The most complete inbis channel map released subsea world news electricity bill saudi electricity company


This channel is one of the few submarine valleys in polar latitudes that kept its geological architecture during the Last Glacial Maximum (LGM), according to the new study published in the journal Arktos – The Journal of Arctic Geosciences, in which the lecturer José Luis Casamor, member of the Consolidated Research Group on Marine Geosciences of the Faculty of Earth Sciences of the 7 gas station University of Barcelona takes part.

Many unknown landscapes in our planet are under oceanic waters. Nowadays, sea floors and polar regions build up two big frontiers for research in the field of Earth Sciences. In this context, the application of advanced technologies in scientific campaigns –differential GPS, high resolution multibeam bathymetry, 2D and gas refrigerator not cooling 3D reflection seismic imaging, remotely operated underwater vehicle (ROV)- was a methodological revolution that broadened the precision of bathymetry maps in sea floors.

ters below the marine surface. INBIS is regarded as “ an exceptional deep marine channel in polar latitudes, which was formed in an area of the continental margin between two important trough mouth fans (TMFs)”, notes José Luis Casamor, co-director of the Oceanographic campaign DEGLABAR, which mapped great part of the INBIS channel in the oceanographic ship OGS Explora in 2015.

Over thousands youtube electricity of years, the submarine relief of this channel has been shaped by the action of several geological processes in polar margins. The gullies are the main topographic structures “that enabled the geological reconstruction of INBIS channel”, notes Leonardo Rui, member of the Trieste National electricity images cartoon Institute of Oceanography and Experimental Geophysics (OGS) and first author of the study.

A similar case would be the Albertini Through, in the northern margin of the Svalbard Island archipelago, in the Arctic Ocean. “In this area, the external shelf receives sediments brought by ice currents that flow through the Albertini Channel, a process that prevents the formation of a TMF and allows the formation of a submarine channel”, says Leonardo Rui.

In the upper part of the INBIS channel, the new bathymetric map describes a system of gullies and minor channels –among which are the TMFs of Kveithola and Bear Island- that cut the continental slope and end up running into the main channel. According to the study, the action of density currents and turbidity currents created by fusion ice water are factors zyklon b gas canister for sale that shaped and kept these erosive structures.

The change in the slope gradient is another key electricity physics definition factor for the submarine topography that has to be considered when determining the origins of the submarine relief of the IBIS channel. According to Leonardo Rui, “this factor, together with changes in dimensions of gullies, led to a distinction of an area partially subjected to the flow of glacigenic debris flow (southern area) and a fully protected area by the proximity to the Bear Island (northern area)”.

The geological history of the Arctic Ocean revealed extreme episodes such as the Storegga Tsumani, the o goshi most spectacular submarine disaster known so far, which shook polar sea floors about 7,000 years ago. In the Fram Strait –a passage between Greenland and the Svalbard Islands- the Arctic cold waters mix with the Atlantic warm waters and create an exceptional situation to study the geological records of the natural climate change in the planet.

Now, the northern polar waters –one of the most affected ecosystems by the effects of global change- build a perfect natural laboratory for many fields of marine geosciences (geomorphology, paleoceanography, paleoclimatology, bathymetry, etc.). In this scenario of challenges for international sciences, the Consolidated Research Group on Marine Geosciences of the UB –led by Professor Miquel Canals- has been distinguished for its research studies’ scientific impact, focused on revealing the geological and paleoclimate history of marine seafloors, which have been gas definition state of matter dominated by the action of great caps and ice currents for thousands of years.
