Abstract: This study aims to develop more accurate method for mapping closed canopy evergreen natural forest (CCEF) of the Eastern Arc Mountains (EAM) ecoregion in Tanzania and Kenya, to update the knowledge on its spatial extent, level of fragmentation and conservation status. We tested 1023 model possibilities stemming from combination of Sentinel-1(S1) and Sentinel-2(S2) satellite imagery, spatial texture of S1 and S2, seasonality derived from Landsat-8 time series and topographic information, using random forest modelling approach. The CCEF model has moderate accuracy measured in True Skill Statistic (0.57), and it clearly outperforms other similar products from the region. Based on this model, there are about 296000 ha of Eastern Arc Forests (EAF) left, which is 16-27% less than estimated by previous products. Furthermore, acknowledging small forest fragments (1-10 ha) implies that the EAFs are more fragmented than previously considered. The generated CCEF model should be used to design updates and more informed and detailed conservation allocation plans, to balance this situation Category: geoscientificInformation Source: Not Available Supplemental Information: Not Availble Coverage: EVENT LABEL: * LATITUDE START: -6.000000 * LONGITUDE START: 36.000000 * LATITUDE END: -10.000000 * LONGITUDE END: 34.000000 * METHOD/DEVICE: Multiple investigations

Abstract: Open pit exploitation of the Kirki high sulfidation epithermal deposit (Thrace, NE Greece) resulted in the formation of an acidic pit lake by infilling of the open cast by rain and draining waters after mine closure. Three case specific PHREEQC geochemical models were developed including "Direct Precipitation", "Evaporation", and "Mixing with Rain water" in order to simulate the environmental conditions through the year, and to investigate the behavior of the acidic and rich in heavy metals waters of the pit-lake. Scanning Electron Microscopy examination revealed the predominance of jarosite species and goethite in the mineral precipitate, followed by lower amounts of hematite, schwertmannite and anglesite. According to PHREEQC modeling, jarosite species formation is favored during both dry and wet periods, while the presence of schwertmannite, goethite, hematite and anglesite depicts the fluctuation of the physicochemical conditions through the year. These phases play a key role in controlling the As and Pb dissolved concentrations, mainly through adsorption and co-precipitation, whereas the soluble metals Zn, Cd and Mn remain dissolved. The current status of the Kirki open pit system is the most stable for the environment, therefore a case-specific remediation plan focused on both the protection of the environment and the preservation of the Kirki open pit is proposed. The socio-economic benefits of such an approach could include increased tourist numbers due to case-oriented tourism, enhancement of local economy, education, whereas this approach is also cost effective relative to other proposed remediation measures.

Abstract: We present station-specific depth integrated abundance and biomass of Calanus spp. (stage-specific abundance, CI-CVI, of C. finmarchicus, C. glacialis, C. hyperboreus and combined biomass of late stages, CIV-CVI, of Calanus spp.) collected from zooplankton monitoring programs from 19 subregions spanning the Newfoundland and Labrador Shelves, Gulf of St. Lawrence (GSL), Scotian Shelf, and Gulf of Maine (GoM). These data span years 1999-2016, except the southwest GSL subregion (1982-2016) and GoM (1977-2016). We also present data on near surface and bottom temperature and salinity from subregions in Canadian waters. We then present derived annual anomalies of abundance of the three species of Calanus, their combined biomass, and near surface and bottom temperature and salinity from all subregions. This is a contribution by Canadian and USA scientists and their institutions. Sampling and data processing methods are provided in detail in Sorochan et al. (2019), and zooplankton sampling methods are summarized here. Zooplankton samples from the southwest GSL subregion were collected from the DFO mackerel egg production survey (Mackerel Survey) using a 0.61-m diameter bongo frame (0.333-µm mesh) towed obliquely to the surface from a maximum sampling depth that varied among years, but was usually > 50 m. All other samples from Canadian waters were collected as part of the DFO Atlantic Zone Monitoring Program (AZMP) using a 0.75-m diameter ring net (202-µm mesh) towed vertically to the surface from a depth of ~ 5 m above bottom or a maximum depth of 1000 m. Samples from the GoM were collected from the NOAA Marine Resources Monitoring, Assessment and Prediction and Ecosystem Monitoring Surveys (EcoMon), which used the same gear as the Mackerel Survey, but sampled from a depth of ~ 5 m above bottom or a maximum depth of 200 m. These data were supplemented with surveys from the western GoM, which used sampling methods identical to AZMP. When samples were not collected from near bottom to surface in the Mackerel Survey and EcoMon, the data were adjusted using a Generalized Additive Model to estimate the depth integrated abundance or biomass from near to bottom to surface. Annual anomalies correspond to those published in Sorochan et al. (2019) with exception of abundance and biomass of Calanus spp. from the GoM and southwest GSL, which have been slightly modified to reflect updates on the data inclusion and standardization. We also note that the linear model used to derive anomalies of Calanus spp. abundance and biomass in the GoM uses Month as a factor rather than Season, which was incorrectly reported in Table 3 of Sorochan et al. (2019). Category: geoscientificInformation Source: Not Available Supplemental Information: Not Availble Coverage: Not Available
