Present-day circulation patterns in the southeastern Pacific Ocean are driven by Antarctic Circumpolar Current, directing subantarctic surface water into Patagonian fjords since at least early Holocene. In this way, bottom current area regulated regional climate, although complex bathymetry of has a significant impact as well. To understand potential interplay seafloor topography and patterns, ...

Assessing the impact of glaciations on topography and co-evolution ice-sheet dynamics requires a thorough understanding factors that control fjord morphology. We investigate role lithology glacial valley form using topographic analyses numerical landscape evolution models. measure depths widths from East Central Greenland (68°N–75°N), find width, with wider fjords in softer rocks (i.e., sedimen...

Like the arms of a dancer, which are waved following rhythm music but avoid colliding with her head or body; flexible expanded helicenes find different pathways to reverse their position depending on size and nature insert placed in innermost zone fjord. This work presents synthesis series in-fjord substituted an estimation inversion barriers through state-of-the-art quantum calculations. Inter...

Heat, freshand sea-water balances indicate that the late-summer rate of submarine melting at the terminus of tidewater LeConte Glacier, Alaska, U.S.A., in 2000 was about 12mdw.e., averaged over the submerged face. This is 57% of the estimated total ice loss at the terminus (calving plus melting) at this time. Submarine melting may thus providea significantcontribution to the overall ablationof ...

Submarine melting at the ice–ocean interface is a significant term in the mass balance of marine-terminating outlet glaciers. However, obtaining direct measurements of the submarine melt rate, or the ocean heat transport towards the glacier that drives this melting, has been difficult due to the scarcity of observations, as well as the complexity of oceanic flows. Here we present a method that ...

The baroclinic tidal regime of the fjord Loch Etive (Scotland) is studied. Analysis is performed on the basis of both in situ data and numerical simulations, with the use of a fully nonlinear nonhydrostatic fine-resolution model. It was found that the crest of the sill that separates Loch Etive into inner and outer parts is subjected to a supercritical flow regime with maximum Froude numbers in...

Abstract Tidewater glaciers are an important and difficult part of the cryosphere to study owing their complex nature often inaccessible physically challenging environments. The interaction glacier fjord processes furthermore presents particular observational challenges. Modelling provides a possible solution these issues, but, at scale, processual complexities require 3-D full-Stokes approach ...

A temporal change in the stable isotope (SI) composition of jellyfish in the Kiel Fjord, Western Baltic Sea, was documented by analyzing δ13C, δ15N and δ34S of bell tissue of Aurelia aurita and Cyanea capillata in the period between June and October 2011. A strong and significant temporal change in all SI values of A. aurita was found, including an increase of ~3 ‰ in δ13C, a decrease of ~4 ‰ i...
