Farthest North: Ocean Drilling in the Arctic Gateway Region Leg 151 Shipboard Scientific Party

ABSTRACT The Ocean Drilling Program (ODP) recently recovered the first deep-drilled sediment sequences from the Arctic Ocean, on Leg 151 in July–September 1993. The ODP drill- ship Resolution took advantage of late summer low-ice conditions in the region northwest of Svalbard to drill three sequences on the Yermak Plateau at lat ~80°N and long 5°–8°E. Despite being chased away several times by advancing sea ice, ODP Leg 151 successfully obtained the northernmost long sediment cores (>500 m) ever drilled. The sediment Figure 1.

GEOTRIP Scientific Leaders: Haraldur Sigurdsson, Graduate School of Oceanography, University of Rhode Island Iceland: Fire and Ice Haukur Johannesson, Natural History Institute, Reykjavik, Iceland July 16–30, 1995 • 14 days, 15 nights A native of Iceland and professor of oceanography, Haraldur Sigurdsson is a leading vol- canologist with an international reputation for his research on many aspects of vol- canism in Iceland, Italy, Mexico, Colombia, the United States, and Indonesia, among others. Haukur Johannesson has devoted most of his career to the geologic mapping of the uncharted volcanic regions of Iceland. He is an expert in the tectonic structure and origin of the Iceland basalt plateau and is also very knowledgeable about the nat- ural history of Iceland in general. Schedule July 16, Sunday ......
