At daylight we began preparations for our first attempt at a 1-m Mocness tow in nearly three weeks. Unfortunately the tow was not as successful as we would have hoped - the catch consisted of only a few juvenile krill and the Mocness was slightly damaged in a collision with an ice floe. Repairs were made as necessary and we conducted another tow in the afternoon but no more adult krill were caught. We are anticipating an arrival at Palmer Station around noon tomorrow.

Prior to departure we completed a CTD cast and then steamed to the north looking for leads that would allow us to move to the east. It was slow going. We had to back and ram multiple times and our speed averaged only 2 knots. When we left our process station we were 17 miles from our planned waypoint and when we shut down in the evening we had 11 miles left to the waypoint. During the night we had considerable winds from the NE such that by morning when we started again we were now 22 miles away from our waypoint!

I wasn't cc'ed when Jesse sent out the staffing schedule. However, the ship's schedules I received have a staffing schedule attached. This should suffice for now. Thanks!

As an experiment we erected a Scott tent over one of the two dive holes. Overnight, there was enough freezing on the unprotected hole to walk across while on the covered hole the ice was so thin you could put your finger through it. The tent also provided shelter against the wind for the tenders and helped to cut down on glare and visual shock for the divers coming out of a darker environment. Air temperatures continue to be cold, but offshore winds should help relax the ice pack making it easier for the LMG to move about the area under its own power.

In the process we became stuck for several hours in an area of ice pressure and active ridging. Around midnight we broke free and hove to in an area of thinner ice. At first light we identified a suitable floe for ice collections and diving operations and set up camp. At approximately 15:00 we were forced to pull up stakes once again as winds caused the ship to move to starboard and crack the working floe. However, we were able to complete one dive and an ice thickness transect before we had to move. Karl Newyear Raytheon Polar Services Company Marine Projects Coordinator ARSV Laurence M.

We pulled up our stakes but left the complex CRREL buoy in place to be recovered during NBP 01-5. Upon moving approximately 1.5 km from our previous work site we conducted a CTD cast and decided to find a suitable site for about 2 days more work. While doing so we came across a group of Adelie penguins and a seal. Teams are currently preparing to go onto the ice to collect samples and it is likely we will stay in this immediate vicinity for the forseeable future.

The air temperatures have risen considerably but snow is accumulating. This depresses the ice under its weight and leads to intrusion of seawater and re-formation of a slush layer between the dry snow and the sea ice. Due to limitations on the LMG we have altered our science plan so that we will move to the northeast of here rather than the southwest in about 2.5 days.

Every group was able to collect samples except for those seeking penguins or needing to tow the Mocness. We even cut a hole in the ice to allow a CTD cast to be completed. A precipitous drop in air temperature and wind speed helped make operations more comfortable today than yesterday.

The past 24 hours have brought highly variable winds and dropping temperatures. Colder weather is a blessing because it allows us to sample ice throughout the freezing process. It also freezes the 10 cm slush layer on top of the ice so we don't have to slog through ankle-deep slop to get to the sampling sites. Ice and wind conditions have prevented us from continuing to use the CTD hole that we cut in the ice yesterday; we are unable to reliably keep the hole aligned with the Baltic door. It has been a rather slow science day with the ice collectors being the most active group. No workable seals or penguins have been sighted.

Today we sent a party ashore on Emperor Island, part of the Dion Islands, to visit a penguin colony there. This is the northernmost known breeding colony of emperor penguins and the only place where that species is known to breed on land. 10 males, 9 with eggs were sighted; the females are at sea feeding this time of year. This is approximately half the number of birds seen in the same place two years ago. Workable seal sightings remain few and far between.

The LMG crossed 60* S latitude earlier this morning, and this afternoon we sighted first ice. There were loose bands of heavily decayed brash ice near 62* 10' S. Daily radio comms between the LMG and both Palmer Station and the NBP continue. Anticipated arrival at Palmer Station is 18:00 local time tomorrow (Wednesday).

We are not conducting an XBT transect during this cruise. We have exited the sheltered waters of the Strait of Magellan and the east coast of Tierra del Fuego, so there is more ship motion than before. It feels good to be back at sea!
