The first was to determine interest and need for a biodiversity study in the Arctic, while the second discussed the joining of the longitudinal and latitudinal NaGISA transects with a transect that would cross the North Pacific/Bering Sea at the Aleutian Islands. Discussions during the Arctic biodiversity portion of the workshop identified what is known and what is unknown but knowable about diversity in the Arctic Ocean. An Arctic Biodiversity Transect was identified as being urgent since changes in environmental con- ditions have already happened, and Arctic biological communities are expected to have disproportionate responses to global climate change. The dependency of Native peoples on the Arctic ecosystem for subsistence lifestyle adds social and cultural urgency. How will the changes in the Arctic impact the biodiversity of sea ice communities on regional and temporal scales? For the sea ice system it was identified that delicate groups such as protozoan and metazoan meiofauna inhabiting the sea ice are among the least known groups. Little to no information is available on their species richness, distribution, and abundance. The sea ice community is also subject to dramatic seasonal changes, and information on these community structures in the winter compared to spring and fall is sorely needed. Also, most studies so far have focused on annual ice or fast ice while the significance of biological communities in multiyear ice—the majority of the sea ice present in the Arctic—is unknown. One way of combining multiyear ice studies with seasonal investi- gations is the establishment of permanent ice floe stations that can be revisited at intervals until 2010. It was proposed to establish ice stations in the Transpolar Drift and in the Beaufort Gyre. Within the plankton, the major gaps in knowledge are delicate groups such as the gelatinous plankton, and nektonic groups such as cephalopods that are either destroyed or escape the traditional net sampling. Although copepods are reasonably well studied, knowledge on several small species is lacking for a comprehensive biodiversity understanding. Among the phytoplankton, morphological and physiological characteristics may vary within a species. A 2 Recommendations better understanding of species composition will improve our understanding of their ecology and physiology as well as interactions and processes in the ecosystem. A combination of microscope and molecular techniques were suggested to help eliminate ambiguities. For benthic communities, patterns of floral and faunal biodiversity in the Arctic Ocean need to be related to hydrological processes and primary production to predict effects of climate change. Most efforts have traditionally been invested in shallow water benthic systems on the continental shelves. The Chukchi, Bering, Laptev, and Kara shelves have been most studied, while the Eastern Siberian Shelf is still comparatively under-explored. The extent to which infauna and epibenthic megafauna have been studied so far varies among the different shelf regions, but common to all areas, meiofaunal communities including Foraminifera are the most unknown. Also, among the coastal regions, the fjord systems of the Canadian Archipelago and of Greenland are among the least well known. The shelf breaks and the deep-sea basins of the Arctic Ocean are not well studied, with the deep Canada Basin being the least known of all. Since the Canada Basin is a long-time separated system with little exchange to other deep-sea basins, this will be a particularly interesting area to
