Lead net-sinkers as an indicator of fishing activities
- Lead fishing-net sinkers in the shape of a small tube, ring, or folded piece of lead sheeting are often identified as scrap metal and/or treated only cursorily in many archaeological reports from Rome’s NW provinces.1 Very few have been illustrated, and measurements and weights are rarely noted. This has led to an under-representation of these finds in the archaeological record. By correctly identifying these lead artefacts and providing the necessary context information, archaeologists can facilitate insights into the various fishing techniques of antiquity and the places where they were practised. This will add information on the local and regional ecology and economy, as well as on dietary habits. Moreover, because the extensive use of lead in the NW provinces began only in the Roman period, finds of lead net-sinkers from well-documented contexts can be used to date indigenous settlements into the Roman period even if they otherwise yield few Roman artefacts. These facts motivated our article, which is therefore not an overview but rather a starting point for research on this artefact type in the NW provinces. We will also raise some questions for future research.

Influence of sedimentological variation on reservoir and source rock characteristics in shale dominated cyclothems (Campine Basin, NE Belgium)
- The KB186 well (GSB 047W0264, Lommel-Kerkhoven) is situated in the northern part of the Campine Basin (NE Belgium) to the west of the Donderslag fault and has been studied and sampled in detail from a depth of 1182.72 meters to 1197.75 metres. The objective is to examine the sedimentological, petrographical, mineralogical and petrophysical characteristics and their variations within and between two cyclothems. 17 shale samples were taken throughout the entire section, varying from roof shales, over dark organic-rich shales with siderite enrichments, to bluish-grey shales without no visible organic content. Two sedimentary cycles have been recognised. Macroscopically, they show some similarities and differences in facies and sedimentological trends. Both are approximately 6.5 metres thick and contain sections of mainly shale deposits (with or without siderite enrichments). Fining-upwards sequences of fine sand and clayey silt and larger sandstone bodies occur between these shale-rich sections. A petrographical assessment by means of optical light and electron microscopy is conducted for a qualitative analysis of the mineralogical composition and diagenetic history, while a quantitative determination is made by means of x-ray diffractometry. Important mineralogical reservoir parameters are the relative amounts of silica and quartz, and the clay mineralogy with special attention to smectite and illite.

Etude minéralogique des sédiments loessiques d'Etricourt-Manancourt : comparaison des teneurs en amphiboles vertes avec celles des loess belges
- L’étude minéralogique de sédiments loessiques d’Etricourt-Manancourt est menée dans le cadre d’une collaboration ponctuelle entre le Service Public de Wallonie et l’INRAP. Le matériel provient d’une série sédimentaire représentant une période allant de -300.000 à -80.000 ans, dans laquelle au moins cinq occupations préhistoriques ont été mise au jour lors de travaux de prospection préalables à la construction du canal Seine-Nord-Europe. L’objectif de cette étude est de comparer les teneurs en amphiboles vertes des dépôts loessiques d’Etricourt-Manancourt avec ceux étudiés en Belgique, afin d’évaluer la pertinence de l’extension du modèle minéralo-stratigraphique établi en Belgique vers la France.

Belgian report of the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA 18) of the Convention on Biological Diversity, Montreal, Canada, 23 – 28 June 2014
- The Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) of the Convention on Biological Diversity was established as an open-ended intergovernmental scientific advisory body of the Conference of the Parties (COP) and is to report regularly to the COP on all aspects of its work. Its functions include: providing assessments of the status of biological diversity; assessments of the types of measures taken in accordance with the provisions of the Convention; and respond to questions that the COP may put to the body. How SBSTTA carries out its work is described in its modus operandi, which can be found in Annex 1 of decision IV/16, as amended by decision V/20. To date, SBSTTA had met 17 times to date and produced a total of 179 recommendations to the Conference of the Parties, some of which have been endorsed in full by the latter. Such endorsement makes these recommendations de facto decisions of the Conference of the Parties. Parts of other recommendations have also been endorsed, and many others have been taken up in modified form. The eighteenth meeting of the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA 18) took place from 23 to 28 June 2014, at the International Civil Aviation Organisation (ICAO), Montreal, Canada, and was preceded, on Sunday 22 June, by an EU consultation meeting. The Belgian delegation consisted of: • Hendrik SEGERS (SBSTTA NFP, head of delegation, Royal Belgian Institute of Natural Sciences) • Catherine DEBRUYNE (Direction Générale de l'Agriculture, des Ressources Naturelles et de l'Environnement, Service Public de Wallonie) • Hilde EGGERMONT (Belgian Biodiversity Platform) • Kelly HERTENWEG (Federal Public Service Health, Food Chain Safety and Environment) • Sophie MIRGAUX (Federal public service health, food chain safety and environment) • Marianne SCHLESSER (Royal Belgian Institute of Natural Sciences) • Marie-Lucie SUSINI (Royal Belgian Institute of Natural Sciences)
