By 12,000 years ago, the ice sheet was gone, leaving episodes of stream erosion so that only a horizon line as sediment on tropical sea floors between 300 and 550 behind a poorly drained landscape of pebbly deposits of hill summits marks the once-continuous glacial plain. -

Translitterering Och Alternativa Geografiska Namnformer
TRANSLITTERERING OCH ALTERNATIVA GEOGRAFISKA NAMNFORMER Version XX, 27 juli 2015, Stefan Nordblom 1 FÖRORD För många utländska egennamn, i första hand personnamn och geografiska namn, finns det på svenska väl etablerade namnformer. Om det inte finns någon sådan kan utländska egennamn dock vålla bekymmer vid översättning till svenska. Föreliggande material är tänkt att vara till hjälp i sådana situationer och tar upp fall av translitterering1 och transkribering2 samt exonymer3 . Problemen uppstår främst på grund av att olika språk har olika system för translitterering och transkribering från ett visst språk och på grund av att orter kan ha olika namn på olika utländska språk. Eftersom vi oftast översätter från engelska och franska innehåller sammanställningen även translittereringar och exonymer på engelska och franska (samt tyska). Man kan alltså i detta material göra en sökning på sådana namnformer och komma fram till den svenska namnformen. Om man t.ex. i en engelsk text träffar på det geografiska namnet Constance kan man söka på det namnet här och då få reda på att staden (i detta fall på tyska och) på svenska kallas Konstanz. Den efterföljande sammanställningen bygger i huvudsak på följande källor: Institutet för de inhemska språken (FI): bl.a. skriften Svenska ortnamn i Finland - http://kaino.kotus.fi/svenskaortnamn/ Iate (EU-institutionernas termbank) Nationalencyklopedin Nationalencyklopedins kartor Interinstitutionella publikationshandboken - http://publications.europa.eu/code/sv/sv-000100.htm Språkbruk (Tidskrift utgiven av Svenska språkbyrån i Helsingfors) Språkrådet© (1996). Publikation med rekommendationer i term- och språkfrågor som utarbetas av rådets svenska översättningsenhet i samråd med övriga EU-institutioner. TT-språket - info.tt.se/tt-spraket/ I de fall uppgifterna i dessa källor inte överensstämmer med varandra har det i enskilda fall varit nödvändigt att väga, välja och sammanjämka namnförslagen, varvid rimlig symmetri har eftersträvats. -

Reidentifying Depositional, Solifluction, “String Lobe” Landforms As Erosional, Topographic, Steps & Risers Formed by Paleo-Snowdunes in Pennsylvania, USA

Vol. 10, No. 3, 2021, pp. 136-144. doi: 10.11648/j.earth.20211003.19 Received: May 13, 2021; Accepted: June 9, 2021; Published: June 30, 2021 Abstract: A controversy arises concerning relict, ubiquitous, depositional, solifluction, “string lobe” landforms in the Ridge and Valley province of Pennsylvania, reported by other investigators. A distinguishment is made here by defending an original interpretation of the particular landforms which identified these as snowdune meltwater-eroded depressions formed within colluvium during cold phases of the Pleistocene Epoch. Hence, the landforms are reassessed as “steps & risers” in this study which is jargon associated with nival erosion. The reidentification is warranted in the study because of multiple lines of evidence including: the landforms’ detailed geomorphology and sedimentology; the landforms having a highly, unusual, very repetitive, NE-SW orientation; and the landforms incurring a striking, gravity-defying, characteristic of running-water erosion repeatedly occurring irrespective of the steepest part of the general slope. Besides the evidence offered here, the study also gives insight, resolutions and re-confirmations in order to establish absolute identification while differentiating between discussed, periglacial, relict landforms. -
Passage Through Siberia a River Cruise Along the Mighty River Lena to the Arctic Aboard the MS Mikhail Svetlov 18Th August to 2Nd SEPTEMBER 2015 Scottintsy
PASSAGE THROUGH SIBERIA A river cruise along the mighty River Lena to the Arctic aboard the MS Mikhail Svetlov 18TH AUGUST TO 2ND SEPTEMBER 2015 Scottintsy he vast untouched regions of Siberia offer a unique travel experience for the genuine traveller. The scarcity of roads and railways means thatT the most common method of transportation is by river. The Lena, one of the mightiest rivers in the Russian Federation, flows through the Yakutia-Sakha Republic in north-east Siberia into the Arctic Ocean. During this unique river cruise we will sail through unspoiled natural scenery, taking a short detour to the Lena Pillars National Park before continuing downstream to where the river meets the Arctic Ocean at the polar harbour of Tiksi before heading back to Yakutsk. From the comfort of your floating hotel, the MS Mikhail Svetlov, you will see the landscape slowly change from verdant taiga to polar tundra and enjoy the magical “white nights” in a place where the sun barely sets in summer. One of the most fascinating aspects of the cruise will be the opportunity to visit the people in riverside settlements along the way. Their culture, lifestyle and language will be a constant source of wonder especially their ability to thrive in the most hostile of environments. During the cruise there will be a series of fascinating onboard lectures on the former USSR, icon painting, relations between Russia and her neighbours and Russia’s great rivers. Itinerary Highlights • “White nights” in the Arctic Circle • The legendary Lena Pillars • Unspoiled tundra and taiga scenery • The Lena River Delta and the Arctic Ocean • Ethnographical open-air museum in Sottintsy • Authentic folklore performances Yakutian Children Tundra Wildflowers www.noble-caledonia.co.uk Day 9 Tiksi.
