Techreport Reference D2.1 - Literature review on past accident
Maritime transport of Hazardous and Noxious Substances (HNS) has increased for 20 years, involving the risk of major pollution accidents with potentially more hazardous than oil. Chemicals may involve long-term environmental effects and the risks for public safety can be more severe for chemical releases (European Maritime Safety Agency [EMSA], 2007). Approximately 2,000 chemicals are transported by sea and only a few hundred chemicals are transported in bulk, but it represents the main volume of the chemical trade (Purnell, 2009). Alongside the expansion of chemicals transported at sea, incidents involving chemical tankers increased accordingly. Still, information on past and more recent incidents is not easily available. Furthermore, in the case of marine accident involving HNS, spill response is difficult due to the chemicals spilled, particularly when gas or volatile substances are released. The vapour cloud created can be toxic, flammable or explosive and there is a necessity to protect the crew, the population nearby as well as the environment and the stakeholders involved in marine pollution response. As an example, Figure 1 shows a picture of the explosion which occurred in September 2019 in the Ulsan harbour, South Korea. This explosion is the consequence of a styrene monomer leak on the chemical tanker Stolt Groenland that led to a massive explosion with fireball and mushroom cloud. The present report is a literature review on past accidents that have induced the formation of a toxic, flammable or explosive gas cloud. The information gathered will allow better identification of 1) the categories of chemicals most involved; 2) the main risks generated by the gas cloud dispersion in the air and 3) the consequences of a chemical slick on fire at the water surface as well as the hazard due to a vapour cloud explosion. This work is part of WP2: Enhancing knowledge and data on gases and evaporators of the MANIFESTS program (Managing risks and impacts from evaporating and gaseous substances to population safety) that studies risks associated to accidental chemical spills in the marine environment. The aim of this WP is to contribute to a better prediction of the consequences of vapour clouds due to marine accidents. This would facilitate the intervention of marine pollution organisms and would also help to protect population nearby, as we would know precisely where the dangerous area is.

Techreport Reference D4.1 Explosive risk and fire module
Responding to maritime accidents can be extremely challenging when involving HNS that behave as evaporators. Due to their potential to form toxic or combustible clouds, evidence-based decisions are needed to protect the crew, responders, the coastal population and the environment. However, when an emergency is declared, key information is not always available for all the needs of responders. A case in point is the lack of knowledge and data to assess the risks that responders or rescue teams could take when intervening, or those that could impact coastal communities when allowing a shipping casualty to dock at a place of refuge. The MANIFESTS project aims to address these uncertainties and improve response and training capacities through the development of an operational decision-support system (DSS) for volatile HNS spills. Besides management and communication, the project includes four other work packages: WP2 on collecting new data on evaporators, WP3 on table top exercises and field training, WP4 on improving modelling tools and WP5 on the development of the DSS. Key expected outcomes include: · Operational guidance; · Desktop and field exercises; · In situ training; · Experimental data on gas cloud fate; · A brand-new fire and explosion modelling module; · Improved HNS database with new experimental data on evaporation/dissolution kinetics. This report presents the results obtained in the framework of the task 4.1 aiming at developing tools that would help responders to asses risks in case of explosion and of fire of volatile HNS. The fire module computes the energy flux as a function of the distance to the fire source. It is useful to assess the safety distance at which e.g. a boat can approach a fire while keeping the crew safe. The energy flux can cause burning to people, and start new fire. The burning rate is also estimated. The explosion module computes the overpressure of the shockwave caused by the combustion of a chemical. This overpressure can be very dangerous for people and structure, causing wounds from minor injury to death and destruction of building. The model could be used to predict what could happen in case of the explosion of a stored explosive for instance. The two models are simplifications of the reality and do not take everything into account. Their results can be useful to have a rough idea of what could happen in open sea but should always be interpreted keeping the model hypotheses and limitations in mind. Due to the sensitivity of the topic, the source code of both modules is not made available to public

Article Reference Binkhorstiidae, a new family of crabs (Decapoda, Brachyura, Retroplumoidea) from the upper Cretaceous of the Netherlands and Belgium.
In addition to the type species, Binkhorstia ubaghsii, which is fairly common in the upper part of the Nekum Member (Maastricht Formation) in the wider vicinity of Maastricht (the Netherlands) and Binkhorstia euglypha, which appears to be restricted to the overlying Meerssen Member of the same formation (uppermost Maastrichtian), a third member, B. desaegheri nov. sp., is recorded from the upper middle Santonian of the Campine area in north-east Belgium. The history of Binkhorstia is convoluted, serving as a prime example of how attempts to unravel the higher-level taxonomic position of late Mesozoic crabs may prove difficult. Over time, the genus has been referred to various families or subfamilies, either podotreme or putative eubrachyuran; here the new family Binkhorstiidae is placed in the superfamily Retroplumoidea. Binkhorstiids appear to have been a relatively short-lived endemic group that fell victim to Cretaceous‒Paleogene (K/Pg) boundary perturbations.

Inproceedings Reference To colour or not to colour: Colour patterns and pigments in Invertebrates from the Palaeozoic of Belgium.
Almost nothing is known about the evolution of shell colour in invertebrates. This is largely due to the ultra-rarity of fossils in which colour patterns and pigments are preserved and immediately visible, and therefore easy to identify, especially when these are hundreds of millions of years old. This hampers our understanding of the role and function of colour in extinct animals, their ecology, mode of life, interactions, development, and evolution. A good example for this ultra-rarity is the Palaeozoic of Belgium, world-renowned for its exquisitely preserved fossils of the Devonian and Carboniferous, enabling to document major transitions in ecosystem dynamics and the evolution of life on Earth (e.g. nekton revolution, terrestrialisation, major climate changes, anoxic events, biodiversity crises) but from which only a few cephalopod, bivalve and gastropod mollusc and brachiopod shells were historically documented preserving coloured traces (mostly by L.-G. de Koninck and P. de Ryckholt, mid to late 19th century). However, recently, it was discovered that many more specimens preserve these traces, in particular those from Tournaisian–Viséan shallow marine reef environments, allowing to investigate its occurrence in different evolutionary lineages of marine invertebrates exactly during one of the main periods of revolution in geologic history. In Brain project B2/P233/P2 nicknamed COLOURINPALAEO financed by Belspo, after gathering all the specimens available in the main Belgian collections, we will use different techniques (multispectral photogrammetry and spectro-imaging) to better visualise the preserved colour patterns and pigments. Furthermore, advanced spectroscopic techniques, namely Raman micro-probe spectroscopy, synchrotron trace elemental mapping and absorption spectroscopy, will be used to identify the chemical signature of the pigments as well as their mode and pathways of preservation. Some of the first results on this multidisciplinary study on a unique set of Belgian fossils will be presented.

Article Reference A survey of transposon landscapes in the putative ancient asexual ostracod Darwinula stevensoni
How asexual reproduction shapes transposable element (TE) content and diversity in eukaryotic genomes remains debated. We performed an initial survey of TE load and diversity in the putative ancient asexual ostracod Darwinula stevensoni. We examined long contiguous stretches of DNA in clones from a genomic fosmid library, totaling about 2.5 Mb, and supplemented these data with results on TE abundance and diversity from an Illumina draft genome. In contrast to other TE studies in putatively ancient asexuals, which revealed relatively low TE content, we found that at least 19% of the fosmid dataset and 26% of the genome assembly corresponded to known transposons. We observed a high diversity of transposon families, including LINE, gypsy, PLE, mariner/Tc, hAT, CMC, Sola2, Ginger, Merlin, Harbinger, MITEs and helitrons, with the prevalence of DNA transposons. The predominantly low levels of sequence diversity indicate that many TEs are or have recently been active. In the fosmid data, no correlation was found between telomeric repeats and non-LTR retrotransposons, which are present near telomeres in other taxa. Most TEs in the fosmid data were located outside of introns and almost none were found in exons. We also report an N-terminal Myb/SANT-like DNA-binding domain in site-specific R4/Dong non-LTR retrotransposons. Although initial results on transposable loads need to be verified with high quality draft genomes, this study provides important first insights into TE dynamics in putative ancient asexual ostracods.

Article Reference Octet Stream The worked bone industry and intrusive fauna associated with the prehistoric cave burials of Abri des Autours (Belgium)
ABSTRACT The excavation of the Abri des Autours, a rock-shelter located in southern Belgium, enabled the discovery of three human burials, two dated to the Early Mesolithic and a third dated to the Middle Neolithic. In addition to the human bones, more than 200 faunal remains were uncovered. A taphonomic analysis was undertaken to determine whether their presence resulted from anthropogenic activities and whether they are linked to the burials. Two assemblages were distinguished. The majority of the fauna corresponds to remains of animals found scattered throughout the cave, including in the Mesolithic levels. These are mainly portions of carcasses brought in to the rockshelter by scavengers or predators. Therefore, their deposition did not result from human activity. Thus far, no animal bone had been found in direct association with Mesolithic burials in Belgium, and this site conforms to that pattern. Moreover, this interpretation corroborates the archaeological study, which did not uncover any traces of domestic activity in the cave, during either the Mesolithic or the Neolithic. On the other hand, several bone artefacts, including various tools and a pendant, were also identified. With the exception of an isolated artefact, all of these were clearly associated with the Middle Neolithic burial (Michelsberg culture). This is only the fourth Neolithic cave burial to have yielded animal bone artefacts in Belgium. A preliminary micro-wear analysis has confirmed that these objects had been used before being deposited and has allowed us to propose several hypotheses concerning their original use.
