Sea surface temperature and sea ice variability in the subpolar North Atlantic from explosive volcanism of the late thirteenth century

In this study, we use IP and alkenone biomarker proxies to document the subdecadal variations of sea ice and sea surface temperature in the subpolar North Atlantic induced by the decadally paced explosive tropical volcanic eruptions of the second half of the thirteenth century. The short- and long-term evolutions of both variables were investigated by cross analysis with a simulation of the IPSL-CM5A LR model. Our results show short-term ocean cooling and sea ice expansion in response to each volcanic eruption. They also highlight that the long response time of the ocean leads to cumulative surface cooling and subsurface heat buildup due to sea ice capping. As volcanic forcing relaxes, the surface ocean rapidly warms, likely amplified by subsurface heat, and remains almost ice free for several decades

Words, words, words: Philology and Beyond: Festschrift for Andreas Fischer on the Occasion of his 65th Birthday

This Festschrift comprises a series of papers written in honour of the philologist Andreas Fischer, on the occasion of his sixty-fifth birthday. As in Andreas Fischer s own research, the main focus of the volume is on words: words in modern varieties, such as emergent conjunctions in Australian, American and British English; words in their cultural and historical context, such as English keywords in Old Norse literature; and words in a diachronic perspective, such as Romance suffixation in the history of English. Many contributions are anchored in the philological tradition that has informed much of Andreas Fischer s own scholarship, such as the study of verbal duelling in the late thirteenth-century romance Kyng Alisaunder. Others examine the construction ofdiscourses, such as those surrounding the Black Death. The volume, with its innovative studies,offers fascinating insights into words, discourses,and their contexts, both past and present.
