We conducted four surveys, and resultant data is recorded on four separate sheets within the document, titled S1, S2, S3, and NAS. The S1-S3 data pertain to surveys of astrobiologists on the existence of basic/complex/intelligent extraterrestrial life. The NAS data pertain to a survey of non-astrobiologist scientists, on the existence of any kind of extraterrestrial life.

The DAISIE - inventory of alien invasive species in Europe is a species checklist dataset published by the Research Institute for Nature and Forest (INBO) and the Centre for Ecology and Hydrology (CEH). It contains information on 12,104 taxa (mostly species and mostly introduced) occurring in the wild in Europe since 1500. It covers a broad taxonomic spectrum of terrestrial and aquatic free living and parasitic organisms. The collation of the alien species list is the result of the efforts of the DAISIE (http://www.europe-aliens.org/) project partners and more than 300 collaborators from Europe and neighbouring countries, involved in different fields of expertise and organisations. Here the DAISIE checklist is published as a standardized Darwin Core Archive and includes for each species: the scientific name, higher classification, and stable taxon identifier (in the taxon core), the vernacular names (in the vernacular names extension), the presence in a specific region, the year of the first introduction (first collection) and/or last assessment/observation in that region, as well as extra information (in the distribution extension), and the habitat, native range, and ecofunctional group (in the description extension). The DAISIE dataset is no longer maintained, but can be used as a historical archive for researching and managing alien plants or compiling regional and national registries of alien species. Issues with the dataset can be reported at https://github.com/trias-project/daisie-checklist

When germinated and grown on-board the ISS (International Space Station) plant do not exhibit abnormal structures but they do have altered growth habits and this project aims to investigate the molecular mechanisms that provide the foundation for the altered growth habits observed in orbit. APEX03-2 (Advanced Plant Experiment 03-2) also known as TAGES-ISA (Transgenic Arabidopsis Gene Expression System-Intracellular Signaling Architecture) specifically addresses the growth and molecular changes that occur in Arabidopsis thaliana plants during spaceflight by using molecular and genetic tools and by asking fundamental questions regarding root structure growth and cell wall remodeling may be answered. This investigation advances the fundamental understanding of the molecular biological responses to extraterrestrial environments. This understanding helps to further define the impacts of spaceflight on biological systems to better enable NASA x92s future space exploration goals.

The abundances of Platinum Group Elements (PGEs: Ruthenium, Rhodium, Palladium, Osmium, Iridium, and Platinum) are high in meteorites and extremely low in terrestrial rocks and water and accumulations of mainly platinum and iridium in ancient polar archives have been argued to trace terrestrial (continental/volcanic dust) and extra-terrestrial sources. The PGE concentration data, however, lack specificity. For example, the extent to which terrestrial dust compared to cosmic dust has contributed to the PGE inventory of polar ice cannot be readily evaluated from the PGE concentration data alone. Since the osmium isotopic compositions (R(187Os/188Os) ratio) of terrestrial (= 1.40 ± 0.30) and extraterrestrial/volcanic sources (= 0.13) are distinctly different from each other, osmium isotopic composition has the potential to elucidate relative contributions from these sources in ancient polar ice. However, the determination of osmium isotopes in polar ice core archives is challenging due to extremely low concentrations (∼10E-15 g g−1), and due to the availability of small sample sizes (tens of grams). The main objective of this study is to develop a highly sensitive procedure that allows accurate and precise determination of osmium concentration and isotope composition using ~50 g of melted Greenland ice or snow. By substantially improving previously established clean lab chemistry and high sensitivity mass spectrometry we analyzed snow collected from Summit, Greenland during 2009, 2014, and 2017. We find that the average osmium concentration of the snow is 0.459 ± 0.018 (95% C.I.) fg g−1 corresponding to an osmium flux of 0.0579 ± 0.0023 (95% C.I.) fmol cm−2 yr−1. The average R(187Os/188Os) ratio of the Summit snow is 0.264 ± 0.026 (95% C.I.). Assuming that the volcanic source is negligible, the average ratio indicates that about 0.0518 ± 0.0040 (95% C.I.) fmol cm−2 yr−1 of osmium is of cosmic derivation, corresponding to an accretion rate of extra-terrestrial osmium to the Earth of 264 ± 21 mol yr−1. This assessment is similar to the present-day accretion rate of extra-terrestrial osmium to the Earth determined by previous studies. Because of its sensitivity our procedure can be extended to study changes in the accretion of extra-terrestrial osmium over the last several hundred thousand years using samples of ice core. The data contains osmium concentration and isotope composition of (1) reagents and procedural blanks of two Osmium purification methods (Table 1), (2) Antarctic sea snow, sea water, and NEEM firn for method comparison (Table 2), and finally (3) modern snow from Summit, Greenland for sample application (Table 3).

The aim of this proposal is to investigate the application of highly-curved HAPG analyzer crystals in WD-XRF spectroscopy for the simultaneous analysis of lanthanides in unique extraterrestrial materials and explore its 3D voxel scanning capabilities at low excitation energies. For this a novel analysis technique is proposed to obtain non-destructive, selective volume information of rare earth elements (REEs) in µm-sized analogues of coarse grain asteroid samples in preparation for the initial analysis of materials from asteroid sample return missions. The combination of cylindrical HAPG optics with ultra-high curvature having a mm-sized working distance is expected to provide higher throughput and collimation as compared to high energy resolution fluorescence detection (HERFD) spectroscopy.

The Manual of the Alien Plants of Belgium is a species checklist dataset published by the Botanic Garden Meise. It contains information on all (over 2.500) non-native vascular plants occurring in the wild in Belgium since 1800. The checklist is almost entirely based on a thorough herbarium revision of the main public Belgian herbaria (Verloove 2006), actively maintained, and updated regularly at Verloove (2018, http://alienplantsbelgium.be). Here it is published as a standardized Darwin Core Archive and includes for each species: the scientific name, kingdom, family, stable taxon identifier, and IPNI (2018) scientific name ID where available (in the taxon core), the presence in Flanders, Wallonia and the Brussels Capital Region, as well as the year of the first introduction (first collection) and last assessment/observation in Belgium (given as a year range in the event date in the distribution extension), coarse habitat information (in the species profile extension), and the pathway(s) of introduction, native range(s) and invasion stage in Belgium (in the description extension). The dataset can be used for researching and managing alien plants or compiling regional and national registries of alien species. Issues with the dataset can be reported at https://github.com/trias-project/alien-plants-belgium

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Invasive alien species in Canada main indicator is the number of invasive alien species found to be newly established in Canada, reported by year and regulatory status. This provides a preliminary indication of the potential harmful consequences of new arrivals. A secondary indicator, the proportion of regulated species that have not established in Canada, is reported as a partial measure of regulatory success. Regulation of potentially invasive species is intended to prevent their introduction and establishment in Canada. Species are added to the list of regulated species based on an analysis of risk. Both indicators report on species establishment since January 2012. With the implementation of the Federal Sustainable Development Strategy 2010–2013, this type of information began to be collected consistently across multiple programs, allowing information to be combined for the first time into a single indicator despite the varying approaches used to control different groups of invasive alien species. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for data sources and details on how those data were collected and how the indicator was calculated.
