... It is therefore unrealistic to place in priority order the proposed research solely on the basis of perceived relative importance. The committee suggests that the research proposed in this report be undertaken in general accordance with its position in the following matrix, which recognizes that some studies are prerequisite to others and that, in the Arctic, logistics commonly govern what is possible and when.

... , highresolution seismic reflection profiles, and continental shelf drilling · Gas hydrate studies requiring multichannel seismic reflection and refraction data and samples from cores or shallow drill holes on outer shelves or upper slopes in seasonally sea-icefree or light sea-ice areas · Paleobiogeographic and paleoecologic research requiring samples from onshore outcrops or from shallow cores and drill holes on the continental shelf · Ice-rafted sediment studies that require satellite imagery and samples from sea-ice and shallow subseabed cores Research in Category 1C · Paleoenvironmental indicator research requiring samples from onshore outcrops, shallow cores, or drill holes on the continental shelf Research in Category 2A · Seismic reflection and seismic refraction studies of Arctic Ocean Basin ridges and subbasins (prerequisite to coring and drilling) o Geophysical studies along continental margin transects (prerequisite to coring and drilling)

... 58 OPPORTUNITIES AND PRIORITIES IN ARCTIC GEOSCIENCE Ocean Basin ridges, subbasins, and continental margins; parts of the proposed arctic ice-rafted sediment, sedimentation, paleobiogeographic and paleoecologic, and gas hydrate and offshore permafrost studies, and the magnetostratigraphy of arctic cores; and all the stratigraphic and paleoenvironmental projects that require samples from the subseabed beyond the continental shelf · Deep crustal refraction experiments · Heat flow measurements Research in Category 2C · Paleoenvironmental indicator studies requiring samples from cores and shallow drill holes beyond the continental shelf · Search for evidence of possible solar-terrestrial interactions in the sedimentary record in the Arctic Research in Category 3B · All projects that require samples from drilling deeper than about 100-m subseabed at sites beyond the continental shelf, including some of the proposed gas hydrate studies, and all proposals that look toward eventual stratigraphic and paleoenvironmental deep drilling in the Arctic Ocean Basin beyond the continental shelf
