Exploitation of ringed seals (<i>Phoca hispida</i>) in Greenland
Authors: Teilmann Jonas , Kapel Finn O 
Published: July 2014

The ringed seal (Phoca hispida) is the most important game for the Inuit hunters of Greenland, providing many of the basic needs in the original culture. It is distributed all around Greenland with the main distribution north of 69°N on the west coast and north of 66°N on the east coast. During 1974-76, studies were conducted in the most important ringed seal catching area, Upernavik, Northwest Greenland, and a total of 7,089 ringed seals were sampled. The methods used for catching ringed seals were categorised into five different groups. The most common hunting method used in the municipality of Upernavik during 1974-76 was netting under the ice, accounting for almost half of the total annual catch. Seals shot on the ice and seals shot at the ice edge accounted for one fifth and one tenth of the annual catch, respectively. In this region seals shot in open water made up about one fifth of the annual catch of ringed seals, while netting in open water contributed only a few percent.Of the seals sampled in Upernavik in 1974-76, 60% were males and 40% were females. In the ringed seal samples collected all around Greenland in the 1980s and 1990s the males comprised 56% and the females 44% (n=923). Similar ratios were found for all age classes and for all hunting methods suggesting either a skewed sex ratio in the ringed seal stock(s) around Greenland or a differencein availability to the hunters of male and female ringed seals. In tagging experiments a higher mobility was found for females than for males, which suggests differences in the behaviour of the two sexes.Catch and trade statistics on ringed seals are reviewed and evaluated for the period of 1954 until 1994, and the seasonal and regional variation is examined. The peak season for ringed seal hunting in Greenland as a whole is from January through May. This is particularly evident for the northern regions, where relatively few ringed seals are taken during the open water season from June to September. In the southern regions, however, the great majority of ringed seals are caught in openwater.In all regions, the catch of ringed seals showed great annual and long-term variation. The variations were not identical in all regions, but similar trends were found for Northwest and Central West, and for Southwest and South. From 1954 to 1994 there was a general, significant increase in the reported catches of ringed seals in west Greenland. For Greenland overall, the catch of ringed seals wasaround 43,000 per year in the 1950s, peaked in the late 1970s at almost 100,000 per year, but since decreased to about 70,000 in the early 1990s.

Published: July 2014

Seven studies of netting and tagging of ringed seals (Phoca hispida) in Greenland 1976-1997 are described. The areas of operation were: northern part of the Upernavik area (Northwest Greenland), Kong Oscars Fjord (Northeast Greenland), and Avanersuaq (Thule, North Greenland). Altogether, 135 seals were caught, of which 99 were tagged and released with Dalton Jumbo rototags. Recapture of 38 tagged seals has been reported to date. The recaptures demonstrate movements of ringed seals in Greenland of more than 100km within districts, as well as long-distance movementsof more than 1000km from the site of release.
Evidence of an upper mantle seismic anomaly opposing theCocos slab beneath theIsthmus ofTehuantepec,Mexico
Authors: Kim YoungHee , Lim Hobin , Miller Meghan S. , Pearce Fred , Clayton Robert W. 
Published: July 2014

AbstractSubduction of the Cocos plate beneath southern Mexico is characterized by several unusual features, such as a discontinuous volcanic arc, unusual arc chemistry, and anomalously low topography of Tehuantepec Isthmus. Recent seismic images from both receiver functions and seismic tomography suggest that there may be an additional, opposing structure dipping to the southwest from the Gulf of Mexico, and these images have been previously explained by a southwest‐dipping slab. However, standard models of the Caribbean tectonic history do not support this interpretation. To better define the Cocos slab's structure and the possible existence of a structure dipping in the opposite direction, dense seismic data across southern Mexico are used to form high‐resolution seismic images, based on the 2‐D generalized radon transform method, and to relocate regional earthquakes. Our images show the Cocos plate dipping at 30° to the northeast encounters the anomaly that is dipping in the opposite sense at ∼150 km depth. Relocated seismicity clearly delineates a Wadati‐Benioff zone that marks the subducting Cocos plate. A cluster of seismicity also appears at ∼150 km depth which may be related to the subduction of the Tehuantepec ridge and/or to the imaged seismic structure with opposite polarity.
A model for knickpoint migration in first‐ and second‐order streams
Authors: Bressan Filippo , Papanicolaou A. N. , Abban Benjamin 
Published: July 2014

AbstractWe introduce a new theoretical framework for knickpoint migration in unventilated flows prevalent in channelized semicohesive first‐ and second‐order streams characterized by a sequence of constrictions and expansions in the channel cross section. A key feature of the framework is the inclusion of shear‐induced fluvial erosion due to flow suction at the nappe as the key mechanism driving migration. Channel surveys, water stage, time‐lapse photography, and laser scans from Mud Creek, Iowa, USA, confirm this unventilated erosive mechanism and reveal a dual advective‐diffusive mode of retreat. We treat the fluvial bed shear stress as being similar to the flow on the lee side of a submerged obstacle and derive a governing equation which is a generalized Burgers' equation. The equation is solved to successfully simulate knickpoints monitored in two sites (Iowa and Mississippi), and a modified Peclet number is used to analyze the advective‐diffusive nature of the knickpoint migration.
Sea level extremes in the Caribbean Sea
Authors: Torres R. Ricardo , Tsimplis Michael N. 
Published: July 2014

AbstractSea level extremes in the Caribbean Sea are analyzed on the basis of hourly records from 13 tide gauges. The largest sea level extreme observed is 83 cm at Port Spain. The largest nontidal residual in the records is 76 cm, forced by a category 5 hurricane. Storm surges in the Caribbean are primarily caused by tropical storms and stationary cold fronts intruding the basin. However, the seasonal signal and mesoscale eddies also contribute to the creation of extremes. The five stations that have more than 20 years of data show significant trends in the extremes suggesting that flooding events are expected to become more frequent in the future. The observed trends in extremes are caused by mean sea level rise. There is no evidence of secular changes in the storm activity. Sea level return periods have also been estimated. In the south Colombian Basin, where large hurricane‐induced surges are rare, stable estimates can be obtained with 30 years of data or more. For the north of the basin, where large hurricane‐induced surges are more frequent, at least 40 years of data are required. This suggests that the present data set is not sufficiently long for robust estimates of return periods. ENSO variability correlates with the nontidal extremes, indicating a reduction of the storm activity during positive ENSO events. The period with the highest extremes is around October, when the various sea level contributors' maxima coincide.
High‐Rate Oxygen Electroreduction over Graphitic‐N Species Exposed on 3D Hierarchically Porous Nitrogen‐Doped Carbons
Authors: He Wenhui , Jiang Chunhuan , Wang Jiabo , Lu Lehui 
Published: July 2014

AbstractNitrogen‐doped species (NDs) are theoretically accepted as a determinant of the catalytic activity of metal‐free N‐doped carbon (NC) catalysts for oxygen reduction reaction (ORR). However, direct relationships between ND type and ORR activity have been difficult to extract because the complexity of carbon matrix impairs efforts to expose specific NDs. Herein, we demonstrate the fabrication of a 3D hierarchically porous NC catalyst with micro‐, meso‐, and macroporosity in one structure, in which sufficient exposure and availability of inner‐pore catalytic sites can be achieved due to its super‐high surface area (2191 cm2 g−1) and interconnected pore system. More importantly, in‐situ formation of graphitic‐N species (GNs) on the surface of NC stimulated by KOH activation enables us to experimentally reveal the catalytic nature of GNs for ORR, which is of great significance for the design and development of advanced metal‐free NC electrocatalysts.
π‐Extended DPCB for Activation‐Free Homogeneous Gold Catalysis

Published: July 2014

AbstractThe catalytic properties of bis[chlorogold(I)] complexes that bear the 3,4‐bis(2,4,6‐tri‐tert‐butylphenyl)‐3,4‐diphosphinidenecyclobutene (DPCB) ligand could be improved by suitable extension of the π‐conjugation. If the 1‐naphthyl substituent was employed in the 1,2‐positions in the kinetically stabilized DPCB skeleton, high catalytic activity of the DPCB‐bis(chlorogold) complex was induced in the intermolecular alkoxycyclization of 1,6‐enyne without activation by a Ag cocatalyst. DFT calculations of the 1,2‐diaryl‐substituted DPCB derivatives indicated that both suitable energetic reduction of the LUMO level and steric characteristics of the ligand structure are important for the high catalytic activity. The optimized 1‐naphthyl‐substituted DPCB‐chlorogold(I) complex was further employed for catalytic intramolecular cyclizations to afford heterocyclic structures by the activation of terminal acetylene and allene moieties and the hydration of terminal acetylene under the mild conditions.
Operando X‐ray Absorption Spectroscopy Studies of Sintering for Supported Copper Catalysts during Liquid‐phase Reaction
Authors: O'Neill Brandon J. , Miller Jeffrey T. , Dietrich Paul J. , Sollberger Fred G. , Ribeiro Fabio H. , Dumesic James A. 
Published: July 2014

AbstractOperando X‐ray absorption spectroscopy is used to measure simultaneous changes in catalyst structure and changes in catalytic activity versus time during the liquid phase hydrogenation of furfural over supported copper catalysts. This approach allows the size of the copper nanoparticles to be monitored continuously versus time‐on‐stream, such that these changes in dispersion can be accounted for in the calculation of turnover frequency. It is shown that sintering of the copper nanoparticles is the predominant mode of catalyst deactivation for a Cu/γ‐Al2O3 catalyst throughout its time‐on‐stream, leading to irreversible loss of catalytic activity. In contrast, this mode of deactivation is eliminated by atomic layer deposition of an alumina overcoat; however, deposition of carbonaceous deposits in the small pores of the overcoat leads to deactivation that is reversible upon calcination of the catalyst.
