Abstract:
... The October 17th, 2015 Taan Fiord landslide and tsunami generated a runup of 193 m, nearly an order of magnitude greater than most previously surveyed tsunamis. To date, most post-tsunami surveys are from earthquake-generated tsunamis and the geomorphic signatures of landslide tsunamis or their potential for preservation are largely uncharacterized. Additionally, clear modifications described duri ...

Abstract:
... The 33 km-long Ragged Mountain fault (RMF) forms the northwestern corner of the Yakutat Terrane, which is colliding with the North American plate in south coastal Alaska at ∼5.5cm/yr. The fault zone contains three types of scarps in a zone up to 175m wide: (1) antislope scarps on the lower range front, (2) a sinuous thrust scarp at the toe of the range front, and (3) a swarm of flexural-slip scarp ...

Abstract:
... The Pacific Sand Lance (Ammodytes personatus) is a major component of the forage base for many species of marine birds, mammals, and fishes. Despite its ecological importance, relatively little is known regarding basic biology or life-history parameters for this species. Information on age and growth is particularly lacking for Pacific Sand Lance in the Salish Sea, an inland sea that encompasses t ...

Abstract:
... Fluctuating asymmetry is the non-directional deviations from bilateral symmetry and occurs across organisms. Fish otoliths are often used to test for differences in symmetry as otoliths aid in hearing, homing, and balance. Here, we evaluated the symmetry of otolith pairs in adult Chinook Salmon between wild and hatchery-origin stocks. Pacific salmon are economically and ecologically important to t ...

These echo signals were analyzed for characteristic patterns of krill diel vertical migration (DVM) from which daily and seasonally-averaged DVM ...

Abstract:
... The Arctic is subject to long-range atmospheric deposition of globally-distilled semi-volatile organic compounds (SVOCs) that bioaccumulate and biomagnify in lipid-rich food webs. In addition, locally contaminated sites may also contribute SVOCs to the arctic environment. Specifically, Alaska has hundreds of formerly used defense (FUD) sites, many of which are co-located with Alaska Native village ...

In Alaska, while introduction of 13-valent pneumococcal conjugate vaccine led to declines in invasive pneumococcal disease, carriage prevalence remained stable because of replacement with non-vaccine serotypes. We assessed antibiotic non-susceptibility of carried pneumococci during serotype redistribution, determined the contributions of within-serotype shifts, and assessed factors that could expl ...

Analyses of marine palynomorphs, including dinocysts and acritarchs, from Pliocene-Pleistocene sediments of the Ocean Drilling Program (ODP) Site 887 in the Gulf of Alaska allowed the development of a biostratigraphic scheme, which we compared with bio-events in regional diatom and radiolarian zonations. The dinocyst biostratigraphic scheme includes five biozones and four major boundaries. A first ...

The misidentification of biomimetic or biomorphic structures (especially helical forms) as biogenic can lead to serious errors in the interpretation of depositional environments and stratigraphic relationships, and in the detection of primitive life. “Dinocochlea ingens” was originally described as a giant gastropod and recently has been interpreted as a diagenetically-modified ichnofossil, based ...

It is distinctive due to its lirellate apothecia, the (mainly) discrete soralia, the production of roccellic/angardianic acid, and its habitat on coastal rocks in the salt spray zone. A key to sorediate species of Opegrapha is provided. ...
