    Abstract
    Radiocarbon has been an important constituent of radioactive wastes dumped in the open ocean and marginal seas as well as wastes released from nuclear reprocessing plants. Therefore, in some regions these sources could have a greater impact on 14C concentration in seawater than global fallout. The high analytical sensitivity of 14C measurement by accelerator mass spectrometry (AMS) allows even tracer amounts of 14C to be found in seawater at radioactive waste dumping sites and their comparison with the global distribution of this radionuclide. Data on measurements of 14C in samples taken at former dumping sites in the northeast Atlantic and northwest Pacific Oceans and in the open ocean are discussed and compared with other anthropogenic radionuclides, namely 3H. Small increases in 14C concentrations observed in some bottom and surface seawater samples collected at the Northwest Pacific Ocean dumping sites require further 14C analyses before final conclusions can be made on possible leakages from dumped radioactive wastes.

      Drivers for genetic structure at different geographic scales for Pacific red snapper (Lutjanus peru) and yellow snapper (Lutjanus argentiventris) in the tropical eastern Pacific

      Reguera‐Rouzaud, Nicole; Díaz‐Viloria, Noé; Pérez‐Enríquez, Ricardo; Espino‐Barr, Elaine; Rivera‐Lucero, Mailin Isabel; Munguía‐Vega, Adrián; Conservation Genetics Laboratory & Desert Laboratory on Tumamoc Hill, University of Arizona (Blackwell Publishing Ltd, 2020-12-22)
      The tropical eastern Pacific (TEP) is a highly dynamic region and a model system to study how habitat discontinuities affect the distribution of shorefishes, particularly for species that display ontogenetic habitat shifts, including snappers (Lutjanidae). To evaluate the genetic structure of the Pacific red snapper (Lutjanus peru) and the yellow snapper (Lutjanus argentiventris) throughout their distribution range along the TEP, 13 and 11 microsatellite loci were analysed, respectively. The genetic diversity of L. peru (N = 446) and L. argentiventris (N = 170) was evaluated in 10 and 5 localities, respectively, showing slightly higher but non-significant values in the Gulf of California for both species. The genetic structure analysis identified the presence of significant genetic structure in both species, but the locations of the identified barriers for the gene flow differed between species. The principal driver for the genetic structure at large scales >2500 km was isolation by distance. At smaller scales (<250 km), the habitat discontinuity for juveniles and adults and the environmental differences throughout the distribution range represented potential barriers to gene flow between populations for both species. © 2020 Fisheries Society of the British Isles

      Measurements of I-129 in the Pacific Ocean at Scripps Pier and Pacific Northwest sites: A search for effects from the 2011 Fukushima Daiichi Nuclear Power Plant accident and Hanford

      Chang, Ching-Chih; Burr, George S; Jull, A J Timothy; Russell, Joellen; Priyadarshi, Antra; Lin, Mang; Thiemens, Mark; Biddulph, Dana; Univ Arizona, AMS Lab; Univ Arizona, Dept Geosci (ELSEVIER, 2019-11-01)
      Radionuclides from the Fukushima Daiichi Nuclear Power Plant were released directly into the ocean as a result of the Great East Japan Earthquake on March 11, 2011. This material became entrained in surface ocean currents and subsequently transported for great distances. In June 2011, a few months after the disaster, we began a surface ocean 129I monitoring program, with samples from Scripps Pier, La Jolla, California, USA, with the expectation that surface currents originating off the east coast of Japan would eventually carry radionuclides to the La Jolla site. After 7 years of ocean transport, a distinct signal has not yet arrived at Scripps Pier. We have however, recorded an interesting systematic seasonal 129I time series record that stems from surface circulation variations along the California coast. To provide a more comprehensive picture of the 129I budget in coastal surface waters off the west coast of the U.S., we also include 129I data from the Columbia River, and offshore sites along the coast of Washington State. Anthropogenic nuclides are carried by the Columbia River into the Pacific Ocean from the vicinity of the decommissioned Hanford nuclear facility. We find highly elevated 129I/127I values in the Columbia River, downstream from the Hanford site, but this anthropogenic 129I becomes significantly diluted once it reaches the Pacific Ocean. Nonetheless, its imprint persists in surface seawater off the west coast of the U.S. that has significantly higher 129I/127I levels than other surface sites in the Pacific Ocean.

      Pacific Yup'ik: Implications for Metrical Theory

      Rice, Curtis; Myers, James; Pérez, Patricia E.; University of Texas, Austin (Department of Linguistics, University of Arizona (Tucson, AZ), 1990)
      Recent developments in metrical theory have led to the situation in which there are now at least four different approaches to stress assignment. One approach uses only a grid to represent the relative prominence of syllables in a word (cf. Prince 1983); aside from representational conventions, the grid -only approach differs from the other three in that it does not posit any metrical constituency. Second, the constituentized grid approach also represents stress with a grid, but by enhancing the representations with parentheses, metrical constituency is also indicated (cf. Halle and Vergnaud 1987). Hayes (1987) has recently developed an approach employing representations like those in the constituentized grid approach; I will refer to this as the templatic approach. This approach is different insofar as the constituents which are available in the theory are not derived from parameters, but rather it is the constituent templates themselves which are the primitives of the theory. The fourth approach is one in which relative prominence is indicated with arboreal structures, rather than with grids (cf. Hayes 1981, Hammond 1984). In this paper I will present an analysis of the stress pattern of Pacific Yup'ik which follows Rice (1988), and I will claim that this analysis has important implications for each of the approaches mentioned above. Pacific Yup'ik is a particularly interesting testing ground for metrical theories; for our purposes here, the interesting aspect is that an adequate analysis of the stress pattern has broad implications for various approaches to stress assignment.
