  2. Marine Sampling at Bouvetoya Island

    Marine Sampling at Bouvetoya Island
    Bouvetoya is known as the most isolated island in the world. The areas we chose for sampling have never been explored before...this can be said for many areas of the Sub-Antarctic, however, Bouvetoya is a particularly remote and rare place – cold, hostile and impenetrable. Despite this, chinstrap penguins and many different species of albatross call this place home. Image: Bouvetoya Island. Photo: B. Moreno There are very few biological samples from this area, and the only recent records of
  3. Marine sampling at Candlemas and Southern Thule in the South Sandwich Islands

    Marine sampling at Candlemas and Southern Thule in the South Sandwich Islands
    The South Sandwich Islands are a chain of volcanic islands in the Sub-Antarctic. This isolated, and as such rarely visited, and even more rarely sampled archipelago, is often sighted in stormy seas and dense cloud (as it was when Narissa visited in 2011, and when Rachel visited in 2012). Our first sighting of one of the northern islands, Candelmas, was similarly dreary. Image: Our first view of Candlemas Island. Photo: N. Bax Rachel was here at this craggy, volcanic, isolated place in 2012 on
  4. Benthic Trawling (and more) at Diego Ramerez

    Benthic Trawling (and more) at Diego Ramerez
    After a few days of ‘not-so-glassy’ sailing we arrived at the Chilean sub-Antarctic island group – Diego Ramirez. Made up of a group of northern islands, or islets, and a southern group, we spent our time in the south, offshore of Diego’s two largest islands: Isla Bartolomé and Isla Gonzalo. We arrived bright and early at 6amish, though, of course there had to be some kind of drama. This time it revolved around getting terrestrial people ashore without the required immigration clearance
  5. No marine sampling at Peter 1st Island

    No marine sampling at Peter 1st Island
    Enough time had been saved due to good weather and ice conditions in transit between sites to spend 4 hours at Peter 1st island.  As our winch was still not working and there was too much ice around we could not test the winch here so had the day off to enjoy the views of this magnificent ice capped monolith rising out of the ocean.  All up the ASCCC team spent 6 ours relaxing on the bow of the ship, watching the southern fulmars and skuas gracefully circle the ship and the crab eater seals
  6. Marine sampling at Mt Siple

    Marine sampling at Mt Siple
    Mt Siple is a little known volcano near the Amundsen shelf…BIG icy, cold, white.  This was an opportunistic site as ice conditions suggested we couldn’t get to Peter 1st - a rare sensible group decision that everyone bought into, and for most people it turned out to be an excellent decision…especially for those who went on to sample at Peter 1st as well. We conducted two trawls at the Mt Siple station. They were both exceedingly rich - by far the greatest diversity we have seen on leg two.
  7. Marine sampling at the Balleny Islands

    Marine sampling at the Balleny Islands
    Our first view of Young Island, the northern most point of the Balleny Islands, was misty, cold, windy and a little foreboding. It’s a spectacular, remote, inhospitable but stunningly beautiful area. At the North end of Young island, the cliffs overhang by imposing glaciers. Sea stacks are present....it made us think the bathymetry could be exciting - and our multi beam sonar indicated that there are similar stacks under the water. We were able to do six trawls with the entire benthic team
  8. Deep shelf sampling at the Mertz glacier

    Deep shelf sampling at the Mertz glacier
    Our first trawl on leg 2 of ACE was a collaboration of the two benthic teams together, the ASCCC team and the Marine Refugia team, with the Remotely Operated Platform for Ocean Science (ROPOS) remote operated vehicle (ROV) team.  Our first trawl net came up from 650 m full of ophiuroids, giant sponges, polycheates (worms with legs) and corals…which took some time for the extended team to sort - and we did so with such enthusiasm that time flew by in the lab below deck. Hours later we
