Leaf compressions, spores, and pollen grains referrable to about 45 species were collected from a series of fine silts and coal stringers in the Parsnip River valley of the Rocky Mountain Trench. The leaf assemblage described in this paper indicates a late Maestrichtian to Danian age, somewhat younger than generally comparable assemblages previously reported from the lower part of the Edmonton Formation of Alberta, and from the Hell Creek, Lance, and Fox Hills Formations in the western interior of the United States. It also contains several species reported from the Nanaimo Group on eastern Vancouver Island. Plant microfossils (to be described in a later paper) include species of Glyptostrobus, Sciadopitys, Aquilapollenites, Pistillipollenites, Alnus, Myrica, Tilia, Pterocarya, and Carya, together with tricolpate pollen of uncertain affiliation. The combined leaf and microfossil assemblages indicate a warm mesothermal and humid paleoecological setting of low relief, suggesting absence of major mountain ranges westward to the Pacific Ocean.

The report by Titian Ramsay Peale on birds encountered during the Wilkes Expedition was withdrawn for inaccuracy when few copies had been distributed, and re-written by John Cassin. A survey of the accounts of the petrels shows that this was not an improvement. Two important type localities for Procellaria brevipes and Thalassidroma lineata are probably wrong, and could be exchanged.

This chapter takes a broad look at the Pacific Ocean in relation to Chinese migration. As trade, consumption and capital flows followed migrants, powerful networks were woven and sustained; in time, the networks fanned across the Pacific from British Columbia along the West Coast of the United States to New Zealand and Australia. The overlapping personal, family, financial and commercial interests of Chinese in California and those in Hong Kong, which provide the focus of this study, energized the connections and kept the Pacific busy and dynamic while shaping the development of regions far beyond its shores. The ocean turned into a highway for Chinese seeking Gold Mountain, marking a new era in the history of South China, California, and the Pacific Ocean itself.

The late Professor Edward Bourne, of Yale, used to say that the Philippine Islands were attached to the Spanish West Indies till after 1823, and therefore it ought to be presumed that Monroe intended his doctrine to apply to that Asiatic archipelago. The quip leads the mind to the important fact that the relations of the Pacific Coast of America, the Pacific Ocean, and the nations of Asia, are all bound together. The first Asiatic trade went from Philadelphia, Boston, Providence, and other Atlantic ports via the Northwest Coast to China. The relation of the original Monroe Doctrine to Oregon is familiar to all students of the Monroe Doctrine. It is curious that the objection to “colonization” which was intended to block the way of Russia, has been applied almost entirely to the West Indies and the eastern coast of North and South America. The clause in Monroe’s declaration had little to do with the process by which the United States came to have a Pacific front.

Examination of a small collection of Oniscidea from Costa Rica revealed the presence of two species new to science (Ischioscia martinae sp.nov. and Scleropactes talamancensis sp.nov.). Further specimens from the collection of the United States National Museum were reexamined to reconsider the status of Philoscia muscorum (Scopoli, 1793) and Ischioscia variegata (Dollfus, 1893), both of which have been reported from Costa Rica. The specimens belong to two new species (Ischioscia muelleri sp.nov. and Ischioscia elongata sp.nov.). Redescriptions of Ligia baudiniana Milne Edwards, 1840 from the shores of both the Caribbean Sea and the Pacific Ocean and the type material of Ischioscia variegata (Dollfus, 1893) from Venezuela are also presented.

Abstract This study analyzes 25 years of Special Sensor Microwave Imager (SSM/I) retrievals of rain rate and wind speed to assess changes in storminess over the open water of the Pacific Ocean. Changes in storminess are characterized by combining trends in both the statistically derived 95th percentile exceedance frequencies of rain rate and wind speed (i.e., extremes). Storminess is computed annually and seasonally, with further partitioning done by phase of the El Niño–Southern Oscillation (ENSO) index and the Pacific decadal oscillation (PDO) index. Overall, rain-rate exceedance frequencies of 6–8 mm h−1 cover most of the western and central tropical Pacific, with higher values present around the Philippines, Japan, Mexico, and the northwest coast of Australia. Wind speed exceedance frequencies are a strong function of latitude, with values less (greater) than 12 m s−1 equatorward (poleward) of 30°N/S. Statistically significant increasing trends in rain rate were found in the western tropical Pacific near the Caroline Islands and the Solomon Islands, and in the extratropics from the Aleutian Islands down the coast along British Columbia and Washington State. Statistically significant increasing trends in wind speed are present in the equatorial central Pacific near Kiribati and the Republic of the Marshall Islands (RMI), and in the extratropics along the west coast of the United States and Canada. Thus, while extreme rain and winds are both increasing across large areas of the Pacific, these areas are modulated according to the phase of ENSO and the PDO, and their intersection takes aim at specific locations.

The personnel of the Supreme Court remained unchanged during the 1959 Term. From the point of view of the decisions rendered in the public law field, this was an undistinguished Term. Few of the constitutional cases are likely to hold an important place among the precedents, and a considerable number of well-argued decisions turned entirely upon private law questions. But there was no dearth of writing, during the period under review, about the Court as an institution and about the Justices who sit there.Note may be made at this point of the latest chapter in the long dispute over the so-called tidelands. In 1947 the Supreme Court had ruled that, as against the claims of California, the United States possessed paramount rights in lands underlying the Pacific Ocean seaward from the low-water mark. Similar rulings were made in 1950 as regards the claims of Louisiana and Texas in the Gulf of Mexico. But with the enactment in 1953 of the Submerged Lands Act, the United States relinquished to the coastal states all of its rights in all lands beneath navigable waters within the three-mile limit, and in excess of that limit within state boundaries as they existed at the time a state became a member of the Union, or as theretofore approved by Congress. The limit of the grant was three leagues (about ten and one-half miles) in the Gulf of Mexico and three geographical miles in the Atlantic and Pacific. The actual extent of the claims of the coastal states involved in the question was therefore left to be settled by litigation.

Of the nine countries known to have nuclear weapons, six are located in Asia and another, the United States, borders the Pacific Ocean. Russia and China were the first Asian nations with nuclear weapons, followed by Israel, India, Pakistan, and North Korea. Most of the world's nuclear powers are reducing their arsenals or maintaining them at historic levels, but several of those in Asia—India, Pakistan, and North Korea—continue to pursue relentless and expensive programs of nuclear weapons development and production. Hopefully, the nuclear agreement reached in July 2015 between Iran, the European Union, and the five permanent members of the United Nations Security Council will be a step toward eliminating nuclear weapons throughout Asia and the rest of the world. As we will discuss below, any country possessing a nuclear arsenal is on a path leading toward self-assured destruction, and is a threat to people everywhere on Earth.

Abstract Ipomoea quamoclit is a fast-growing vine, native to Mexico and Central America, and widely cultivated and introduced to many countries as an ornamental for its attractive foliage and bright flowers. It has escaped from cultivation to become naturalized and invasive in a variety of habitats, where it competes with native vine species and behaves as an agricultural weed. It is listed as invasive in Australia, Papua New Guinea, India, the United States, Brazil, the Galapagos Islands, Costa Rica, Cuba, the Maldives, the Seychelles and many islands in the Pacific Ocean.

The article is devoted to the problem of formation of approaches and assessments of the Chinese crisis of 1931 in the US press; it is based on the materials of both Democratic and Republican press of the USA. The materials of the American press of 1931 dedicated to the search for the most efficient optimal strategy of building relations with China and Japan demonstrate a steady interest of American mass media towards negative and positive experience of Asianpolicy. In the course of a difficult search of an optimal view on crisis, several polar points of view were formulated in the American press. A study of daily newspapers and analytical magazines in the United States shows that in the fall of 1931 two approaches to the «Chinese incident» were formed: isolationist and internationalist. In the fall of 1931, the US periodicals did not yet have the idea of “saving China”, which became popular during the second Sino-Japanese war. The journalists and editors viewed a tacit and indirect support for the Japanese claims as only significant model for solving the «China problem». Thus, the study of the positions of the major American press and the most prominent journalists is important for understanding how the USA, after the Chinese crisis, gradually realized its place in the new system of international relations. In addition, the press shows how the United States planned to develop interaction with the warring states in the Pacific Ocean.
