Questions & Answers

Well, we're off again: we left Stanley on West Falkland Island last night at midnight, heading back to Station 12 (go to to view the cruise track), about 15 hours steaming, where we hope to collect some Champsocephalus esox, a smallish icefish species that most of the scientists on board want to study.

Next landfall will be Shag Rocks, west of South Georgia. No shore leave there; just a bunch of oddly shaped rocks sticking up out of the water. Along the way we should be able to make some deep tows to at least 3000 meters (9750 ft.).

While we were in Stanley, we got some new trawls shipped from Punta Arenas to replace those we damaged badly or lost. One of these is set up for use on rougher bottom and we are using it now to try to get esox. We are working at a station between the islands of East and West Falkland where local fisheries scientists have told us we should be able to get it, but so far have had no luck. We will make tows progressively farther to the south at increasingly greater depths and should be successful. We have made one tow so far (shallow, at 70 m or 227 ft.) and caught very few fish but thousands of crab krill, a small crab that looks like crayfish. So, we have the net out now in somewhat deeper water. Catching esox is extremely important to the success of our cruise because it is needed for so many analyses.

Our two days in Stanley were great! The Falklands are a really spectacular place, the people (total about 2400 in all the islands) are very friendly, spectacular wildlife and history is easily accessible, and we got many of the shallow-water fish that folks needed for their research. I didn't actually get out of town, although I walked around quite a bit, but others went seining in some small estuaries for galaxiids and some nototheniid fishes and also trawled from our two inflatables. The galaxiids are native to the Falklands, and are related to salmon and trout. The nototheniids (Eleginops maclovinus), which the locals call mullet, are not mullet at all but have evolved to sort of look like carp, although they live in cold, clear water. They are distinct enough from the other nototheniid species that they will probably be considered as a separate (but related) family in the near future.
