First ever underwater guided tour of HMS Erebus

In a video streamed live from the Queen Maud Gulf off Nunavut, underwater archaeologist Ryan Harris moved from stern to bow, stopping at a handful of different points along the wreck to share clues from the long-sunk vessel.

He started by inspecting two brass six-pounder canons, one of the first features the team saw with a remotely operated vehicle when they began inspecting the site with an “underwater robot”, after the 19th-century wreck was discovered late last summer.

According to study leader Dr Yuuki Watanabe of the National Institute of Polar Research, Japan, "The physiological mechanism of keeping heat in the body is well understood. But, more a fundamental question is, why this unique evolution occurred in the first place. In other words, what kind of advantages does the fish gain from being warm-bodied?"

Bottles of champagne salvaged from a 170-year-old shipwreck have been tested by scientists.

The new study, published in the journal PNAS (Proceedings of the National Academy of Sciences of the United States of America), reports "chemical and sensory analysis" of the historic liquid. It was led by Prof Philippe Jeandet, from the University of Reims in Champagne-Ardenne, France.

Norwegian Coastal Administration locates 15 more WW2 wrecks in Skagerrak

During a survey in 2009, the Norwegian Coastal Administration (NCA) located some twenty wrecks in the area. A recent search revealed an additional 15 wrecks, taking the total to at least 35.

Most of the wrecks stem from the post-WW2 scuttling, but there were also some that we could not associate with this campaign, said chief scientist at Norway's Defence Research Institute, Petter Lågstad.

Some of the wrecks were obviously unrelated to the scuttling because of their size and age.
