An explosion incidence  can  be    possible according  registered  data.  Searching of  the submarine is going on under  difficult circumstances, stormy weather,  waves can be 8 meter high. The  sea bottom  along Argentine coast line has also very peculiar  complex geomorphology   with  a   steeps towards abyssus , where no  rescue is possible.  Searching  is made in   frames of possibilities and probabilities.   Enormous international  searching operation  is going.

Abstract

In the framework of the Vulnerable Marine Ecosystems (VME) of the High Seas of the South West Atlantic, large areas of the Argentine Continental Margin (ACM) between 44°30’S and 48°S have been swath-mapped for the first time, obtaining full data coverage of the seafloor in this region between the outermost continental shelf and the middle slope down to 1600 m water depth.

The slope is characterized by the presence of smooth terraces (Nagera, Perito Moreno and Piedra Buena) that widen towards the south, limited by morphological steps with evident signs of erosion in the form of scours. These terraces form part of the Argentine contourite depositional systems, generated by the interaction of the northwards flowing Antarctic water masses with the seafloor. Within the studied area, seven canyons and their multiple branches dissect the upper and middle continental slopes, from west to east, across the terraces and the steps.

 

These canyons, which belong to the Patagonia submarine canyon system and are collected at a depth of ~ 3.5 km by a slope-parallel, SSW–NNE-oriented channel known as the Almirante Brown transverse canyon, display a large variety of morphologies. These include incisions from just a dozen of metres to 650 m, straight to highly meandering sections with sharp bends, well-developed levees and walls that reach 35° in slope gradient, hanging branches, conspicuous axial incisions and multiple knickpoints. Only the northernmost canyon indents in the continental shelf, whereas the others start at the limit between the upper and middle slopes, and are often fed by small, straight, leveed gullies.

The action of both across-slope processes represented by submarine canyons and along-slope processes represented by terracing and scouring conform the ACM as a peculiar mixed margin, with the presence of both contour and gravity currents at the same place at the same time. We propose that at present, along-slope erosion and transport mainly occurs along the Perito Moreno terrace, whereas across-slope processes are much more dominant in the Nagera terrace. Erosive bedforms such as crescent scours, generated by contour currents, contribute to the progressive bottom-up erosion of the Nagera terrace and act as an initial collector of across-slope transported sediment, that later, due to flow focusing and recurrence, incise and interconnect creating definitive canyons that progress upslope by retrogressive erosion until their head indents the shelf break.

Changes in the balance between across-slope and along-slope transport would imply a disequilibrium in the combination of processes leading to canyon formation, producing canyon abandonment, and partial or total filling. These changes could be produced by a variation in the depth of the main interfaces of Antarctic water masses leading to either an increase or a decrease in the erosion and transport capacity of contour currents, and/or by an enhancement of across-slope transport related to an increase of sediment availability.

Perhaps its better to take a link to Wahis to get an insight to other viruses also and the relevance of this one.

The Finnsih Army lost three young man who were on their military service,
A serious traffic accident between the army car and a speedy light train on railroad happened in very bad weather. One passenger in the train died. Four seriously injured are still in the hospital and six injured persons could already leave the hospital. The grade crossing was simple, without warning lights or booms.

Karolinska Institut-forskaren Ahmadreza Djalali, som hållits fängsladn i Iran sedan april förra året, uppges ha dömts till döden.
Sverige har lyft frågan till högsta diplomatiska nivå, sa utrikesminister margot Wallström (S) i SVT:s Agenda i söndags kväll.
Med anledningen av dessa allvarliga uppgifter tar vi omedelbart upp detta med iranska företrädare på hög nivå. Sveriges liksom EU:s inställning till dödsstraffet är välkänd . Vi fördömer tillämpningen av dödsstraff i alla dess former, skriver hon också i en kommentar till TT.
AHMADREZA DHALALI greps under en resa i hemlandet Iran i april förra året, anklagad för spioneri.
Rättegången inleddes i slutet av augusti . Nu uppges alltså, enligt uppgifter i Expressen, en dödsdom ha utfärdats.
Vid denna tidnings pressläggning på måndagen kunde utriksedepartementet ännu inte officielt och till fullo bekräfta uppgifterna omatt ett dödsstraff utfärdats eller med säkerhet säga huruvida det kommer att verkställas. För SVT Nyheter uppger UD dock att man agerar utifrån den information som finns.
AHMADREZA DJALALI, som disputerade i katastrofmedicin vid karolinska institutet 2012 har permanent uppehållstillstånd i Sverige och är bosatt i Stockholm med sin familj. Att han inte är svensk medborgare har inneburit svårigheter att följa hans fall, uppger Patric Nilsson, presstalesperson vid UD, för Sveriges Radios Ekot.

Dr. A Dhalali was giving lessions in Iran  to his own  beloved people about Emergency Medicine and was prisoned there  (  why???)   in April 2016 and now according the Swedish News  to doctors ,   facing  exec ution. His family in  Stockholmis  waiting him home to Sweden, so even  Swedish  doctors. Why should some of  Iiranians  kill  Irans´ own  scientist, who  offers his knowledges to  his own peoople?
