Adsorption of dissolved phosphate onto iron-hydroxides has been shown to be one of the primary regulators of phosphorus cycling in sediments. Bioturbation and bioirrigation by benthic infauna modify this cycling by accelerating the transport of dissolved and particulate phosphorus and by changing rates of reactions that occur in the sediment, such as the adsorption of phosphate by amorphous iro...

Nearly three decades of stable isotope ratios and surface mass balance (SMB) data from eight shallow firn cores retrieved at Fimbul Ice Shelf, East Antarctica, in the Austral summers 2009-2011 have been investigated. An additional longer core drilled in 2000/2001 extends the series back to the early eighteenth century. Isotope ratios and SMB from the stacked record of all cores were also relate...

Babi}, Lj. & Zupani~, J.: Major events and stages in the sedimentary evolution of the Paleogene Promina basin (Dinarides, Croatia). Nat. Croat. Vol. 16, No. 4, 215-232, 2007, Zagreb. A study of sedimentary successions in different parts of the Eocene-Oligocene Promina basin has revealed major changes in the evolution of upper Promina Beds (PB). The first one refers to the origin of the erosiona...

Forced ice-shelf oscillations modeling was undertaken employing a full 3D finite-difference model of an elastic ice shelf that coupled to treatment under-shelf seawater flux. The flux described by the wave equation, which includes pressure excitements in shallow water layer under shelf. Thus, flexure produced hydrostatic below-shelf seawater. Numerical calculations were performed for idealized ...

Since inferring spawning areas from larval distributions in the Sargasso Sea a century ago, the oceanic migration of adult American eels has remained a mystery. No adult eel has ever been observed migrating in the open ocean or in the spawning area. Here, we track movements of maturing eels equipped with pop-up satellite archival tags from the Scotian Shelf (Canada) into the open ocean, with on...

Abstract. Vertical shear is recognized today as a key component of the stress balance ice shelves. However, first shelf models were built on neglect vertical shear. Partly due to its historical treatment, it remains common discuss though still considered negligible in models. Here, we offer perspective changing treatment over time, and emphasize term's non-negligibility current modeling. We ill...

The Ross Sea is critically important in regulating Antarctic sea ice and is biologically productive, which makes changes in the region’s physical environment of global concern. We examined the effects of projected changes in atmospheric temperatures and winds on aspects of the ocean circulation likely important to primary production using a high-resolution sea ice-ocean-ice shelf model of the R...

The SeaBED autonomous underwater vehicle (AUV) is a new imaging platform designed for high resolution optical and acoustic sensing. This low cost vehicle has been specifically designed for use in waters up to 2000 m to carry out video transects, bathymetric and side-scan sonar surveys. In this paper we detail the systems issues associated with navigation, control, and imaging that led us to our...
