Подводные археологи исследуют Карантинную бухту в Севастополе
Экспедиция отдела подводной археологии Государственного музея-заповедника “Херсонес Таврический” в осеннем сезоне 2017 года продолжает работу в акватории Карантинной бухты, сообщает ИА SevastopolMedia.
Разведки выявили в кутовой части бухты огромное количество однотипного керамического материала, представленного, в основном, фрагментами амфор VIII-IX вв. Подводные исследования в этом районе позволили получить профильные образцы амфор, а также фрагменты глиняной обмазки гончарных печей.
Среди археологического материала встречены фрагменты бракованных и явно деформированных изделий. Это подтверждает данные наблюдений 50–70-х гг. археологов, позволивших предположить наличие на берегах бухты крупного гончарного производства.

РАННИЙ СНЕГОПАД В ПРОВИНЦИИ ГАНЬСУ (КИТАЙ)


Ранний для данного региона снегопад прошел в понедельник в китайской провинции Ганьсу, нарушив привычный ритм жизни и причинив ущерб фермерам, сообщает телеканал CCTV.
В уезде Цзинтай выпало до 25 см снега. Ветки деревьев под тяжестью снега ломались и падали на дороги, в результате чего было нарушено движение транспорта.
Кроме того, многие автомагистрали покрылись коркой льда, а резкое снижение температуры воздуха привело к образованию густого тумана. Местами видимость упала до 50 метров.

That may have hurt.


This is a 1.85 billion year old stromatolite. Stromatolites are colonies of single celled organisms; they grow outwards over time layer by layer and incorporate sediments into them, basically forming a rock that grows outwards. This colony grew outwards until something rather disruptive happened. This stromatolite is found in the Sudbury breccia; a unit of shattered and busted up rocks formed 1.85 billon years ago when an asteroid slammed into what is today Canada.
