“…A land bridge between Alaska and Siberia was re‐established later in the Early Pliocene, between 4.4 and 3.6 Mya, but the strait opened again in the mid‐Pliocene, 3.6 to 3.25 Mya. After closing again, the strait once again connected the Pacific with the Arctic Ocean beginning approximately 2 Mya during the Early Pleistocene (Gladenkov, Barinov, Basilyan, & Cronin, ; Gladenkov & Gladenkov, ; Marincovich, ; Titova, ). The strait closed intermittently during glacial stages of the Pleistocene.…”

Aims Some biogeographical regions act primarily as donors of colonists to other regions, while others act predominantly as recipient areas. How some biotas become dominant while others do not is a largely historical question that has received surprisingly little attention from biogeographers. Here, we seek to answer this question for the cold‐water North Pacific biota, which did not exist forty million years ago but which is now the principal donor biota outside the tropics. Location We focus on the cool‐temperate coastal North Pacific Ocean over the last 36.5 million years. Taxon We consider all multicellular taxa for which adequate fossil, phylogenetic and biogeographical data exist. Methods After placing North Pacific geographical events in the broader context of ocean gateways opening and closing elsewhere in the world, we discuss the history and factors affecting the planktonic and benthic productivity in the North Pacific based on a review and critical evaluation of the literature. A synthesis of primary sources was used to evaluate the origins and fates of North Pacific lineages, with special emphasis on movements to, within and from the North Pacific during the Cenozoic era. Results During the Late Eocene to earliest Miocene, the cooling North Pacific received colonists from adjacent warm‐water regions and the cold Southern Hemisphere, where temperate conditions had existed since at least the Cretaceous. From the Miocene onward, the North Pacific biota began to spread to the Southern Hemisphere and through Bering Strait to the Arctic and North Atlantic Oceans. Within the North Pacific, lineages during the early cooling phases spread predominantly from west to east, but in the Early Middle Miocene this pattern reversed, with later expansions going in both directions. An increase in productivity, powered by the evolution of highly productive seaweeds and by consumers with high metabolic rates, accompanied the transformation of the North Pacific from a recipient to donor biota. Main conclusions The North Pacific replaced the Southern Hemisphere temperate biota as the principal donor biota during the Miocene through a combination of increasing productivity, low magnitudes of extinction and intense competition and predation in an ocean basin with a long coastline.

“…Kennett (1982 went so far as to implicate the nearly simultaneous emergence of the Isthmus of Panama and submergence of the Bering Strait as critical elements in Pliocene cooling of the Northern Hemisphere. This view persisted for more than a decade until Gladenkov et al (1991) presented new evidence from Karaginsky Island o! the Kamchatka Peninsula for the arrival of Atlantic mollusk endemics as early as 4.0}4.2 My, based on diatom biostratigraphy and "ssion-track ages.…”

Aspects of the paleogeography, stratigraphy, and glacial history of Beringia have been greatly revised over the past 15}20 yr. Access to North East Russia, in particular, has provided the opportunity to evaluate the Beringia landscape as a contiguous subcontinent during the Quaternary. For the "rst time, new research has made clearer the connection between tectonic forces and the submergence of the Bering Strait during the middle Pliocene. Revisions in the regional stratigraphy of glacial and interglacial deposits in northwest Alaska and northeast Russia provide a new foundation for assessing the causes for di!erences in glacial ice extent through time. The consensus of all "eld workers veri"es that glacial ice throughout most of Beringia was of very limited extent during the last glacial maximum. The onset of regional glaciation during the waning stages of the last interglaciation is clearly out of phase with glaciation at lower latitudes. Despite the lack of much glacial activity during the early Holocene, Alaska contains a rich record of late Holocene glacial response to Neoglacial cooling. Changes in the Holocene environment of Beringia likely had a profound a!ect on early inhabitants. The curiosity-driven vision and spirit of both David Hopkins and the late Troy Pewe have had a profound in#uence on Arctic paleoenvironmental research.

“…The supply of terrigenous material increased markedly at times of known climate change in the middle Miocene and late Pliocene and thus may be related to the enhanced physical erosion of the North Pacific rim caused by deterioration of climate in those regions. Work in eastern Kamchatka by Gladenkov and Shantser (1989) and Gladenkov et al (1991) rate of plate convergence in the region in Eocene time (Rea and Duncan, 1986), the deep passage is at the western end of the Aleutian chain, the Kamchatka Strait. At present the dominant transform plate boundary at the western end of the Aleutian Trench lies along the northern side of the Aleutian Ridge, so the Kommandorski Islands (Fig.…”

Ocean Drilling Program Leg 145 crossed the North Pacific Ocean from Japan to Canada in the summer of 1992, the first deep ocean drilling in the Subarctic Pacific since the 1971 cruises of Deep Sea Drilling Project Legs 18 and 19. All of the Cenozoic paleoceanographic objectives of the cruise were accomplished. We determined the history of silica deposition in the North Pacific and resolved the timing of the late Miocene "silica switch" when the locus of silica deposition changed from the North Atlantic to the North Pacific. A depth transect drilled on the flanks of Detroit Seamount in the far northwestern Pacific allowed the reconstruction of the calcite compensation depth for the North Pacific over the past 70 Ma. The Meiji sediment tongue was shown to be a drift deposit, identical in nature to those better known from the North Atlantic. The Meiji Drift contains northern-source diatoms and minerals from the Bering Sea region and has been accumulating since the early Oligocene. This means that southward-flowing bottom water has been exiting the Bering Sea to the North Pacific basin for the past 35 million years. Presently, water exits the Bering Sea at the same rate, 10 to 20 Sv (1 Sv = I0 6 m 3 /s), as North Atlantic Deep Water leaves the northwesternmost Atlantic. Late Cenozoic cooling was determined to have been underway by the end of Miocene time when ice-rafted debris first occurs at the Leg 145 drill sites. A middle Pliocene warm interval interrupted the high-latitude cooling for about a million years. Large-scale Northern Hemisphere glaciation is shown to have begun rather abruptly at 2.6 Ma by a rapid increase in the delivery of terrigenous hemipelagic and ice-rafted debris sediment to the North Pacific. At this same time abyssal circulation begins to modify sediment depositional patterns in the northwestern Pacific deep basin. The sequence of ash layers recovered downwind from both the Kamchatka Peninsula (the world's most active Pliocene-Pleistocene volcanic field) and the Aleutian arc allows the geochemical evolution of these volcanic centers to be determined. An order of magnitude increase in the number and thickness of ash layers occurred at 2.6 Ma. High-resolution studies of the past 4.0 Ma show that biogenic sediment fluxes are generally higher during interglacial periods. This observation indicates that more rapidly circulating deep ocean waters during interglacial episodes is the dominant source of nutrients to the Subarctic Pacific rather than those supplied by regional runoff or dust input.
