| Abstract |
Environmental contaminants are found throughout Arctic marine ecosystems, and their presence in seabirds has been associated with toxicological responses. However, there are few studies of genotoxicity in Arctic avian wildlife. The purpose of the present study was to quantify deoxyribonucleic acid (DNA) damage in lymphocytes of selected seabird species and to examine whether accumulation of organohalogen contaminants (?OHCs) affects DNA damage. Blood was sampled from common eider (Somateria mollissima), black guillemot (Cepphus grylle), black?legged kittiwake (Rissa tridactyla), glaucous gull (Larus hyperboreus), arctic skua (Stercorarius parasiticus), and great skua (Stercorarius skua) in Kongsfjorden, Svalbard (Norway). Contaminant concentrations found in the 6 species differed, presumably because of foraging ecology and biomagnification. Despite large differences in contaminant concentrations, ranging from ?OHCs 3.3?ng/g wet weight in the common eider to ?OHCs 895?ng/g wet weight in the great skua, there was no strong difference among the species in baseline DNA damage or sensitivity to a genotoxic stressor (hydrogen peroxide). Baseline levels of DNA damage were low, with median values ranging from 1.7% in the common eider to 8.6% in the great skua. There were no associations between DNA damage and contaminants in the investigated species, suggesting that contaminant concentrations in Kongsfjorden are too low to evoke genotoxic effects, or possibly that lymphocytes are resistant to strand breakage. Clearly, genotoxicity is a topic for future studies of Arctic seabirds. Environ Toxicol Chem 2018;37:1084?1091. ? 2017 SETAC |

anisotropy density liquid outer core seismic wave speeds seismological properties solid inner core |
| Abstract |
Summary The seismologically observed structures of both the solid inner core and the liquid outer core are the ground truth for the material properties of solid and liquid iron and its alloying elements. The key properties, from a materials science standpoint, are density, seismic wave speeds, and anisotropy. The anisotropy of the inner core does not appear to be simple; it varies laterally at the same radial level as well as varying radially. Four themes including uncertainty, model variability, virtues of solid vs. liquid properties, and composition, are the focus of this chapter. Their elaboration hopefully help present and future investigators of the physical state and composition of the core understand the problems associated with certain types of data and to focus experimental work on avenues of research providing tight observational constraints on the core's character. |

correlation earthquake New Zealand rupture seismology slip inversion |
| Abstract |
Abstract We investigate the Mw 7.8, 2016 Kaikoura (New Zealand) earthquake by using optical satellite imagery and seismology to reveal the main features of the rupture process. Correlation of Landsat8 images reveals a 30?40?km surface rupture on the Kekerengu Fault and Jordan Thrust, with up to 12?m of right?lateral slip. A previously unrecognized conjugate strike?slip fault, the Papatea Fault, also slipped coseismically (3?4?m). The global centroid moment tensor (gCMT) centroid indicates both thrust and right?lateral slip and is located ~100?km NE of the main shock epicenter. The significant non?double?couple component of the gCMT (25%) suggests that the main shock is not well represented by a single planar fault. Back projection of teleseismic P waves reveals two main bursts of seismic radiation: (1) at 10?20?s, near the main shock epicenter, and (2) at ~70?s, close to the observed surface ruptures. We determine a finite source kinematic model of the rupture from the inversion of seismic waveforms. We use two faults in our model, defined to match the observed slip on the Kekerengu Fault, and a deeper offshore fault with a lower dip angle to satisfy the long period seismological observations. We compute the equivalent moment tensor from our finite source model and find it to be remarkably consistent with the gCMT solution. Although little is known about the geometry of these faults at depth, if the Kekerengu Fault splays from the deeper thrust, then it provides a rare example where the contribution of slip on a splay fault can be clearly isolated in the seismological waveforms. |

albedo neutron cosmic ray spectrometer |
| Abstract |
Abstract This paper investigates seasonal cosmic ray?induced neutron variations measured over a long?term period (from 2011 to 2016) in both the high?altitude stations located in medium geomagnetic latitude and Antarctica (Pic?du?Midi and Concordia, respectively). To reinforce analysis, modeling based on ground albedo neutrons simulations of extensive air showers and the solar modulation potential was performed. Because the local environment is well known and stable over time in Antarctica, data were used to validate the modeling approach. A modeled scene representative to the Pic?du?Midi was simulated with GEANT4 for various hydrogen properties (composition, density, and wet level) and snow thickness. The orders of magnitudes of calculated thermal fluence rates are consistent with measurements obtained during summers and winters. These variations are dominant in the thermal domain (i.e., En??20?MeV) is weakly impacted. The role of hydrogen content on ground albedo neutron generation was investigated with GEANT4 simulations. These investigations focused to mountain environment; nevertheless, they demonstrate the complexity of the local influences on neutron fluence rates. |
