Publications in the pipeline

Wessex Archaeology - Fri, 2014-10-17 09:38
Two new publications will be available in November – excavations along the A46 with our partners Cotswold Archaeology and industrial archaeology at Hoyle Street, Sheffield. 

A46 NottinghamshireThe A46 trunk road in Nottinghamshire has its origins as the Roman Fosse Way. Archaeological work ahead of road improvements between Newark and Widmerpool undertaken by Cotswold Wessex Archaeology, has shed light on both Roman and pre-Roman use of this land. A number of significant sites were revealed, including evidence for Late Upper Palaeolithic flintwork at Farndon Fields on the gravel terrace south of Newark. This nationally important site comprised scatters of debris left in situ by a flint-knapper of the Creswellian and Federmesser hunter-gather cultural traditions. At Stragglethorpe there was a ring-ditch with a number of inhumation burials of Beaker date. Iron Age and Roman settlement in the hinterland around the Roman small town of Margidunum near Bingham was also investigated. Further to the south-west near Saxondale, Roman roadside enclosures became the location of early Anglo-Saxon cremation burials and perhaps also a ‘tumulus’, as recorded by William Stukeley in 1722 in the middle of the Fosse Way. 

Hoyle StreetExcavations in 2006–08 by ARCUS (Archaeological Research and Consultancy at the University of Sheffield), and now published by Wessex Archaeology, revealed a complex industrial site which sheds light on steelmaking and the conditions that workers lived and worked in. Historical research, building recording and archaeological excavation revealed the complex history of the site that in 1800 was still surrounded by fields on the town’s north-western edge, but which soon after was swallowed up by the steelworks, foundries and workers’ housing. Sheffield’s burgeoning population provided the workforce for the series of industrial premises – Roscoe Place Works, William Hoole’s Works (later Malinda Works), Hoyle Street Works, Progress Works, Titanic Works and Australian Works.  These industrial complexes were located among the cramped housing of the local working populations, and a number of cellars belonging to the back-to-back tenements and terraced houses were excavated, revealing evidence of possible cottage industry.  Available in November 2014, buy online from Oxbow Books To learn more about our publications follow this link

Microfossils reveal warm oceans had less oxygen, according to Syracuse geologists

Heritage Daily - Thu, 2014-10-16 12:13
Professor Zunli Lu uses geochemistry and micropalaeontology to track oxygen levels in global oceans.

Researchers from Syracuse University’s College of Arts and Sciences are pairing chemical analyses with micropalaeontology- the study of tiny fossilised organisms- to obtain a better understanding of how global marine life was affected by a rapid warming event over 55 million years ago.

Their findings are the subject of an article published in the journal Paleocenography (John Wiley & Sons, 2014).

“Global warming impacts marine life in complex ways, of which the loss of dissolved oxygen [a condition known as hypoxia] is a growing concern,” says Zunli Lu, assistant professor of Earth sciences and a member of Syracuse’s Water Science and Engineering Initiative. “Moreover, it’s difficult to predict future deoxygenation that is induced by carbon emissions, without a good understanding of our geologic past.”

Lu says this type of deoxygenation results in larger and thicker oxygen minimum zones (OMZs) in the wold’s oceans. An OMZ is the layer of water in an ocean where oxygen saturation is at its lowest.

Much of Lu’s work revolves around the Paleocene-Eocene Thermal Maximum (PETM), a well-studied analogue for modern climate warming. Documenting the expansion of OMZs during the PETM is problematic due to the lack of a sensitive, widely applicable indicator of dissolved oxygen.

In order to address the problem, Lu and his colleagues have started working with iodate, a type of iodine that is apparent in oxygenated waters only. By analysing the iodine-to-calcium ratios in microfossils, they are able to estimate the oxygen levels because of the lack of sensitive widely applicable indicator of dissolved oxygen.

Fossil skeletons of a group of protists known as foraminiferas have long been used for palaeo-environmental reconstructions. Developing an oxygenated proxy for foraminifera is important to Lu because it could allow him to study the extent of OMZs “in 3-D,” since these popcorn-like organisms have been abundant in ancient and modern oceans.

“By comparing our fossil data with oxygen levels simulated in climate models, we think OMZs were much more prevalent 55 million years ago than they are today,” he says, adding that OMZs likely expanded in the PETM, prompting mass extinction on the seafloor.”

Lu thinks analytical facilities that combine climate modeling with micropalaeontology will aid scientists in anticipating trends in ocean deoxygenation. Already, it’s been reported that modern-day OMZs, such as those in the Eastern Pacific Ocean, are beginning to expand. “They’re natural laboratories for research,” he says, regarding the interactions between oceanic oxygen levels and climate changes.
