    The Navy built a ‘fast, agile’ warship for $440M. It’s been stuck in ice since Christmas Eve - The Washington Post - January 22, 2018

    A recent Naval ice chat has revealed that the Swedish FRP sandwich Visby-class Corvettes, with the same propulsion systems as the high-strength steel hulled USS Little Rock, are pretty capable in ice, so they would probably have escaped before they were confined in that situation.

    The concerning ice chat was on the tread ‘‘Planning a workboat build’’ ---> post #16 to #18 hitherto.

    It could also be a matter of capabilities of the crew, in that case some US Navy Officers could do a course in Sweden, after all they're good friends...

    Yup, that's the part I was talking about. While we wait for it to snap off we could put a wall along its Eastern front. :D o_O

    Hmm , interesting coverage in Wikipedia suggests a bit of multi-method dispersal.

    "The ancestors of marsupials, part of a larger group called metatherians .... The oldest metatherian fossils are found in present-day China.[39] About 100 mya, the supercontinent Pangaea was in the process of splitting into the northern continent Laurasia and the southern continent Gondwana, with what would become China and Australia already separated by the Tethys Ocean. From there, metatherians spread westward into modern North America (still attached to Eurasia), where the earliest true marsupials are found. .... Marsupials reached Australia via Antarctica about 50 mya, shortly after Australia had split off. This suggests a single dispersion event of just one species, most likely a relative to South America's monito del monte (a microbiothere, the only New World australidelphian). This progenitor may have rafted across the widening, but still narrow, gap between Australia and Antarctica."

    So, the ancestors of marsupials started in China/Australia, and possibly RAFTED back to Australia .

    Thanks for digging it up Ray, one can never have enough knowledge about the history of Marsupials, as they are ( or only were ? ) true seafarers . . :)

    When did the Tasmanians arrive?

    ‘‘ The Devil Cat is one of Incat Tasmania’s fast ferry wave-piercing catamarans and was built at their Hobart shipyard in 1997. It has a capacity of 900 passengers, 240 cars and the ability to maintain fully loaded service speeds of 43 knots, or 80km/h. At lightship condition, Devil Cat has achieved 50.2 knots, or 93 km/h. The catamaran is operated by TT Line Company Pty Limited on their ferry service from Melbourne, Australia, across the Bass Strait to Tasmania. ’’

    Though I'm not sure if this Devil nowadays is still enroute between Tasmania and Victoria.​

    NO. THANK GOODNESS !

    They were terrible. I know Cliff the designer has won the Blue Riband trophy a few times, but the old ferries got nicknamed "Spew Cats"

    I travelled on them a couple of times, and participated in a passenger survey about how dreadful they were, before they were replaced by conventional ferries.

    They were a terrific example of great technology solution but dreadful passenger results.

    I meant the aboriginal Tasmanians :D , but I found the answers interesting. Side note: I had a cousin named Hobart and have a friend also named that.

    Wikipedia is the solution

    "Until the 1980s, it was thought that Tasmania was only occupied relatively recently, but the discovery of 19,000-year-old deposits at Kutikina (or Fraser) Cave demonstrated the Ice Age occupation of the highlands.[14] In 1990, archaeologists excavated material in the Warreen Cave in the Maxwell River valley of the south-west, proving Aboriginal occupation from as early as 34,000 BP, making indigenous Tasmanians the southern-most population in the world during the Pleistocene era."

    Edit

    Even more interesting. something I didn't know t hat is :)

    "Before Present (BP) years is a time scale used mainly in geology and other scientific disciplines to specify when events occurred in the past. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date of the age scale, reflecting the fact that radiocarbon dating became practical in the 1950s. The abbreviation "BP", with the same meaning, has also been interpreted[1] as "Before Physics"; that is, before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, making dating after that time likely to be unreliable.[2][3]

    Huh. That is interesting. I think I will stick with A.D.(Anno Domini).

    CE and BCE works for me.

    Common Era or Current Era (CE)[1] is a name for a calendar era widely used around the world today. The era preceding CE is known as before the Common or Current Era (BCE). The Current Era notation system can be used as an alternative to the Dionysian era system, which distinguishes eras as AD (anno Domini, "[the] year of [the] Lord")[2] and BC ("before Christ"). The two notation systems are numerically equivalent; thus "2018 CE" corresponds to "AD 2018," and "400 BCE" corresponds to "400 BC".[2][3][4][a] Both notations refer to the Gregorian calendar (and its predecessor, the Julian calendar). The year-numbering system as used for the Gregorian calendar is the most widespread civil calendar system used in the world today.

    The expression has been traced back to 1615, when it first appeared in a book by Johannes Kepler as the Latin usage vulgaris aerae,[5][6] and to 1635 in English as "Vulgar Era". The term "Common Era" can be found in English as early as 1708,[7] and became more widely used in the mid-19th century by Jewish academics. In the later 20th century, the use of CE and BCE was popularized in academic and scientific publications, and more generally by authors and publishers wishing to emphasize secularism or sensitivity to non-Christians, by not explicitly referencing Jesus as "Christ" and Dominus ("Lord") through use of the abbreviation[c] "AD".[9][10]

    7000 year old Indian Village ?
    Bollocks.
    The Earth is only 7000 years old, and Adam and Eve would still have been running around the garden.
