Sea-level changes in Iceland and the influence of the North Atlantic Oscillation during the last half millennium

We present a new, diatom-based sea-level reconstruction for Iceland spanning the last -500 years, and investigate the possible mechanisms driving the sea-level changes. A sea-level reconstruction from near the Icelandic low pressure system is important as it can improve understanding of ocean-atmosphere forcing on North Atlantic sea-level variability over multi-decadal to centennial timescales. Our reconstruction is from Viarhólmi salt marsh in Snæfellsnes in western Iceland, a site from where we previously obtained a 2000-yr record based upon less precise sea-level indicators (salt-marsh foraminifera). The 20th century part of our record is corroborated by tide-gauge data from Reykjavik. Overall, the new reconstruction shows ca0.6m rise of relative sea level during the last four centuries, of which ca0.2m occurred during the 20th century. Low-amplitude and high-frequency sea-level variability is super-imposed on the pre-industrial long-term rising trend of 0.65m per 1000 years. Most of the relative sea-level rise occurred in three distinct periods: AD 1620-1650, AD 1780-1850 and AD 1950-2000, with maximum rates of ~3±2mm/yr during the latter two of these periods. Maximum rates were achieved at the end of large shifts (from negative to positive) of the winter North Atlantic Oscillation (NAO) Index as reconstructed from proxy data. Instrumental data demonstrate that a strong and sustained positive NAO (a deep Icelandic Low) generates setup on the west coast of Iceland resulting in rising sea levels. There is no strong evidence that the periods of rapid sea-level rise were caused by ocean mass changes, glacial isostatic adjustment or regional steric change. We suggest that wind forcing plays an important role in causing regional-scale coastal sea-level variability in the North Atlantic, not only on (multi-)annual timescales, but also on multi-decadal to centennial timescales.

From Beijing with love: The global dimension of Bertolucci’s The Last Emperor

Famous for being the first foreign feature film that obtained permission to shoot in the Forbidden City, The Last Emperor (1987) is also one of the most ambitious and expensive independent productions of its time, awarded four Golden Globes and nine Academy Awards, including Best Picture. In addition, The Last Emperor can be considered as one of the first attempts of cinematic collaboration between West and East, in a period of cultural and economic transformations witnessed by China. This article aims to offer an overview of the production history of The Last Emperor, focusing on the co-production collaborations and the outcomes of a western auteur’s gaze on Chinese history. Questions of Orientalism, travel narrative and critical reception are taken into account in order to engage with the transnational implications of Bertolucci’s film and the western fascination with China.

Hydroclimatic shifts in northeast Thailand during the last two millennia - the record of Lake Pa Kho

The Southeast Asian mainland is located in the central path of the Asian summer monsoon, a region where paleoclimatic data are still sparse. Here we present a multi-proxy (TOC, C/N, δ¹³C, biogenic silica, and XRF elemental data) study of a 1.5m sediment/peat sequence from Lake Pa Kho, northeast Thailand, which is supported by 20 AMS ¹⁴C ages. Hydroclimatic reconstructions for Pa Kho suggest a strengthened summer monsoon between BC 170-AD 370, AD 800-960, and after AD 1450; and a weakening of the summer monsoon between AD 370-800, and AD 1300-1450. Increased run-off and a higher nutrient supply after AD 1700 can be linked to agricultural intensification and land-use changes in the region. This study fills an important gap in data coverage with respect to summer monsoon variability over Southeast Asia during the past 2000 years and enables the mean position of the Intertropical Convergence Zone (ITCZ) to be inferred based on comparisons with other regional studies. Intervals of strengthened/weaker summer monsoon rainfall suggest that the mean position of the ITCZ was located as far north as 35°N between BC 170-AD 370 and AD 800-960, whereas it likely did not reach above 17°N during the drought intervals of AD 370-800 and AD 1300-1450. The spatial pattern of rainfall variation seems to have changed after AD 1450, when the inferred moisture history for Pa Kho indicates a more southerly location of the mean position of the summer ITCZ.

Exploiting local controversy: regional British censorship of Last Tango in Paris (1972)

This article explores local authority responses to the cinematic release of Last Tango in Paris in Britain. Using a range of archival material from the BBFC, the National Archives and the Public Records Office of Northern Ireland, it offers a detailed, comparative case study of three different locations; Belfast, Newport and Oxford. It argues that comparing local censorship decisions with the national decisions of the BBFC offer little in the way of regional nuance. In order to effectively understand the workings of local censorship, a deeper understanding of local discourses is needed as well as acknowledgement of broader pressure group activity and its impact on the local picture, such as that of the National Festival of Light.
