The Gaia-ESO Public Spectroscopic Survey: Motivation, implementation, GIRAFFE data processing, analysis, and final data products

Context. The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100 000 stars, including large representative samples of the stellar populations in the Galaxy, and a well-defined sample of 60 (plus 20 archive) open clusters. We provide internally consistent results calibrated on benchmark stars and star clusters, extending across a very wide range of abundances and ages. This provides a legacy data set of intrinsic value, and equally a large wide-ranging dataset that is of value for the homogenisation of other and future stellar surveys and Gaia's astrophysical parameters. Aims. This article provides an overview of the survey methodology, the scientific aims, and the implementation, including a description of the data processing for the GIRAFFE spectra. A companion paper introduces the survey results. Methods. Gaia-ESO aspires to quantify both random and systematic contributions to measurement uncertainties. Thus, all available spectroscopic analysis techniques are utilised, each spectrum being analysed by up to several different analysis pipelines, with considerable effort being made to homogenise and calibrate the resulting parameters. We describe here the sequence of activities up to delivery of processed data products to the ESO Science Archive Facility for open use. Results. The Gaia-ESO Survey obtained 202 000 spectra of 115 000 stars using 340 allocated VLT nights between December 2011 and January 2018 from GIRAFFE and UVES. Conclusions. The full consistently reduced final data set of spectra was released through the ESO Science Archive Facility in late 2020, with the full astrophysical parameters sets following in 2022. A companion article reviews the survey implementation, scientific highlights, the open cluster survey, and data products

The Gaia-ESO Public Spectroscopic Survey: Implementation, data products, open cluster survey, science, and legacy

Context. In the last 15 years different ground-based spectroscopic surveys have been started (and completed) with the general aim of delivering stellar parameters and elemental abundances for large samples of Galactic stars, complementing Gaia astrometry. Among those surveys, the Gaia-ESO Public Spectroscopic Survey, the only one performed on a 8m class telescope, was designed to target 100 000 stars using FLAMES on the ESO VLT (both Giraffe and UVES spectrographs), covering all the Milky Way populations, with a special focus on open star clusters. Aims. This article provides an overview of the survey implementation (observations, data quality, analysis and its success, data products, and releases), of the open cluster survey, of the science results and potential, and of the survey legacy. A companion article reviews the overall survey motivation, strategy, Giraffe pipeline data reduction, organisation, and workflow. Methods. We made use of the information recorded and archived in the observing blocks; during the observing runs; in a number of relevant documents; in the spectra and master catalogue of spectra; in the parameters delivered by the analysis nodes and the working groups; in the final catalogue; and in the science papers. Based on these sources, we critically analyse and discuss the output and products of the Survey, including science highlights. We also determined the average metallicities of the open clusters observed as science targets and of a sample of clusters whose spectra were retrieved from the ESO archive. Results. The Gaia-ESO Survey has determined homogeneous good-quality radial velocities and stellar parameters for a large fraction of its more than 110 000 unique target stars. Elemental abundances were derived for up to 31 elements for targets observed with UVES. Lithium abundances are delivered for about 1/3 of the sample. The analysis and homogenisation strategies have proven to be successful; several science topics have been addressed by the Gaia-ESO consortium and the community, with many highlight results achieved. Conclusions. The final catalogue will be released through the ESO archive in the first half of 2022, including the complete set of advanced data products. In addition to these results, the Gaia-ESO Survey will leave a very important legacy, for several aspects and for many years to come

Desempenho de forrageiras hibernais sob distintos níveis de luminosidade Performance of hibernal forages under distinct brightness levels

Objetivou-se determinar os possíveis efeitos da restrição de luminosidade, obtida com distintas densidades de árvores de Pinnus taeda, sobre a produção e qualidade de: aveia-preta (Avena strigosa Schreb) cv. Comum, aveia-branca (Avena sativa L.) cv. Fapa 2, azevém (Lolium multiflorum L.) cv. Comum, trigo (Triticum aestivum L.) duplo propósito cv. BRS Tarumã e ervilhaca peluda (Vicia villosa L.). Avaliaram-se três níveis de luminosidade: a sol aberto (sem presença de árvores de Pinnus taeda), 30% de restrição de radiação (usando espaçamento entre árvores de 15 × 3 m, com 222 árvores/ha) e 60% de restrição de radiação (usando espaçamento de 9 × 3 m, com 370 árvores/ha). Foram realizadas avaliações da produção de forragem, da composição química e dos componentes estruturais das plantas, do potencial hídrico das plantas, da umidade do solo, das variáveis microclimáticas e da produção de acículas. O delineamento experimental foi de blocos completos ao acaso, em parcelas subdivididas e três repetições. O azevém foi a espécie mais produtiva em todos os níveis de luminosidade, embora a ervilhaca tenha apresentado a menor redução de produção quando sombreada. Houve maior potencial hídrico nas plantas e maior umidade no solo nos ambientes sombreados, mesmo assim, a produção de forragem reduziu significativamente no sombreamento mais intenso (81%). A composição química e os componentes estruturais de todas as forrageiras estudadas também são afetados pelo aumento da restrição luminosa.<br>Possible effects of brightness restriction, obtained by different Pinnus taeda tree densities, on the production and quality of black oat (Avena strigosa Schreb) cv. Common, white oat (Avena sativa L.) cv. FAPA 2, annual ryegrass (Lolium multiflorum L.) cv. Common, hairy vetch (Vicia villosa), wheat (Triticum aestivum L.) cv. dual purpose BRS Tarumã were studied. It was evaluated three brightness levels: 1 - full sunlight with no trees; 2 - 30% of radiation restriction, using 15 × 3 m spacing between trees (222 trees/ha), and; 3 - 60% of radiation restriction, using 9 × 3 m between trees (370 trees/ha). It was performed evaluations of forage production, chemical composition and structural component of plants, water potential of the plants, soil moisture, microclimate variables and production of needles. The experimental design was completely randomized blocks, in split-plots and three replicates. Ryegrass was the most productive species at all brightness levels, although hairy vetch showed the lowest reduction on production under shading. There was higher water potential in the plants and higher soil moisture under shading, however, forage production was significantly reduced in the most intense shading (81%). Chemical composition and structural components of all studied forage species are also affected by brightness restriction increase

Decomposição de serrapilheira em bosque de sabiá na Zona da Mata de Pernambuco Litter decomposition under a sabiá canopy in the Forest Zone in Pernambuco

Objetivou-se avaliar a decomposição de frações de serrapilheira de sabiá (Mimosa caesalpiniifolia Benth) utilizando-se a técnica de sacos de náilon. Foram incubadas as seguintes frações de serrapilheira: folha senescente, folha no início da mineralização e ramos com até 20 mm de diâmetro. A incubação foi realizada nos períodos de 0, 4, 8, 16, 64, 100 e 256 dias nos anos de 2006 e 2007. As frações foram distribuídas em blocos ao acaso com cinco repetições. Foram avaliados os desaparecimentos de biomassa, nitrogênio (N) e fósforo (P), as concentrações de nitrogênio e fósforo e a relação carbono/ nitrogênio da serrapilheira ao longo dos períodos de incubação. De modo geral, o modelo exponencial negativo explicou o desaparecimento de biomassa, nitrogênio e fósforo, todavia, houve variação entre anos e, em alguns casos, apesar de significativos, os modelos apresentaram baixa correlação entre dados observados e preditos. A taxa de desaparecimento de biomassa foi lenta, uma vez que apenas 30% de biomassa de folhas foi mineralizada após 256 dias de incubação. A mineralização líquida de nitrogênio apresentou ampla variação entre anos e diferiu entre as frações estudadas. O teor de nitrogênio da serrapilheira incubada aumentou, em média, até os 32 dias (folhas) e até os 64 dias (ramos) de incubação, estabilizando-se em seguida. Foi usado o modelo platô linear para explicar esse processo. Com o passar dos períodos de incubação, a relação carbono/ nitrogênio diminuiu. Apesar de elevado teor de nitrogênio, a decomposição da serrapilheira de sabiá é lenta, o que pode reduzir as perdas de nutrientes no bosque, aumentando sua sustentabilidade e reduzindo os possíveis efeitos deletérios ao ambiente.<br>The research aimed to evaluate the decomposition of sabiá (Mimosa caesalpiniifolia Benth) litter fractions by using the nylon bag technique. The following litter fractions were incubated: senescent leaves, leaves at the beginning of mineralization, and branches with diameter up to 20 mm. Incubation was performed during periods of 0, 4, 8, 16, 64, 100, and 256 days in 2006 and 2007. The fractions were distributed in a random block design with five replications. It was evaluated the disappearance of biomass, nitrogen (N), and phosphorus (P), concentrations of nitrogen and phosphorus and the carbon/ nitrogen ratio of litter during the periods of incubation. In general, the negative exponential model explained the disappearance of biomass, nitrogen, and phosphorus, however, there was a variation among years and, in some cases, despite of being significant, the models showed a low correlation between predicted and observed data. Biomass disappearance rate was slow because only 30% of leaf biomass was mineralized after 256 days of incubation. Net nitrogen mineralization showed large variation among years, and it differed among the studied fractions. Nitrogen content of the litter increased, on average, until 32 days (leaves) and until 64 days (branches) of incubation followed by stabilization. The linear plateau model was used to explain that process. In the course of the incubation periods, the carbon/nitrogen ration decreased. Despite of the high content of nitrogen, the decomposition of sabiá litter is slow, what might reduce the loss of nutrients in the forest, increasing its sustainability and reducing the possible deleterious effects to the environment
