The mv Ortelius voyage made it as far south as 69 degrees and 49 minutes latitude.
We took the zodiacs out early one morning in Lazarev Bay and headed south to find the remnants of the Wilkins Ice Shelf. Not all zodiacs were burning fuel at the same rate due to some not being able to ride the plane. As a result, after over 2 hours and the ice shelf visible in the distance, we had reached as far as we could go and still have enough fuel to return to the ship.
In January 2008 the ice shelf covered an area of approximately 5,300 square miles. However, by March a section measuring about 160 square miles had collapsed, leaving a thin bridge of continuous ice connecting the ice shelf to Charcot Island. The shallow mouth of the bay has left thousands of icebergs stranded, making Lazarev Bay a unique and special place. Waking up that morning to the glorious weather and icebergs as far as you could see in every direction is a memory I won't soon forget.
Some of the waters we traversed in that bay were unchartered, which called for a zodiac traveling ahead of the ship to determine the depth. That way of travel makes for slow going.
There are islands in that bay that were visited that don't exist on any map.
As far as the diving goes, we weren't diving any known sites. I don't think anyone has ever dove some or even all of those sites. Water temperature ranged from 32 - 36 degrees F and the water visibility was poor; most of the time less than 10 feet. That time of year (Austral summer), there is a lot of phytoplankton in the water, and maybe even more than usual this year. The air temperature never got below freezing, but the wind chill at times sure made it seem so.
All of the diving was off zodiacs without ladders. While we had experienced dive guides piloting the zodiacs, these were not guided dives. Some of the highlights included diving while a pod of humpback whales were close by -- at times within a few feet -- and diving an iceberg.
The scientific aspects of the expedition were deemed a success. We had the Collections Manager of Echinoderms for the Los Angeles Natural History Museum with us and she was able to take home 534 lots of specimens collected by the divers for further examination, with at least one new suspected species.
There were other interesting scientific projects running, involving microplastics and microfibers, a new underwater acoustic device, and low frequency radio communications.
I have more to say about this trip including the diving for those thinking about diving in Antarctica, but I just arrived back home earlier this morning after an overnight flight and reality intrudes. There will be a ship log released within the next week or two by Oceanwide Expeditions that will include a slide show and I'm not sure what else. I'll curate what they release along with pictures taken by myself and others in the group and post some of it up.
Where it all began: In Ushuaia at the "end of the world."
