title: Meteorological measurements in 2021, close to Lake Elmo

description: Continuous observations were made of weather conditions at the pond, including temperature, wind velocity, wind direction, solar radiation, humidity, and rainfall. The observations were made from February 3rd, 2021 to March 21th 2021, The pond used for these observations is situated in Lake Elmo, Minnesota, USA, the pond center located at 45.0220, -92.8916. An Ambient Weather Model WS-2902C observing station was situated on the North-East side of the pond, about 2 m from the nominal shoreline. The data was collected to experimentally determine effects of surface albedo modification on ice melt and thermodynamic processes of a freshwater pond. In this experiment we applied a coating of reflective hollow glass microspheres to a test section, while leaving a control section unmodified. The data was used to develop a thermodynamic model of the pond using weather conditions to model heat flows and to confirm snowfall events. The Ambient Weather observing station transmits its readings via WiFi to a WS-2902C receiver which is connected wirelessly to the Internet, and the readings are stored for one year. These data points were downloaded and processed.

title: Laboratory particle size measurements of hollow glass microsphere products 'Potters 25P45' and '3M K1'

description: We commissioned laboratory evaluations of several available hollow glass microsphere products. Particle Technology Laboratories made particle size measurements for 3M™ K1 and Potters Sphericel™ 25P45 hollow glass microspheres (HGMs). The measurements were made in August 2020 at PTL's laboratory in Downers Grove, IL. The purpose of the measurements was to evaluate widely available hollow glass microsphere materials obtainable from multiple sources for effectiveness in reducing ice melt. A further purpose was to select materials for evaluation in field experiments and to compare size distributions. A further purpose was to determine the percentage of particles below 10 microns for evaluation for safety. A further purpose was to compare particle size measurements with reflectivity measurements.The measurements were made by laser diffraction using a Malvern Mastersizer 3000 (Particle Technology Laboratories, Downers Grove, IL). Particles were delivered with dry sample introduction due to the buoyancy of the particles in typical solvents used for particle size measurement. The lowest venturi setting was used to avoid damage and breakage to the microspheres during sample measurement. Optical microscopy of the samples after particle size measurement confirmed the integrity of the particles through the laser diffraction measurement.

title: Metabolite profiles of two Antarctic sister species (Notothenia rossii and Notothenia coriiceps) at different temperatures

description: 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 a long-term experiment adult fish of two Antarctic sister species Notothenia rossii and Notothenia coriiceps were acclimated to 0 °C and 5 °C for three months. Impacts and indicators of acclimation at the cellular level were determined from metabolite profiles quantified in gill tissue extracts by using nuclear magnetic resonance (NMR) spectroscopy. Furthermore, the metabolite profiles of the two con-generic species were compared.NMR spectroscopy identified over 40 metabolites that were present in each sample, but varied in their absolute concentration between species and between treatments. Variations in the concentration of phospholipid compounds, amino acids and osmolytes suggested that warming caused changes in the cellular membrane structure. It also increased the catabolism of amino acids and initiated shifts in osmoregulation. Some differences in the metabolite profile between the two notothenioid species were related to their divergent lifestyles, especially their different rates of motor activity. Increased levels of the Krebs cycle intermediate succinate and falling amino acid levels in warm-acclimated N. rossii suggested that N. rossii is more sensitive to warming than N. coriiceps.Data are obtained from dried polar gill extracts, which were re-suspended in deuterated water (D2O) to a final concentration of 1 g frozen gill tissue/ml solvent. The D2O contained 0.05 wt.% of 3-(trimethylsilyl) propionic-2,2,3,3-d4 acid, sodium salt (TSP) (Sigma Aldrich, St. Louis, USA). TSP was used as chemical shift and quantification standard. For each sample 50 µl of the resuspended gill extracts were analysed.

title: Distribution of mangroves in the Galapagos islands, GIS and Google Earth layers

description: 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 the western and central south-eastern bioregions. The overall accuracy of mangrove classification was 99.1% with a Kappa coefficient of 0.97 when validated with field data. The mapped mangrove forests are composed by three species of mangroves, Rhizophora mangle (red mangrove, Fam. Rhizophoraceae), Avicennia germinans (black mangrove, Fam. Acanthaceae) and Laguncularia racemosa (white mangrove, Fam. Combretaceae); and occasionally Conocarpus erectus (button or buttonwood mangrove, Fam. Combretaceae) although we do not differentiate species in our layer, we map the mangrove assemblage. The GIS layer has a relative scale of 1:2500± 125. This publication is contribution number 2235DS of the Charles Darwin Foundation for the Galapagos Islands.
description: The aim of this shapefile is to provide the most accurate cover for mangrove forests in the Galapagos Islands. This dataset ensures that the layer is readily available to support institutions responsible for the management and conservation of the natural resources of the Galapagos islands and for the use of any researcher interested in this type of information. All updates of this layer will be available through this media.

title: Heavy mineral study of the glacigenic deposits from the East Siberian continental margin collected during the SWERUS-C3 expedition

description: The heavy mineral signature of glacigenic deposits from the East Siberian continental margin were studied and the data presented are from samples from cores acquired on Leg 2 of the SWERUS-C3 2014 Expedition on IB Oden, which departed 21 August from Barrow, Alaska, and ended 3 October in Tromsø, Norway. Four sediment cores presented were collected using either a piston (PC) or gravity (GC) corer, both rigged with a 1360 kg core head. The unsplit sediment cores logged shipboard on a Multi-Sensor Core Logger (MSCL). A total of 17 samples were analysed. Two samples are from the 0.83 m long core 20-GC1, which was recovered in 115 m water depth from the East Siberian shelf. Two diamict samples are from the 4.06 m long core 23-GC1, which was recovered in water depth of 508 m, and nine samples are from 4.05 m long core 24-GC1 recovered in water depth of 964 m from the De Long Trough. The samples from core 24-GC1 also include surface sediments and other lithologies found between the seafloor and the diamict. Four samples are from core 29-GC1. The 4.66 m long core was recovered in 824 m water depth from the southern Lomonosov Ridge. The heavy mineral grains &gt;63 μm from 17 samples were analysed with Zeiss Ultra Plus Scanning Electron Microscope (SEM) at the Centre for Material Analysis, University of Oulu in 2019. Heavy mineral identification was done by using MinIdent-Win 3.0 computer program. The 18 analysed elements Na, Mg, Al, Si, P, S, K, Ca, Ti, V, Cr, Fe, Cu, Zn, Zr, La, Ce, and Nd (expressed as oxides) were used in the specification of the minerals.

title: Morphological determination of the phototrophic community composition of biological soil crusts in coastal sand dunes in northern Germany

description: This dataset comprises the microbial community composition of biological soil crusts in north-German sand dunes. For this we obtained enrichment cultures of phototrophic microorganisms, by placing fragments of biocrusts of the same Petri dishes as used for sequencing, in Petri dishes with Bold Basal (1N BBM) agarized medium (Bischoff and Bold 1963). Cultures were grown under standard laboratory conditions: with a 12-hour alteration of light and dark phases and irradiation of 25 μmol photons m-2 s-1 at a temperature 20 ± 5 ºС. Microscopic study of these raw cultures began in the third week of cultivation. Morphological examinations were performed using Olympus BX53 light microscope with Nomarski DIC optics (Olympus Ltd, Hamburg, Germany). Micrographs were taken with a digital camera (Olympus LC30) attached to the microscope, and processed by the Olympus software cellSens Entry. Direct microscopy of rewetted samples was performed in parallel with cultivation for evaluation of dominating species of algae and cyanobacteria in the original samples. Morphological identification of the biocrust organisms was based mainly on Ettl and Gärtner (2014) for green microalgae, and on Komárek (2013) for cyanobacteria, as well as on some monographs and papers devoted to taxonomic revisions of the taxa of interest (Darienko and Pröschold 2019). Moss and lichens samples were air-dried after collection. For determination, a microscope with a maximum magnification of 400x was used. Morphological identification of mosses followed Frahm and Frey (2004) with taxonomical reference to (Hodgetts et al. 2020). Lichens were determined according to Wirth et al. (2013). Morphologically critical species of the genus Cladonia where additionally analyzed by thin-layer chromatography according to (Culberson and Ammann 1979) in solvent system A.
