Article Reference A generalized physics-based correction for adjacency effects
Atmospheric scattering occurs over a horizontal scale of several kilometers. This results in influence from neighboring surface features on the signal recorded over a given position, reducing contrast and the accuracy of quantitative retrievals of surface reflectance from satellite imagery. This atmospheric blurring, or adjacency effect, must be accounted for when both contrast in surface reflectance and magnitude of atmospheric scattering are significant. Taking into account the adjacency effect is of particular importance for aquatic remote sensing of inland and coastal waters due to the high contrast between water and different land cover types, as well as the small spatial scale of most inland water bodies. In this paper, we present a physics-based processor to retrieve surface reflectance over all surface types, regardless of the subscene composition and sensor waveband configuration. The processor is implemented in the free and open source ACOLITE software and is composed of two modules: (1) TSDSF for the estimation of aerosol properties and (2) RAdCor for the retrieval of surface reflectance. We demonstrate the performance of the TSDSF $+$ RAdCor processor for the Operational Land Imager (OLI) onboard Landsat 8 and the Multispectral Instrument (MSI) onboard Sentinel-2A and 2B over a set of small ($\lt1\;\rm km^2$) inland waters in Belgium, and compare the performance with other common processors for these sensors, including C2RCC, POLYMER, Sen2Cor, iCOR, ACOLITE/DSF, and LaSRC. For clear sky matchups, the relative deviation againstin situ data in the visible wavebands ranged between 6% and 18% for OLI, and between 14% and 31% for MSI, except for the MSI waveband centered at 443 nm where the relative deviation was 70%. In the near-infrared wavebands, the relative deviation varied from 70% to 150%, with the exception of the MSI waveband centered at 704 nm, for which the performance was 17%. Overall, the new processor outperformed the other evaluated processors in the visible range, with the exception of the MSI waveband centered at 443 nm, and was outperformed by C2RCC and POLYMER in the near-infrared wavebands. Recommendations on how to use TSDSF and RAdCor in ACOLITE are provided.

Article Reference A global approach for natural history museum collections
Integration of the world’s natural history collections can provide a resource for decision-makers Over the past three centuries, people have collected objects and specimens and placed them in natural history museums throughout the world. Taken as a whole, this global collection is the physical basis for our understanding of the natural world and our place in it, an unparalleled source of information that is directly relevant to issues as diverse as wildlife conservation, climate change, pandemic preparedness, food security, invasive species, rare minerals, and the bioeconomy (1). Strategic coordination and use of the global collection has the potential to focus future collecting and guide decisions that are relevant to the future of humanity and biodiversity. To begin to map the aggregate holdings of the global collection, we describe here a simple and fast method to assess the contents of any natural history museum, and report results based on our assessment of 73 of the world’s largest natural history museums and herbaria from 28 countries.

Article Reference A global meta-analysis on the drivers of salt marsh planting success and implications for ecosystem services
Planting has been widely adopted to battle the loss of salt marshes and to establish living shorelines. However, the drivers of success in salt marsh planting and their ecological effects are poorly understood at the global scale. Here, we assemble a global database, encompassing 22,074 observations reported in 210 studies, to examine the drivers and impacts of salt marsh planting. We show that, on average, 53% of plantings survived globally, and plant survival and growth can be enhanced by careful design of sites, species selection, and novel planted technologies. Planting enhances shoreline protection, primary productivity, soil carbon storage, biodiversity conservation and fishery production (effect sizes = 0.61, 1.55, 0.21, 0.10 and 1.01, respectively), compared with degraded wetlands. However, the ecosystem services of planted marshes, except for shoreline protection, have not yet fully recovered compared with natural wetlands (effect size = −0.25, 95% CI −0.29, −0.22). Fortunately, the levels of most ecological functions related to climate change mitigation and biodiversity increase with plantation age when compared with natural wetlands, and achieve equivalence to natural wetlands after 5–25 years. Overall, our results suggest that salt marsh planting could be used as a strategy to enhance shoreline protection, biodiversity conservation and carbon sequestration.

Article Reference A land micro-mammal fauna from the Early Eocene marine Egem deposits (NP12, Belgium) and the first occurrence of the peradectid marsupial Armintodelphys outside North America
Dental remains of land mammals are sometimes discovered in shallow marine Paleogene deposits of the North Sea Basin. Such is the case for eleven specimens we describe here from the Early Eocene Egemkapel Clay Member in the middle part of the Tielt Formation, found in Ampe quarry at Egem in Northwestern Belgium. The small fauna consists of 6 taxa, including the neoplagiaulacid multituberculate Ectypodus, the erinaceomorph insectivore Macrocranion, the nyctitheriid Leptacodon, an eochiropteran bat possibly belonging to a palaeochiropterygid, an unidentified perissodactyl possibly belonging to an equoid, and a new species of the peradectid marsupial Armintodelphys. The latter represents the first European occurrence of the genus, which was previously only known from the North American late Early and early Middle Eocene of the Wind River and Green River basins in Wyoming and the Uinta Basin in Utah. Biogeographic and biostratigraphic analyses of peradectid marsupials suggest that Armintodelphys dispersed between North America and Europe around the time of the Early Eocene Climatic Optimum. The Egemkapel Clay Member has been dated as middle NP12, early late Ypresian, whereas the Egem mammal fauna can be correlated to the fauna of Avenay from the Paris Basin, which is the international reference-level MP8+9 of the mammalian biochronological scale for the European Paleogene.

Article Reference A matter of scale: developing a framework for environmental archaeology in Brussels
Whereas environmental studies are today an important part of urban archaeological research in many towns and cities in Europe, they often focus on individual sites and do not always result in larger syntheses. To exploit the full potential of urban environmental studies in Brussels, Belgium, a specific framework has been developed, explicitly aimed at coping with the inherent complexity of urban investigations, including the variety of research themes that need to be dealt with, the challenges of fast-evolving environmental research, and how to address the needs of different stakeholders. This article discusses how the framework was created, the challenges that have been dealt with over the past few decades, and how we can further improve the framework for the future.
