    Description: A sediment core, collected from the western part of the continental slope of the Ross Sea at 2380 m water depth, records events of the last two climatic cycles (250 kyr). A 230Thex-based chronology was obtained and boundaries of the isotope stages were set assuming that biological productivity was enhanced during periods of less ice cover. Then, 230Thex0, organic carbon, biogenic silica and biogenic Ba distributions were compared to the glacial-interglacial stage boundaries and corresponding ages of the delta18O record of Martinson et al. [Martinson et al., 1987, doi:10.1016/0033-5894(87)90046-9]. Sediment accumulation rates ranged between 1.2 cm kyr**-1 in the isotope stage 6 and 3.8 cm kyr**-1 during the Holocene. Variations in the concentrations and fluxes of organic carbon, biogenic Ba, biogenic silica and Mn gave information on palaeoclimate changes. Processes of sediment redistribution in the Ross Sea margin were enlightened from a comparison of the measured and expected fluxes of 230Thex. Calculation of the focusing-corrected accumulation rates of biogenic Ba enabled us to evaluate the export palaeoproductivity. Corrected accumulation rates of biogenic components and calculated palaeoproductivities were low, compared to the Antarctic Polar Front in the Atlantic sector, throughout the last two climatic cycles. Glacial-interglacial changes of sea ice cover and ventilation of the Ross Sea were probably major causes of variations in biogenic particle flux and distribution of redox-sensitive elements within the sediment column.

    Description: In order to correctly understand the rates and mechanisms of biogeochemical cycling along the water column, special attention must be paid to data analysis techniques. We propose a revised procedure combining precision and practicality to minimize sample handling errors that would affect the determination of both mass fluxes and the composition of material collected by sediment traps in the Antarctic region. The key points to take in account are: (i) the mesh size used for removing “large” particles or aggregates (from 150 micron to 1 mm); (ii) the absence of filters; and (iii) the use of a microscope to pick out “swimmers”. We also recommend: removal of all swimmers using a 650-micron mesh; analysis using a stereomicroscope; and quantitative subdividing using a peristaltic pump.

    Description: The impact of tides in the circulation of the Adriatic Sea is investigated by means of a nested baroclinic numerical ocean model. Tides are introduced using a modified Flather boundary condition at the open edge of the domain. The results show that tidal amplitudes and phases are reproduced correctly by the baroclinic model and tidal harmonic constants errors are comparable with those resulting from the most consolidated barotropic models. Numerical experiments were conducted to estimate and assess the impact of (i) the modified Flather lateral boundary condition; (ii) tides on temperature, salinity, and stratification structures in the basin; and (iii) tides on mixing and circulation in general. Tides induce a different momentum advective component in the basin, which in turn produces a different distribution of water masses in the basin. Tides impact on mixing and stratification in the River Po region (northwestern Adriatic) and induce semidiurnal fluctuations of salinity and temperature, in all four seasons for the former and summer alone for the latter. A clear presence of internal tides was evidenced in the northern Adriatic Sea basin, corroborating previous findings.

    Description: Environmental - health debate is one of the most challenging and complex issue that authorities at local, national and international level have to deal with. Being characterized by a high level of uncertainty, interests and values at stake, the research activity in these fields requires an enlargement of subjects authorized to participate in definition of research questions, work methodologies, collection of relevant information, with a plurality of values and views inside and outside of science [1]. Topics are also covered in COP21, COP22, UN Agenda 2030. The demand of raising awareness about the role that women play in the research environment as professionals and in society at large as stakeholders may be particularly huge in environmental sciences for original contributions they can give [2,3]. The goal at large is to improve the awareness and the knowledge about gender dimension in environmental research, thus putting the basis of further concrete actions in this direction. Scientific research, but also dissemination, public engagement, best practice exchange and networking activities of women scientists associations contribute in reaching this goal. We share and integrate our experiences while promoting debates and synergies. We start from our work in different research performing organizations, and more specifically, from our experiences in research and communication in science and in the environmental field, embracing climate changes, ecology and biodiversity, pollution and health, earth sciences. Dissemination and networking activities of Associazione Donne e Scienza, the women scientists association in Italy, facilitates this process of raising awareness. Multiple gender dimensions exist. First dimension refers to the gender of researchers, from the few pioneers of the past to the huge number of women that today are active in the environment, its balance and health research providing original contributions. These contributions should be largely recognized for their implications - per se - as well as for stimulating new girls to scientific curricula [4,5]. Another dimension is that of gender differences in the environmental impact assessment. Several studies indicate how impacts of environmental pollution as well as of climate changes on women and men vary significantly, and this issue must be addressed when implementing policies [6]. Starting from our professional activities we found that gender analysis has enriched the interpretation of scientific results, avoiding to underestimate health problems and environmental balance, in one sex or another [7, 8, 9]. Moreover, one gender dimension refers to the epistemological level. New research approaches including citizen science and participatory approaches embody characteristics that several scholars consider feminist methods of research [10]. Last gender dimension is that of presence of many women in environmental organizations, a presence arising new research questions about environmental protection and healthcare. Gender analysis expands the boundaries and enriches the environmental and health research and may largely contribute to the environmental debate and new approaches to knowledge.

    Description: Stemming from experiences in research and communication in the environmental field (climate changes, pollution, earth sciences, …) some considerations about gender dimensions in environmental research are illustrated. Multiple gender dimensions exist, expanding the boundaries and enriching the research itself. First dimension refers to the gender of researchers, from the few pioneers of the past to the huge number of women that today are active in environmental research providing original contributions. Another dimension is that of gender differences in the impact of environmental changes: several studies indicate how impacts of climate changes on women and men vary significantly, and this issue must be addressed when implementing policies. Moreover, one gender dimension refers to the epistemological level, addressing the feminist approach to science, with situated knowledges and citizen science. Another dimension is that of presence of women in environmental organizations, a presence arising new research questions about environmental protection and healthcare.

    Description: La diffusione delle discipline STEM, il tema del genere e dell’educazione di qualità equa e inclusiva, obiettivi 4 e 5 dell’Agenda ONU 2030, sono fondamentali per l’attuale e la futura società. Questi temi sono da affrontare con metodi più attuali e accattivanti, capaci di superare le distanze fra i diversi attori sociali, e invogliare ragazze e ragazzi a intraprendere il loro percorso di studi e di vita nel mondo della ricerca o in quello dell’impresa, della didattica o della comunicazione e/o disseminazione. Viene illustrata una Rete per la parità di genere e la formazione di qualità, che comprende azioni e idee progettuali e che coinvolge diversi portatori d’interesse e associazioni che operano sul territorio, il mondo dell’università, degli Enti di ricerca e della scuola di ogni ordine e grado. La Rete ha l’obiettivo di condividere e integrare metodologie, esperienze e competenze diverse, rompere stereotipi di genere sulle abilità scientifiche e tecniche, e infine portare a tutte e tutti il messaggio che "ogni cosa è possibile" scegliendo le chiavi giuste per aprire le porte della conoscenza, dell'inclusione e dell'innovazione.
