Cook, Ben Galton-Fenzi, Stefan R M Ligtenberg & Karen Helen Wiltshire
The firn densification model IMAU-FDM has been used to simulate the firn density profile around Antarctica. The model is forced at the surface with climate data from the RACMO2.3 regional climate model. Here we provide the depth of three key firn density layers below the surface (750, 800 and 830 kgm^-3), averaged over the period 1979-2013. The data is on a horizontal grid of 27x27 km. The depth of each of these density layers was...
