The KANUMAS areas comprise the waters off Northeast and Northwest Greenland. This preliminary strate- gic environmental impact assessment forms part of this process and deals with the KANUMAS area in Northwest Greenland: the KANUMAS West area (Figure 1). A regional seismic exploration programme, the KANUMAS project, was initiated at the end of 1989, when a group of companies, the KANUMAS group, was granted a prospecting licence for the KANUMAS areas. The prospecting licence did not include any exclusive rights to the licensee and implied considerable obligations with regard to exploration. This was balanced by the KANUMAS group companies being granted a preferen- tial position in relation to potential petroleum exploration licencing in Northeast and Northwest Greenland. Interest in the KANUMAS areas increased substantially after the opening of the Disko West licensing round in the waters immediately to the south of KANUMAS West. The geology of the KANUMAS East area (Green- land Sea) is comparable to the offshore areas off West Norway, whereas the KANUMAS West area (Baffi n Bay) constitutes a northern geological extension of the Disko West licensing area. Preparation of the KANUMAS areas for possible future exploration and exploitation licencing requires that new knowledge in a number of areas is acquired in advance. This preliminary SEIA was prepared as a co-operation bewteen National Environmental Research Institute (NERI), Greenland Instutute of Natural Resources (GINR) and Bureau of Minerals and Petroleum (BMP). Before the fi nal SEIA is issued in 2010 this preliminary version will be subject to a public hearing process in Greenland. Acknowledgement Malene H.

Flemming Getreuer Christiansen (GEUS) supplied the potential drill sites for oil spill modelling. The sections on weather, oceanography and ice conditions are modifi ed from a DMI contribution to the oil spill sensitivity map covering the West Greenland region between 68° and 72° N (Mosbech et al. 2004). 5 Summary and conclusions This document is a preliminary Strategic Environmental Impact Assess- ment (SEIA) of activities related to exploration, development and exploi- tation of hydrocarbons in the sea off Northwest Greenland between 71° and 78° N. The KANUMAS West area (Figure 1). The KANUMAS project was a regional seismic exploration programme that was initiated at the end of 1989. A group of companies, the KANU- MAS group, was then granted a prospecting licence to the KANUMAS ar- eas. The Kanumas areas also encompass the Greenland part of the Green- land Sea – the KANUMAS East area. The prospecting licence did not include any exclusive rights to the licen- see. The licence implied a considerable obligation of exploration. This was balanced by granting the companies a special preferential position for the KANUMAS group. This preferential position will be activated if the right to petroleum exploration in Northeast and Northwest Greenland is put up for licensing. The SEIA was prepared by the National Environmental Research Institute, Denmark and the Greenland Institute of Natural Resources in cooperation with the Greenland Bureau of Minerals and Petroleum. The assessment area is shown in Figure 1. This is the region which poten- tially could be impacted by a large oil spill deriving from activities within the expected licence areas, although drift modelling indicates that oil may drift further than the extent of this area. The expected activities in the ‘full life cycle’ of a petroleum fi eld are briefl y described. Exploration activities are likely to take place during summer and autumn, because harsh weather and particularly sea ice hamper ac- tivities in winter and spring. However, if oil production is initiated activi- ties will take place throughout the year. The environment The physical conditions of the study area are briefl y described with fo- cus on oceanography and ice conditions. Sea ice and icebergs are present throughout the year, with the lightest conditions in the period July-Octo- ber. One of the most important physical features of the biological environ- ment is the polynyas (ice-free or almots ice-free areas surrounded by sea ice), of which the most important is the North Water between the Qaanaaq area and Ellesmere Island in Canada.
