Seagrass meadows provide a multitude of ecosystem services, including a capacity to sequester carbon dioxide (CO2) within their sediments. Seagrass research in the UK is lacking and there is no published data on sediment carbon (C) within UK seagrass meadows. We sampled 13 Zostera marina meadows along the southwest coast of the UK to assess the variability in their sedimentary organic carbon (OC) stocks. The study sites were considered representative of sub-tidal Z. marina meadows in the UK, spanning a gradient of sheltered to exposed sites, varying in formation, size and density, but found along the same latitudinal gradient. OC stocks (Cstocks) integrated across 100cm depth profiles were similar among all sites (98.01 ± 2.15 to 140.24 ± 10.27 Mg C ha-1), apart from at Drakes Island, which recorded an unusually high Cstock (380.07 ± 17.51 Mg C ha-1) compared to the rest of the region. The total standing stock of C in the top 100cm of the surveyed seagrass meadows was 66,337 t C, or the equivalent of 10,512 individual UK people’s CO2 emissions per year. This figure is particularly significant relative to the seagrass area, which totalled 549.79 ha. Using estimates of seagrass cover throughout the UK and recent UK C trading values we approximate that the monetary value of the UK’s seagrass standing C stock is between £2.6 million and £5.3 million. The C stock of the UK’s seagrass meadows represent one of the largest documented C stocks within Europe and are, therefore, of important ecosystem service value. The research raises questions concerning the reliability of using global or regional data as a proxy for local seagrass C stock estimates and adds to a growing body of literature that is looking to understand the mechanisms of seagrass C storage. When taken with the fact that seagrass meadows are an important habitat for commercially important and endangered species in the UK, along with their declining health and cover, this research supports the need for more robust conservation strategies for UK seagrass habitats.
Collaboration has risen up the agenda for archives and universities in recent years, yet there is unrealized potential for co-productive modes of research between archivists and academics, with business collections facing particular obstacles. This article, co-written by an archivist and a historian, presents the findings of a project that aims to support business archivists to develop co-designed research projects that mobilize business collections in rigorous ways to meet present-day business priorities (and so demonstrate to parent organizations the value of their archives and expert archivists). The project involved a collaborative process of workshops, interviews and a survey, which has allowed the project network to develop guidance materials. The authors discuss three key themes that emerged from the process, reflecting the distinctive concerns of archivists working in organizational repositories and the factors that influence their pursuit of academic collaborations. There then follows an analysis of 'mind-set' barriers to collaboration: questions of professional culture and practice or intellectual stance that can influence attitudes to and pursuit of collaborative projects between historians and archivists. The authors argue for an open and dialogic approach to designing collaborative research, acknowledging the constraints and imperatives for archivists and academics and recognizing the complementarity of their expertise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
