This study assesses the seabed pressure of towed fishing gears and models the physical impact (area and depth of seabed penetration) from trip-based information of vessel size, gear type, and catch. Traditionally fishing pressures are calculated top-down by making use of large-scale statistics such as logbook data. Here, we take a different approach starting from the gear itself (design and dimensions) to estimate the physical interactions with the seabed at the level of the individual fishing operation. We defined 14 distinct towed gear groups in European waters (eight otter trawl groups, three beam trawl groups, two demersal seine groups, and one dredge group), for which we established gear “footprints”. The footprint of a gear is defined as the relative contribution from individual larger gear components, such as trawl doors, sweeps, and groundgear, to the total area and severity of the gear's impact. An industry-based survey covering 13 countries provided the basis for estim...

O presente trabalho busca propor uma abordagem dos documentos históricos utilizados em análises arqueológicas na qual as dimensões materiais desses artefatos são compreendidas enquanto relevantes. Nesse sentido são discutidos aqui a caligrafia de diários de bordo e pessoais de navios dos séculos XVIII e XIX bem como a estrutura e formatação de textos acadêmicos a fim de produzir reflexões sobre técnica, arte, beleza, função e agência de não-humanos nos processos de produção dos textos.
