Pliocene seasonality across the North Atlantic inferred from cheilostome bryozoans

Previous studies have shown an inverse correlation between zooid size in cheilostome bryozoans and ambient water temperature. This relationship underlies the MART technique which uses intracolonial variation in zooid size to predict mean annual range in temperature experienced by bryozoan colonies during their life. Here we apply the MART technique to study Early and Mid Pliocene bryozoans from Central America (Panama, Costa Rica), the USA (Florida, South Carolina, North Carolina, Virginia) and the UK (Suffolk) to reconstruct palaeoseasonality across a range of latitudes for the North Atlantic during the Pliocene Epoch. Compared to the present-day, our analyses suggest greater seasonality (ca 4.5 degrees C) in the southern Caribbean at the time of Cayo Agua Formation deposition (ca 4.25 Ma), in keeping with inferred upwelling prior to the closure of the isthmian barrier at 2.7 Ma. Bryozoans also indicate seasonal upwelling on the Gulf Coast of Florida in a similar manner to the present-day. Because upwelling can be highly localised and prone to spatial and temporal variation in the Gulf of Mexico today, it contributes little to a broad understanding of Pliocene North Atlantic waters. However, MART estimates for the coastal plain region indicate a general reduction in the annual range in temperature relative to the present, suggesting that the colder surface waters that today reach south to Cape Hatteras had less influence in Early to Mid Pliocene times. These results, along with evidence from other proxies, strongly support reduced seasonality and warmer conditions along the eastern seaboard of the USA in the Early to Mid Pliocene. Finally, the MART estimates amongst Coralline Crag localities provide evidence for an increased annual range in temperature in the southern North Sea than at present. Our study shows that bryozoan MART estimates provide a powerful, independent proxy for palaeoseasonality and is the first to demonstrate that the MART technique can be applied to infer palaeoclimates across a wide range of latitudes focusing on a variety of geological formations and geographical regions.

‘Anything can happen in the next half-hour’: Gerry Anderson’s transnational science fiction

Gerry Anderson’s 1960s puppet series have hybrid identities in relation to their medial, geographical, and production histories. This chapter ranges over his science fiction series from Supercar (1961) to Joe 90 (1968), arguing that Anderson’s television science fiction in that period crossed many kinds of boundary and border. Anderson’s television series were a compromise between his desire to make films for adults versus an available market for children’s television puppet programs, and aimed to appeal to a cross-generational family audience. They were made on film, using novel effects, for a UK television production culture that still relied largely on live and videotaped production. While commissioned by British ITV companies, the programs had notable success in the USA, achieving national networked screening as well as syndication, and they were designed to be transatlantic products. The transnational hero teams and security organisations featured in the series supported this internationalism, and simultaneously negotiated between the cultural meanings of Britishness and Americanness. By discussing their means of production, the aesthetic and narrative features of the programs, their institutional contexts, and their international distribution, this chapter argues that Anderson’s series suggest ways of rethinking the boundaries of British science fiction television in the 1960s.

Creating a Diversity Movement in the University

What kind of actions can a university take to create a diversity movement within its confines? Taking recent work at North Carolina State University as the prototype, this session will be used to outline and discuss the characteristics of administrative action that can lead to a comprehensive and programmatic diversity movement within any college or university.
