All the best for the new year.

We have finally made our way through the maze of ice fields and into the Ross Sea.

It has taken us 6 days to cover 300 mile of longitude to the south. In that time we probably traveled around 1,000 nautical miles as we weaved our way along leads, around ice bergs, between ice floes and through broken melt ice as we searched for the safest track in.

But it’s all worth while now that we are on the fishing grounds and enjoying some good calm weather conditions that are typical in the Ross Sea for this time of year.

When the ice bridge finally thaws, in another 2 or 3 weeks, the weather pattern will change again and allow some of those Southern Ocean low pressure systems to track further south. Until then, we are quite happy with sea conditions that you are more likely to find on a lake than here in Antarctica.

I find it difficult to describe the many different sights we see in these waters, even though its all just ice. Anyway, we all just keep clicking off photos and hope a good one comes up now and then.

I’ll have some fishing photos soon.

Ps: There were 4 commitments to knock off smoking as a new year resolution.

We’ll see how that goes in the next few days.

Yesterday afternoon CCAMLR issued notification to all vessels that areas B,C and G would be closed to all fishing at midnight 22nd December 2008. After that time we must make all efforts to haul our lines from the water and cease fishing in this area. Now all vessels are faced with the same dilemma, how to get access from the northern grounds to the southern grounds in the Ross Sea when there is still 360 mile of slowly melting sea ice between here and there. Indications that we have from satellite images are showing several possible tracks that we could take. But for now we must wait for at least a few days as more information comes in so we can find the safest course through the maze of leads and open water.

At least we will have plenty of down time to enjoy a good Christmas dinner without having to rush away on deck to start our shifts.

One of the most fascinating things to come across in Antarctic waters, are “Jade” ice bergs. I have attached some photos of the only Jade bergs that I have seen in 10 years of fishing these waters. Hopefully we get to see another one this season. Try and Google (Jade icebergs) they are fascinating.

Hi and thanks to everyone who have sent messages to the crew, some from family and others from people we don’t know. Whenever comments come in we post them on the mess room bulkhead and its amazing to see how the crew respond to a connection from back home. Again, thank you, and we’ll do our best to reply to all when we get the chance.

The weather has cleared today and we have 2 lines in open water north of the ice edge. This is not the spot we want to fish, that area is still ice covered at this stage so we’ll have to be content fishing on the northern hills for a few more days yet. Its better than looking at the big white monster (the pack ice) as we call it.

Today we crossed the magic line into the Antarctic Circle at:
66 35s and 177 30e.

Little by little we’re working our way south toward one of our favorite fishing spots, in past seasons we have done quite well there, obviously I can’t tell you exactly where it is, it’s a secret. One of the best things about this area is the easy ground for our lines to settle on, unlike areas to the north where the rocky bottom is a problem and stuck lines, huge tangles and strong currents can be dangerous for the crew in the hauling room.

During the last 10 days we’re seeing more and more sea ice and ice bergs as we move south. On the last count we had 10 large ice bergs on our 12mile radar range and 7/10th first year sea ice. To navigate in 7/10th sea ice it’s a bit like following a gigantic maze that zig zags for hundreds of miles with just as many dead ends. When we come to the end of a lead (the term used for an open track in the ice) we must turn back and look for another track or lead that will hopefully takes us in the general direction that we need to go. Sometimes this process takes days or even weeks depending on the season and how the ice is thawing, or isn’t with some seasons.

Many factors govern the rate that sea ice thaws. The obvious ones are, water temp, air temp, (sunny days are good but few and far between) wind strength and direction, sea swell, tidal movement and the east setting Southern Ocean Currents all combine to break the ice up. We receive the most up to date satellite images daily from our support team back home and we can also access the National Ice Center web sight for more information if needed. Check it out at

then click on Ross Sea Central and you can sort of see where we are on the big picture.

For now we are just stooging along, setting the odd line in clear water as we find it while we wait for the ice condition to open up and allow easy access into the Ross Sea.

The leads are small now but growing fast

The photos were taken during the last few days. One shows a small lead toward the south and the other is ice too thick for us to enter.
